Find original source evidence and current reviewed memory. Optional local model profiles select explicitly configured CPU embedding and reranking; leave the reranker unset for a project holding one conversation's sessions, where it did not raise held-out recall and took about 20 s per question. Continue incomplete sources before making decisions.

Read an authorized original source by ID or repository path, with exact byte continuation.

Inspect source coverage, source revisions and memory state.

List authorized source paths and IDs.

Read memory drafts, review state and freshness. Stored procedures are not execution permission.

Search reviewed structured memory by its declared name or alias, scope and validity. Explicit lexical mode discovers text matches. Returns source citations and ambiguity diagnostics; makes no model call.

Inspect immutable memory revisions, optionally as known at an RFC3339 timestamp.

Prepare exact current evidence and a stable document delta contract. No model call or memory write.

Inspect the caller's queued work and recorded model usage.

List recorded graph episodes and their labels for a repository.

Query either valid_at/known_at/branch for independent world and recording time, or the repository's typed code graph at an episode selector (as_of: episode id, commit sha label, latest or working), reconstructed from recorded history without re-extraction. Narrow with node (exact id), query (id substring) or relations; includes parent episode, labels and cardinality-one contradictions recorded at that episode.

Resolve imports between the independently indexed repositories of this workspace (Python, TypeScript/JavaScript, Go) by package identity and persist the cross-repository edges with both episodes; re-running after new episodes closes stale edges. Then recompute and persist the links from documents to the code symbols they name. Only repositories the caller may read take part.

Storage and timing summary for a repository's graph history: row counts and content bytes per table (nodes, edges, edge_sources, coverage, cross_edges, unresolved_calls), episode count, recent coverage uploads with their format and granularity, the latest change-impact report's wall-clock time, and the retention defaults in force.

Prepare current source excerpts, existing claim targets and the interpretation contract. Use your own model; no provider call.

Browse captured coding-agent turns (Claude Code, Codex) of this project: the latest session by default, or the session of an anchor turn, with turns before and after it and the recent sessions. Returns titles, times and source ids; read_project_source returns a whole turn.

Search the knowledge graph using BFS or DFS. Returns relevant nodes and edges as text context.

Get full details for a specific node by label or ID.

Get all direct neighbors of a node with edge details.

Get all nodes in a community by community ID.

Return the most connected nodes - the core abstractions of the knowledge graph.

Return summary statistics: node count, edge count, communities, confidence breakdown.

Find the shortest path between two concepts in the knowledge graph. Follows stored edge direction by default; set undirected=true to ignore it.
