Papaya

Improvement platform for production AI agents: it reads an agent's traces and code, finds the fixes behind quality, latency and cost problems, ranks each by its impact and can open the fix as a pull request, with automatic use-case detection, user signals from real conversations, an automatically built evaluation rubric and Slack alerts.
