Developer builds CI for prompts to catch regressions

By PulseAugur Editorial · [1 sources] ·

The developer built Sentinel, a prompt regression gate for CI, to address issues in prompt testing. Sentinel runs evaluation suites on prompt changes, accounting for run-to-run noise to prevent regressions before merging. The system was developed for the Agent Harness Hackathon and utilizes tools like TrueForge and Sandbox for tasks such as PR management and assertion generation. Challenges encountered included prompt judges being unable to see submissions, issues with temperature settings on models like Claude Sonnet-5, and GPT-4o mini returning inconsistent results. AI
