⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 29, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
The script works and the rotation direction is genuinely correct: on a marked 100x60 test image the crop came out 50x30, the final image 30x50, and a corner-pixel check confirmed a true clockwise turn (the marker moved top-left to top-right). The problem is that it does exactly what Claude does unprompted - the eight-line no-skill version produced a byte-identical output file on both PNG and JPEG input, 11401 bytes either way, so there is nothing to gain from installing it. Both paths also share a Pillow trap the skill never warns about: saving a JPEG with no quality argument dropped the result to 19.3 dB PSNR against a lossless reference where passing quality=95 gives 35.8 dB, an 11 KB file where 49 KB was warranted. Setup friction is the documentation pointing at /mnt/user-data/uploads and /mnt/user-data/outputs, which do not exist outside Claude.ai's sandbox, so you have to translate every path by hand.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 5/10
- Docs & honesty 3/5
What Image Crop and Rotate does
A single Python/Pillow script that crops an image to 50 percent of its width and height from the center, then rotates the result 90 degrees clockwise. It triggers on requests to center-crop, to rotate an image 90 degrees, or to do both at once. Both operations are fixed: there is no argument for crop ratio, rotation angle or direction.
How to install Image Crop and Rotate
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Image Crop and Rotate
-
/image-crop-rotateOne Pillow script: center-crop an image to half size, rotate it 90 clockwise
It also activates on plain-language prompts like these:
-
Center-crop this photo to half size and rotate it 90 degrees clockwise -
Rotate screenshot.png 90 degrees clockwise for me please -
Crop this image to 50% from the center then turn it a clockwise quarter
Frequently asked questions
- Is the Image Crop and Rotate skill free?
- Yes. The skill itself is free from instavm/coderunner. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Image Crop and Rotate work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 29, 2026. Verdict: Works with setup. The script works and the rotation direction is genuinely correct: on a marked 100x60 test image the crop came out 50x30, the final image 30x50, and a corner-pixel check confirmed a true clockwise turn (the marker moved top-left to top-right).

- 7.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 3/5.
- How do I install Image Crop and Rotate?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Image Crop and Rotate with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
