skill-optimizer

Open-source marketplace of Claude Code plugins (commands, hooks, agents, skills, MCPs, and bundles) in the standard Claude plugin layout.

What’s inside

• •.claude-plugin/marketplace.json — catalog of all plugins (regenerated from plugins/)
• •plugins/ — actual plugins scoped by type:

- commands/ — slash command plugins - hooks/ — event hook plugins with hooks/hooks.json - agents/ — subagent plugins - skills/ — Agent Skills with SKILL.md - mcp/ — MCP server plugins (.mcp.json) - bundles/ — multi-component bundles

• •scripts/generate-marketplace.js — rebuilds the marketplace catalog from manifests

Quick start

1) Install or update the catalog after changes:

node scripts/generate-marketplace.js

2) Add the marketplace locally and install a plugin (from repo root in Claude Code):

/plugin marketplace add ./
/plugin install dev-docs@claudesmith-marketplace

3) Validate manifests (optional):

claude plugin validate .

Adding a new plugin

Each plugin lives under plugins/<category>/<name>/ with a manifest at .claude-plugin/plugin.json and component directories at the plugin root (not inside .claude-plugin/).

Minimal manifest example:

{
  "name": "my-plugin",
  "version": "0.1.0",
  "description": "What this plugin does",
  "author": { "name": "Your Name" },
  "license": "MIT",
  "keywords": ["team", "feature"]
}

After adding files, run node scripts/generate-marketplace.js to refresh marketplace.json.

Conventions

• •Manifests: .claude-plugin/plugin.json required; keep paths relative; use ${CLAUDE_PLUGIN_ROOT} in scripts/hooks.
• •Hooks: config in hooks/hooks.json; scripts in scripts/ and executable.
• •Skills: skills/<skill-name>/SKILL.md with frontmatter.
• •MCP: .mcp.json or mcpServers in manifest; commands may use npx or bundled binaries.
• •Tags: set keywords in plugin.json; generator merges category + keywords into marketplace tags.
