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

Callers/callees for one symbol (function call edges, not const/var refs).
action=callers|callees symbol='fn' → every call site with file:line.
action=trace from→to finds the path between two symbols (depth=N).
For end-to-end flow understanding use ctx_compose FIRST.
