Multi-Agent Code Review

Use TodoWrite to track these 4 phases:

1. Detect languages and scope
2. Spawn review agents
3. Collect agent results
4. Aggregate and present findings

---

Parse $ARGUMENTS:

• deep → 6-12 specialized Claude sub-agents (language-specific reviewers)
• external → Add external AI reviewers (Codex + Gemini). Only if explicitly requested.

IMPORTANT: Without external flag, run ONLY Claude agents. Never run Codex or Gemini unless external is in arguments.

---

Step 1: Detect Language & Ask Scope

Detect languages in changes:

Copygit diff --name-only HEAD | grep -E '\.(go|py|ts|tsx|html|css|js)$' | head -20

Then use AskUserQuestion:

Build git command based on choice.

---

Step 2: Spawn Agents (ALL in ONE message)

Default Mode: Language Engineers

For each detected language, spawn ONE Task:

• Go files → Task(subagent_type="go-engineer", ...)
• Python files → Task(subagent_type="python-engineer", ...)

Deep Mode: Specialized Sub-Agents

Invoke agents by their subagent_type (models defined in agent metadata):

Go agents (if Go files detected):

Python agents (if Python files detected):

TypeScript agents (if TypeScript files detected):

Web agents (if HTML/CSS/JS files detected):

Spawn each agent using its subagent_type directly:

CopyTask(subagent_type="{agent}", prompt="Review code from: {git_command}. Output: file:line - Issue. Fix.")

Agent's own model setting (from metadata) is respected automatically.

External Mode: Add Codex + Gemini (ONLY if external in arguments)

Skip this section entirely if external is NOT in $ARGUMENTS.

If external IS present, spawn these agents IN PARALLEL with Claude agents:

CopyTask(subagent_type="codex-assistant", prompt="review: Review code from {git_command}")
Task(subagent_type="gemini-consultant", prompt="review: Review architecture of {git_command}")

codex-assistant: Code review for security (OWASP), quality, architecture, testing gaps. gemini-consultant: Architecture alternatives and design trade-offs.

Remember: deep alone = Claude agents only. deep external = Claude + Codex + Gemini.

Step 3: Aggregate & Present

Copy## Code Review Summary

**Mode**: {default|deep} {+external}
**Scope**: {description}
**Agents**: {count} reviewers

---

### CRITICAL (Must Fix)

- [{source}] `file:line` - Issue. Fix.

### IMPORTANT (Should Fix)

- [{source}] `file:line` - Issue. Fix.

### SUGGESTIONS

- [{source}] `file:line` - Issue. Fix.

---

### Consensus (Multi-Agent Agreement)

| Issue | Flagged By | Confidence |
| ----- | ---------- | ---------- |
| ...   | ...        | High       |

### Recommended Actions
