# Review Context

- Changed files: !`git diff --name-only HEAD~1 2>/dev/null || echo "No recent commits"`

- Staged files: !`git diff --staged --name-only`

## Code Review

**Scope**: $ARGUMENTS

Delivers **focused, streamlined** Rust code reviews matching stated task

requirements exactly. No over-analysis.

## Rust Standards

See `references/rust-best-practices.md` for comprehensive Rust guidelines.

## Workflow

1. **Read task requirements** to understand expected scope

2. **Check validation passes** before detailed review

3. **Match review depth** to task complexity (simple vs complex)

4. **Validate requirements** — does implementation match task scope exactly?

5. **Issue focused feedback** with specific file paths and line numbers

## Review Strategy

**Simple Tasks (single module)**: Safety, error handling, requirements match,

basic quality

**Complex Tasks (multi-module)**: Above plus architecture, ownership patterns,

async correctness, comprehensive testing

**Always**: Use existing project patterns, check for unsafe blocks

## Review Checklist

**Safety & Security**:

- [ ] No unnecessary `unsafe` blocks (every block has `// SAFETY:` comment)

- [ ] No `unwrap()`/`expect()` in production paths

- [ ] All external input validated at boundaries

- [ ] `cargo audit` clean (no known CVEs)

**Requirements Match**:

- [ ] Implements exactly what was requested

- [ ] No over-engineering or scope creep

- [ ] Appropriate complexity level

**Code Quality**:

- [ ] Follows project patterns in `src/`

- [ ] Proper error handling with `?` and typed errors

- [ ] Ownership/borrowing patterns correct (no unnecessary clones)

- [ ] Tests cover stated functionality

**Structural Health**:

- [ ] No function exceeds cognitive complexity threshold

- [ ] No copy-paste duplication across methods

- [ ] `pub(crate)` used for crate-internal types

## Output Standards

**Simple Tasks**: CRITICAL issues only, clear approval when requirements met

**Complex Tasks**: CRITICAL/WARNINGS/SUGGESTIONS with specific fixes

**All reviews**: Concise, streamlined, no unnecessary complexity analysis
