Give a coding agent a first task it can finish

Start with a small change, a clear check and a way to undo it.

What you’ll finish with One reviewable code change with evidence that it works.

AI-generated guidance. These are suggested workflows, not hands-on test results.

The walkthrough

Choose a bounded change
Start with a reproducible bug, a small form validation change or a missing test. Write down the current behavior and the behavior you want. Avoid combining a redesign, dependency upgrade and database migration in the same first task.
Give the agent a map
Point it to the relevant files, project instructions and test command. Ask it to inspect the existing approach before editing. Keep credentials out of prompts and give only the permissions needed for the task.
Ask for a small patch
Work on a branch or a recoverable copy. Request the smallest change that fixes the issue. Let the agent explain assumptions before it introduces new dependencies or changes a public interface.
Verify the result yourself
Read the diff and run a check that would fail with the original bug. Try the changed behavior in the application. A confident explanation and a passing test that merely repeats the implementation are not enough.

Text to start with

Replace the bracketed sections with your own details.

Investigate [bug] in [files]. Expected behavior: [result]. First explain the cause. Make the smallest appropriate change using the project conventions. Run [test command] and add a regression check if needed. Summarize what changed, the checks you actually ran and anything still unverified.

Check the result

Does the test reproduce the original failure?
Are unrelated files or dependencies changed?
Can you explain and undo the patch?

Before paying

Compare total cost for a finished task, including retries. Check agent usage, premium requests and hosting charges where applicable; a monthly subscription may not cover every action.
