Generates comprehensive architecture documentation for code changes, PRs, and implementation phases. Use this skill whenever the user asks to document code changes, write an architecture doc, create a technical reference, or help a human reviewer understand what a coding agent built. Trigger on phrases like "arch doc", "architecture doc", "document this PR", "write arch doc for phase X", "generate a living reference", "document these changes", "/arch-doc". This is especially valuable after a coding agent completes a feature or phase — the document helps a human reviewer understand, audit, and manually verify the work before merging.
