UnverifiedFailure modes (e.g., {"error": ...}) should be explicitly defined and validated at the code layer, transforming drift from silent wrong answers into catchable exceptions.80% similarUnverifiedFailure records in OpenAmer's ledger include a why field that categorizes failure reasons into human-readable information, such as task timeout, tool returning an unexpected data structure, path not reaching the objective, missing dependencies, etc.79% similarUnverifiedMisreporting tool execution errors as protocol errors causes the model to miss useful hint information and be unable to self-correct, causing the agent to stop or enter an infinite loop.78% similarUnverifiedWhen a tool returns an error or empty output, it should be rejected immediately rather than passing on incomplete data — this is a fail-fast handling approach77% similarUnverifiedThe tool should return a clear error message upon blocking (such as "all proxy nodes are currently rate-limited by the target host"), letting the LLM treat the failure as an unrecoverable state and thus switch strategies rather than retry.77% similar
