He had Claude Code build his own: one message ('new build is live, test it! FR / EN') makes an old Mac start 2 iPhone simulators, create and pair 2 accounts, play the quiz on both sides, check the partner sees it, and send a report to Slack.https://useagentsfor.pages.dev/use-cases/build-a-two-phone-test-robot-for-a-couples-app-instead-of-paying-500-month/https://useagentsfor.pages.dev/use-cases/fix-a-broken-website-button-with-a-custom-browser-extension/The 'Open in GitHub Desktop' button the user relied on for years stopped working. He asked Codex to triage it: Codex confirmed it was a real bug on the website, then wrote and installed a custom extension that fixed it, all in under a minute.https://useagentsfor.pages.dev/use-cases/fix-a-broken-website-button-with-a-custom-browser-extension/https://useagentsfor.pages.dev/use-cases/build-a-dead-man-s-switch-so-your-clients-aren-t-stranded/After losing his business during a 2012 hospital stay, web developer Peter Bishop wrote a detailed spec and had Claude Code build Death Plan Switch, a self-hosted, MIT-licensed dead man's switch that tells the right people if he goes missing or dies, so his business can keep running for his clients. It passed 42 unit tests and he has used it for weeks.https://useagentsfor.pages.dev/use-cases/build-a-dead-man-s-switch-so-your-clients-aren-t-stranded/https://useagentsfor.pages.dev/use-cases/win-the-race-for-parent-teacher-conference-slots/Elizabeth Knopf's agent (Dots) watched for the school's sign-up email, with her family calendars and time preferences already connected. When the email came, it booked her priority parent-teacher slots on SignUpGenius and saved the calendar invites while she was on a call, before the convenient times were gone.https://useagentsfor.pages.dev/use-cases/win-the-race-for-parent-teacher-conference-slots/https://useagentsfor.pages.dev/use-cases/audit-whether-your-24-7-agent-is-really-running-it-mostly-slept/A user asked Claude Code to audit Richi, his '24/7 autonomous' crypto agent running on Hermes on a Mac mini and controlled over Telegram. The first line of the verdict: full autonomy is not verified. The Mac had gone to sleep 31 times in 20 hours 43 minutes, so the agent was mostly asleep.https://useagentsfor.pages.dev/use-cases/audit-whether-your-24-7-agent-is-really-running-it-mostly-slept/https://useagentsfor.pages.dev/use-cases/get-roadside-help-abroad-when-you-can-t-speak-the-language/Stranded with a broken-down car on a German Autobahn and unable to follow the insurer's German-only phone line, the user asked Grok Bot to handle it.

After 24 hours, 332 had barely moved, 202 were down, 28 had lost over 90% and 31 were up (best 8.3x, none 10x).
