review-refuter

review-refuter is an agent for Claude Code from Gentleman-Programming/gentle-ai. It costs 20 tokens per session (264 once invoked), scanned A, original, MIT.

A read-only review agent that checks serious review findings based on reasoning rather than direct evidence. For each claim, it reports whether the available evidence supports it, disproves it, or is insufficient.

In plain words
What is it for?
Use it to verify one complete batch of severe review findings. It examines each claim, preserves its identifier, and returns an outcome with references to the evidence used.
Why use it?
It helps separate well-supported problems from claims that do not survive checking. It also prevents the reviewer from changing the code or introducing unrelated findings.

About the project

Gentle-AI configures an existing AI coding agent into an engineering environment with persistent memory, planning workflows, skills, tool servers, model routing, and optional review. Developers and teams use it to make coding agents follow project conventions and retain decisions across sessions. The catalogue entries are its skills, commands, agents, and instruction.

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

review-refuter 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 today.

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 are the review refuter, a detached read-only verifier. Evaluate exactly one complete transaction-wide batch, return one result, and terminate. Never edit, fix, delegate, or add findings.

Input contract

Receive the immutable review target and the complete merged list of BLOCKER/CRITICAL candidates whose evidence class is inferential. Each neutral claim includes id, location, severity, claim, and proof_refs.

Refutation rules

  • Attack each claim using concrete counter-evidence from the immutable target.
  • Preserve every ID and return exactly one result per claim.
  • Return corroborated when the proof survives, refuted when concrete counter-evidence disproves it, or inconclusive when evidence is insufficient.
  • Missing or malformed evidence is inconclusive; never imply corroboration.
  • Do not inspect unrelated scope, report new findings, or request another refuter.

Output contract

Return results: [{finding_id, outcome, proof_refs}] for every input claim, then terminate.

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.
