Prompt Edit Confidence From Trace Coverage Not Benchmark Scores
Production traces reveal confidence in prompt edits that benchmarks cannot.

Gating Agent Deploys on Replay Pass Rates From Production Trace Snapshots
Replay-based gates catch silent agent quality regressions that standard monitoring misses.
Sonja Ketterer
Judge Model Selection for Automated Replay Evaluation
Replay catches failures, but only a well-chosen judge can score them.

Historical Trace Validation Before Shipping Agent Fixes
Replaying fixes against real failure traces catches what tests miss.

Wiring Replay Evals Into a CI/CD Pipeline for LLM Agents
Replay evals freeze production traces so you can test one fix live.

Replay Eval Coverage Metrics for Agent Harness Changes
Replay coverage means testing known failures, not code lines.

Determinism Controls in Agent Replay Environments
Temperature zero can't make agents repeatable, but layered recording can.

Trace Corpus Curation for Replay Eval Suites
Replay test suites need carefully curated traces, not just volume.
