This skill should be used when the user asks to "edit an image", "modify a photo", "inpaint", "outpaint", "extend an image", "replace object in image", "add element to image", "resize image for social media", "crop image", "adapt image for Twitter", "convert image to OG format", or needs AI-powered image editing with masks.

scripts/edit.tsExecutes pre-written implementation plans: critically reviews, follows bite-sized steps exactly, runs verifications, tracks progress with checkpoints, uses git worktrees, stops on blockers.
Dispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.
Guides idea refinement into designs: explores context, asks questions one-by-one, proposes approaches, presents sections for approval, writes/review specs before coding.
Edit images using Nano Banana Pro (gemini-3-pro-image-preview).
Use this skill when the user asks to:
Uses Gemini's multimodal capabilities to understand and edit images via natural language. The model takes the source image and a text prompt describing the desired edit, then generates a new image with the changes applied.
Semantic masking: Instead of requiring precise pixel masks, describe what to change in your prompt. The model understands context and can target specific regions.
Optional mask images: You can still provide a mask image (white = edit area) as a visual hint, but it's not required. Descriptive prompts often work better.

Do not read generated images back into context. The script outputs only the file path. Ask the user to visually inspect the result. To inspect programmatically, optimize the image first (via the optimize-images skill) to avoid filling the context window with large uncompressed image data.
