# Requesting Code Review

Dispatch Codex as a read-only reviewer to catch issues before they cascade. The reviewer gets precisely crafted context for evaluation — never your session's history. This keeps the reviewer focused on the work product, not your thought process, and preserves your own context for continued work.

**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. Get git SHAs:**
```bash
BASE_SHA=$(git rev-parse HEAD~1)  # or origin/main
HEAD_SHA=$(git rev-parse HEAD)
```

**2. Dispatch Codex as reviewer:**

用 `/codex:rescue --fresh --wait` 把 `code-reviewer.md` 模板（含 `{BASE_SHA}`/`{HEAD_SHA}` 占位与 `git diff` 指令）交 Codex 只读审查。

**Placeholders:**
- `{DESCRIPTION}` - Brief summary of what you built
- `{PLAN_OR_REQUIREMENTS}` - What it should do
- `{BASE_SHA}` - Starting commit
- `{HEAD_SHA}` - Ending commit

**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

```
[Just completed Task 2: Add verification function]

You: Let me request code review before proceeding.

BASE_SHA=$(git log --oneline | grep "Task 1" | head -1 | awk '{print $1}')
HEAD_SHA=$(git rev-parse HEAD)

[Dispatch Codex as reviewer via /codex:rescue --fresh --wait]
  DESCRIPTION: Added verifyIndex() and repairIndex() with 4 issue types
  PLAN_OR_REQUIREMENTS: Task 2 from research-wiki/plans/deployment-plan.md
  BASE_SHA: a7981ec
  HEAD_SHA: 3df7661

[Codex returns]:
  Strengths: Clean architecture, real tests
  Issues:
    Important: Missing progress indicators
    Minor: Magic number (100) for reporting interval
  Assessment: Ready to proceed

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 task or at natural checkpoints
- 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

## Wiki Integration

**Precondition**: `research-wiki/` directory exists (skip this section entirely if it does not).

**Trigger**: When requesting a code review or when a clear review result has been received.

**Type**: `review`

**Severity**: `approved` / `needs_changes` / `rejected`

**Steps**:
1. Run `.claude/tools/research_wiki.py add_entity research-wiki/ --type review --id <slug> --title "<review title>"` to create the review entity
2. Append the review conclusion, key issues, recommendations, and whether it passed to the generated page
3. If the review recommendations change a design or plan, run `.claude/tools/research_wiki.py add_edge research-wiki/ --from "review:<id>" --to "<target-type>:<id>" --type informs --evidence "..."`
4. Run `.claude/tools/research_wiki.py rebuild_index research-wiki/`
