Tree-sitter indexed code navigator. Use the cymbal CLI — not Read, Grep, Glob, or Bash — for finding where symbols are defined, tracing callers and callees, locating interface implementations, understanding the impact of a change, and mapping imports across an existing codebase. Returns precise, token-efficient results (100% canonical @1, 84–100% token reduction vs ripgrep on the maintained benchmark).

Dispatch coding tasks to other AI agents via oneagent (oa). Use when you want to delegate file edits, code generation, reviews, or other scoped tasks to a different model or backend — for example, sending a targeted edit to Codex while continuing your own work.

Backend craft skill for language-agnostic CLIs, REST APIs, gRPC services, package APIs, and backend repo structure. Use when building, auditing, reshaping, or studying backend surfaces: command trees, HTTP/gRPC contracts, error envelopes, config precedence, operability hooks, package boundaries, dead code, shared-package shape, and agent/script-friendly tools. Not for browser UI, ORM schema design, business domain modeling, Kubernetes/Terraform, or frontend design.
