-# Repo Instructions
+# Repository instructions
 
-## Testing
+Cover Story is a browser stealth game whose patrols are planned through the published
+`dancing-links` npm package.
 
-Any feature addition requires thorough testing.
-Use Test-Driven Development (TDD) to guide implementation wherever applicable.
-All new code should be accompanied by appropriate unit test.
-
-## Performance
-
-Performance is absolutely critical to this project.
-If you modify any application logic, you MUST run benchmarks both before and after your changes.
-Ensure that performance has not been negatively impacted.
-Document benchmark results in your pull request description.
-
-## Commit Style
-
-All commits in this repository MUST follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) specification.
-Commits are used to automatically release new versions using `release-it`.
-
-- If you change repository setup, CI flows, or similar meta-configuration, use the `build:` or `ci:` prefix — this prevents a new release from being triggered.
-- The `Initial Plan` commit must be prefixed with `docs:`.
-
-**Examples:**
-
-- `feat: add user authentication module`
-- `fix: resolve API response error`
-- `ci: update workflow for test coverage`
-- `build: update dependencies`
-- `docs: initial plan`
+- Run `npm test`, `npm run lint`, `npm run format:check`, and `npm run build` for changes.
+- Document every optimized path in code, including what it does and why it is faster.
+- Keep scheduling tied to varied live state; do not cache repeated puzzle answers to manufacture a
+  benchmark win.
+- Test every non-identical fallback explicitly.
+- Use Conventional Commits.
