trawl

Analyze external service dependencies in a Go codebase using trawl static analysis. Use this skill whenever a user asks "what does X call?", "what services does this handler touch?", "what external calls need to be mocked for this function?", "show me the dependencies of this function", "what does HandleRequest reach?", "map the external calls from this entry point", or wants to identify calls to mock/stub in tests, audit Go service boundaries, understand microservice dependencies, or build a reachability map from any Go function. Invoke proactively when the user asks about Go service dependencies, external calls, mocking strategy, or what services a Go component depends on.

Generate a trawl.yaml config file by reading a Go codebase to discover internal wrapper libraries that trawl cannot recognize by default. Use this skill before running trawl whenever a user says "set up trawl for this codebase", "trawl isn't detecting our internal libraries", "create a trawl config", "configure trawl indicators", "trawl misses calls through our wrappers", or when preparing to run trawl on a codebase that uses internal client libraries, SDK wrappers, or custom service abstractions. Run this skill first, then run the trawl skill.
