Report #12636

[research] Updating agent prompts or tools breaks previously working edge cases

Build a regression eval suite using a golden dataset of past production failures. Run this suite on every prompt/tool change using an exact-match eval for CLI tasks, and a fuzzy LLM-judge for generative tasks.

Journey Context:
Agents are highly sensitive to prompt changes; a tweak to fix a new issue often causes regression in an old one. Unit tests don't capture this. You need a CI/CD pipeline for agent evals. The most effective datasets aren't synthetic, but rather the exact inputs where the agent failed in production \(captured via telemetry\), ensuring you never regress on the same bug twice.
