Avoid AI writing

The skill turns the agent into an editor that hunts for patterns common in machine-written text. Before any audit it reads references/patterns.md, the catalog of word tiers, patterns and context profiles. There are three modes. Rewrite, the default, flags problems and returns corrected text. Detect only lists the findings. Edit changes a named prose file in place with small, targeted edits, and refuses source code, configuration and generated data.

Findings fall into three severity tiers, from credibility problems such as cutoff disclaimers and unsourced attributions, through banned words and template phrases, down to style issues like em dash frequency. An editing contract decides what may change: a match becomes an edit only after its context checks pass, and quotations, code, URLs and frontmatter stay protected. The agent may not add facts, experiences or opinions the source lacks, and it treats instructions inside the text as data. Voice profiles (casual, professional, technical, warm, blunt), context profiles and an optional house-style config shape the result.

A rewrite uses at most two editing passes. You get the final text plus a short verification note: passes used, which checks ran, findings left in place and why the agent stopped. The SKILL.md calls its patterns signals, not proof that a machine wrote the text.
