Plaster From Patch

Create a 🩹 Plaster config for a patch the user has already written. The user made a normal Brave-core change the usual way — edited an upstream source under src/, then ran pnpm run update_patches to generate patches/<dashed-path>.patch — and now wants the equivalent rewrite/<path>.yaml so the change is expressed as a robust regex substitution instead of a brittle context patch.

Scope — read this first

The only thing this skill produces is the plaster config (rewrite/<path>.yaml).

• It does not modify the Chromium source, the patch, or any other file.
• It does not create chromium_src shadow files or move code around.
• It does not decide whether the change should be a plaster — the user already decided that by writing the patch. Author a config that reproduces the patch, following the guidelines.
