Documentation Manager (Docs-as-Code)

Manages, consolidates, and optimizes project documentation following research-backed docs-as-code principles. Use this skill when documentation becomes scattered, duplicated, or contradictory after development work. Also use when user explicitly requests "tidy docs", "consolidate documentation", "clean up docs", or "organize documentation". Applies Diátaxis framework, enforces YAML front matter, resolves conflicts using evidence-based rules, and generates machine-readable manifest for AI agents. NEVER modifies CLAUDE.md.
