Claude Code Plugin

A Claude Code plugin for automating GitHub workflows: code reviews, PR creation, and multi-model second opinions via Gemini.

Installation

1. Add the marketplace:

/plugin marketplace add kwiggen/claude-code-plugin

2. Install the plugin:

/plugin install kw-plugin@claude-code-plugin

3. (Optional) Enable auto-updates:

Run /plugin, go to Marketplaces tab, enable auto-update for claude-code-plugin

Updating

/plugin update kw-plugin@claude-code-plugin

Requirements

• Claude Code v2.0.12 or higher
• GitHub CLI (gh) authenticated
• Git repository with GitHub remote
• (Optional) GEMINI_API_KEY environment variable for Gemini features (dual-review, second opinions, image generation)

Commands

Code Review & PRs

Command	Description
/review-code	Run structured code reviews on uncommitted changes, commits, or GitHub PRs
/create-pr [base]	Create pull requests with AI-generated descriptions

Gemini Integration

Command	Description
/gemini-review	Dual code review from both Claude and Gemini with synthesis
/ask-gemini	Get Gemini's independent opinion on any file, topic, or question
/generate-image	Generate images using Gemini with AI-enhanced prompts
/paper-banana	Publication-quality illustrations via 5-agent pipeline

Requires: GEMINI_API_KEY environment variable. Get a free key at Google AI Studio. If the API key is not configured, the dual-review and advisor commands gracefully fall back to Claude-only behavior.

Planning & Validation

Command	Description
/create-feature	Guide feature definition through discussion, generate a 1-pager
/create-issue	Create a GitHub issue with project fields
/validate	Validate plans, proposals, or architecture with parallel analysis

Learning & Publishing

/teach-me	Pedagogical code walkthrough tailored to your level
/grill-me	Stress-test a plan or design with relentless interviewing
/publish	Convert markdown to portable, shareable HTML with syntax highlighting and tabs
/clip [mode]	Copy the last Claude message to the clipboard, cleaned and reformatted (md, slack, plain, html)

Requirements

• Git repository with GitHub remote

Optional: Gemini API Key

The /gemini-review, /ask-gemini, /generate-image, and /paper-banana commands require a GEMINI_API_KEY environment variable:

1. Get a free API key at Google AI Studio
2. Set the environment variable:

export GEMINI_API_KEY="your-key-here"

If the API key is not configured, the dual-review and advisor commands gracefully fall back to Claude-only behavior. Image generation commands require the key to function.
