Requesting Code Review
Dispatch superpowers:code-reviewer subagent to catch issues before they cascade.
Core principle: Review early, review often.
When to Request Review
Mandatory:
- •After each task in subagent-driven development
- •After completing major feature
- •Before merge to main
Optional but valuable:
- •When stuck (fresh perspective)
- •Before refactoring (baseline check)
- •After fixing complex bug
How to Request
1. Claude extracts git SHAs automatically:
When you request a review, Claude runs via Bash tool:
bash
BASE_SHA=$(git rev-parse origin/main) # or HEAD~1, develop, etc. HEAD_SHA=$(git rev-parse HEAD)
You can specify different base: "Review against develop" or "Review last 3 commits"
2. Claude dispatches code-reviewer subagent:
Uses Task tool with superpowers:code-reviewer type, fills template at code-reviewer.md
Placeholders Claude fills automatically:
- •
{WHAT_WAS_IMPLEMENTED}- What you just built - •
{PLAN_OR_REQUIREMENTS}- What it should do (you provide or Claude infers) - •
{BASE_SHA}- Starting commit (auto-extracted) - •
{HEAD_SHA}- Ending commit (auto-extracted) - •
{DESCRIPTION}- Brief summary (you provide or Claude generates from diff)
3. Act on feedback:
- •Fix Critical issues immediately
- •Fix Important issues before proceeding
- •Note Minor issues for later
- •Push back if reviewer is wrong (with reasoning)
Example
code
[Just completed Task 2: Add verification function]
You: Let me request code review before proceeding.
Claude: [Automatically extracts SHAs]
$ git rev-parse origin/main # a7981ec
$ git rev-parse HEAD # 3df7661
[Dispatches superpowers:code-reviewer subagent]
WHAT_WAS_IMPLEMENTED: Verification and repair functions for conversation index
PLAN_OR_REQUIREMENTS: Task 2 from docs/plans/deployment-plan.md
BASE_SHA: a7981ec
HEAD_SHA: 3df7661
DESCRIPTION: Added verifyIndex() and repairIndex() with 4 issue types
[Subagent returns]:
Strengths: Clean architecture, real tests
Issues:
Important: Missing progress indicators
Minor: Magic number (100) for reporting interval
Assessment: Ready to proceed
You: [Reports findings]
You: [fix progress indicators]
[Continue to Task 3]
Integration with Workflows
Subagent-Driven Development:
- •Review after EACH task
- •Catch issues before they compound
- •Fix before moving to next task
Executing Plans:
- •Review after each batch (3 tasks)
- •Get feedback, apply, continue
Ad-Hoc Development:
- •Review before merge
- •Review when stuck
Red Flags
Never:
- •Skip review because "it's simple"
- •Ignore Critical issues
- •Proceed with unfixed Important issues
- •Argue with valid technical feedback
If reviewer wrong:
- •Push back with technical reasoning
- •Show code/tests that prove it works
- •Request clarification
