Tools & Capabilities Breakdown

Memory Tools (9)

zhiji_workspace_assemble

Flagship.** One call returns everything needed to understand this user for a query — relevant memories + profile + confirmed facts + behavioral inferences (plus counterfactual & cross-domain hints). Drop straight into any LLM's context.

zhiji_memory_search

Lighter, recall-only: the 11-stage hybrid pipeline (trigram FTS + semantic + time-decay), returns scored snippets with sources.

zhiji_profile_get

7-layer / 37-dim user profile as an inject-ready natural-language summary.

zhiji_facts_get

Structured atomic facts (subject attribution, confidence, conflict status) — for exact names/dates/counts, not narrative.

zhiji_prospective_due

Due/upcoming intentions (todos, promises, plans) within a time window — for proactively nudging the user.
