imagemagick

Transform still images with ImageMagick v7 (magick command). Pairs well with vision.describe — describe an image to decide what to do, then operate on it here. Always write to a new output file.

ImageMagick v7 uses magick in.png out.jpg. Legacy v6 uses convert; if only convert exists, substitute it for magick in the examples below.

Setup health check (run first, every session)

Verify with one solo step:

[{ "tool": "os.shell.run", "args": { "cmd": "magick", "args": ["--version"] } }]
