Markdown instructions

Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

Installation

Install the Image Crop Rotate AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/instavm/coderunner/tree/main/skills/public/image-crop-rotate
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/instavm/coderunner.git /tmp/coderunner
mkdir -p .claude/skills
cp -r /tmp/coderunner/skills/public/image-crop-rotate .claude/skills/image-crop-rotate

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Image Crop Rotate in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Image Crop Rotate on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Image Crop Rotate is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Image Crop and Rotate

Overview

This skill provides functionality to crop images to 50% of their original size from the center and rotate them 90 degrees clockwise. It uses a reliable Python script with PIL/Pillow for consistent, high-quality image processing.

When to Use This Skill

Use this skill when the user requests:

Cropping an image to 50% from the center
Rotating an image 90 degrees (clockwise)
Both cropping and rotating an image
Image processing tasks that combine center cropping with rotation

How to Use This Skill

Overview

The skill provides a single script that performs both operations: cropping to 50% from center and rotating 90 degrees clockwise.

Process

Identify the input image: Locate the user's uploaded image file in /mnt/user-data/uploads/

Execute the script: Run the crop_and_rotate.py script with input and output paths:

bash
python scripts/crop_and_rotate.py <input_path> <output_path>

Provide the result: Move the processed image to /mnt/user-data/outputs/ and share it with the user

Script Details

scripts/crop_and_rotate.py

This script performs two operations in sequence:

Crops the image to 50% of its original size, centered
Rotates the cropped image 90 degrees clockwise

Usage:

bash
python scripts/crop_and_rotate.py input.jpg output.jpg

Arguments:

First argument: Path to input image
Second argument: Path to save processed image

Supported formats: Any format supported by PIL/Pillow (JPEG, PNG, GIF, BMP, TIFF, etc.)

Output: The script prints processing details including original size, cropped size, and final size

Example Workflow

bash
# Process an uploaded image
python /mnt/user-data/skills/image-crop-rotate/scripts/crop_and_rotate.py \
    /mnt/user-data/uploads/photo.jpg \
    /mnt/user-data/outputs/photo_processed.jpg

The script will:

Open the input image
Crop it to 50% from the center (e.g., 1000x800 → 500x400)
Rotate the cropped image 90° clockwise (e.g., 500x400 → 400x500)
Save the result to the output path

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Image Crop Rotate AI skill do?

Why use Image Crop Rotate on TypingMind?

Because you install it once and use it with any model. Image Crop Rotate is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Image Crop Rotate in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/instavm/coderunner/tree/main/skills/public/image-crop-rotate. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Image Crop Rotate?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Image Crop Rotate?

As many as you like. As long as a model supports skills, you can use Image Crop Rotate with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Image Crop Rotate AI skill free?

Yes. It is published on GitHub by instavm under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
