Extract Spec
Extract a provisional VDM-SL specification from existing source code. This is NOT the true spec — it is a scaffold for dialogue to uncover the user's real intent. Triggered by: "extract spec from code", "reverse engineer the specification", "extract-spec", "code to spec", "formalize the existing code". Japanese: 「既存のコードから仕様を抽出して」「コードの仕様を形式化して」 「コードベースを分析して」「コードをリバースエンジニアリングして」
Works with: Claude Code (native) · Cursor, Codex CLI (manual)

Security audit
Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.
Its own instructions
Its SKILL.md shows worked examples and covers setup.
Read from the capability’s own SKILL.md. This is not a grade and does not compare to the instruction-depth verdict on an MCP server — a skill has no tools to document, so that rubric does not apply to it.
You searched for one. Check the rest of your stack:
npx tashan-cli doctorReads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.
Pro adds the history to tashan doctor, so a run over your own config says which of yours gained an advisory, started running an install script, or lost its last maintainer — and what to move to.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.
Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
