What happened
On PR #2429, the review agent approved 3 times (2026-06-18 twice, 2026-06-23 once) with no findings. The PR modified Containerfile base image tags but did not include the required lockfile regeneration. The repo's CLAUDE.md explicitly documents this requirement under 'Diagnosing Stale Lockfiles': when Containerfiles change base images, rpms.lock.yaml must be regenerated. The review agent did not flag this gap despite having access to CLAUDE.md.
What could go better
The review agent presumably reads CLAUDE.md but did not apply the documented constraint that base image changes require lockfile regeneration. This is a cross-file impact analysis gap — the agent saw Containerfile changes in isolation and approved without checking whether companion file changes were needed. Existing upstream issues #2151 (consult Makefile/build targets) and #1525 (cross-file impact analysis) partially overlap, but neither specifically addresses the pattern of 'CLAUDE.md documents that change X requires companion change Y, and the review should verify Y is present.' Confidence is moderate — the review agent may have read CLAUDE.md and decided the lockfile concern was out of scope for a review comment. But given the PR sat broken for 15 days, flagging the missing lockfiles would have been high-value.
Proposed change
Enhance the review agent's dependency-update review path to extract actionable constraints from CLAUDE.md and verify them against the PR diff. Specifically:
- When reviewing a PR that modifies build-related files (Containerfiles, Dockerfiles, package manifests), the review agent should check CLAUDE.md for documented post-change requirements.
- If CLAUDE.md states that a certain file change requires a companion change (e.g., 'if the Containerfile changes, regenerate lockfiles'), the agent should verify whether the companion change is present in the PR diff.
- If the companion change is missing, the agent should flag it as a finding rather than approving.
This could be implemented as a pre-review checklist step in the review agent's prompt or as a dedicated sub-agent that extracts build constraints from CLAUDE.md.
Validation criteria
On the next 3 dependency-update PRs in repos with documented companion-change requirements in CLAUDE.md, the review agent should either: (a) flag missing companion changes as a finding, or (b) explicitly note in its review that companion changes appear to be present. Zero false-negative approvals on PRs with clearly documented missing companion changes.
