What it does

This skill teaches an AI agent to use a command-line tool called cli-anything-gimp for editing images without a graphical interface. The agent can create project files, add and arrange layers, resize or crop canvases, add text and rectangles, and render the result to a PNG or other image. The tool is built on the Pillow Python imaging library, and it keeps undo and redo history so changes can be reverted.

Great for

  • Developers who want an AI agent to batch-process or compose images in scripts
  • Designers who want quick layered compositions such as posters without opening GIMP
  • Anyone automating repeatable image edits that must be reviewed afterwards

Skip it if

  • Users who need full GIMP features such as brushes, painting or advanced selections, since the skill only covers the listed commands (the reason: the commands are a limited subset)
  • Workflows where text or rectangles must be verified from the project file alone, since draw operations are only applied at render time (review the exported image instead)

Try asking

  • “Create a new image project, add a text layer saying 'Launch Night', and render it to output.png”
  • “Resize a canvas to 1080x1080 and set its DPI to 300”
  • “Add a photo as a layer, offset it by -48 pixels, apply a filter and export the result”
  • “Show a histogram of an image and list the media files referenced in a project”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Use the --json flag and absolute file paths so the agent can parse output reliably
  • Always open the exported image to check text and rectangle placement, because draw operations are applied only at render time
  • Install the package with pip and confirm the CLI runs with --help before asking the agent to edit images
