+## Image Generation
+
+- Gunakan `generate_image` untuk membuat gambar dari teks prompt.
+- Simpan ke path yang diminta user (misal ~/Downloads).
+- Model default ada di config, cukup specify prompt dan output_path.
+- Support aspect ratio (1:1, 16:9, dll) dan resolution (512, 1K, 2K, 4K).
+- Support image-to-image: gunakan parameter `input_images` dengan list path/URL gambar referensi.
+- Untuk workflow berkelanjutan (modifikasi gambar sebelumnya), gunakan path file dari response sebelumnya sebagai `input_images`.
+
 ## Git Policy
 
 - Kamu boleh menjalankan `git status`, `git diff`, `git log` secara bebas untuk inspeksi.
