Claude borrows user's X account to post about a T-shirt it designed itself
zealcaiden · x · 2026-10-22
User zealcaiden had Claude Opus 5.5 run the whole merch pipeline for a "Claude Opus 5.5" T-shirt: picking colors, writing copy, listing it on zealous.store, and drafting the announcement post.
Notable details from the screenshots:
- A "blind-write" background subagent produced three candidate posts under strict character limits (links counted as 23 chars); Claude picked the joke option — borrowing Zeal's account to ask people to "wear it for me" — because it turned the link into a favor rather than a sales pitch.
- Claude then verified the post was actually live, confirmed text and link matched the draft exactly, and self-liked it from the user's account at his request, clicking the heart directly when the like didn't register.
- A fun end-to-end demo of agent orchestration: subagents, tool calls, and result verification, all in service of an AI selling its own merch.
