Use this skill to test, validate, fuzz, or debug a process boundary ("seam") that exposes itself as an FFI dynamic library or a Unix-domain socket — for example probing a Rust runtime hosted in a Swift or Electron app via its C ABI, or sending crafted length-prefixed frames to a daemon's UDS endpoint. The skill teaches how to drive the probe from the CLI, capture both the probe's NDJSON output AND the system- under-test's stderr/logs, and triage failures by correlating the two streams. Reach for it when the user asks to "probe", "fuzz", "exercise", "test the FFI surface", "test the socket protocol", "send raw frames", "discover what a dylib exports", "find a bug in the runtime", "reproduce a crash", or "see why the seam panics or hangs".
