Agent Alchemy — Claude Code Toolkit

Developer Tools

An ecosystem of 6 Claude Code plugin groups (28 skills, 16 agents), a real-time task-manager dashboard, and a VS Code extension

01 / Overview

An open-source toolkit that extends Claude Code into a structured development platform by 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, all coordinated with a Next.js real-time Kanban dashboard and a VS Code extension for plugin authoring.

02 / System capabilities

What the system does

  • 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
