mutsu: Skill for Claude Code

.agents/skills/ecosystem-lock-board-rotation/SKILL.md

ecosystem-lock-board-rotation is a skill for Claude Code, Codex from tokuhirom/mutsu. It costs 145 tokens per session (2,101 once invoked), scanned A, original, Artistic-2.0.

A procedure for replacing an overgrown issue used as the shared board for ecosystem locks. It carries active locks to a new issue, moves the label, closes the old issue with a redirect, and updates references.

In plain words
What is it for?
Use it when the issue labelled `ecosystem:lock` has too many comments. It helps maintain a single current issue while preserving links from the previous one.
Why use it?
A large issue comment history can become too difficult to read or retrieve in one request. Rotating the board keeps current locks accessible without losing them.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is tokuhirom/mutsu's own configuration. It tells Claude Code and Codex how to work on mutsu itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mutsu configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ecosystem-lock-board-rotation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (live-locks.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
