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 186 by interest), and one of 32 involving Codex.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Codex or any similar agent and adjust the details to your situation.
Read the roadmap, pick the smallest item that can be safely finished today, implement it on a branch with tests, and summarize the change.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
