doc-standards-skill

Documentation writing-quality standards — controlled language (ASD-STE100), Google/Microsoft style guide rules, ISO 24495 plain language, AI/agent readability (llms.txt, self-contained sections), and a machine-checkable lint gate. Use whenever writing or reviewing ANY documentation prose — README, API reference, tutorial, how-to, changelog, error message, code comment blocks, llms.txt — even if the user only says "write docs", "document this", "improve the README", "docs smell like AI", or "make the docs clearer". Structure/coverage questions (which doc types exist) belong to a Diátaxis-structure skill if one is installed; THIS skill governs how each sentence and section is written, and provides the lint gate to verify it.
