spec-compliance-checker
what it does
Checks one documented requirement against the code that should implement it, and returns a verdict with the lines that evidence it. Writes its analysis to disk and returns a compact record. Use for a single requirement; use the spec-compliance workflow for a whole document.

Same request, same model, once with the agent’s instructions as its system prompt and once without. Neither could use a tool. Read both and judge for yourself.

“Check this requirement: "Password reset tokens must expire 30 minutes after creation and be single-use." Here's the code: def create_reset_token(user): token = secrets.token_urlsafe(32) db.save(ResetToken(user_id=user.id, token=token, created_at=now(), used=False)) return token def redeem_token(token): t = db.get(ResetToken, token=token) if t is None or t.used: raise InvalidToken() t.used = True db.save(t) return t.user_id Does it comply? Give me a verdict and the lines that back it up.”
example-2
“Single requirement from our API doc: "All list endpoints must return at most 100 items per page, and requests with a limit above 100 must be rejected with HTTP 400." The handler is: @app.get('/orders') def list_orders(limit: int = 50, offset: int = 0): limit = min(limit, 100) rows = db.query(Order).offset(offset).limit(limit).all() return rows Is this compliant? Please give a verdict and cite the evidence lines.”
Download the .zip and unzip it. Put spec-compliance-checker.md here:
~/.claude/agents/Every project. For one project only, use .claude/agents/ inside it. It gives the agent the tools it asks for, and no others.~/.cursor/agents/Cursor also reads the Claude Code folder above. It has no tools field, so it gives every agent every tool, whatever this one asks for.Keep its license file beside it, as spec-compliance-checker.LICENSE: a name that doesn’t end in .md, since every .md file there is read as an agent.
Then start a new session and ask for it by name. Folders checked 6 November 2026.
Or install from your agent: ask it to install spec-compliance-checker from Carte Blanche.
