Claude writes its own parallel-agent prompt and nails the brief, screenshot goes viral

The author asked Claude to spin up a parallel agent, then inspected the prompt it wrote for itself — and called it "a legend".

The screenshot shows Claude proactively adding key context nobody asked for: the client is a demanding motion designer who rejects generic "slop", so craft matters — real reel physics (spin-up, a long fast blur, deceleration, slight overshoot past the stop, a settle back, a click/notch feel) and considered timing.

Takeaway: Claude autonomously packed persona, quality bar, and concrete physical parameters into the sub-agent's brief — a prompt-writing pattern worth stealing.
