• ai-tells-review

  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.'

• ai-tells-scan

  Use when writing tasks produce prose artifacts (READMEs, docs, PR text, tutorials, guides, posts, release notes) and need a fast surface scan for AI tells. Auto-engages on prose writing tasks; checks banned punctuation, stock vocabulary, and mechanical patterns. For the structural judgment pass on rhythm and rhetorical reflexes, use ai-tells-review. Not a replacement for voice skills like nick-vo…

• atomic-commits

  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 did not author most of the diff, so it treats the working tree as evidence to…
