Apply Patch

Git-style patch applicator. You feed it a diff hunk - lines with + (add) or - (remove), optionally context lines (space-prefixed). The skill applies the hunk to the file.

Call run_skill with skill: "apply-patch". Set command or arguments.action to apply (or apply-patch).

Arguments

• arguments.path (required) - File to patch. Relative to workspace or absolute.
• arguments.hunk (required) - The diff hunk text. Unified-style lines:
  • Space - context line (must match file)
  • - - line to remove
  • + - line to add

Example hunk:

  const x = 1;
- const old = true;
+ const updated = false;

When to use

Use when the user says things like:

• "Apply this patch to main.js"
• "Add this line after line 10"
• "Remove the debug log and add the new check"
• "Apply the diff I'm pasting"

The skill finds where the hunk applies (by matching context), then applies add/remove. Fails if the context does not match the file.
