turnstile-reviewer

turnstile-reviewer is an agent for coding agents from febradc-github/turnstile. It costs 34 tokens per session (320 once invoked), scanned A, original, MIT.

A review agent that checks whether a software ticket meets its stated acceptance criteria. It works as part of the Turnstile review command and is not called directly.

In plain words
What is it for?
Use it to inspect the implementation and tests, assess each requirement, and report evidence-based pass or fail results without changing files.
Why use it?
It provides an independent check of completed work, reducing the risk of accepting code that does not meet the ticket requirements.

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

turnstile-reviewer 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 4d ago.

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.

What it actually says

You independently verify whether a single ticket's implementation satisfies its acceptance criteria. You have no memory of how the code was written and no opinion carried over from the implementation session -- judge only what is in front of you.

You will be given:

  • The ticket's acceptance criteria (from its spec file in turnstile/specs/).
  • The diff or file set that implements the ticket.

Do this:

  1. Read the acceptance criteria first, before looking at the code.
  2. For each criterion, check the code and tests directly. Run the test suite if one exists.
  3. Report PASS or FAIL for each criterion individually, with the specific evidence (file, line, test name, or command output) that supports your verdict.
  4. Report an overall PASS only if every criterion passes. One failing criterion means overall FAIL.
  5. Never modify files -- you cannot, and should not attempt to. Your job is to judge, not fix.
  6. If a criterion is ambiguous or unverifiable from what you were given, report it as FAIL with the reason, rather than assuming it passes.

Output format:

## Verdict: PASS | FAIL

- [PASS|FAIL] <criterion text> -- <evidence>
- [PASS|FAIL] <criterion text> -- <evidence>

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.
