Code Guardian — Production Readiness Plugin for Claude Code

A Claude Code plugin that enforces production-readiness standards across any project. Audits codebases against industry best practices, checks branch strategy, validates testing and CI/CD setup, and computes a quality scorecard.

Features

Transports

• stdio — Runs as a subprocess (Claude Code's default plugin transport)

• HTTP/SSE — Listens on http://localhost:8765 for direct MCP protocol access

Installation

The plugin is already installed at:

~/.claude/plugins/cache/claude-plugins-official/code-guardian/v1/

To install manually:

cp -r ~/.claude/plugins/cache/claude-plugins-official/code-guardian/v1 \
       ~/.claude/plugins/cache/claude-plugins-official/code-guardian/<version>/

Then register it in ~/.claude/plugins/installed_plugins.json.

Usage

Once installed, Claude Code will automatically load the plugin. The tools are available as MCP tools — invoke them directly or ask Claude to run an audit:

"Run code-guardian and audit this project" "Check my production readiness score" "Is my branch naming compliant?" "Run a security scan with npm audit"

Extending

Add a new tool by:

1. Implementing the function in src/tools.js

2. Adding it to the TOOLS array and dispatch switch in src/stdio-server.js and src/http-server.js

3. Updating .mcp.json if a new transport config is needed
