faq-mine
Mine docs/faq.md from README.md, docs/*.md, AND the pi-hermes memory stores (project MEMORY.md + global failures.md). Dispatches @fast subagents per source to extract recurring how-to / what-is questions and runtime-problem fixes, dedupes against existing FAQ, and merges entries in caveman style. Use when the user asks to "build / regenerate / extend the FAQ", "mine docs into FAQ", "mine hermes memory into FAQ", "surface runtime problems in the FAQ", "create FAQ from README + docs", or "process knowledge into faq.md".
