Ralph for Claude Code

Autonomous AI development loop with intelligent exit detection and rate limiting

Ralph is an implementation of the Geoffrey Huntley's technique for Claude Code that enables continuous autonomous development cycles he named after Ralph Wiggum. It enables continuous autonomous development cycles where Claude Code iteratively improves your project until completion, with built-in safeguards to prevent infinite loops and API overuse.

Install once, use everywhere - Ralph becomes a global command available in any directory.

Quick Start

Ralph has two phases: one-time installation and per-project setup.

text

INSTALL ONCE              USE MANY TIMES
+-----------------+          +----------------------+
| ./install.sh    |    ->    | ralph-setup project1 |
|                 |          | ralph-enable         |
| Adds global     |          | ralph-import prd.md  |
| commands        |          | ...                  |
+-----------------+          +----------------------+

Phase 1: Install Ralph (One Time Only)

Install Ralph globally on your system:

bash

git clone https://github.com/frankbria/ralph-claude-code.git
cd ralph-claude-code
./install.sh

This adds ralph, ralph-monitor, ralph-setup, ralph-import, ralph-queue, ralph-migrate, ralph-enable, and ralph-enable-ci commands to your PATH.

Note: You only need to do this once per system. After installation, you can delete the cloned repository if desired.

Phase 2: Initialize Projects (Per Project)

Option A: Enable Ralph in Existing Project (Recommended)

bash

cd my-existing-project

# Interactive wizard - auto-detects project type and imports tasks
ralph-enable

# Or with specific task source
ralph-enable --from beads
ralph-enable --from github --label "sprint-1"
ralph-enable --from prd ./docs/requirements.md

# Start autonomous development
ralph --monitor

Option B: Import Existing PRD/Specifications

bash

# Convert existing PRD/specs to Ralph format
ralph-import my-requirements.md my-project
cd my-project

# Review and adjust the generated files:
# - .ralph/PROMPT.md (Ralph instructions)
# - .ralph/fix_plan.md (task priorities)
# - .ralph/specs/requirements.md (technical specs)

# Start autonomous development
ralph --monitor

Option C: Create New Project from Scratch

bash

# Create blank Ralph project
ralph-setup my-awesome-project
cd my-awesome-project

# Configure your project requirements manually
# Edit .ralph/PROMPT.md with your project goals
# Edit .ralph/specs/ with detailed specifications
# Edit .ralph/fix_plan.md with initial priorities

# Start autonomous development
ralph --monitor

Ongoing Usage (After Setup)

Once Ralph is installed and your project is initialized:

bash

# Navigate to any Ralph project and run:
ralph --monitor              # Integrated tmux monitoring (recommended)

# Or use separate terminals:
ralph                        # Terminal 1: Ralph loop
ralph-monitor               # Terminal 2: Live monitor dashboard

Uninstalling Ralph

To completely remove Ralph from your system:

bash

# Run the uninstall script
./uninstall.sh

# Or if you deleted the repo, download and run:
curl -sL https://raw.githubusercontent.com/frankbria/ralph-claude-code/main/uninstall.sh | bash

Understanding Ralph Files

After running ralph-enable or ralph-import, you'll have a .ralph/ directory with several files. Here's what each file does and whether you need to edit it:

File	Auto-Generated?	You Should...
`.ralph/PROMPT.md`	Yes (smart defaults)	Review & customize project goals and principles
`.ralph/fix_plan.md`	Yes (can import tasks)	Add/modify specific implementation tasks
`.ralph/AGENT.md`	Yes (detects build commands)	Rarely edit (auto-maintained by Ralph)
`.ralph/specs/`	Empty directory	Add files when PROMPT.md isn't detailed enough
`.ralph/specs/stdlib/`	Empty directory	Add reusable patterns and conventions
`.ralphrc`	Yes (project-aware)	Rarely edit (sensible defaults)

Key File Relationships

text

PROMPT.md (high-level goals)
    ↓
specs/ (detailed requirements when needed)
    ↓
fix_plan.md (specific tasks Ralph executes)
    ↓
AGENT.md (build/test commands - auto-maintained)

When to Use specs/

Simple projects: PROMPT.md + fix_plan.md is usually enough
Complex features: Add specs/feature-name.md for detailed requirements
Team conventions: Add specs/stdlib/convention-name.md for reusable patterns

See the User Guide for detailed explanations and the examples/ directory for realistic project configurations.

How It Works

Ralph operates on a simple but powerful cycle:

Read Instructions - Loads PROMPT.md with your project requirements
Execute Claude Code - Runs Claude Code with current context and priorities
Track Progress - Updates task lists and logs execution results
Evaluate Completion - Checks for exit conditions and project completion signals
Repeat - Continues until project is complete or limits are reached

Intelligent Exit Detection

Ralph uses a dual-condition check to prevent premature exits during productive iterations:

Exit requires BOTH conditions:

completion_indicators >= 2 (heuristic detection from natural language patterns)
Claude's explicit EXIT_SIGNAL: true in the RALPH_STATUS block

Example behavior:

text

Loop 5: Claude outputs "Phase complete, moving to next feature"
        → completion_indicators: 3 (high confidence from patterns)
        → EXIT_SIGNAL: false (Claude says more work needed)
        → Result: CONTINUE (respects Claude's explicit intent)

Loop 8: Claude outputs "All tasks complete, project ready"
        → completion_indicators: 4
        → EXIT_SIGNAL: true (Claude confirms done)
        → Result: EXIT with "project_complete"

Other exit conditions:

All tasks in .ralph/fix_plan.md marked complete — except unchecked items under optional sections
Multiple consecutive "done" signals from Claude Code
Too many test-focused loops (indicating feature completeness)
Claude API 5-hour usage limit reached (with user prompt to wait or exit)

Optional / Future sections in fix_plan.md

By default, Ralph keeps looping until every - [ ] item is checked. To mark work as
genuinely optional so it does not block completion, put it under an optional section:

markdown

## High Priority
- [x] Core feature

## Optional
- [ ] Frontend integration   # does NOT block exit
- [ ] SMS notifications      # does NOT block exit

Unchecked items under Optional, Future, Future Enhancements, or Nice to Have headings
(and their subsections) are ignored by the completion check. Customize the section names with
OPTIONAL_SECTIONS in .ralphrc (comma-separated, case-insensitive). This resolves the
deadlock where Claude treats low-priority items as skippable while Ralph waits for them.

Enabling Ralph in Existing Projects

The ralph-enable command provides an interactive wizard for adding Ralph to existing projects:

bash

cd my-existing-project
ralph-enable

The wizard:

Detects Environment - Identifies project type (TypeScript, Python, etc.) and framework
Selects Task Sources - Choose from beads, GitHub Issues, or PRD documents
Configures Settings - Set tool permissions and loop parameters
Generates Files - Creates .ralph/ directory and .ralphrc configuration
Verifies Setup - Confirms all files are created correctly

Non-interactive mode for CI/automation:

bash

ralph-enable-ci                              # Sensible defaults
ralph-enable-ci --from github               # Import from GitHub Issues
ralph-enable-ci --project-type typescript   # Override detection
ralph-enable-ci --json                      # Machine-readable output

Importing Existing Requirements

Ralph can convert existing PRDs, specifications, or requirement documents into the proper Ralph format using Claude Code.

Supported Formats

Markdown (.md) - Product requirements, technical specs
Text files (.txt) - Plain text requirements
JSON (.json) - Structured requirement data
Word documents (.docx) - Business requirements
PDFs (.pdf) - Design documents, specifications
Any text-based format - Ralph will intelligently parse the content

Usage Examples

bash

# Convert a markdown PRD
ralph-import product-requirements.md my-app

# Convert a text specification
ralph-import requirements.txt webapp

# Convert a JSON API spec
ralph-import api-spec.json backend-service

# Let Ralph auto-name the project from filename
ralph-import design-doc.pdf

What Gets Generated

Ralph-import creates a complete project with:

.ralph/PROMPT.md - Converted into Ralph development instructions
.ralph/fix_plan.md - Requirements broken down into prioritized tasks
.ralph/specs/requirements.md - Technical specifications extracted from your document
.ralphrc - Project configuration file with tool permissions
Standard Ralph structure - All necessary directories and template files in .ralph/

The conversion is intelligent and preserves your original requirements while making them actionable for autonomous development.

Importing from GitHub Issues

Ralph can also import a development plan directly from a GitHub issue. The issue body and discussion comments are converted into the same Ralph format as a local PRD.

Prerequisites

GitHub CLI (gh) installed: brew install gh or sudo apt install gh (see https://cli.github.com)
Authenticated: gh auth login
jq installed (used to parse issue JSON)

Usage Examples

bash

# Import a specific issue by number
ralph-import --github-issue 42

# Import the oldest open issue matching a search
ralph-import --github-search "fix login timeout"

# Import the oldest open issue with a label
ralph-import --github-label "sprint-1"

# Fetch from a specific repository (default: repo of the current directory)
ralph-import --github-issue 42 --repo myorg/myrepo

# Override the auto-generated project name (slug of the issue title)
ralph-import --github-issue 42 my-project

# Also import issue comments (e.g. when a plan was posted as a comment)
ralph-import --github-issue 42 --include-comments

The issue title becomes the project name (slugified, e.g. Add User Login → add-user-login) and the issue body becomes the PRD content. --github-issue addresses an exact issue and cannot be combined with the filter flags below.

Filtering and Selecting Issues by Metadata

Instead of an exact issue number, issues can be queried by metadata. Filter flags are freely combinable; matches are sorted oldest-first.

bash

# Issues carrying ALL listed labels (comma = AND)
ralph-import --github-label "bug,P0"

# High-priority bugs assigned to me
ralph-import --github-label "bug,P0" --github-assignee @me

# Unassigned issues with a label, skipping anything marked wontfix
ralph-import --github-label "good-first-issue" --github-assignee none --exclude-label wontfix

# Title pattern: * matches anything, everything else is literal (case-insensitive)
ralph-import --github-title "[P0]*"

# Milestone, including closed issues
ralph-import --github-milestone "v1.0" --github-state all

When several issues match, --select picks the winner:

bash

ralph-import --github-label bug --select first        # oldest issue (default)
ralph-import --github-label bug --select interactive  # numbered menu to choose from
ralph-import --github-label bug --select priority     # highest-priority label

The priority strategy understands both bare P0–P9 labels and the priority: P0 form; ties go to the oldest issue, and issues without priority labels fall back to the oldest match. Non-interactive sessions using --select interactive fall back to the oldest match with a warning instead of blocking.

--dry-run previews the matches and what would be selected without importing anything:

bash

ralph-import --github-label bug --dry-run

Security note: issue comments are excluded by default — on public repositories anyone can comment, and comment text flows into the AI conversion prompt. Pass --include-comments only when you trust the discussion (e.g. plans posted by maintainers).

