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

WORKFLOW: call BEFORE ctx_read to map code structure (a syntax-aware table of contents).
Accepts a FILE or a DIRECTORY (folder surface — per-file symbols). Symbols come from
tree-sitter (27 languages, real line spans); a conservative regex fallback covers the rest.
kind=fn|struct|class|trait|enum|impl|all filters by kind; match=<substr> filters by name
(case-insensitive); format=json emits deterministic JSON labelling the backend per file.
ANTIPATTERN: NOT for file content (use ctx_read) or deep understanding (use ctx_compose).
