[research] Agent silently degrades over time without throwing exceptions
Implement periodic golden-set regression testing against a frozen dataset of expected tool-call traces, comparing exact tool invocation sequences and arguments rather than just final text output.
Journey Context:
Agents often fail silently because LLM outputs remain valid JSON but represent a suboptimal or incorrect action path. Standard exception monitoring misses this. By diffing the actual tool trace against the golden trace, you catch logical drift before it impacts downstream metrics. Text-output evals are too forgiving; structural trace diffs are strict where it matters.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
