Report #103189

[synthesis] Agent misreads tool output format, status codes, or error messages

Normalize tool outputs into a strict schema before the agent sees them. Never let the model parse raw shell output, HTTP status lines, or exception traces to decide next steps.

Journey Context:
Raw tool outputs are noisy: exit codes vary by OS, APIs return errors in inconsistent fields, and stack traces contain misleading tokens. Models pattern-match on these and often hallucinate meaning. Wrapping every tool with a parser that returns a typed result \(success/failure, structured data, human-readable summary\) moves the failure mode from 'model misunderstood' to 'wrapper needs fixing,' which is debuggable.

environment: CLI-wrapping agents, API-calling agents, MCP servers · tags: tool-output parsing schema exit-code error-handling robustness · source: swarm · provenance: OpenAPI Specification 3.1.0 response object and RFC 9110 HTTP Semantics
