“This afternoon Claude code diagnosed an issue I’ve had with my 4K displays since Tahoe, it would have taken me a week just to learn enough to try to figure it out.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
They asked Claude Code to look into a 4K display bug they’d had since upgrading to Tahoe. Claude Code diagnosed the issue and built a CLI tool that fixes it. They also set up a weekly report that tracks Chezmoi configuration drift across all their machines.
How it went
Figuring out the display bug themselves would have taken about a week of learning; Claude Code diagnosed it the same afternoon. Setting up the Chezmoi drift report took 30 minutes.
Try it yourself with Claude Code
Describe a recurring bug or annoyance on your computer to Claude Code, including the exact steps that trigger it and relevant system details like your OS version. Ask it to diagnose the root cause and build a small CLI tool that fixes it for good. Once that works, ask it to also set up a scheduled report, for example with Chezmoi, that flags configuration drift across your machines.
A starting prompt written by Agents in the Wild. Fill in the [brackets], and check what the agent does before it sends, pays for or deletes anything.
WhatsApp has no native way to schedule messages, and the writer didn't want third-party apps in their chats. Claude Code built a scheduler using a headless browser, and a recurring message now goes out every morning.
A recorded rapid chess game came with a voice memo of what the player was thinking move by move. Claude drove Stockfish to question each thought and built a narrated video explaining the mistakes.
One message from a phone through Claude Code's Dispatch: boot World of Warcraft and log in to a specific character. Claude Code opened Battle.net, launched the game, waited out the login and picked the character.
They never had the time or energy for the backlog. Claude Code writes small, deterministic programs that do the work, and most of the scripts they'd wanted for years now exist.
Always-on agents are overkill for a schedule. Claude Code built a plain script that pulls listings from open APIs into a database; when enough pile up, Claude Code finds the ones that fit.
Onboarding onto a new project means a stream of unstructured thoughts. They dictate them, and Claude Code tags and links everything in Obsidian. Weeks later, "What did I do yesterday?" just works.
