AI-Assisted Code Review Needs Defined Stopping Rules to Avoid Endless Loops

An article on DEV Community highlights a common problem in AI-assisted code review: endless cycles of fixes leading to unclear final versions. The author argues this indicates a lack of defined stopping rules for the review process. They propose a practical pattern called 'one correction wave' to structure review, triage, and fixes coherently. This approach aims to make the review loop observable and provide a natural endpoint. The method emphasizes defining the scope of each review cycle based on new evidence, not merely re-running automated tools.

Developer's email validator flaw returns false trust score due to API error

A developer discovered a critical flaw in their own email validation service while testing 500 addresses on September 30, 2026. The system incorrectly returned a high deliverability score even when the breach-check component failed due to an invalid API key. The error resulted in the key "is_trusted_identity" field being null, while the overall score remained unaffected. This flaw could mislead API consumers into assuming an email address was trustworthy when its breach status was never verified. The validator, which checks syntax, MX records, and breach data, is available as open source and a hosted API.
