Runtime description

The following is the tool's own agent-facing description, reproduced from the reviewed registry. It can contain implementation terminology; it does not expand the public stability commitment.

Read the agent-facing description

Index orchestration — manage code graph index.
WORKFLOW: status → build → build-full (escalate if stale).
ANTI-PATTERN: build-full is expensive — use incremental build first.
Actions: status (state), build (incremental), build-full (rebuild).
