Show Me The Code

Rule: when this skill is requested, present code changes as unified diffs (diff -u format), including one-liners, new files, and deleted files.

• 3 lines of unchanged context above and below each hunk where available; file boundaries may leave fewer
• New file: --- /dev/null / deleted file: +++ /dev/null
• No filename? Use a/snippet.ts
• Multiple files: one diff block per file

After the diff: optional 1–3 sentence why.

Example

Asked to "make total ignore negative prices and show the diff", the response starts with the diff in diff -u format — context where available, file headers, hunk header — followed by one line of why:

--- a/src/cart.ts
+++ b/src/cart.ts
@@ -1,5 +1,5 @@
 export function total(items: Item[]): number {
   return items.reduce((sum, item) => {
-    return sum + item.price;
+    return sum + Math.max(0, item.price);
   }, 0);
 }

Clamping each price at 0 prevents a refunded line item from reducing the cart total below the legitimate sum.
