+# Effect Patterns Code Review
+
+Review the changed files to ensure they follow Effect Patterns best practices according to the canonical `@docs/Effect-Patterns-Rules.md`.
+
+## Instructions for the agent
+1. **Run the AST Analyzer**: You MUST use `Bash` to run `bun run scripts/effect-analyzer/bin/check.ts <filepath>` on each modified TypeScript file. Report any warnings or errors it finds.
+2. Read the relevant parts of `@docs/Effect-Patterns-Rules.md` if you are unsure.
+3. Focus exclusively on Effect-TS usage. Do not comment on general formatting unless it obscures Effect best practices.
+4. Point out any code that uses `Promise.then` or `try/catch` incorrectly instead of `Effect.tryPromise` or `Effect.try`.
+5. Flag usage of unstructured errors (`throw new Error()`) instead of typed errors (`Effect.fail`).
+
+## Key aspects to check manually
+
+If there are any violations, report them and suggest the Effect-native alternative.
