What problem does it solve?
Teams running LLM agents in production often don't know what to fix next. This Skill mines real production traces and analytics for failure patterns, forms explicit evidence-backed hypotheses, and executes the chosen ones as scenario tests, prompt or code changes in reviewable PRs, evaluators, monitors, and experiments.
Core Features & Use Cases
- Evidence-driven diagnosis: Queries LangWatch analytics and exports traces to find failure clusters, cost concentration, and quality trends before proposing anything.
- Hypothesis workflow: Presents 2-4 ranked hypotheses with observation, suspected cause, proposed test, fix, and expected metric impact, then waits for user approval before executing.
- Concrete execution: Reproduces real failures as scenario tests (with sanitized inputs), ships prompt/code fixes as PRs, adds evaluators and monitors, and runs experiments to settle competing approaches.
- Use Case: Your support agent mishandles date-sensitive questions in production. The Skill finds the failing traces, hypothesizes stale retrieval, writes a scenario test reproducing the failure, fixes the retrieval code on a branch, and opens a PR linking the evidence.
Quick Start
Ask the agent to analyze my LangWatch production traces and tell me what I should do next to improve my agent.
