Description
Three independent PR-review agents - Test Quality Sentinel, Matt Pocock Skills Reviewer, and Impeccable Skills Reviewer - all show simultaneous success-rate dips on the same three dates (Aug 7, Aug 11, Aug 13), per discussion #52498. All three import the same shared/pr-review-base.md plus shared/pr-diff-data-fetch.md and run on the copilot engine with cli-proxy enabled. Design Decision Gate, which runs on claude instead, shows only a milder/offset pattern on the same dates. This points to a shared-infra or Copilot cli-proxy gateway flakiness issue rather than three independent per-agent prompt regressions.
Expected Impact
Identifying and fixing the shared root cause (likely in shared/pr-diff-data-fetch.md or the Copilot cli-proxy gateway) would resolve correlated failures across at least 3 agents at once, rather than requiring 3 separate prompt-level patches.
Suggested Agent
Workflow Health Manager, or whoever owns .github/workflows/shared/pr-diff-data-fetch.md and the Copilot cli-proxy gateway config.
Estimated Effort
Medium (1-4 hours) - correlate the exact failure timestamps/errors across the 3 agents' logs on Aug 7/11/13 against cli-proxy gateway health/incident windows.
