Monitors Claude Code's actions by running a Node.js observer script after every tool use, enabling logging and change detection for debugging or auditing workflows.
Open-source marketplace of Claude Code plugins (commands, hooks, agents, skills, MCPs, and bundles) in the standard Claude plugin layout.
.claude-plugin/marketplace.json — catalog of all plugins (regenerated from plugins/)plugins/ — actual plugins scoped by type:
commands/ — slash command pluginshooks/ — event hook plugins with hooks/hooks.jsonagents/ — subagent pluginsskills/ — Agent Skills with SKILL.mdmcp/ — MCP server plugins (.mcp.json)bundles/ — multi-component bundlesscripts/generate-marketplace.js — rebuilds the marketplace catalog from manifestsnode scripts/generate-marketplace.js
/plugin marketplace add ./
/plugin install dev-docs@claudesmith-marketplace
claude plugin validate .
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.
.claude-plugin/plugin.json required; keep paths relative; use ${CLAUDE_PLUGIN_ROOT} in scripts/hooks.hooks/hooks.json; scripts in scripts/ and executable.skills/<skill-name>/SKILL.md with frontmatter..mcp.json or mcpServers in manifest; commands may use npx or bundled binaries.keywords in plugin.json; generator merges category + keywords into marketplace tags.Matches all tools
Hooks run on every tool call, not just specific ones
