Use when public prose still sounds machine-written after ai-tells-scan. Complements ai-tells-scan's mechanical pass with structural judgment: rhythm, hedging, rhetorical reflexes, and performative emphasis. Trigger on 'review for AI tells,' 'does this read AI,' 'strip the AI smell,' or 'make this less AI.'.

Use when filing, updating, sequencing, or querying tasks in any atlas-crew repo (Facet + the Atlas Crew Security repos: Apparatus, Chimera, Crucible, Synapse, Bridge). These repos track work in GitHub Issues on Projects v2 boards, NOT backlog.md. Covers the two boards, the Type/Area/Status field model, cross-repo…
Skill Claude CodeCodex
Use this skill when a working tree contains uncommitted changes that need to be split into a sequence of atomic commits — typically after a long session, an agent hand-off, a rebase resolution, or anytime git status shows mixed work that was not committed as it landed. The skill assumes the agent has fresh context and…
