ai-writing-detector

ai-writing-detector is a skill for Codex from conorbronsdon/avoid-ai-writing. It costs 44 tokens per session (864 once invoked), scanned A, original, MIT.

A detect-only skill that scans text for patterns associated with AI-generated writing and reports findings without rewriting it.

In plain words
What is it for?
Use it to audit writing for flagged patterns, apply the stated rulebook, and collect a local detector result when the host can run Node.
Why use it?
It separates detection from editing, reducing the risk that the text changes before its patterns are reviewed.

About the project

avoid-ai-writing is a portable writing skill that detects common patterns associated with AI-generated prose and can rewrite them or make targeted edits to prose files. It is for users of Claude Code, OpenClaw, Hermes, and other compatible coding agents who want text to sound more like human writing. The catalogue entries are the skill's rule and instruction components.

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

ai-writing-detector 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 5d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/detect.js, scripts/patterns.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI Writing Detector

Run a detect-only review using the original Avoid AI Writing rules. Never rewrite unless the user changes the request.

Authority

The canonical rulebook is ../avoid-ai-writing/SKILL.md. Its cautions about false positives, context, protected material, and authorship claims apply here.

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

Connection contract

Incoming

Accept detector work from:

  • avoid-ai-writing-router via ROUTE for detect-only requests, the audit stage of a multi-stage request, or fresh signal collection after another terminal stage returns control to the router.
  • preservation-verifier via bounded RECHECK only when convergence or residual auditing was part of the request.

Do not accept a direct handoff from false-positive-reviewer. That Skill is terminal in the graph and must return control to avoid-ai-writing-router when fresh signal collection is needed. This prevents a reviewer-detector cycle.

Carry forward the existing context_mode, protected constraints, pass state, and risk flags. Do not reset them.

Produce

Update the handoff envelope with:

  • execution_evidence.detector: executed only if the bundled detector actually ran, otherwise model_only.
  • detector_summary.score and label only when produced by executed detector code.
  • detector_summary.issue_types from actual findings.
  • any consequential_authorship_claim risk flag observed in the user's request.

Outgoing

  • FEED findings to voice-preserving-rewriter only when the user also requested returned-text rewriting.
  • FEED findings to file-edit-in-place only when the user explicitly requested mutation of a named file.
  • ESCALATE to false-positive-reviewer when the user asks what the findings can establish about authorship or another consequential conclusion.
  • Otherwise stop after the detect-only result.

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.
