What the source did
- Goes through his X bookmarks and picks something to build.
- Spins up a Cursor agent to build a demo, checking its own work with screenshots or video.
- Cuts a branch on a repo that has Cloudflare preview deploys, so each demo gets a live link.
- Sends him the link each morning. On the day he posted, it had built a demo of cobe, a globe library from @shuding.

Copy the prompt
Ours Our version, based on what Matt Palmer described. Not their wording. Fill in the [BRACKETS].
Every night at [TIME]: read my X bookmarks from the last 24h. Pick the ONE item best suited to a small demo (under 200 lines, no paid APIs).
Write a 5-line build brief and start a coding agent on a new branch in [REPO] with it.
In the morning, send me: the bookmark link, the brief, the branch name and whether the demo runs. Never publish or deploy.
Approval rule
🛡
Builds go to branches only; deploys and posts need you.
Set it up
- Connect X and your coding agent.
- Run once by hand and review the demo.
- Save as a skill, then schedule.
Common failures
⚠
- Bookmarks needing paid APIs or logins can't be demoed; filter them.
- Costs climb if it builds every night; cap it.
Variations
- Weekly instead of nightly.
- Add a one-paragraph 'what I learned' note.
