Retype agent-written diffs to internalize new features

After an agent writes a feature, a skill shows the important diffs against a copy of the base branch and the author retypes them to understand the code. · Nov 8, 2026

Done with a custom-built or unnamed agent

What they did
After an agent writes a new feature, fcoury runs a skill that makes a copy of the base branch and presents each diff that matters, skipping imports and other boilerplate. He then types each change into an editor himself. He has also tried asking questions about specific aspects and diffs with gaps to fill in.
How it went
Retyping works well for critical work, but the time it takes means he uses it sparingly. The question and fill-in-the-gap variants help somewhat, and he is still looking for better methods and research.
Worth knowing
It is slow, so reserve it for critical features rather than everyday changes.

Try it yourself with Claude Code

I just had you build [feature name] on the branch [branch name]. Compare it against a copy of [base branch] and show me only the most important diffs, one chunk at a time, with a one-sentence explanation of why each matters. Don't modify any files; I'll retype each chunk myself, and when I say 'next' show me the following chunk until we've covered everything essential.
