CocoIndex

This skill should be used when code search, file/directory summary lookup, or concept-guide lookup is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'describe this file', 'read the concept guide', 'update the index', 'ccc', 'cocoindex-code'.
