Coding
Make a small code change with an assistant
Keep the diff small, run the project, and never paste secrets into a prompt.
Describe the failing behavior
Include the file names you already suspect, the error text, and what “done” looks like (a test, a screenshot, a command). Avoid dumping the entire repository on the first try.
Work in a branch or copy
Ask for a patch to a specific function. Apply it yourself or use an editor that shows a reviewable diff. Do not accept a silent rewrite of unrelated files.
Run something real
Compile, test, or click the path you changed. If you cannot run it, you do not have evidence that the change works.
Keep secrets out
Do not paste API keys, production data, or private customer records into a prompt. Use dummy values and your own environment files.
Editor assistants such as official coding products can read a repo when you allow it. That is still your review: you own the commit.
