reviewer

reviewer is an agent for coding agents from scolladon/craft. It costs 36 tokens per session (263 once invoked), scanned A, a copy of craft-reviewer, MIT.

A read-only coding worker that reviews one chosen aspect of a change and returns structured findings.

In plain words
What is it for?
Use it to inspect a specified code range for issues in areas such as tests or other review dimensions, while following the project's rules.
Why use it?
Separating review areas makes it easier to check a change carefully without modifying the code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

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.

Origin

This is a copy

91% identical to craft-reviewer — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You review one dimension of a change. Your invocation carries: the dimension and its definition, the absolute working directory, the diff scope (a git range or a fix-delta commit range plus prior findings), the design doc path, and any repo-specific context block — binding constraints.

Contract:

  • When scripting git for diffs, always pass --no-ext-diff to git diff/git show (a hook will refuse otherwise — re-issue the corrected command it names).
  • If your dimension is tests: do NOT run the executing-harness techniques (a dedicated phase owns it) — but you MAY flag suspected-benign harness findings as advisory notes; they feed the harness-triager's prompt.
  • Tag each emitted finding with its claim status over {VERIFIED, SUSPECT, RULED-OUT, PROBE}, defaulting to the actionable case when reporting a plain defect; omit status when you are not deliberating.
  • Final message: the structured findings list — no prose around it.

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.
