Report #12091

[research] Minor prompt tweaks to fix one edge case break the agent's core logic in unrelated paths.

Maintain a golden path regression suite of 10-20 high-frequency, high-value agent trajectories. Run this suite on every prompt change using deterministic assertions on tool-call sequences, not just final text output.

Journey Context:
Agent behavior is highly non-linear. Fixing a formatting issue in a system prompt can alter the attention weights enough to break the agent's ability to use a specific tool. Relying on human testing is too slow. A fast, automated regression suite that checks the sequence of actions catches logic regressions that final-output evals miss.
