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 221 sightings filed under Software Development on Agent Sightings (number 169 by interest), and one of 255 involving Claude Code.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.
Explain how <subsystem> works in this repo. Use explore subagents if helpful. Give me a short architecture note and the five files I should read first.
The prompt breaks down into 3 steps you can check as the agent works:
- Explain how <subsystem> works in this repo.
- Use explore subagents if helpful.
- Give me a short architecture note and the five files I should read first.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
