List every top-level symbol (with its range) defined in path within repo.

Resolve symbol's definition location(s) within repo.

Every occurrence of symbol within repo, definition sites included.

Single-level incoming/outgoing call hierarchy for symbol within repo.

Single-level super/subtypes for symbol within repo.

Returns an explicit error when the index carries no relationship data —
`scip expt-convert` does not populate `global_symbols.relationships`, so
an empty result would wrongly imply the symbol has no supertypes.

Whether repo has a published index, and its freshness. Pass repo_path (the repo's local git working directory) to compare the published commit against git rev-parse HEAD; omitted, freshness is reported without a staleness comparison.

Lexical code search via an embedded Zoekt index (lazy-started on first call). repo, if given, is applied as a Zoekt r: query filter scoping results to that one indexed repo; omitted, results span every indexed repo.

Natural-language code search over repo: embeds query, retrieves top vector matches from the repo's semantic index, fuses them with Zoekt lexical hits via reciprocal rank fusion. Requires the repo to have been indexed with the semantic extra installed.

2-hop bounded BFS over the package dependency graph: every other indexed repo whose package directly (1 hop) or transitively through one intermediary (2 hops) depends on symbol_or_package as registered for repo (built by codeintel index, e.g. "npm:@scope/name"). The graph has no per-node timestamp, so freshness is always reported as unknown here — an honest limitation, not a bug.
