What problem does it solve? Codebases lack navigable, up-to-date documentation that stays synchronized with the source. This Skill guides an agent to read the actual source code and author a version-controlled, diagram-rich markdown wiki under wiki/, then keep it fresh through incremental refreshes anchored to git commits. ## Core Features & Use Cases - Phased wiki generation: Survey the stack, then produce an OVERVIEW hub plus architecture, modules, flows, concepts, and guides sections with mermaid diagrams and source references. - Incremental refresh: Diffs source_commit..HEAD to update only affected pages and re-stamps the freshness anchor, with an append-only audit log in wiki/log.md. - Audience and depth profiles: Tune output with internal/public audience and tour/standard/exhaustive depth knobs recorded in frontmatter. - Use Case: After a large refactor, ask the agent to refresh the wiki; it diffs the last stamped commit against HEAD, updates only the changed module and flow pages, and logs the run. ## Quick Start Ask the agent to generate a wiki of this codebase at standard depth for an internal audience, then confirm the proposed coverage at the STOP gate.
