{"agent":"claude","input":"Build this feature: let a user export their own posts as a CSV download from their profile page. Read the app first and follow its patterns for routes, blueprints, templates, translations and tests. If the app already has an export of any kind, keep it working and explain in the pull request how the new download relates to it. Only the signed-in user's own posts may be exported; a signed-out request must go to the login page. Add tests in the project's existing test style covering the download's content, ordering, that another user's posts are never included, and the signed-out case. Run the full test suite and open a pull request that explains the change in three bullets.","resources":[{"url":"https://github.com/your-org/customer-app"}]}
