Code Review Assistant

Perform thorough code reviews focusing on correctness, security, performance, and maintainability.

Behavior

Without Arguments (Review Staged Changes)

1. Run git diff --cached to get staged changes
2. If nothing staged, run git diff for unstaged changes
3. Analyze each file's changes

With PR Number/URL

1. Use gh pr view <number> --json to get PR details
2. Use gh pr diff <number> to get the diff
3. Review all changes in the PR

Context Gates (Read-Only)

Before finalizing review findings, run read-only context gates:

• Check .ai-factory/ARCHITECTURE.md (if present) for boundary/dependency alignment issues.
• Check .ai-factory/RULES.md (if present) for explicit convention violations.
• Check .ai-factory/ROADMAP.md (if present) for milestone alignment and mention missing linkage for likely feat/fix/perf work.

Gate result severity:

• WARN for non-blocking inconsistencies or missing optional files.
• ERROR only for explicit blocking criteria requested by the user/review policy.

/aif-review is read-only for context artifacts by default. Do not modify context files unless user explicitly asks.

Project Context

Read .ai-factory/skill-context/aif-review/SKILL.md — MANDATORY if the file exists.

This file contains project-specific rules accumulated by /aif-evolve from patches, codebase conventions, and tech-stack analysis. These rules are tailored to the current project.

How to apply skill-context rules:

• Treat them as project-level overrides for this skill's general instructions
• When a skill-context rule conflicts with a general rule written in this SKILL.md, the skill-context rule wins (more specific context takes priority — same principle as nested CLAUDE.md files)
• When there is no conflict, apply both: general rules from SKILL.md + project rules from skill-context
• Do NOT ignore skill-context rules even if they seem to contradict this skill's defaults — they exist because the project's experience proved the default insufficient
• CRITICAL: skill-context rules apply to ALL outputs of this skill — including the review summary format and the checklist criteria. If a skill-context rule says "review MUST check X" or "summary MUST include section Y" — you MUST augment the output accordingly. Producing a review that ignores skill-context rules is a bug.

Enforcement: After generating any output artifact, verify it against all skill-context rules. If any rule is violated — fix the output before presenting it to the user.

## Code Review Summary

**Files Reviewed:** [count]
**Risk Level:** 🟢 Low / 🟡 Medium / 🔴 High

### Context Gates
[Architecture / Rules / Roadmap gate results with WARN/ERROR labels]

### Critical Issues
[Must be fixed before merge]

### Suggestions
[Nice to have improvements]

### Questions
[Clarifications needed]

### Positive Notes
[Good patterns observed]

Review Style

• Be constructive, not critical
• Explain the "why" behind suggestions
• Provide code examples when helpful
• Acknowledge good code
• Prioritize feedback by importance
• Ask questions instead of making assumptions

Examples

User: /aif-review Review staged changes in current repository.

User: /aif-review 123 Review PR #123 using GitHub CLI.

User: /aif-review https://github.com/org/repo/pull/123 Review PR from URL.

Integration

If GitHub MCP is configured, can:

• Post review comments directly to PR
• Request changes or approve
• Add labels based on review outcome

Tip: Context is heavy after code review. Consider /clear or /compact before continuing with other tasks.
