turnstile-code-reviewer

turnstile-code-reviewer is a skill for Claude Code, Codex from febradc-github/turnstile. It costs 50 tokens per session (409 once invoked), scanned A, original, MIT.

A code-review workflow that examines code or a change set for correctness problems and unnecessary complexity. It is advisory and does not change tickets or commit code.

In plain words
What is it for?
Use it to review specified files or current uncommitted changes, while also checking project notes for known issues or design decisions.
Why use it?
It helps find bugs, edge cases, incorrect assumptions, duplicated logic, and utilities that could simplify the change before it is accepted.

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-code-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 3d 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

Code Reviewer

Process

  1. Determine the review target: files or scope from $ARGUMENTS, else git diff / git status for the current uncommitted changes. Nothing to review (no changes, no target): say so and ask what they'd like reviewed.
  2. Search the vault for notes on the affected area. Surface anything relevant -- known gotchas, and any ADR the change might contradict -- before reviewing.
  3. Review for: correctness bugs (logic errors, edge cases, incorrect assumptions) and reuse/simplification (duplicated logic, unnecessary complexity, existing utilities that should be used).
  4. Report findings as a list -- file/location, what's wrong, why it matters. Nothing significant: say so plainly rather than inventing nitpicks.
  5. If a finding reveals a durable gotcha worth remembering (not a one-off bug), dispatch brain-curator with a short description.
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.