Completeness Assessment and Plan Generation

GitHub issues vary widely in detail. During import, Ralph scores the issue 0–100 for implementation readiness (acceptance criteria, task checklists, code examples, section structure, guidance keywords, length). Issues scoring below the threshold (default: 60) get an implementation plan generated by Claude Code before conversion — the plan is folded into the generated fix_plan.md tasks and preserved verbatim at .ralph/specs/implementation-plan.md.

bash

# Default: assess the issue, generate a plan only if it lacks detail
ralph-import --github-issue 42

# Always generate a plan, with a specific model
ralph-import --github-issue 42 --generate-plan --plan-model opus

# Never generate a plan (fails if the issue scores below the threshold)
ralph-import --github-issue 42 --no-generate-plan

# Tune the threshold and skip the approval prompt (automation/CI)
ralph-import --github-issue 42 --completeness-threshold 75 --auto-approve

Generated plans are shown for approval before conversion. Non-interactive sessions (and --auto-approve) accept the plan automatically, so unattended imports never block on a prompt.

Troubleshooting

"GitHub CLI (gh) is not installed" — install it from https://cli.github.com
"GitHub CLI is not authenticated" — run gh auth login

GitHub Issue Lifecycle

Once development is underway, Ralph can close the loop on the whole GitHub workflow. Pass
--github-issue <ref> (a number 69, #69, owner/repo#69, or a full issue URL) to ralph
and opt into any of the lifecycle actions below. They all use the gh CLI (so the same
gh auth login prerequisite applies), and every GitHub operation degrades gracefully — if a
call is denied, Ralph logs a warning and keeps developing rather than crashing the loop.

bash

# Post a progress comment to the issue every 5 loops while developing
ralph --github-issue 69 --comment-progress --comment-interval 5

# On completion: open a PR linked to the issue, comment a summary, and close it
ralph --github-issue 69 --create-pr --link-issue --close-summary --auto-close

# Add labels when closing, and open a follow-up issue for any TODO/FIXME left in the diff
ralph --github-issue 69 --auto-close --add-label completed \
      --create-followups --followup-label tech-debt

# Open the PR as a draft for manual review before merge
ralph --github-issue 69 --create-pr --draft-pr

Flag	Effect
`--github-issue REF`	Track the issue (required for all lifecycle features)
`--comment-progress`	Post progress comments during development
`--comment-interval N`	Comment every N loops (default: 5)
`--auto-close`	Close the issue on graceful completion
`--close-summary`	Post a completion summary comment
`--create-pr`	Create a pull request on completion
`--link-issue`	Add `Closes #N` to the PR body
`--draft-pr`	Create the PR as a draft
`--create-followups`	Open a grouped follow-up issue for TODO/FIXME markers added during dev
`--followup-label LABEL`	Label for follow-up issues (default: `tech-debt`)
`--add-label LABEL`	Label to add on close (repeatable)

These can also be set in .ralphrc (COMMENT_PROGRESS, AUTO_CLOSE, CREATE_PR, etc.).
Lifecycle state is tracked in .ralph/.github_lifecycle_state.

Batch Processing and Issue Queue

For larger efforts, the ralph-queue command builds a persistent queue of work items (GitHub issues or local PRD specs) and processes them sequentially, respecting priority and dependencies. The queue is stored at .ralph/queue.json and survives restarts, so an interrupted run can be resumed. See docs/QUEUE_MANAGEMENT.md for the full guide.

Building a queue

bash

# Queue issues by metadata filter (reuses the import filter flags)
ralph-queue add --github-label "bug,P0"
ralph-queue add --github-milestone "v1.0"

# Queue specific issues by number
ralph-queue add --github-issues 69,70,71

# Queue a local PRD/spec file
ralph-queue add --prd ./docs/feature.md

When a GitHub issue is queued, its priority is read from P0–P9 / priority: PN labels and its dependencies are parsed from the body (depends on #N, blocked by #N, requires #N).

Managing the queue

bash

ralph-queue status            # Show the queue (counts + items); --json for machine output
ralph-queue next              # Print the id of the next ready item
ralph-queue reorder           # Sort the queue by priority (P0 first)
ralph-queue validate          # Check for circular dependencies
ralph-queue remove 69         # Remove an item by issue number or id
ralph-queue clear             # Empty the queue

These are also available through ralph itself: ralph --queue-status, ralph --queue-next, ralph --queue-clear, and ralph --queue-remove .

Processing the queue

bash

# Process all ready pending items in priority/dependency order
ralph --process-queue
ralph-queue process

# Stop at the first failure instead of skipping it
ralph --process-queue --halt-on-failure

# Resume after an interruption (only pending items are picked up)
ralph --resume-queue

For each ready item the processor stages the project from the issue/spec, runs the Ralph loop, commits the work as Fix #N: <title> (one commit per issue when in a git repo), then advances. Failed items are marked failed and skipped by default (or halt the run with --halt-on-failure); items whose dependencies never complete remain pending. Progress is written to .ralph/logs/queue_processing.log and shown in the ralph-monitor dashboard.

Concurrent (parallel) processing is intentionally out of scope — items are processed one at a time on a single branch.

"Could not fetch issue #N" — check the issue number, your repo access, and the --repo value
"No issues match the specified filters" — relax or remove some filters; only open issues are matched unless --github-state closed|all is given. --dry-run shows what a filter set matches.

Docker Sandbox Execution

Run Claude Code inside an isolated Docker container instead of directly on your machine (Issue #74). Ralph's loop, rate limiting, and monitoring stay on the host; only Claude's execution — the part that edits files and runs commands autonomously — is containerized. The project directory is bind-mounted read-write at /workspace, so changes land on the host directly and ralph-monitor works unchanged.

Setup

bash

# One time: pull the official image (published on release tags)...
docker pull ghcr.io/frankbria/ralph-sandbox:latest
docker tag ghcr.io/frankbria/ralph-sandbox:latest ralph-sandbox:latest

# ...or build it yourself (from a source checkout, or ~/.ralph after install)
docker build -t ralph-sandbox .

Usage

bash

ralph --sandbox docker                          # Default image, 4g RAM, 2 CPUs, bridge network
ralph --sandbox docker --sandbox-image node:20  # Any image with `claude` on PATH
ralph --sandbox docker --sandbox-memory 8g --sandbox-cpus 4
ralph --sandbox docker --sandbox-network none   # Full network isolation (blocks the Claude API —
                                                # only for images with their own auth/proxy setup)
ralph --monitor --sandbox docker                # Works with tmux monitoring

Equivalent .ralphrc settings: SANDBOX_PROVIDER, SANDBOX_DOCKER_IMAGE, SANDBOX_DOCKER_MEMORY, SANDBOX_DOCKER_CPUS, SANDBOX_DOCKER_NETWORK (CLI flags override).

How credentials reach the container

ANTHROPIC_API_KEY set → handed off via a 0600 env-file passed to docker run --env-file (never logged)
Otherwise, your ~/.claude/.credentials.json is copied into a container-scoped directory mounted as the container's home — the container never touches your real ~/.claude
Both are removed by the automatic cleanup on exit (including Ctrl+C)

A persistent container serves all loop iterations (Claude session state survives between loops); it is stopped and removed when the loop exits. If sandbox setup fails, Ralph refuses to fall back to host execution. See docs/DOCKER_SANDBOX.md for details.

E2B Cloud Sandbox Execution

Run Claude Code inside an E2B cloud sandbox instead of on your machine (Issue #75). Like the Docker provider, Ralph's loop, rate limiting, and monitoring stay host-side — but since the cloud has no bind mount, the project is uploaded once at startup and changed files are downloaded back after every iteration.

Setup

bash

pip install e2b                       # official E2B Python SDK (the transport)
export E2B_API_KEY="e2b_..."          # or: store in ~/.ralph/e2b_api_key (chmod 600)

Usage

bash

ralph --sandbox e2b                                   # base template; claude CLI auto-bootstrapped
ralph --sandbox e2b --sandbox-template my-template    # custom template with claude preinstalled
ralph --sandbox e2b --sandbox-timeout 7200            # 2h session timeout (expired sandboxes auto-recreate)
ralph --sandbox e2b --sandbox-max-cost 5.00 --sandbox-cost-alert 2.00   # budget controls
ralph --sandbox e2b --sandbox-keep-alive              # leave it running; reuse with --sandbox-id 
ralph --monitor --sandbox e2b                         # works with tmux monitoring (cost shown in the dashboard)

# Sync filtering (Issue #76): control what uploads/downloads
ralph --sandbox e2b --sync-include "src/**,tests/**,*.md" --sync-exclude "*.log,node_modules"

Equivalent .ralphrc settings: SANDBOX_E2B_TEMPLATE, SANDBOX_E2B_TIMEOUT, SANDBOX_E2B_KEEP_ALIVE, SANDBOX_E2B_MAX_COST, SANDBOX_E2B_COST_ALERT, SANDBOX_E2B_COST_PER_HOUR (CLI flags override; the API key itself never goes in .ralphrc).

Claude auth reaches the sandbox via ANTHROPIC_API_KEY (passed as a sandbox env var) or a copy of your host ~/.claude/.credentials.json. Cost is estimated as cumulative runtime × SANDBOX_E2B_COST_PER_HOUR (cost accrues across sandbox replacements, so --sandbox-max-cost spans the whole run) and surfaced in status.json, the monitor, and .ralph/logs/e2b_cost.log. File sync includes deletion propagation — files removed or renamed in the sandbox are deleted from the host after each iteration. What syncs is filterable: --sync-include/--sync-exclude patterns, a .ralphignore file (gitignore-like subset), and a large-file policy (SYNC_MAX_FILE_SIZE/SYNC_LARGE_FILE_ACTION); upload and download log file-count + size summaries. Note: commits made inside the sandbox are not synced back — changes arrive as uncommitted modifications on the host (.git is excluded from sync in both directions). Docker and E2B are the supported providers; additional providers (Daytona, Cloudflare) are not planned (#79, #80). See docs/E2B_SANDBOX.md and docs/SANDBOX_SYNC.md for details.

Each Ralph project can have a .ralphrc configuration file:

bash

# .ralphrc - Ralph project configuration
PROJECT_NAME="my-project"
PROJECT_TYPE="typescript"

# Claude Code CLI command (auto-detected, override if needed)
CLAUDE_CODE_CMD="claude"
# CLAUDE_CODE_CMD="npx @anthropic-ai/claude-code"  # Alternative: use npx

# Shell init file — source before running claude (useful for zsh/fish users
# whose PATH or env vars are only set in their shell's init file)
#RALPH_SHELL_INIT_FILE="~/.zshrc"

# Loop settings
MAX_CALLS_PER_HOUR=100
CLAUDE_TIMEOUT_MINUTES=15
CLAUDE_OUTPUT_FORMAT="json"
# Token budget per hour (0 = disabled). One Claude call can use 100k+ tokens.
#MAX_TOKENS_PER_HOUR=500000

# Tool permissions
ALLOWED_TOOLS="Write,Read,Edit,Bash(git *),Bash(npm *),Bash(pytest)"

# Session management
SESSION_CONTINUITY=true
SESSION_EXPIRY_HOURS=24

# Circuit breaker thresholds
CB_NO_PROGRESS_THRESHOLD=3
CB_SAME_ERROR_THRESHOLD=5

Rate Limiting & Circuit Breaker

Ralph includes intelligent rate limiting and circuit breaker functionality:

bash

# Default: 100 calls per hour
ralph --calls 50

# With integrated monitoring
ralph --monitor --calls 50

# Check current usage (shows calls and tokens used this hour)
ralph --status

Rate limiting supports two independent limits — both reset hourly:

Setting	Default	Description
`MAX_CALLS_PER_HOUR`	`100`	Max Claude invocations per hour
`MAX_TOKENS_PER_HOUR`	`0` (disabled)	Max cumulative tokens per hour

Token tracking extracts input_tokens + output_tokens from each Claude response. A single call can consume 100k+ tokens, so MAX_TOKENS_PER_HOUR provides cost control that MAX_CALLS_PER_HOUR alone cannot.

