agent eval latency added 18 minutes to our CI. how are you running this without killing dev velocity?

Summary

A discussion on the challenge of integrating comprehensive agent evaluations into CI, where latency from judge calls increases build time from 6 to 24 minutes, and potential solutions like parallelization, caching, and async eval are considered.

agent + langgraph + ~7 tools. added comprehensive eval to CI as a blocking gate. p99 build time jumped from 6min to 24min. judge calls dominate (~200 scenarios × 2 samples). engineers are batching changes to avoid the gate. defeats CD entirely. tried: parallelize judge calls (5x speedup, 429 risk) semantic caching on unchanged scenarios (~60% hit rate, cache invalidation pain) lighter eval on PR, heavy eval nightly async eval post-deploy with canary rollback leaning toward 4 but worried about action-taking agent shipping briefly-broken state. how are people structuring this?
