triggerdotdev/agentcrumbs

Agents write inline trace statements marked with `@crumbs` comments that emit structured events to a local collector, then query those traces via CLI to debug failures—the collector aggregates multi-service traces over HTTP with zero dependencies. Before merge, `agentcrumbs strip` removes all trace code via AST-based marker detection, while noop functions ensure traced code has negligible overhead when disabled. Integrates with TanStack Intent skills to teach agents when and how to instrument code, with cross-language support via HTTP POST and browser/Node.js dual builds.
