+          FULL_PROMPT="You are completing a stale community PR #${PR_NUMBER} in repository ${REPO_NAME}.
+
+          This PR was started by @${PR_AUTHOR} but has become stale. Your job is to complete it.
+
+          PR Title: ${PR_TITLE}
+          PR Branch: ${PR_BRANCH}
+
+          Your tasks:
+          1. Clone the repository ${REPO_NAME} locally.
+          2. Check out the PR branch: ${PR_BRANCH}
+          3. Review the current state of the PR and understand what it's trying to accomplish.
+          4. Read the PR description and any comments/review feedback on the PR.
+          5. Complete any unfinished work on the PR:
+             - Fix any issues mentioned in review comments
+             - Ensure the code follows the repository's coding standards
+             - Add any missing tests if applicable
+             - Fix any linting or type errors
+          6. Run the appropriate checks (lint, type-check, tests) to ensure the PR is ready for review.
+          7. Commit your changes with clear commit messages.
+          8. Push your changes to the PR branch.
+          9. Post a summary comment on the PR explaining what you completed.
+
+          Rules and Guidelines:
+          1. Respect the original author's intent and approach - don't rewrite the PR from scratch.
+          2. Make minimal, focused changes that complete the PR's original goal.
+          3. Follow the existing code style and conventions in the repository.
+          4. If the PR's original approach seems fundamentally flawed, explain why in a comment instead of making major changes.
+          5. Never ask for user confirmation. Never wait for user messages.
+          6. Credit the original author in your commit messages where appropriate."
