name: multi-ai-code-review description: Run multi-provider code reviews over git diffs/PR changes using headless AI CLIs (Claude Code claude, Google gemini, optionally GitHub copilot) and output structured findings + an optional synthesized report; use for security/bug/perf review of recent changes and for generating PR-ready review comments. version: 1.0.0 allowed-tools: bash

Multi-AI Code Review

This skill runs independent code reviews using external headless AI CLIs and produces a structured report you can paste into a PR.

Quick start (git diff)

Unstaged diff:

node codex-skills/multi-ai-code-review/scripts/review.js --providers claude,gemini

Staged diff:

node codex-skills/multi-ai-code-review/scripts/review.js --staged --providers claude,gemini

Diff range (example: typical PR branch):

node codex-skills/multi-ai-code-review/scripts/review.js --range origin/main...HEAD --providers claude,gemini

Output formats

• --output json (default): machine-readable results + optional synthesis
• --output markdown: PR comment format

CI-friendly mode (strict JSON-only)

Use --ci to force stable CI behavior:

• implies --no-synthesis
• forces --output json
• exits non-zero if any provider fails or returns non-parseable JSON

Example:

node codex-skills/multi-ai-code-review/scripts/review.js --ci --range origin/main...HEAD --providers claude,gemini > ai-review.json

Auth behavior (session-first)

Default is --auth-mode session-first:

1. Try CLI using your existing logged-in session/subscription (keys temporarily hidden)
2. If that fails and env keys exist, retry using env keys

To flip:

node codex-skills/multi-ai-code-review/scripts/review.js --auth-mode env-first --providers claude,gemini

Environment variables

• Claude: ANTHROPIC_API_KEY (optional if already logged in)
• Gemini: GEMINI_API_KEY or GOOGLE_API_KEY (optional if already logged in)
• Copilot: uses its own CLI auth flow

Optional: critique the review itself

Pipe the generated review into the existing response-rater skill:

node codex-skills/multi-ai-code-review/scripts/review.js --output markdown | node codex-skills/response-rater/scripts/rate.js --providers claude,gemini

Notes / constraints

• Requires network access to contact providers.
• For very large diffs, the runner samples hunks and reports what was omitted.
