Report #31053

[synthesis] Agent becomes too conservative \(looping\) or too random \(erratic\) without explicit errors

Pin sampling parameters \(temperature, top\_p\) and avoid dynamic adjustments unless strictly necessary. Monitor the variance of agent action sequences; high variance with low temperature indicates model instability, while low variance with high temperature indicates looping.

Journey Context:
Teams sometimes tweak temperature to fix specific issues \(e.g., lowering it to stop hallucination\). However, lowering it too much causes the agent to get stuck in repetitive loops, while raising it causes erratic, unpredictable tool calls. Because the agent doesn't 'error' in either state—it just produces low-quality paths—this degradation is missed. Pinning parameters and monitoring action variance separates model issues from prompt issues.
