Agent Alchemy — Claude Code Toolkit

An open-source toolkit that extends Claude Code into a structured development platform — turning ideas into specs, specs into tasks, and tasks into autonomous execution. Everything is built with Claude Code, for Claude Code: the plugins are plain markdown, readable and version-controlled like any other code.

Six plugin groups deliver 28 skills and 16 agents spanning spec-driven and test-driven development, code review, architecture, and Git automation — coordinated with a Next.js real-time Kanban dashboard and a VS Code extension for plugin authoring.

Key capabilities:

• End-to-end spec-driven pipeline: create-spec → analyze-spec → create-tasks → execute-tasks with wave-based autonomous execution
• Real-time task manager that watches the task directory via filesystem events and streams updates over Server-Sent Events
• Model-tiered execution (Opus for reasoning, Sonnet for exploration, Haiku for quick tasks) plus a VS Code extension with schema validation and YAML frontmatter autocomplete
