secondpass-multireview

secondpass-multireview

A Claude Code plugin that sends your plans and code changes to other AI models for a second opinion via OpenRouter.

When you invoke /secondpass-multireview:secondpass_multireview, Claude gathers your current plan, the git diff, and surrounding code context, then sends it to GPT-5.3 Codex and Gemini 3.1 Pro in parallel. You get back a structured review from each model covering correctness, risks, simplicity, and missing pieces.

Installation

# Add the marketplace (one time)
/plugin marketplace add stopman/secondpass-multireview

# Install the plugin
/plugin install secondpass-multireview@secondpass-multireview

Setup

Set your OpenRouter API key:

export OPENROUTER_API_KEY="sk-or-v1-..."

Get a key at openrouter.ai/keys.

Usage

During any Claude Code session, invoke the skill:

/secondpass-multireview:secondpass_multireview

Claude will:

1. Gather your current plan summary
2. Collect the git diff of your changes
3. Read relevant surrounding code for context
4. Send all three sections to GPT-5.3 Codex and Gemini 3.1 Pro
5. Present each model's review and synthesize the feedback

Customizing Models

Override the default models with an environment variable:

export SECONDPASS_MODELS="anthropic/claude-sonnet-4-6,meta-llama/llama-4-maverick"

Any model available on OpenRouter works.

How It Works

• No external dependencies — uses Python stdlib only (urllib, json, concurrent.futures)
• Parallel queries — all models are queried simultaneously
• Structured input — models receive the plan, diff, and code context so reviews are grounded in actual code
• Concise output — each model's review is capped at ~400 words
