mum

First-time setup for a fresh MUM instance. Use when the knowledge/ folder has no core content yet, or when the user asks to (re)onboard. Interviews the user and writes the initial core knowledge files. Do not use for ongoing knowledge updates during normal work — that's the self-evolve protocol.

Find and maintain the user's knowledge notes. Use to locate which knowledge notes are relevant to a task (run the map tool for progressive disclosure), or when creating, updating, or organizing a domain note. Authority on MUM's knowledge-note format. Do not use for editing the constitution (AGENTS.md) or building skills (see skill-builder).

An explicit pass to improve MUM. Use when the user asks MUM to "evolve", "learn from this", or tidy itself up. Captures durable learnings into knowledge and proposes new or refined skills. Do not auto-run after ordinary work (capture confirmed learnings inline instead), for first-time setup (use the onboarding skill), or for jotting a single fact mid-task (just write it).

Create, refine, or retire MUM skills. Use when the user has a repeatable workflow worth capturing as a skill, wants to improve or fix an existing skill, or wants to remove one. This skill is the authority on MUM's skill format and authoring best practices. Do not use for one-off tasks the agent already handles well.