The circuit breaker automatically:

Detects API errors and rate limit issues with advanced two-stage filtering
Opens circuit after 3 loops with no progress or 5 loops with same errors
Eliminates false positives from JSON fields containing "error"
Accurately detects stuck loops with multi-line error matching
Gradually recovers with half-open monitoring state
Auto-recovers after cooldown period (default: 30 minutes) — OPEN → HALF_OPEN → CLOSED
Provides detailed error tracking and logging with state history

Auto-recovery options:

bash

# Default: 30-minute cooldown before auto-recovery attempt
CB_COOLDOWN_MINUTES=30     # Set in .ralphrc (0 = immediate)

# Auto-reset on startup (for fully unattended operation)
ralph --auto-reset-circuit
# Or set in .ralphrc: CB_AUTO_RESET=true

Claude API 5-Hour Limit

When Claude's 5-hour usage limit is reached, Ralph:

Detects the limit using three-layer verification (timeout guard → structural JSON → filtered text fallback)
Prompts you to choose:
- Option 1: Wait 60 minutes for the limit to reset (with countdown timer)
- Option 2: Exit gracefully
Unattended mode: Auto-waits on prompt timeout (30s) instead of exiting
Prevents false positives from echoed file content mentioning "5-hour limit"

Custom Prompts

bash

# Use custom prompt file
ralph --prompt my_custom_instructions.md

# With integrated monitoring
ralph --monitor --prompt my_custom_instructions.md

Execution Timeouts

bash

# Set Claude Code execution timeout (default: 15 minutes)
ralph --timeout 30  # 30-minute timeout for complex tasks

# With monitoring and custom timeout
ralph --monitor --timeout 60  # 60-minute timeout

# Short timeout for quick iterations
ralph --verbose --timeout 5  # 5-minute timeout with progress

Verbose Mode

bash

# Enable detailed progress updates during execution
ralph --verbose

# Combine with other options
ralph --monitor --verbose --timeout 30

Live Streaming Output

bash

# Enable real-time visibility into Claude Code execution
ralph --live

# Combine with monitoring for best experience
ralph --monitor --live

# Live output is written to .ralph/live.log
tail -f .ralph/live.log  # Watch in another terminal

Live streaming mode shows Claude Code's output in real-time as it works, providing visibility into what's happening during each loop iteration.

Session Continuity

Ralph maintains session context across loop iterations for improved coherence:

bash

# Sessions are enabled by default with --continue flag
ralph --monitor                 # Uses session continuity

# Start fresh without session context
ralph --no-continue             # Isolated iterations

# Reset session manually (clears context)
ralph --reset-session           # Clears current session

# Check session status
cat .ralph/.ralph_session              # View current session file
cat .ralph/.ralph_session_history      # View session transition history

Session Auto-Reset Triggers:

Circuit breaker opens (stagnation detected)
Manual interrupt (Ctrl+C / SIGINT)
Project completion (graceful exit)
Manual circuit breaker reset (--reset-circuit)
Session expiration (default: 24 hours)

Sessions are persisted to .ralph/.ralph_session with a configurable expiration (default: 24 hours). The last 50 session transitions are logged to .ralph/.ralph_session_history for debugging.

Exit Thresholds

Modify these variables in ~/.ralph/ralph_loop.sh:

Exit Detection Thresholds:

bash

MAX_CONSECUTIVE_TEST_LOOPS=3     # Exit after 3 test-only loops
MAX_CONSECUTIVE_DONE_SIGNALS=2   # Exit after 2 "done" signals
TEST_PERCENTAGE_THRESHOLD=30     # Flag if 30%+ loops are test-only

Circuit Breaker Thresholds:

bash

CB_NO_PROGRESS_THRESHOLD=3       # Open circuit after 3 loops with no file changes
CB_SAME_ERROR_THRESHOLD=5        # Open circuit after 5 loops with repeated errors
CB_OUTPUT_DECLINE_THRESHOLD=70   # Open circuit if output declines by >70%
CB_COOLDOWN_MINUTES=30           # Minutes before OPEN → HALF_OPEN auto-recovery
CB_AUTO_RESET=false              # true = reset to CLOSED on startup (bypasses cooldown)

Completion Indicators with EXIT_SIGNAL Gate:

completion_indicators	EXIT_SIGNAL	Result
>= 2	`true`	Exit ("project_complete")
>= 2	`false`	Continue (Claude still working)
>= 2	missing	Continue (defaults to false)
< 2	`true`	Continue (threshold not met)

Project Structure

Ralph creates a standardized structure for each project with a .ralph/ subfolder for configuration:

text

my-project/
├── .ralph/                 # Ralph configuration and state (hidden folder)
│   ├── PROMPT.md           # Main development instructions for Ralph
│   ├── fix_plan.md        # Prioritized task list
│   ├── AGENT.md           # Build and run instructions
│   ├── specs/              # Project specifications and requirements
│   │   └── stdlib/         # Standard library specifications
│   ├── examples/           # Usage examples and test cases
│   ├── logs/               # Ralph execution logs
│   └── docs/generated/     # Auto-generated documentation
├── .ralphrc                # Ralph configuration file (tool permissions, settings)
└── src/                    # Source code implementation (at project root)

Migration: If you have existing Ralph projects using the old flat structure, run ralph-migrate to automatically move files to the .ralph/ subfolder.

Best Practices

Writing Effective Prompts

Be Specific - Clear requirements lead to better results
Prioritize - Use .ralph/fix_plan.md to guide Ralph's focus
Set Boundaries - Define what's in/out of scope
Include Examples - Show expected inputs/outputs

Project Specifications

Place detailed requirements in .ralph/specs/
Use .ralph/fix_plan.md for prioritized task tracking
Keep .ralph/AGENT.md updated with build instructions
Document key decisions and architecture

Monitoring Progress

Use ralph-monitor for live status updates
Check logs in .ralph/logs/ for detailed execution history
Monitor .ralph/status.json for programmatic access
Watch for exit condition signals

System Requirements

Bash 4.0+ - For script execution
Claude Code CLI - npm install @anthropic-ai/claude-code (or use npx — set CLAUDE_CODE_CMD in .ralphrc)
tmux - Terminal multiplexer for integrated monitoring (recommended)
jq - JSON processing for status tracking
Git - Version control (projects are initialized as git repos)
GNU coreutils - For the timeout command (execution timeouts)
- Linux: Pre-installed on most distributions
- macOS: Install via brew install coreutils (provides gtimeout)
Standard Unix tools - grep, date, etc.

Testing Requirements (Development)

See TESTING.md for the comprehensive testing guide.

If you want to run the test suite:

bash

# Install BATS testing framework
npm install bats bats-support bats-assert

# Run unit + integration tests (771 tests)
npm test

# Run end-to-end tests (13 tests; full ralph_loop.sh subprocess runs)
npm run test:e2e

# Run specific test suites
bats tests/unit/test_rate_limiting.bats
bats tests/unit/test_exit_detection.bats
bats tests/unit/test_json_parsing.bats
bats tests/unit/test_cli_modern.bats
bats tests/unit/test_cli_parsing.bats
bats tests/unit/test_session_continuity.bats
bats tests/unit/test_enable_core.bats
bats tests/unit/test_task_sources.bats
bats tests/unit/test_ralph_enable.bats
bats tests/unit/test_wizard_utils.bats
bats tests/unit/test_circuit_breaker_recovery.bats
bats tests/integration/test_loop_execution.bats
bats tests/integration/test_prd_import.bats
bats tests/integration/test_project_setup.bats
bats tests/integration/test_installation.bats

# Run error detection and circuit breaker tests
./tests/test_error_detection.sh
./tests/test_stuck_loop_detection.sh

Current test status:

784 tests across 34 test files
100% pass rate (784/784 passing)
Comprehensive unit, integration, and end-to-end tests
Specialized tests for JSON parsing, CLI flags, circuit breaker, EXIT_SIGNAL behavior, enable wizard, and installation workflows
True E2E suite running ralph_loop.sh as a subprocess against a mock Claude CLI (tests/e2e/)

Note on Coverage: Bash code coverage measurement with kcov has fundamental limitations when tracing subprocess executions. Test pass rate (100%) is the quality gate. See bats-core#15 for details.

Installing tmux

bash

# Ubuntu/Debian
sudo apt-get install tmux

# macOS
brew install tmux

# CentOS/RHEL
sudo yum install tmux

Installing GNU coreutils (macOS)

Ralph uses the timeout command for execution timeouts. On macOS, you need to install GNU coreutils:

bash

# Install coreutils (provides gtimeout)
brew install coreutils

# Verify installation
gtimeout --version

Ralph automatically detects and uses gtimeout on macOS. No additional configuration is required after installation.

Monitoring and Debugging

Live Dashboard

bash

# Integrated tmux monitoring (recommended)
ralph --monitor

# Manual monitoring in separate terminal
ralph-monitor

Shows real-time:

Current loop count and status
API calls used vs. limit
Recent log entries
Rate limit countdown

tmux Controls:

Ctrl+B then D - Detach from session (keeps Ralph running)
Ctrl+B then ←/→ - Switch between panes
tmux list-sessions - View active sessions
tmux attach -t <session-name> - Reattach to session

Status Checking

bash

# JSON status output
ralph --status

# Manual log inspection
tail -f .ralph/logs/ralph.log

Common Issues

Ralph exits silently on first loop - Claude Code CLI may not be installed or not in PATH. Ralph validates the command at startup and shows installation instructions. If using npx, add CLAUDE_CODE_CMD="npx @anthropic-ai/claude-code" to .ralphrc
Rate Limits - Ralph automatically waits and displays countdown
5-Hour API Limit - Ralph detects and prompts for user action (wait or exit)
Stuck Loops - Check fix_plan.md for unclear or conflicting tasks
Early Exit - Review exit thresholds if Ralph stops too soon
Premature Exit - Check if Claude is setting EXIT_SIGNAL: false (Ralph now respects this)
Execution Timeouts - Increase --timeout value for complex operations
Missing Dependencies - Ensure Claude Code CLI and tmux are installed
tmux Session Lost - Use tmux list-sessions and tmux attach to reconnect
Session Expired - Sessions expire after 24 hours by default; use --reset-session to start fresh
timeout: command not found (macOS) - Install GNU coreutils: brew install coreutils
Permission Denied - Ralph halts when Claude Code is denied permission for commands:
1. Edit .ralphrc and update ALLOWED_TOOLS to include required tools
2. Common patterns: Bash(npm *), Bash(git *), Bash(pytest)
3. Run ralph --reset-session after updating .ralphrc
4. Restart with ralph --monitor

Star History

File: docs/user-guide/01-quick-start.md

Quick Start: Your First Ralph Project

This tutorial walks you through enabling Ralph on an existing project and running your first autonomous development loop. By the end, you'll have Ralph building a simple CLI todo app.

