Monday Service reveals eval-driven development framework that cut AI agent testing from 162 seconds to 18 seconds using LangSmith and parallel processing.

Monday.com’s enterprise service division has slashed AI agent evaluation time by 8.7x after implementing a code-first testing framework built on LangSmith, cutting feedback loops from 162 seconds to just 18 seconds per test cycle. The technical deep-dive, published February 18, 2026, details how the monday Service team embedded evaluation protocols into their AI development process from day one rather than treating quality checks as an afterthought. Why This Matters for Enterprise AI Monday Service builds AI agents that handle customer support tickets across IT, HR, and legal departments. These agents use LangGraph-based ReAct architecture—essentially AI that reasons through problems step by step before acting. The catch? Each reasoning step depends on the previous one, so a small error early in the chain can cascade into completely wrong outputs. “A minor deviation in a prompt or a tool-call result can cascade into a significantly different—and potentially incorrect—outcome,” the team explained. Traditional post-deployment testing wasn’t catching these issues fast enough. The Technical Stack The framework runs on two parallel tracks. Offline evaluations function like unit tests, running agents against curated datasets to verify core logic before code ships. Online evaluations monitor production traffic in real-time, scoring entire conversation threads rather than individual responses. The speed gains came from parallelizing test execution. By distributing workloads across multiple CPU cores while simultaneously firing off LLM evaluation calls concurrently, the team eliminated the bottleneck that had been forcing developers to choose between thorough testing and shipping velocity. Benchmarks on a MacBook Pro M3 showed sequential testing took 162 seconds for 20 test tickets. Concurrent-only execution dropped that to 39…
