vike Agent Skills & AI Rules

- When changing the docs, consider updating docs/public/llms.txt
- The only thing worse than a failing test is a reduction in test coverage
- A test should never cover trivial code — every test must earn its place by covering something non-trivial (e.g. edge cases, complex logic, subtle behavior, ...).
- When squash-merging a PR, only keep the first line of the commit message and make sure to reference the PR number instead (so we avoid bloating Git history)
