The need
Prompt changes were being reviewed by intuition. The team needed a shared way to run the same cases, preserve results, and inspect regressions.
- Versioned datasets
- Comparable model settings
- Human review alongside automated scores
Implementation
Runs are immutable records tied to dataset and prompt versions. A worker pool executes cases and streams partial results to the comparison interface.
- Provider-neutral adapters
- Retry-aware execution
- Segment-level score breakdowns
Result
Prompt review became an engineering workflow with evidence instead of a collection of screenshots and anecdotes.
