false-positive-reviewer

false-positive-reviewer is a skill for Codex from PracticalSwan/agent-skills. It costs 49 tokens per session (1,355 once invoked), scanned A, original, MIT.

A review guide for interpreting AI-writing detector results without treating them as proof of who wrote a text. It separates detector evidence, editorial observations, user-provided context, and missing evidence.

In plain words
What is it for?
Use it to assess claims about AI authorship and explain what detector results can and cannot show, especially when the decision has serious consequences.
Why use it?
AI-writing detectors can produce false positives, so their flags do not by themselves prove authorship. This helps avoid unsupported conclusions in academic, hiring, publishing, or disciplinary decisions.

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

false-positive-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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

False-Positive Reviewer

Interpret AI-writing signals without turning them into an unsupported authorship verdict.

Authority

Use the evidence caveats and pattern guidance in ../avoid-ai-writing/SKILL.md. The original Skill explicitly treats flags as writing-quality signals, not proof of who or what wrote the text.

For cross-Skill work, follow ../avoid-ai-writing-router/references/handoff-contract.md and ../avoid-ai-writing-router/references/skill-graph.json.

Connection contract

Incoming

Accept interpretation work from:

  • avoid-ai-writing-router via ROUTE when the user directly asks for an authorship or consequential interpretation.
  • ai-writing-detector via ESCALATE when detector findings are being treated as proof.
  • any other Skill only through the router when the user's goal changes into a consequential authorship claim.

Preserve the distinction between:

  • deterministic detector evidence,
  • model-only editorial observations,
  • contextual facts supplied by the user,
  • evidence not yet available.

Produce

Update the handoff envelope only with interpretation-relevant state:

  • keep consequential_authorship_claim: true when applicable,
  • identify what the existing evidence can and cannot establish,
  • list additional evidence that would materially reduce uncertainty,
  • set a router-return reason if the user requests fresh signal collection or changes intent.

Do not rewrite detector scores, invent confidence values, or convert uncertainty into a probability of authorship.

Terminal behavior

This Skill has no direct outgoing Skill edge.

If fresh signal collection is genuinely needed, return control to avoid-ai-writing-router with fresh_signal_collection_needed. The router may run ai-writing-detector and then route the updated evidence back for interpretation if the user's request still requires it.

If the user separately asks to rewrite or edit the text, return control to the router with the new intent. Do not jump directly into rewrite or mutation from this Skill.

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.
