AI Catches Its Own UI Side-Effect via Screenshot Verification Before Opening PR

DanielLockyer · x · 2026-10-07

Developer Daniel Lockyer shares a concrete example of AI coding with verification tooling: asked to make a UI change, the AI edited the code, ran screenshot verification, spotted an unintended side-effect, fixed it, and opened a PR with before/after diffs. Without the tooling, the bug would have surfaced only after he noticed and reported it back. His takeaway: vanilla AI plus verification beats most skill packs.
