The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · b5d6f8f

Ran it on a paragraph stuffed with 'pivotal moment', a challenges-formula close, and a negative parallelism: the skill named all five clustered signals by category (not just 'sounds AI'), where an unguided read only produced a vibe judgment.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Wikipedia Not AI does

A static analysis checklist (no code, no external calls) for spotting AI-generated prose: vocabulary density, significance inflation, decorative triplets, drumroll-in-disguise connectives, and more, weighted by cluster density rather than single hits. Trigger it with 'check this text for AI tells', 'audit this email/report for AI markers', or 'clean up this AI-sounding draft'.
