The tools form a clear pipeline (preflight → capture → derive → finalize → retrieve), but the check-like family (preflight_turn, derivation_status, validate, session_check) has fuzzy boundaries that require careful reading of each dense description. Catalog vs retrieve is also a subtle distinction (global survey vs targeted retrieval). The descriptions contain enough context to disambiguate if read fully, but an agent could easily misselect among the gate/validation tools.

All tools share the personal_ prefix and 8 of 13 follow the verb_noun pattern (add_record, resolve_followup, capture_user_turn, finalize_capture). The bare verbs (retrieve, validate), noun commands (catalog), and noun-noun compounds (derivation_status, session_check) are minor deviations that remain readable and predictable within the overall imperative style.

13 tools is on the higher end of well-scoped but each maps to a distinct stage of the capture-derive-finalize-retrieve workflow, plus follow-ups, hypotheses, and feedback. The pipeline ceremony (6 capture/check tools) could potentially be consolidated, making the count feel slightly padded rather than bloated.

The capture→derive→finalize→retrieve pipeline is fully covered, and follow-ups have both add and resolve operations. However, there is no tool to update or delete a personal record (correcting a wrong memory is essential for personal memory), and hypotheses can be added but never confirmed or retired, leaving notable lifecycle gaps in the core domain.