Prerequisites

Ralph installed globally (./install.sh from the ralph-claude-code repo)
Claude Code CLI installed (npm install @anthropic-ai/claude-code)
A project directory (we'll create one)

Step 1: Create Your Project

Let's create a simple Node.js project:

bash

mkdir todo-cli
cd todo-cli
npm init -y
git init

Step 2: Enable Ralph

Run the interactive wizard:

bash

ralph-enable

The wizard will:

Detect your project type (Node.js/TypeScript)
Ask about task sources (you can skip for now)
Create the .ralph/ directory with starter files

You'll see output like:

text

Ralph Enable Wizard
==================

Phase 1: Environment Detection
------------------------------
Detected project type: javascript
Detected package manager: npm
Git repository: yes

Phase 2: Task Source Selection
------------------------------
No task sources selected. You can add tasks manually.

Phase 3: Configuration
------------------------------
Creating .ralph/ directory structure...

Phase 4: File Generation
------------------------------
Created: .ralph/PROMPT.md
Created: .ralph/fix_plan.md
Created: .ralph/AGENT.md
Created: .ralphrc

Ralph is now enabled for this project.

Step 3: Customize Your Requirements

After ralph-enable, you have starter files that need customization. Open .ralph/PROMPT.md and replace the placeholder content:

markdown

# Ralph Development Instructions

## Context
You are Ralph, an autonomous AI development agent building a CLI todo application in Node.js.

## Current Objectives
1. Create a command-line todo app with add, list, complete, and delete commands
2. Store todos in a JSON file (~/.todos.json)
3. Use commander.js for argument parsing
4. Include helpful --help output
5. Write unit tests with Jest

## Key Principles
- Keep the code simple and readable
- Use async/await for file operations
- Provide clear error messages
- Follow Node.js best practices

Step 4: Define Your Tasks

Edit .ralph/fix_plan.md to list specific tasks:

markdown

# Fix Plan - Todo CLI

## Priority 1: Core Structure
- [ ] Set up package.json with dependencies (commander, jest)
- [ ] Create src/index.js entry point with commander setup
- [ ] Create src/storage.js for JSON file operations

## Priority 2: Commands
- [ ] Implement `todo add "task description"` command
- [ ] Implement `todo list` command with status indicators
- [ ] Implement `todo complete ` command
- [ ] Implement `todo delete ` command

## Priority 3: Polish
- [ ] Add --help documentation for all commands
- [ ] Handle edge cases (empty list, invalid IDs)
- [ ] Write unit tests for storage module

Step 5: Start Ralph

Now let Ralph build your project:

bash

ralph --monitor

This opens a tmux session with:

Left pane: Ralph loop output (what Claude is doing)
Right pane: Live monitoring dashboard

What You'll See

Ralph will:

Read your PROMPT.md and fix_plan.md
Start implementing tasks in priority order
Create files, run tests, update fix_plan.md
Continue until all tasks are complete

Monitoring Tips

Ctrl+B, then D - Detach from tmux (Ralph keeps running)
tmux attach -t todo-cli - Reattach to watch progress
ralph --status - Check current loop status

Step 6: Review the Results

When Ralph finishes (or you want to check progress), look at:

bash

# See what files were created
ls -la src/

# Check the updated fix_plan.md
cat .ralph/fix_plan.md

# Run the tests Ralph wrote
npm test

# Try your new CLI
node src/index.js add "Buy groceries"
node src/index.js list

What Just Happened?

Ralph followed this cycle:

Read - Loaded PROMPT.md for context and fix_plan.md for tasks
Implement - Wrote code for the highest priority unchecked task
Test - Ran any tests and fixed failures
Update - Marked completed tasks in fix_plan.md
Repeat - Continued until EXIT_SIGNAL was set

Next Steps

Read Understanding Ralph Files to learn what each file does
Check Writing Effective Requirements for best practices
Explore the examples/ directory for more complex projects

Common Questions

Ralph stopped early - why?

Check .ralph/logs/ for the latest log. Common reasons:

Rate limit reached (waits for reset)
Circuit breaker opened (detected stuck loop)
All tasks marked complete

Ralph keeps running tests without implementing anything

Your fix_plan.md might be too vague. Make tasks specific and actionable:

Bad: "Improve the code"
Good: "Add error handling for missing ~/.todos.json file"

How do I add more features later?

Just add new tasks to .ralph/fix_plan.md and run ralph --monitor again. Ralph will pick up where it left off.

File: docs/user-guide/02-understanding-ralph-files.md

Understanding Ralph Files

After running ralph-enable, ralph-import, or ralph-setup, you'll have a .ralph/ directory with several files. This guide explains what each file does and whether you need to edit it.

File Reference Table

File	Auto-Generated?	Who Writes It	Who Reads It	You Should...
`.ralph/PROMPT.md`	Yes (with smart defaults)	You customize it	Ralph reads every loop	Review and customize project goals
`.ralph/fix_plan.md`	Yes (can import tasks)	You + Ralph updates	Ralph reads and updates	Add/modify specific tasks
`.ralph/AGENT.md`	Yes (detects build commands)	Ralph maintains	Ralph reads for build/test	Rarely edit (auto-maintained)
`.ralph/specs/`	Empty directory created	You add files when needed	Ralph reads for context	Add when PROMPT.md isn't detailed enough
`.ralph/specs/stdlib/`	Empty directory created	You add reusable patterns	Ralph reads for conventions	Add shared patterns and conventions
`.ralphrc`	Yes (project-aware)	Usually leave as-is	Ralph reads at startup	Rarely edit (sensible defaults)
`.ralph/logs/`	Created automatically	Ralph writes logs	You review for debugging	Don't edit (read-only)
`.ralph/status.json`	Created at runtime	Ralph updates	Monitoring tools	Don't edit (read-only)

The Core Files

PROMPT.md - Your Project Vision

Purpose: High-level instructions that Ralph reads at the start of every loop.

What to include:

Project description and goals
Key principles or constraints
Technology stack and frameworks
Quality standards

What NOT to include:

Step-by-step implementation tasks (use fix_plan.md)
Detailed API specifications (use specs/)
Build commands (use AGENT.md)

Example:

markdown

## Context
You are Ralph, building a REST API for a bookstore inventory system.

## Key Principles
- Use FastAPI with async database operations
- Follow REST conventions strictly
- Every endpoint needs tests
- Document all API endpoints with OpenAPI

fix_plan.md - Your Task List

Purpose: Prioritized checklist of tasks Ralph works through.

Key characteristics:

Ralph checks off [x] items as it completes them
Ralph may add new tasks it discovers
You can add, reorder, or remove tasks anytime
More specific tasks = better results

Good task structure:

markdown

## Priority 1: Foundation
- [ ] Create database models for Book and Author
- [ ] Set up SQLAlchemy with async support
- [ ] Create Alembic migration for initial schema

## Priority 2: API Endpoints
- [ ] POST /books - create a new book
- [ ] GET /books - list all books with pagination
- [ ] GET /books/{id} - get single book with author details

Bad task structure:

markdown

- [ ] Make the API work
- [ ] Add features
- [ ] Fix bugs

specs/ - Detailed Specifications

Purpose: When PROMPT.md isn't enough detail for a feature.

When to use specs/:

Complex features needing detailed requirements
API contracts that must be followed exactly
Data models with specific validation rules
External system integrations

When NOT to use specs/:

Simple CRUD operations
Features already well-explained in PROMPT.md
General coding standards (put in PROMPT.md)

Example structure:

text

.ralph/specs/
├── api-contracts.md      # OpenAPI-style endpoint definitions
├── data-models.md        # Entity relationships and validations
└── third-party-auth.md   # OAuth integration requirements

specs/stdlib/ - Standard Library Patterns

Purpose: Reusable patterns and conventions for your project.

What belongs here:

Error handling patterns
Logging conventions
Common utility functions specifications
Testing patterns
Code style decisions

Example:

markdown

# Error Handling Standard

All API errors must return:
{
  "error": {
    "code": "BOOK_NOT_FOUND",
    "message": "No book with ID 123 exists",
    "details": {}
  }
}

Use HTTPException with these codes:
- 400: Validation errors
- 404: Resource not found
- 409: Conflict (duplicate)
- 500: Internal errors (log full trace)

AGENT.md - Build Instructions

Purpose: How to build, test, and run the project.

Who maintains it: Primarily Ralph, as it discovers build commands.

When you might edit:

Setting initial build commands for a complex project
Adding environment setup steps
Documenting deployment commands

.ralphrc - Project Configuration

Purpose: Project-specific Ralph settings.

Default contents (usually fine as-is):

bash

PROJECT_NAME="my-project"
PROJECT_TYPE="typescript"
MAX_CALLS_PER_HOUR=100
ALLOWED_TOOLS="Write,Read,Edit,Bash(git *),Bash(npm *),Bash(pytest)"

When to edit:

Restricting tool permissions for security
Adjusting rate limits
Changing session timeout

File Relationships

text

/* Detailed source-code truncated for AI context efficiency. */

Common Scenarios

Scenario 1: Simple feature addition

Just edit fix_plan.md:

markdown

- [ ] Add a /health endpoint that returns {"status": "ok"}

Scenario 2: Complex feature with specific requirements

Add a spec file first, then tasks:

Create .ralph/specs/search-feature.md:

markdown

# Search Feature Specification

## Requirements
- Full-text search on book titles and descriptions
- Must support:
  - Exact phrase matching: "lord of the rings"
  - Boolean operators: fantasy AND epic
  - Fuzzy matching for typos

Then add to fix_plan.md:

markdown

- [ ] Implement search per specs/search-feature.md

Scenario 3: Establishing team conventions

Add to specs/stdlib/:

markdown

# Logging Conventions

All service methods must log:
- Entry with parameters (DEBUG level)
- Exit with result summary (DEBUG level)
- Errors with full context (ERROR level)

Tips for Success

Start simple - Begin with just PROMPT.md and fix_plan.md. Add specs/ only when needed.
Be specific - Vague requirements produce vague results. "Add user auth" is worse than "Add JWT authentication with /login and /logout endpoints".
Let fix_plan.md evolve - Ralph will add tasks it discovers. Review periodically and reprioritize.
Don't over-specify - If Claude can figure it out from context, you don't need to specify it.
Review logs - When something goes wrong, .ralph/logs/ tells you what Ralph was thinking.

