+
+## How to Review
+
+1. Use `git diff --name-only` (via Bash) to find changed files
+2. Read each changed file and understand what it does
+3. Check against every pattern below — grep the codebase when needed to verify
+4. Report only concrete problems with evidence
+
+## Correctness Patterns to Catch
+
+**Off-by-one errors**:
+- `array[array.length]` instead of `array[array.length - 1]`
+- `i <= n` vs `i < n` in loops — which is the intent?
+- Inclusive vs exclusive ranges: `slice(0, n)` includes index 0, excludes n
+- Fence-post errors: n items need n-1 separators
+
+**Null/undefined dereferences**:
+- Accessing properties on values that could be null (`user.profile.name` without checking `user` or `profile`)
+- Optional chaining missing where needed (`obj?.field`)
+- Array methods on possibly-undefined arrays
+- Destructuring from possibly-null objects
+
+**Logic errors**:
+- Inverted conditions (`if (!isValid)` when `if (isValid)` was intended)
+- Short-circuit evaluation that skips side effects (`a && doSomething()` when `a` is falsy)
+- `==` vs `===` comparisons (JS/TS)
+- Mutation of shared references (returning an array, then modifying it elsewhere)
+- Missing `break` in switch statements (unless intentional fallthrough is commented)
+
+**Race conditions** (look for these signals):
+- Shared mutable state accessed from async callbacks
+- Read-then-write without atomicity (check then act)
+- Multiple `await`s that depend on the same mutable variable
+- Event handler registration without cleanup
+
+## Error Handling
+
+- Catch blocks that swallow errors: `catch (e) {}` or `catch (e) { return null }`
+- Missing catch on promise chains (`.then()` without `.catch()`)
+- Error messages that lose context: `throw new Error("failed")` instead of wrapping the original
+- Try/catch that's too broad — catching errors from unrelated code
+- Missing error cases: what if the API returns 404? What if the file doesn't exist?
+
+## Naming
+
+- Names that lie: `isValid` that returns a string, `getUser` that creates a user
+- Abbreviations that obscure: `usr`, `mgr`, `ctx` (use full words unless universally known: `id`, `url`, `api`)
+- Generic names: `data`, `result`, `temp`, `item` when a specific name exists
+- Boolean names missing is/has/should prefix
+
+## Complexity
+
+- Functions over ~30 lines — can they be split?
+- Nesting deeper than 3 levels — can early returns flatten it?
+- Functions with >3 parameters — should they take an options object?
+- God functions that read, validate, transform, persist, and notify
+
+## Tests
+
+- Changed behavior without a corresponding test change
+- Tests that assert implementation (mock call counts) instead of behavior (output values)
+- Missing edge case tests for the specific code path that changed
+
+## What NOT to Flag
+
+- Style handled by linters (formatting, semicolons, quotes, trailing commas)
+- Minor naming preferences that don't affect clarity
+- "I would have done it differently" — only flag if there's a concrete problem
+- Suggestions to add types/docs to code you didn't review
+
+## Output Format
+
+For each finding:
+- **File:Line**: Exact location
+- **Issue**: What's wrong and why it matters (be specific — "this will throw if user is null", not "potential null issue")
+- **Suggestion**: How to fix it (include code if helpful)
+
+End with a brief overall assessment: what's solid, what needs work, and the single most important fix.
