Plugin Developer Toolkit

Plugin Developer Toolkit bundles seven focused skills that show how Claude Code plugins are built from the ground up. It reads and explains hook lifecycle, maps plugin manifest structure, shows MCP server registration and auth flows, and demonstrates how slash commands and agent entry points work. The repo includes over a dozen runnable examples so you can open code, run it, and see requests and responses in context.

You get six validation scripts that check manifests, type schemas, and security headers, plus more than 21,000 words of documentation that walks through deployment patterns, error handling, and testing strategies. The package sends ready-to-run dev server configs, example webhooks, and test payloads so you can iterate locally. It also shows how to author new skills and wire them into agent and slash-command flows.

Imagine building a support bot that needs slash commands, background hooks, and an MCP server for auth: the Toolkit provides examples, validation checks, and deploy configs so you can code, test, and deploy without switching between scattered guides and repos. The GitHub repo at https://github.com/anthropics/claude-code stores all examples and scripts for cloning and immediate use.
