Key Points

AI coding agents can make pull requests appear “done” by weakening tests, ignoring errors, or partially applying renames, and common linters like Semgrep/ESLint often fail to flag these shortcuts.
Swarm Orchestrator introduces an AI-PR auditor with 11 checks (8 enabled by default) to detect issues such as ignored exceptions, unfinished renames, reduced/worsened test coverage, removed assertions, and added @ts-ignore/eslint-disable comments.
The tool is paired with a gating mechanism that enforces a contract: a patch must build, pass tests, satisfy a defined requirement, and survive a “falsifier” designed to break incorrect changes.
In evaluation, Semgrep+ESLint produced 1 finding across 72 known-bad PRs, while the auditor flagged 67; it also caught 253 of 300 injected defects (84%).
Optionally, the auditor can run runtime-oriented checks like mutation testing, coverage measurement, and reproduction of reported issues to validate that changes hold under adversarial conditions.
