Tools

• memory_recall Find scoped memories with this memory's configured retrieval (by default hybrid when the local embedding model is available, otherwise lexical). Corrections and provenance restrictions apply to every result.
• memory_context Compile cited, scoped context with contradictions and abstention under a conservative byte-based token budget. Pass only packet.text as context; diagnostics are outside the budget.
• memory_inspect Inspect accessible stored evidence and its lifecycle. Inactive records are history, not current advice.
• memory_resume Read the latest accessible active checkpoint for a task. Completed steps and artifact paths are historical claims. Verify current environment and permissions before acting.
• memory_source Read a bounded UTF-8 range of the original captured transcript or extracted document. Its status and trust remain visible.
• memory_model Inspect a source-backed project model. Stale models are marked and must not be treated as current knowledge.
• memory_skill Inspect a reusable skill and its prerequisites, trial evidence and current eligibility. This does not execute the skill.
• memory_jobs Inspect bounded observation/consolidation jobs and their outcome. Only the host executes configured model workers.
• memory_entity Resolve an entity name or alias without silently merging ambiguous identities.
• memory_traverse Follow a bounded number of evidence-backed relationship hops; each hop retains source IDs.
• memory_branch_preview Inspect isolated proposed changes and source conflicts before a controller merges them.
• memory_store Record an observed fact, preference, decision or procedure with a source. Private by default; workspace visibility explicitly shares with this workspace. Agent notes cannot self-certify as verified. Similar text is never automatically merge
• memory_capture Capture supplied transcript events with stable retry IDs. This reads no host files. Observed messages remain fallible evidence.
• memory_observe Queue source-linked observations or a project model for the host to process under its configured model and budget. This does not invoke or choose a model.
• memory_checkpoint Save a resumable task state, preserving constraints, rejected approaches and unfinished work. It does not perform or authorize actions.
• memory_correct Explicitly supersede your own non-verified observation; dependent advice becomes invalid. Controller-verified evidence must be corrected through the controller SDK.
