Save, edit, list, or delete a Claude Code skill in this workspace. Use when the user wants to turn a workflow into a reusable skill ("skill 化して", "save this as a skill"), modify or remove one, or list what's registered. Writes one markdown file per skill at `data/skills/<slug>/SKILL.md`; a workspace-side hook mirrors it into `.claude/skills/<slug>/SKILL.md` so Claude Code picks it up.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill manager
A bundled MulmoClaude preset skill (`mc-` prefix = launcher-managed; do not edit
this file in the workspace, it is overwritten on every server boot).
Help the user manage **project-scope** Claude Code skills. The skill *body*
that Claude Code reads lives at `.claude/skills/<slug>/SKILL.md`, but agents
**must not write there directly** — Claude Code's permission system treats
`.claude/` as a self-modification surface and the host GUI cannot answer the
resulting prompt, so the write hangs.
Instead, **edit the staging file** at `data/skills/<slug>/SKILL.md`. A PostToolUse
hook mirrors every Write / Edit / `rm` on those staging files into
`.claude/skills/<slug>/SKILL.md` (or removes the entire dir on delete) and
then asks the server to re-register skills — no restart needed. The user
never sees the staging vs. canonical split; they just say "skill 化して".
The user-scope folder `~/.claude/skills/` is read-only territory managed
outside MulmoClaude — don't touch those.
End with a one-line confirmation ("Saved as foo-skill." / "Removed foo-skill.")
so the user can verify without scrolling.

How to install
mdr add receptron/mulmoclaude/mc-manage-skills@sha256:9b1fa885345437ccThe line at the top of this page pins the label git:20261008.83935cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