File: docs/user-guide/03-writing-requirements.md

Writing Effective Requirements

Ralph works best when it understands what you want. This guide shows you how to write clear requirements in PROMPT.md, when to use specs/, and how fix_plan.md evolves during development.

Make a good API for managing stuff. Use best practices.
Should be fast and work well.

Problems:

What "stuff"? Too vague.
What are "best practices"? Claude will guess.
"Fast" and "work well" aren't measurable.

Good Example

markdown

# Ralph Development Instructions

## Context
You are Ralph, building a REST API for a pet adoption shelter.
The API manages animals, adopters, and adoption records.

## Technology Stack
- Python 3.11+ with FastAPI
- PostgreSQL with SQLAlchemy (async)
- pytest for testing
- Pydantic for validation

## Key Principles
- RESTful endpoints following standard conventions
- All endpoints require authentication except GET /animals
- Soft delete for all entities (is_deleted flag, not actual deletion)
- Pagination on all list endpoints (default 20, max 100)

## Data Entities
- Animal: name, species, breed, age, status (available/adopted/pending)
- Adopter: name, email, phone, approved (boolean)
- Adoption: animal_id, adopter_id, date, status

## Quality Standards
- Every endpoint needs at least one happy-path test
- Input validation with clear error messages
- OpenAPI documentation for all endpoints

Why this works:

Clear domain (pet adoption shelter)
Specific technology choices
Measurable constraints (pagination limits)
Concrete data model
Defined quality bar

fix_plan.md: Task Writing

The Goldilocks Principle

Tasks should be not too big, not too small.

Too big (Ralph doesn't know where to start):

markdown

- [ ] Build the entire authentication system

Too small (wastes loop iterations):

markdown

- [ ] Create the auth folder
- [ ] Create the auth/__init__.py file
- [ ] Create the auth/routes.py file

Just right (one loop of meaningful work):

markdown

- [ ] Create auth routes with POST /login and POST /logout endpoints
- [ ] Add JWT token generation and validation middleware
- [ ] Create refresh token endpoint POST /auth/refresh

Task Structure Template

markdown

# Fix Plan - [Project Name]

- [ ] [Specific, actionable task]
- [ ] [Another specific task]

## Priority 2: [Core Features]
- [ ] [Feature task]
- [ ] [Feature task]

## Priority 3: [Polish/Nice-to-have]

## Discovered

How fix_plan.md Evolves

Initial state (you write this):

markdown

## Priority 1: Database
- [ ] Set up database models for Animal, Adopter, Adoption

## Priority 2: API
- [ ] Create CRUD endpoints for animals

After Loop 1 (Ralph updates):

markdown

## Priority 1: Database
- [x] Set up database models for Animal, Adopter, Adoption

## Priority 2: API
- [ ] Create CRUD endpoints for animals

## Discovered
- [ ] Add database migration with Alembic
- [ ] Create pytest fixtures for test database

After Loop 3:

markdown

## Priority 1: Database
- [x] Set up database models for Animal, Adopter, Adoption

## Priority 2: API
- [x] Create CRUD endpoints for animals
- [ ] Create CRUD endpoints for adopters

## Discovered
- [x] Add database migration with Alembic
- [x] Create pytest fixtures for test database
- [ ] Add pagination to GET /animals endpoint

Ralph adds tasks it discovers and checks them off as it works. You can:

Reorder tasks by moving them to different priority sections
Delete tasks that are no longer relevant
Add new tasks anytime

When to Use specs/

Use specs/ for complex features

PROMPT.md says:

markdown

Add a matching algorithm that suggests animals to adopters.

This is too vague. Create .ralph/specs/matching-algorithm.md:

markdown

# Animal Matching Algorithm

## Inputs
- Adopter preferences: species, max_age, size_preference
- Available animals list

## Algorithm
1. Filter by species (required match)
2. Score by age preference (0-100 points)
   - Within range: 100 points
   - Within 2 years: 50 points
   - Outside: 0 points
3. Score by size preference (0-50 points)
4. Return top 5 by total score

## Output Format
```json
[
  {"animal_id": 1, "score": 145, "reasons": ["species match", "age within preference"]},
  {"animal_id": 3, "score": 120, "reasons": ["species match"]}
]

Edge Cases

No matches: return empty array
Tie scores: sort by animal.created_at (oldest first)

text

**Then in fix_plan.md**:
```markdown
- [ ] Implement matching algorithm per specs/matching-algorithm.md

Use specs/stdlib/ for conventions

When you want consistency across the project, document it:

.ralph/specs/stdlib/error-responses.md:

markdown

# Error Response Standard

All API errors return this structure:

```json
{
  "error": {
    "code": "ANIMAL_NOT_FOUND",
    "message": "No animal with ID 42 exists",
    "field": null,
    "details": {}
  }
}

Error Codes

Code	HTTP Status	When
VALIDATION_ERROR	400	Invalid input
NOT_FOUND	404	Resource doesn't exist
ALREADY_ADOPTED	409	Animal not available
UNAUTHORIZED	401	Missing/invalid token

text

### Don't use specs/ for everything

**Overkill** - You don't need specs/ for:
```markdown
# User Password Requirements

Passwords must be at least 8 characters.

Just put it in PROMPT.md:

markdown

## Authentication
- Passwords: minimum 8 characters, at least one number
- JWT tokens expire after 1 hour

Common Mistakes

Mistake 1: Assuming Claude knows your preferences

Bad:

markdown

Use standard authentication.

Good:

markdown

Use JWT authentication with 1-hour token expiry.
Refresh tokens last 7 days and rotate on use.

Mistake 2: Mixing implementation with requirements

Bad (in PROMPT.md):

markdown

Create a file called auth.py and add these imports:
import jwt
from datetime import datetime

Good (in PROMPT.md):

markdown

Use JWT for authentication. Tokens should expire after 1 hour.

Let Ralph figure out the implementation details.

Mistake 3: Over-specifying tests

Bad:

markdown

- [ ] Write test_create_animal_success
- [ ] Write test_create_animal_invalid_species
- [ ] Write test_create_animal_missing_name
- [ ] Write test_create_animal_negative_age

Good:

markdown

- [ ] Write tests for animal creation (success and validation errors)

Ralph knows how to write tests. Tell it what to test, not how.

Mistake 4: Forgetting the "why"

Bad:

markdown

Add a 100ms delay to all API responses.

Good:

markdown

Add a 100ms delay to all API responses (required for rate limiting compliance with external payment API).

When Ralph understands why, it makes better decisions.

Checklist: Before Running Ralph

Before ralph --monitor, verify:

PROMPT.md has clear context - Does Ralph know what it's building?
Technology stack is specified - Did you pick the frameworks?
Key constraints are documented - Auth approach? API conventions?
fix_plan.md has specific tasks - Can Ralph start on task 1 immediately?
Complex features have specs/ - Is anything too vague for PROMPT.md?

If you can answer "yes" to these, Ralph will do good work.

Priority 3 Issues - Minor

Missing dedicated test for `--allowed-tools` validation

Location: tests/unit/test_cli_parsing.bats
Severity: Minor
Category: Test Coverage

Problem:
The --allowed-tools flag is tested in the "All flags combined" test (line 276) but lacks a dedicated test for its validation behavior. The implementation in ralph_loop.sh:976-981 calls validate_allowed_tools() which should be tested independently.

Recommendation:
Add a dedicated test for --allowed-tools validation to match the pattern used for other validated flags like --timeout and --output-format.

Suggested Approach:

bash

@test "--allowed-tools flag accepts valid tool list" {
    run bash "$RALPH_SCRIPT" --allowed-tools "Write,Read,Bash" --help

    assert_success
    [[ "$output" == *"Usage:"* ]]
}

Note: This is low priority since the flag is covered in combination tests and the validation function may have its own tests elsewhere.

Positive Findings

Excellent Practices

Comprehensive Flag Coverage: All 12 CLI flags are tested including both long and short forms
Boundary Testing: The --timeout test validates edge cases (0, 1, 120, 121, -5, "abc")
Clear Organization: Well-structured sections with descriptive headers make tests easy to navigate
Early Exit Pattern: Clever use of --help as escape hatch to test flag parsing without triggering main loop

Good Architectural Decisions

Test Isolation: Each test creates its own temp directory with proper cleanup in teardown
Minimal Stubs: Only creates stub libraries actually needed by CLI parsing, not the entire system
Git Initialization: Proper setup of git repo required by some flags

Testing Wins

Short Flag Equivalence: Bonus tests verify -c, -p, -s, -m, -v, -t work identically to long forms
Multiple Flag Combinations: Tests verify flags work together and are order-independent
Error Message Validation: Tests check for specific error messages, not just failure status

Team Collaboration Needed

Handoffs to Other Agents

Architecture Agent:

No issues identified

UX Designer Agent:

Not applicable for CLI tests

DevOps Agent:

Tests integrate well with existing CI/CD via bats tests/unit/

Future Considerations

Patterns for Project Evolution

If new CLI flags are added, this test file provides a clear template
Consider extracting flag validation functions for easier unit testing

Technical Debt Items

Minor: Could add --allowed-tools dedicated test (non-blocking)

Compliance & Best Practices

Testing Standards Met

✅ BATS framework used consistently
✅ Setup/teardown isolation pattern
✅ Clear test naming conventions
✅ Both positive and negative test cases
✅ Boundary value testing

Enterprise Best Practices

Test file follows project conventions from test_helper.bash
Uses fixtures helper for consistency
Proper temp directory cleanup prevents resource leaks

Action Items Summary

Immediate (Before Production)

None - code is ready for merge

Short-term (Next Sprint)

Consider adding dedicated --allowed-tools validation test (optional)

Long-term (Backlog)

None identified

Conclusion

The CLI parsing test file is production-ready with excellent coverage of all CLI flags. The test design is sound, using the --help escape hatch pattern to validate argument parsing without triggering the main execution loop. Tests are well-isolated with proper resource cleanup.

Recommendation: Approve for merge. The one minor issue (missing dedicated --allowed-tools test) is non-blocking since the flag is tested in combination with other flags.

Code Review Report: Phase 1.1 Modern CLI Commands

Ready for Production: ⚠️ Yes, with Recommended Improvements
Branch: feature/phase-1.1-modern-cli-commands
Critical Issues: 0
Major Issues: 3
Minor Issues: 5

Executive Summary

The Phase 1.1 implementation adds JSON output parsing and modern CLI integration to Ralph. The implementation demonstrates good engineering practices with comprehensive test coverage (43 new tests, 100% pass rate) and backward compatibility. However, there are security vulnerabilities and reliability concerns that should be addressed before production deployment.

Overall Quality: 7/10

✅ Excellent test coverage
✅ Backward compatibility maintained
✅ Clean modular architecture
⚠️ Command injection vulnerabilities
⚠️ Insufficient input validation
⚠️ Error handling gaps

Priority 1 (Critical Security Issues) ⛔

None Found

No critical security vulnerabilities that would prevent production deployment. However, see Major Issues below for important security improvements.

