classmap-skill

Create, repair, and maintain CLASSMAP.md, a lightweight code responsibility map for a project. Use when onboarding to an existing codebase, when CLASSMAP.md is missing, stale, incomplete, or contradicts code, after major refactors, after adding important modules, or when the user asks to refresh the code map. This skill maps code ownership; do not use it to implement feature changes directly.

Use CLASSMAP.md to route feature requests, bug reports, refactors, and behavior changes to the smallest accurate set of relevant code units. Use before coding when the user asks where to change behavior, which class or file owns a feature, where a bug may live, or how to implement a change with minimal search. This skill may incrementally update CLASSMAP.md only for files inspected, changed, or created during the current task.
