Why it matters

Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 12 by interest), and one of 30 involving Cursor.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Cursor or any similar agent and adjust the details to your situation.

Map this iOS feature into bite-size prompts. Implement the next slice on a branch with tests. Stop when you hit a multi-layer integration (push, CloudKit, payments) and list what needs a human.

Copy prompt

The prompt breaks down into 3 steps you can check as the agent works:

1. Map this iOS feature into bite-size prompts.
2. Implement the next slice on a branch with tests.
3. Stop when you hit a multi-layer integration (push, CloudKit, payments) and list what needs a human.