Priority 2 (Major Issues - Should Fix Before Production) 🔴

MAJOR-01: Command Injection Vulnerability in `build_claude_command()`

Location: ralph_loop.sh:411-450

Issue: User-controlled input in loop_context is escaped with simple sed before being injected into shell command string. This is insufficient for preventing command injection.

Vulnerable Code:

bash

# Add loop context as system prompt
if [[ -n "$loop_context" ]]; then
    # Escape quotes in context for shell
    local escaped_context=$(echo "$loop_context" | sed 's/"/\\"/g')
    cmd+=" --append-system-prompt \"$escaped_context\""
fi

Attack Vector:
If fix_plan.md or .response_analysis contains malicious content like:

text

"; rm -rf /; echo "

The sed only escapes quotes, but the command is later executed via bash -c "$claude_cmd", allowing command injection through shell metacharacters.

Security Impact: HIGH - Arbitrary command execution

Recommended Fix:

bash

# SECURE: Use printf %q for shell escaping or avoid bash -c entirely
build_claude_command() {
    local prompt_file=$1
    local loop_context=$2
    local session_id=$3

    # Build command as array to avoid injection
    local cmd_array=("$CLAUDE_CODE_CMD")

    if [[ "$CLAUDE_OUTPUT_FORMAT" == "json" ]]; then
        cmd_array+=("--output-format" "json")
    fi

    if [[ -n "$CLAUDE_ALLOWED_TOOLS" ]]; then
        IFS=',' read -ra tools_array <<< "$CLAUDE_ALLOWED_TOOLS"
        cmd_array+=("--allowedTools")
        cmd_array+=("${tools_array[@]}")
    fi

    if [[ "$CLAUDE_USE_CONTINUE" == "true" ]]; then
        cmd_array+=("--continue")
    fi

    if [[ -n "$loop_context" ]]; then
        # No escaping needed - pass as array element
        cmd_array+=("--append-system-prompt" "$loop_context")
    fi

    cmd_array+=("--prompt-file" "$prompt_file")

    # Return array representation or execute directly
    printf '%q ' "${cmd_array[@]}"
}

Alternative Fix (Preferred):
Execute command directly without bash -c:

bash

# In execute_claude_code():
if [[ "$use_modern_cli" == "true" ]]; then
    # Build command array
    local cmd_array
    IFS=' ' read -ra cmd_array <<< "$(build_claude_command_array "$PROMPT_FILE" "$loop_context" "$session_id")"

    # Execute directly (no bash -c)
    if timeout ${timeout_seconds}s "${cmd_array[@]}" > "$output_file" 2>&1 &
    then
        :  # Continue
    fi
fi

MAJOR-02: Input Validation Missing for `CLAUDE_ALLOWED_TOOLS`

Location: ralph_loop.sh:26 (configuration) and build_claude_command() at line 424-432

Issue: The CLAUDE_ALLOWED_TOOLS variable accepts arbitrary comma-separated input without validation. Malicious tool specifications could bypass security restrictions.

Attack Vector:

bash

ralph --allowed-tools "Write,Bash(*),Read"  # Allows ALL bash commands
ralph --allowed-tools "Bash(rm -rf /),Write"  # Potentially dangerous

Security Impact: MEDIUM-HIGH - Tool permission bypass

Recommended Fix:

bash

# Add validation function
validate_allowed_tools() {
    local tools_input=$1
    local allowed_patterns=("Write" "Read" "Edit" "Bash\(git \*\)" "Bash\(npm \*\)" "Bash\(pytest\)")

    IFS=',' read -ra tools_array <<< "$tools_input"
    for tool in "${tools_array[@]}"; do
        local valid=false
        for pattern in "${allowed_patterns[@]}"; do
            if [[ "$tool" =~ ^${pattern}$ ]]; then
                valid=true
                break
            fi
        done

        if [[ "$valid" != "true" ]]; then
            echo "ERROR: Invalid tool specification: $tool" >&2
            echo "Allowed tools: ${allowed_patterns[*]}" >&2
            return 1
        fi
    done

    return 0
}

# Use in argument parsing
--allowed-tools)
    CLAUDE_ALLOWED_TOOLS=$2
    if ! validate_allowed_tools "$CLAUDE_ALLOWED_TOOLS"; then
        exit 1
    fi
    shift 2
    ;;

MAJOR-03: No Rate Limiting for Session Persistence

Location: ralph_loop.sh:382-408 (init_claude_session() and save_claude_session())

Issue: Session IDs are persisted without expiration or validation. Old session IDs could be reused indefinitely, potentially causing:

Context pollution from ancient sessions
API errors if Claude invalidates old sessions
Unexpected behavior when resuming month-old sessions

Reliability Impact: MEDIUM - Unpredictable behavior with stale sessions

Recommended Fix:

bash

# Add session expiration (24 hours)
CLAUDE_SESSION_MAX_AGE=$((24 * 3600))  # 24 hours in seconds

init_claude_session() {
    if [[ -f "$CLAUDE_SESSION_FILE" ]]; then
        local session_age=$(($(date +%s) - $(stat -c %Y "$CLAUDE_SESSION_FILE" 2>/dev/null || echo 0)))

        if [[ $session_age -gt $CLAUDE_SESSION_MAX_AGE ]]; then
            log_status "INFO" "Session expired (${session_age}s old), starting fresh"
            rm -f "$CLAUDE_SESSION_FILE"
        else
            local session_id=$(cat "$CLAUDE_SESSION_FILE" 2>/dev/null)
            if [[ -n "$session_id" ]]; then
                log_status "INFO" "Resuming Claude session: ${session_id:0:20}... (${session_age}s old)"
                echo "$session_id"
                return 0
            fi
        fi
    fi

    log_status "INFO" "Starting new Claude session"
    echo ""
}

Priority 3 (Minor Issues - Technical Debt & Improvements) 🟡

MINOR-01: JSON Parsing Uses Intermediate File

Location: lib/response_analyzer.sh:55-135 (parse_json_response())

Issue: Creates temporary .json_parse_result file instead of using stdout/return values. This adds I/O overhead and leaves cleanup to caller.

Code Quality Impact: LOW - Unnecessary file I/O

Recommended Improvement:

bash

# Return JSON via stdout instead of file
parse_json_response() {
    local output_file=$1

    if [[ ! -f "$output_file" ]] || ! jq empty "$output_file" 2>/dev/null; then
        return 1
    fi

    # Extract and normalize in one jq invocation (more efficient)
    jq -r '{
        status: (.status // "UNKNOWN"),
        exit_signal: ((.exit_signal // false) or (.status == "COMPLETE")),
        is_test_only: ((.work_type // "UNKNOWN") == "TEST_ONLY"),
        is_stuck: ((.error_count // 0) > 5),
        has_completion_signal: ((.status == "COMPLETE") or (.exit_signal == true)),
        files_modified: (.files_modified // 0),
        error_count: (.error_count // 0),
        summary: (.summary // ""),
        loop_number: (.metadata.loop_number // .loop_number // 0),
        session_id: (.metadata.session_id // ""),
        confidence: (.confidence // 0),
        metadata: {
            loop_number: (.metadata.loop_number // .loop_number // 0),
            session_id: (.metadata.session_id // "")
        }
    }' "$output_file"
}

# Usage in analyze_response():
if [[ "$output_format" == "json" ]]; then
    local json_result=$(parse_json_response "$output_file")
    if [[ -n "$json_result" ]]; then
        has_completion_signal=$(echo "$json_result" | jq -r '.has_completion_signal')
        # ... extract other fields
    fi
fi

MINOR-02: Error Messages Leak Sensitive Information

Location: lib/response_analyzer.sh:60-68

Issue: Error messages expose full file paths that could leak directory structure.

Security Impact: LOW - Information disclosure

Example:

bash

echo "ERROR: Output file not found: $output_file" >&2
# Leaks: ERROR: Output file not found: /home/user/secret-project/logs/output.log

Recommended Fix:

bash

echo "ERROR: Output file not found: $(basename "$output_file")" >&2
# Shows: ERROR: Output file not found: output.log

MINOR-03: No Timeout for `jq` Operations

Location: Multiple locations using jq

Issue: Large JSON files could cause jq to hang indefinitely. While unlikely in Ralph's context, defensive programming suggests timeouts.

Reliability Impact: LOW - Potential hang on malformed/huge JSON

Recommended Improvement:

bash

# Wrapper function with timeout
jq_safe() {
    timeout 5s jq "$@"
}

# Use throughout codebase
local status=$(jq_safe -r '.status // "UNKNOWN"' "$output_file" 2>/dev/null)

MINOR-04: Version Comparison Doesn't Handle Pre-release Versions

Location: ralph_loop.sh:318-344 (check_claude_version())

Issue: Version parsing assumes semver format X.Y.Z but doesn't handle pre-release versions like 2.0.76-beta.1.

Example Failure:

bash

version="2.0.76-beta.1"
ver_parts=(${version//./ })  # Results in: (2 0 "76-beta" 1)
ver_num=$((${ver_parts[2]:-0}))  # Attempts arithmetic on "76-beta" -> error

Recommended Fix:

bash

check_claude_version() {
    local version=$($CLAUDE_CODE_CMD --version 2>/dev/null | grep -oE '[0-9]+\.[0-9]+\.[0-9]+' | head -1)

    if [[ -z "$version" ]]; then
        log_status "WARN" "Cannot detect Claude CLI version, assuming compatible"
        return 0
    fi

    # Strip pre-release suffix if present (e.g., "2.0.76-beta.1" -> "2.0.76")
    version=$(echo "$version" | sed 's/-.*$//')

    local required="$CLAUDE_MIN_VERSION"
    local ver_parts=(${version//./ })
    local req_parts=(${required//./ })

    # Add validation
    if [[ ${#ver_parts[@]} -lt 3 ]]; then
        log_status "WARN" "Invalid version format: $version"
        return 0
    fi

    local ver_num=$((${ver_parts[0]:-0} * 10000 + ${ver_parts[1]:-0} * 100 + ${ver_parts[2]:-0}))
    local req_num=$((${req_parts[0]:-0} * 10000 + ${req_parts[1]:-0} * 100 + ${req_parts[2]:-0}))

    if [[ $ver_num -lt $req_num ]]; then
        log_status "WARN" "Claude CLI version $version < $required. Some modern features may not work."
        log_status "WARN" "Consider upgrading: npm update -g @anthropic-ai/claude-code"
        return 1
    fi

    log_status "INFO" "Claude CLI version $version (>= $required) - modern features enabled"
    return 0
}

MINOR-05: Insufficient Logging for Security Events

Location: Throughout ralph_loop.sh and lib/response_analyzer.sh

Issue: Security-relevant events (session changes, tool permission changes, version mismatches) are logged but not aggregated or easily auditable.

Best Practice: Security events should be logged to a separate audit log with structured format for analysis.

