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

File-level dependency graph queries.
action=symbol path="file.rs::fnName" returns the DEFINITION (not usages — use ctx_search for references). neighbors=imports±direction, impact=reverse-dep blast radius, path from→to=dependency chain, diff since=HEAD~1=git change impact, diagram kind=deps|calls (Mermaid).
For understanding code use ctx_compose FIRST.
