 ## Agent-Specific Notes
 - Vocabulary: "makeup" = "mac app".
+- When working on a GitHub Issue or PR, print the full URL at the end of the task.
 - When answering questions, respond with high-confidence answers only: verify in code; do not guess.
 - Never update the Carbon dependency.
 - Any dependency with `pnpm.patchedDependencies` must use an exact version (no `^`/`~`).