Recommended Improvement:

bash

# Add security audit logging
SECURITY_AUDIT_LOG="logs/security_audit.log"

log_security_event() {
    local event_type=$1
    local event_data=$2

    local timestamp=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
    local audit_entry=$(jq -n \
        --arg ts "$timestamp" \
        --arg type "$event_type" \
        --arg data "$event_data" \
        '{timestamp: $ts, event_type: $type, data: $data}'
    )

    echo "$audit_entry" >> "$SECURITY_AUDIT_LOG"
}

# Use throughout codebase
save_claude_session() {
    local output_file=$1

    if [[ -f "$output_file" ]]; then
        local session_id=$(jq -r '.metadata.session_id // .session_id // empty' "$output_file" 2>/dev/null)
        if [[ -n "$session_id" && "$session_id" != "null" ]]; then
            echo "$session_id" > "$CLAUDE_SESSION_FILE"
            log_status "INFO" "Saved Claude session: ${session_id:0:20}..."
            log_security_event "session_change" "New session: ${session_id}"  # ADDED
        fi
    fi
}

Test Coverage Assessment ✅

Excellent Coverage: 43 new tests covering JSON parsing and CLI features

✅ 20/20 JSON parsing tests passing
✅ 23/23 CLI modern tests passing
✅ 100% pass rate maintained
✅ Edge cases covered (malformed JSON, missing files, version mismatches)

Test Quality: HIGH

Tests use proper fixtures and setup/teardown
Both positive and negative test cases
Integration tests verify end-to-end behavior

Coverage Gaps (not critical, but recommended):

No tests for command injection vulnerability (MAJOR-01)
No tests for stale session expiration (MAJOR-03)
No performance tests for large JSON files (MINOR-03)

Recommended Additional Tests:

bash

@test "build_claude_command escapes malicious input in loop_context" {
    # Test command injection protection
    local malicious_context='"; rm -rf /; echo "'

    run build_claude_command "PROMPT.md" "$malicious_context" ""

    # Command should be properly escaped
    [[ "$output" != *"rm -rf"* ]]
}

@test "init_claude_session expires old sessions" {
    echo "old-session-id" > "$CLAUDE_SESSION_FILE"
    # Set file timestamp to 48 hours ago
    touch -d "2 days ago" "$CLAUDE_SESSION_FILE"

    run init_claude_session

    # Should not resume old session
    [[ "$output" == *"new"* ]] || [[ "$output" == *"expired"* ]]
}

Backward Compatibility Assessment ✅

Excellent Backward Compatibility: Implementation maintains full compatibility with existing Ralph deployments.

✅ Fallback to Text Parsing: JSON parsing failures gracefully fall back to original text analysis
✅ Legacy CLI Mode: Users can disable JSON output with --output-format text
✅ Session Opt-out: --no-continue flag preserves original stateless behavior
✅ Default Behavior: All modern features default to sensible values that maintain existing behavior

No Breaking Changes Detected

Performance Considerations 🚀

Potential Performance Issues

Multiple jq Invocations (MINOR)
- parse_json_response() uses 11 separate jq calls
- Could be consolidated into single invocation (see MINOR-01)
- Impact: Negligible for Ralph's use case (small JSON files)
Session File I/O on Every Loop (MINOR)
- init_claude_session() reads file on every loop iteration
- Impact: Negligible (single file read)
Loop Context Regeneration (MINOR)
- build_loop_context() rebuilds context from files on every loop
- Impact: Negligible for typical usage

Recommendation: No performance optimizations required for current scale. Monitor if Ralph is used for high-frequency loops (>1000 iterations).

🔴 CRITICAL ISSUES

Issue 1: Missing Feedback Loop Architecture

MARTIN FOWLER - Architecture Analysis:

text

❌ VIOLATION: Single Responsibility Principle

The execute_claude_code() function has TWO responsibilities:
1. Execute Claude Code (✅ implemented)
2. Analyze results (❌ missing)

Current architecture:
  execute() → log success/failure → return

Required architecture:
  execute() → analyze_output() → update_signals() → determine_next_action() → return

This is a fundamental architectural flaw. The system is deaf - it can speak
(send prompts) but cannot hear (analyze responses). This violates the basic
feedback loop pattern essential for autonomous systems.

RECOMMENDATION:
Extract a ResponseAnalyzer class/module with clear responsibilities:
- Parse Claude Code output
- Detect completion signals
- Identify test-only loops
- Track progress indicators
- Update .exit_signals file

PRIORITY: 🔴 CRITICAL - System cannot function correctly without this
EFFORT: High (requires new component + integration)
IMPACT: Fixes root cause of infinite loops

MICHAEL NYGARD - Production Resilience:

text

❌ CRITICAL: No Circuit Breaker for Unproductive Loops

In "Release It!", I describe the Circuit Breaker pattern for preventing
cascading failures. Ralph needs this for preventing runaway token consumption.

Current state: No failure detection → infinite retry
Required state: Detect stagnation → open circuit → halt execution

Ralph is missing ALL three states:
- CLOSED: Normal operation with progress tracking
- OPEN: Detected stagnation, stop execution, alert user
- HALF-OPEN: Test if progress has resumed after intervention

Specific missing mechanisms:
1. Progress metrics (did files change? did git commit occur?)
2. Stagnation detection (3 loops with no file changes)
3. Automatic halt with clear error message
4. User notification when circuit opens

Real-world scenario:
Loop 1-10: Normal (CLOSED state, progress detected)
Loop 11-13: No file changes detected (transition to HALF-OPEN)
Loop 14: Still no progress (transition to OPEN, halt execution)
Output: "⚠️  Circuit breaker opened: No progress detected in 4 loops.
         Last file change: loop #10. Please review fix_plan.md."

RECOMMENDATION:
Implement Circuit Breaker with these triggers:
- 3 consecutive loops with no git changes → OPEN
- 5 consecutive loops with identical output → OPEN
- Output length declining 50%+ → HALF-OPEN (monitor)
- Token consumption >10K with no file changes → OPEN

PRIORITY: 🔴 CRITICAL - Prevents resource waste
EFFORT: Medium (pattern is well-established)
IMPACT: Saves thousands of wasted tokens, provides clear failure signal

SAM NEWMAN - Service Integration:

text

❌ MISSING: Contract Definition Between Ralph and Claude

In microservices, we define explicit contracts between services. Ralph and
Claude Code are two services that need a well-defined interface contract.

Current state: Implicit, undefined contract
- Ralph sends: PROMPT.md (unstructured)
- Claude returns: Free-form text (unparseable)
- No schema, no validation, no structured data

Required state: Explicit contract with structured I/O

Proposed Contract:
┌─────────────────────────────────────────────────┐
│ RALPH → CLAUDE (Request)                        │
├─────────────────────────────────────────────────┤
│ - task_description: string                      │
│ - loop_number: integer                          │
│ - previous_loops_summary: string                │
│ - exit_signal_request: boolean                  │
└─────────────────────────────────────────────────┘

┌─────────────────────────────────────────────────┐
│ CLAUDE → RALPH (Response)                       │
├─────────────────────────────────────────────────┤
│ - work_performed: string                        │
│ - files_modified: array[string]                 │
│ - completion_status: enum(in_progress|done)     │
│ - confidence_level: float(0-1)                  │
│ - next_recommended_action: string               │
│ - exit_signal: boolean                          │
└─────────────────────────────────────────────────┘

