Mycelium — Development skill for Claude Code

Mycelium

⚡ Quickstart → Install Mycelium

**A task manager built for coding agents.** Mycelium gives an AI agent (Claude Code, Cursor, Aider, or your own) a durable, git-trackable place to plan and remember work across sessions. State lives in a SQLite file inside your repo, so when an agent's context is cleared, a session ends, or a teammate pulls the branch three days later, the plan is still there: the same epics, tasks, dependencies, and open follow-ups. The agent reconstructs where it left off from `myc list`, not from your memory.

It is a one-shot, scriptable CLI with JSON output and a zero-config data model, which is exactly what an agent needs to drive it reliably. Humans get the same tool (plus an optional desktop GUI, [MycUI](#gui-mycui-pre-built-download)).

Why agents

• State that outlives the session: the plan is a file in the repo (.mycelium/mycelium.db), not the agent's context window. Clear the context, start a new session, or hand the branch to another machine, and the epics, tasks, dependencies, and follow-ups are still intact.
• Git is the sync layer:
