[research] Updating the agent's system prompt fixes one edge case but breaks core capabilities

Maintain a version-controlled golden dataset of input-output-trajectory triples. Run this regression suite automatically on every PR that modifies the system prompt or tool definitions, using an LLM-as-a-judge to compare the new trajectory against the golden one.

Journey Context:
Prompt engineering is highly non-linear. Fixing a specific failure often introduces regressions. Relying on manual testing is unsustainable. A regression suite ensures that prompt changes are additive, though it requires an initial investment to curate the dataset and define the judging rubric.
