What problem does it solve?
It diagnoses “it ran but nothing happened” integration failures, where the expected side effect (hook, status update, callback, job, webhook, or outward call) is missing and there’s little or no error evidence.
Core Features & Use Cases
- Runtime-contract first tracing: Maps the concrete trigger → dispatch → receiver → observed outcome using file-and-line references so you can verify the seams are actually connected.
- Silent-failure pattern detection: Greps for swallowed errors and fail-soft constructs (like || true, empty catches, and output redirection) to surface the most likely “ran but got dropped” locations.
- Single fastest diagnostic request: Asks for one decisive piece of runtime evidence (or, if needed, the exact dashboard/log field) to disambiguate quickly, then ranks hypotheses with honest confidence.
Quick Start
Run fix-bug with mode=balanced and describe what action you took (and what side effect you expected but didn’t see), then paste the single most relevant runtime evidence you can provide (like the receiver log output while you reproduce).
