Each tool has a clearly distinct purpose: alias resolution, initialization, capturing fleeting notes, writing permanent notes, updating, reading, searching, linking, listing packs, health checking, home refresh, nightly maintenance, and audit. No two tools overlap in functionality.

All tools use the 'zero_' prefix, but the naming pattern is inconsistent: some are verb_noun (e.g., zero_write_note, zero_update_note, zero_list_packs) while others are single verbs (e.g., zero_init, zero_capture, zero_read, zero_search, zero_link, zero_health, zero_home, zero_nightly, zero_audit). This mix of styles reduces predictability.

13 tools is well-scoped for a personal knowledge management system. Each tool serves a necessary function for note-taking, linking, searching, and system maintenance without overwhelming the agent.

The tool surface covers core CRUD operations (create via write_note/capture, read, update, search) plus linking and maintenance. The only notable gap is the absence of a delete note tool, which may be intentional but limits full lifecycle coverage.
