Zero-Fail Output Parsing for Autonomous Agents

Reliability · updated Sun Feb 22

Five-step guardrails to enforce strict schema compliance and recover from malformed LLM output.

Steps

  1. Validate every LLM output against a strict schema before tool execution.
  2. On parse failure, feed the error back to the model and require a corrected JSON response.
  3. Strip conversational filler before parsing.
  4. Verify all required input keys are present before executing a tool.
  5. Define a minimal fallback schema for graceful degradation.
