The AI Bottleneck Isn't Generating Code — It's Governing It
Anyone who has given autonomous AI coding agents (Claude, Devin, Antigravity, or Copilot Workspace) free rein in a production repository knows the u…
The agent created a new file instead of editing the existing one. Now there are two.
The PR diff looks fine. You asked the agent to add a phone-number validator. It added a file called validation-helpers.ts with a clean, well-tested…
Ready to Make Your Web App Speak? No External TTS API Required
Your browser does more than run your app. It can give it a voice, too. Adding TTS (text-to-speech) capability to your web app doesn't necessarily re…
Your agent added a sleep() to fix a flaky test. It didn't fix anything.
The CI log shows a timeout. You send the failure to your agent. Two minutes later, it opens a PR: await new Promise(r => setTimeout(r, 500)) befo…
Your agent treats every TODO like it's blocking. Mark which ones aren't.
You leave a comment in the middle of a refactor: // TODO: cache this call for the list endpoint You meant: come back to this when the list page actu…
Your agent keeps deprecated aliases alive forever. Make it pick a cutover date.
The refactor PR looks clean. getUserById becomes fetchUserById , the body moves to a new service file, and the tests pass. At the bottom of the diff…
