EvalGate

0.90 min gate · 10-case suite

01 Problem

[problem: how prompt edits reached production untested, and what broke]

02 Approach

Prompt regression harness that gates every system prompt change against a fixed case set before deployment. Runs side-by-side Baseline vs. Candidate prompt diffs, enforces a strict minimum pass threshold (min = 0.90), and blocks CI builds when previously passing assertions regress.

03 Result

Prevented silent prompt regressions from reaching production by gating every system prompt edit against a deterministic 10-case evaluation suite (regex, exact label, and keyword contracts) with sub-2ms local verification.
