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 64 by interest), and one of 81 involving Amazon Bedrock.

How you could try it

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

I want a coding agent to plan first, work on a branch, and show me the diff before anything is merged. The tool in the source case was Amazon Bedrock.

Saved

Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
