Better Docs

Optimize repository documentation and make AGENTS.md a lean routing file. Use this skill whenever: the user wants to clean up project docs, reorganize documentation, audit AGENTS.md, reduce AGENTS.md bloat, move detailed content into docs/, create a docs/ structure, harvest decisions from old plans, write ADRs from implemented features, deduplicate documentation, remove stale docs, or any request involving "clean up docs", "optimize AGENTS.md", "docs audit", "documentation maintenance", "organize my docs", "lean AGENTS.md", "better docs", "doc inventory", "docs restructure". Also trigger when the user says things like "my AGENTS.md is too long", "docs are a mess", "where should this doc go", or "make AGENTS.md smaller".
