> De-AI writing at the layer that actually gives AI away. Fiction gets its narrative architecture repaired before anyone touches word choice; professional documents (release notes, PR replies, postmortems, tickets, technical articles) each get rules matched to their venue.

A portable [Agent Skill](https://agentskills.io/specification): any agent that speaks the standard can load it, and the [Skills CLI](https://skills.sh), which supports 77+ agents, installs it with one command. Claude Code, Codex, Grok Build, Antigravity, and QwenPaw additionally get native plugin packaging. One canonical `SKILL.md`, no per-platform forks. Four operations: **write**, **review** (diagnose only), **refactor** (minimal edits), **recreate** (full rewrite).
