description	Walk the developer through the implemented code changes (diff) step-by-step in the chat interface, explaining each part and pausing for questions.

Code Walkthrough

Use this skill when the developer wants to review and understand a set of code changes (either a draft diff in the workspace or a recently committed change) step-by-step.

The goal is to explain the "why" and "how" of the changes progressively, giving the developer space to ask questions or suggest modifications for each part before moving on.

Steps

1. Identify the Changes

Locate the diff to walk through:

• For uncommitted changes: use git diff HEAD (or similar).
• For a recent commit: use git show <commit-hash> or git diff HEAD~1 HEAD.
• If the changes are already discussed in the context, use the context.
• If you are unsure, ask the user for confirmation.

2. Group into Logical Steps

Group the changes into logical steps to avoid overwhelming the developer.

• Group by file or by logical feature if changes are spread across files. Think about presenting the steps in chronological order to represent how the feature/fix was built out.
• Keep track of the current step index (e.g., "Step 1 of 3").

3. Progressive Walkthrough

For each logical group of changes:

1. Present the Change:
   • State the file path and what part of the code is changing.
   • Show the relevant diff snippet or code block.
2. Explain the Logic:
   • Explain why this change was made (the bug it fixes or the feature it implements).
   • Explain how it works (the mechanism of the change).
   • Keep the explanation concise and direct (adhere to "No Bullshit" guidelines).
3. Pause for Questions:
   • Ask the developer if they have any questions or if they are ready to move to the next step.
   • End your turn and wait for the developer's response.

4. Handle Feedback

• If the developer has questions:
  • Answer them directly and clearly.
  • Wait for their confirmation before moving on.
• If the developer suggests changes:
  • Discuss the changes and implement them if agreed.
  • Re-explain the updated change and ask for approval again.
• If the developer says they are ready:
  • Proceed to the next step.

5. Wrap Up

Once all steps are completed:

• Briefly summarize the overall change.
• Ask if there are any final questions or next steps.
