Search through past Claude Code conversations across all projects. Use when the user asks about previous discussions, past decisions, or anything from a prior conversation.

Retrieve more conversation context around a specific search result. Use ONLY after calling search, when you need to see what was discussed before or after a result.

Update the search index with recent Claude Code sessions. Call if search returns stale results or the user asks to refresh the index. Modes: 'incremental' (default, only new/changed), 'full' (delete all and rebuild from scratch), 'cancel' (stop running index).

List all indexed Claude Code sessions. Use when the user wants to browse conversation history or find sessions by project/date.

Manage which projects are registered for indexing. Use 'list' to see all projects on disk and their registration status. Use 'add' to register a project for indexing. Use 'remove' to unregister. Projects must be registered before they can be indexed.

Check the health and progress of lore indexing. Shows indexing status, session counts, DB size. Use this to monitor indexing progress after calling index.