With structured output, Ralph can PARSE the response:
```bash
response=$(parse_claude_response "$output_file")
completion=$(echo "$response" | jq -r '.completion_status')
exit_signal=$(echo "$response" | jq -r '.exit_signal')

if [[ "$exit_signal" == "true" ]]; then
    log_status "SUCCESS" "Claude signaled completion"
    exit 0
fi

RECOMMENDATION:

Define JSON schema for Claude's responses
Update PROMPT.md to request structured output
Add response parser in execute_claude_code()
Validate responses against schema
Log validation failures for debugging

PRIORITY: 🔴 CRITICAL - Enables all other improvements
EFFORT: Medium (schema design + parser implementation)
IMPACT: Makes Ralph's outputs parseable and actionable

## 🟡 HIGH SEVERITY ISSUES

### Issue 2: Weak Requirements Specification

**KARL WIEGERS** - Requirements Quality:

⚠️ MAJOR: Non-Testable Completion Requirements

From PROMPT.md lines 38-45:
"If you believe the project is complete or nearly complete:

Update fix_plan.md to reflect completion status"

This requirement violates SMART criteria:

Specific: ❌ "believe" is subjective
Measurable: ❌ No metric for "complete"
Achievable: ⚠️ Requires manual action
Relevant: ✅ Yes
Timely: ❌ No timeframe

Better requirement:
"When all tasks in fix_plan.md are marked [x] AND no errors are present
in the last test run AND you have nothing left to implement from specs/:

Output: EXIT_SIGNAL=true
Update fix_plan.md with completion summary
List any deferred items in ## Deferred section"

This is:

Specific: Three clear conditions
Measurable: Boolean checks
Achievable: Automated detection possible
Relevant: Directly addresses exit detection
Timely: Occurs when conditions are met

RECOMMENDATION:
Rewrite completion requirements with:

Clear exit conditions (3 measurable criteria)
Structured output format (JSON or key=value)
Validation checklist Claude must verify
Explicit "DONE" signal in parseable format

Example structured output requirement:

text

When ready to exit, output this exact format:
---RALPH_STATUS---
STATUS: COMPLETE
TASKS_COMPLETED: 15/15
TESTS_PASSING: 100%
FILES_CHANGED_THIS_LOOP: 0
RECOMMENDATION: Exit loop, project complete
EXIT_SIGNAL: true
---END_RALPH_STATUS---

PRIORITY: 🟡 HIGH - Required for automated exit detection
EFFORT: Low (documentation update)
IMPACT: Provides clear contract for completion

text

**GOJKO ADZIC** - Specification by Example:

⚠️ MISSING: Concrete Examples of Exit Scenarios

The PROMPT.md tells Claude WHAT to do but not HOW. Let's use Given/When/Then
to make this concrete.

Current state: Abstract instructions
Required state: Concrete examples

Example 1: Successful Completion
Given: All fix_plan.md items are checked [x]
And: Last test run shows 100% passing
And: No errors in logs/
When: Claude evaluates project status
Then: Claude outputs EXIT_SIGNAL=true
And: Provides completion summary
And: Ralph detects signal and exits loop

Example 2: Detected Test-Only Loop
Given: Last 3 loops only executed tests
And: No files were modified
And: No new test files were created
When: Claude starts loop iteration
Then: Claude outputs TEST_ONLY=true
And: Ralph increments test_only_loops counter
And: After 3 consecutive, Ralph exits with "test_saturation"

Example 3: Stuck on Error
Given: Same error appears in last 5 loops
And: No progress on fixing the error
When: Claude attempts same fix repeatedly
Then: Claude outputs STUCK=true
And: Provides error description
And: Recommends human intervention
And: Ralph exits with "needs_human_help"

RECOMMENDATION:
Add "## Exit Scenarios" section to PROMPT.md with 5-10 concrete examples.
Each example should show:

Initial state
Expected detection
Required output format
Ralph's expected action

This makes the contract explicit and testable.

PRIORITY: 🟡 HIGH - Clarity prevents misunderstandings
EFFORT: Low (documentation)
IMPACT: Claude understands exactly what Ralph needs

## 🟠 MEDIUM SEVERITY ISSUES

### Issue 3: Insufficient Testing Coverage

**LISA CRISPIN** - Testing Strategy:

⚠️ TESTING GAP: No Integration Tests for Loop Logic

Current test coverage:
✅ Unit tests: can_make_call(), increment_call_counter() (15 tests)
✅ Unit tests: should_exit_gracefully() (20 tests)
❌ Integration tests: execute_claude_code() + analysis pipeline (0 tests)
❌ E2E tests: Full loop with mock Claude (0 tests)
❌ Performance tests: Token consumption tracking (0 tests)

The CRITICAL gap: No tests for the main loop execution path!

Required test scenarios:

Loop with successful completion
- Mock Claude output with EXIT_SIGNAL=true
- Verify Ralph detects signal and exits
- Verify exit_reason="completion_signals"
Loop with test saturation
- Mock 4 consecutive outputs with only "npm test"
- Verify test_only_loops array populates
- Verify exit_reason="test_saturation"
Loop with no progress
- Mock 3 outputs with no file changes
- Verify circuit breaker opens
- Verify exit_reason="no_progress"
Loop with rate limit
- Mock 100 successful calls
- Verify wait_for_reset() is called
- Verify loop resumes after reset
Loop with API 5-hour limit
- Mock Claude output with rate limit error
- Verify user prompt appears
- Verify loop exits or waits based on user choice

RECOMMENDATION:
Create tests/integration/test_loop_execution.bats with:

Mock Claude Code that returns pre-defined responses
Verification of signal detection and updates
Validation of exit conditions triggering correctly
Token consumption and efficiency metrics

PRIORITY: 🟠 MEDIUM - Required for safe refactoring
EFFORT: High (complex integration tests)
IMPACT: Ensures fixes don't break existing behavior

text

**JANET GREGORY** - Quality Conversations:

⚠️ COLLABORATION GAP: No "Three Amigos" for Exit Detection

The exit detection logic was implemented without involving:

Developer (you) ✅
Tester (who would ask "how do we test this?") ❌
Product owner (who would ask "what's the business value?") ❌

If a tester had been involved, they would have asked:
"How do we verify that exit detection works?"
"What are the edge cases?"
"Can we simulate Claude saying 'done'?"

This would have revealed the missing test coverage and the fact that
.exit_signals is never populated.

If a product owner had been involved, they would have asked:
"What's the cost of getting this wrong?"
"How much will infinite loops cost in tokens?"
"What's our SLA for detecting completion?"

This would have prioritized the feedback loop implementation.

RECOMMENDATION:
For remaining work (response analysis, circuit breaker), conduct
specification workshops with:

Developer: How to implement
Tester: How to verify
User: What's the expected behavior

Document the conversation in specs/ before implementing.

PRIORITY: 🟠 MEDIUM - Process improvement
EFFORT: Low (better planning)
IMPACT: Better requirements, fewer bugs

## 🟢 OPERATIONAL RECOMMENDATIONS

### Issue 4: Missing Observability

**KELSEY HIGHTOWER** - Operational Excellence:

/* Detailed source-code truncated for AI context efficiency. */

text

**MICHAEL NYGARD** - Operational Monitoring:

💡 ENHANCEMENT: Add Health Checks and Status Endpoints

Production systems need health checks. Ralph should too.

Proposed health check (ralph --health):
{
"status": "healthy",
"loop_count": 42,
"last_progress": "2 loops ago",
"circuit_breaker": "closed",
"efficiency": "85%",
"estimated_completion": "10 loops",
"issues": []
}

When unhealthy:
{
"status": "degraded",
"loop_count": 55,
"last_progress": "12 loops ago",
"circuit_breaker": "half-open",
"efficiency": "35%",
"estimated_completion": "unknown",
"issues": [
"No file changes in 12 loops",
"Efficiency below 50%",
"Test saturation detected"
]
}

This enables:

Monitoring from CI/CD systems
Integration with alerting tools
Health-based auto-restart
Status dashboards

RECOMMENDATION:
Add ralph --health command that outputs JSON health status.
Include in ralph-monitor dashboard.
Document for CI/CD integration.

PRIORITY: 🟢 LOW - Operational improvement
EFFORT: Low (status aggregation)
IMPACT: Better monitoring and integration

---

## Implementation Details

### 1. Response Analysis Pipeline ✅
**File**: `lib/response_analyzer.sh` (286 lines)
**Expert Recommendation**: Martin Fowler (Architecture)

**Features Implemented**:
- ✅ Parse structured RALPH_STATUS output (JSON-like format)
- ✅ Detect natural language completion keywords
- ✅ Identify test-only loops (no implementation work)
- ✅ Track file changes via git integration
- ✅ Calculate confidence scores (0-100+)
- ✅ Detect "nothing to do" patterns
- ✅ Analyze output length trends
- ✅ Update .exit_signals file with structured data

**Functions**:
- `analyze_response()` - Main analysis engine
- `update_exit_signals()` - Updates tracking file
- `log_analysis_summary()` - Human-readable output
- `detect_stuck_loop()` - Repetitive error detection

**Key Innovation**: Confidence scoring system that combines multiple signals:
- Structured output: 100 points
- Completion keywords: +10 points
- "Nothing to do" patterns: +15 points
- File changes detected: +20 points
- Output decline >50%: +10 points

Exit signal triggered when confidence ≥ 40 points.

---

### 2. Circuit Breaker Pattern ✅
**File**: `lib/circuit_breaker.sh` (309 lines)
**Expert Recommendation**: Michael Nygard (Production Resilience)

**Features Implemented**:
- ✅ Three-state pattern: CLOSED → HALF_OPEN → OPEN
- ✅ No progress detection (3 consecutive loops)
- ✅ Same error repetition detection (5 consecutive loops)
- ✅ Automatic halt with clear user guidance
- ✅ State transition logging and history
- ✅ Manual reset capability
- ✅ Visual status display with colors

**State Transitions**:

CLOSED (Normal)
↓ (2 loops, no progress)
HALF_OPEN (Monitoring)
↓ (1 loop with progress → CLOSED)
↓ (1 more loop, no progress → OPEN)
OPEN (Halted)
↓ (manual reset only → CLOSED)

text

**Thresholds**:
- No progress threshold: 3 loops
- Same error threshold: 5 loops
- Output decline threshold: 70%

**User Experience**:
When circuit opens, Ralph displays:
- Current circuit state and reason
- Loops since last progress
- Possible causes
- Clear remediation steps
- Manual reset command

---

### 3. Structured Output Contract ✅
**File**: `templates/PROMPT.md` (updated)
**Expert Recommendation**: Sam Newman (Service Integration)

**Contract Format**:

text

**Clear Exit Criteria**:
Claude sets `EXIT_SIGNAL: true` only when ALL conditions met:
1. All fix_plan.md items marked [x]
2. All tests passing (or no tests needed)
3. No errors/warnings in last execution
4. All specs/ requirements implemented
5. Nothing meaningful left to implement

**Examples Provided**:
- Work in progress (EXIT_SIGNAL: false)
- Project complete (EXIT_SIGNAL: true)
- Stuck/blocked (EXIT_SIGNAL: false)

---

### 4. Ralph Loop Integration ✅
**File**: `ralph_loop.sh` (updated)
**Lines Changed**: +93 insertions

**Integration Points**:
1. **Initialization**: Source both library components at startup
2. **Circuit Check**: Check circuit breaker before each loop iteration
3. **Response Analysis**: After Claude execution, analyze output
4. **Signal Updates**: Update .exit_signals file after each loop
5. **Circuit Recording**: Record loop results for stagnation detection
6. **Halt Detection**: Exit gracefully when circuit opens

**Flow**:

Loop Start
↓
Check Circuit (should_halt_execution)
↓ (if OPEN → exit)
Execute Claude Code
↓
Analyze Response (analyze_response)
↓
Update Exit Signals (update_exit_signals)
↓
Record Loop Result (record_loop_result)
↓ (if circuit opens → exit)
Next Loop

**Scenario 2: Test-Only Loop Detected**
- **Given**: Last 3 loops only ran tests, no implementation
- **Then**: OUTPUT WORK_TYPE=TESTING with FILES_MODIFIED=0
- **Ralph's Action**: Increments test_only_loops, exits after threshold

**Scenario 3: Stuck on Recurring Error**
- **Given**: Same error in last 5 loops, no progress
- **Then**: OUTPUT STATUS=BLOCKED with error description
- **Ralph's Action**: Circuit breaker opens after 5 loops

**Scenario 4: No Work Remaining**
- **Given**: All tasks complete, nothing in specs/ to implement
- **Then**: OUTPUT EXIT_SIGNAL=true with COMPLETE status
- **Ralph's Action**: Immediate graceful exit

**Scenario 5: Making Progress**
- **Given**: Tasks remain, files being modified, tests passing
- **Then**: OUTPUT STATUS=IN_PROGRESS with progress metrics

- **Success**: Task completed, files modified/committed, status tracked
- **14-step main scenario** with extensions for:
  - Circuit breaker OPEN → halt with guidance
  - Rate limit exceeded → countdown wait
  - API 5-hour limit → user prompt
  - Execution failure → retry with backoff
  - EXIT_SIGNAL detected → graceful completion
  - Circuit breaker opens → stagnation halt

**UC-2: Detect Project Completion** (Response analysis)
- **Success**: Completion accurately determined, confidence scored
- **7-step main scenario** with extensions for:
  - No structured output → natural language parsing
  - IN_PROGRESS status → work type analysis
  - BLOCKED status → intervention recommendation
  - High confidence → exit even without explicit signal

**UC-3: Prevent Resource Waste** (Circuit breaker)
- **Success**: Runaway loops halted, <1K tokens wasted
- **9-step main scenario** with extensions for:
  - No files changed (1 loop) → monitor
  - No files changed (2 loops) → HALF_OPEN warning
  - No files changed (3 loops) → OPEN and halt
  - Same error (5 loops) → OPEN and halt
  - Files changed → recovery to CLOSED

**UC-4: Handle API Rate Limits**
- **Success**: Rate limits respected, execution continues
- **9-step main scenario** with extensions for:
  - New hour → reset counter
  - Limit reached → countdown wait
  - API error → retry with user prompt

**UC-5: Provide Loop Monitoring** (ralph-monitor)
- **Success**: Real-time status visible, <2s latency
- **9-step continuous monitoring** with extensions for:
  - No status.json → waiting message
  - Circuit OPEN → red alert display
  - Ralph exited → completion summary

**UC-6: Reset Circuit Breaker** (Manual intervention)
- **Success**: Circuit reset, Ralph can resume
- **11-step manual recovery** with extensions for:
  - Cannot determine cause → status commands
  - PROMPT.md issue → edit and clarify
  - Environment issue → fix configuration
