Resize Images Skill

Resize images in blog post assets folders. Default max width is 1000px, but can resize to any specified width.

Finding Images to Resize

If a specific image path or post is provided, use that
Otherwise, find the most recent post by looking at Public/_posts/ and selecting the textbundle with the latest date prefix (YYYY-MM-DD format)
Look in the assets/ folder within the textbundle

Supported Formats

Only process these image formats:

.jpeg
.jpg
.png

Target Width

Default: 1000px (for images wider than 1000px)
Custom: If the user specifies a width (e.g., "resize to 300px", "make it 500 wide"), use that exact width

When a custom width is specified, resize the image to that width regardless of its current size.

Process

1. Find Unstaged Images

Find images that are either:

New (untracked) files
Modified but not staged

Use git status --porcelain to identify unstaged files, then filter for images in the target assets folder.

If a specific image is requested, use that directly without checking git status.

2. Check Dimensions

For each image, check its width using ImageMagick:

/usr/local/bin/magick identify -format "%w" <image_path>

3. Report and Confirm

Present a summary of images to resize:

For default (1000px max) mode:

## Images to Resize (max 1000px)

| Image | Current Width | New Width |
|-------|---------------|-----------|
| image1.png | 2400px | 1000px |
| image2.jpg | 1800px | 1000px |

Resize these images?

For custom width mode:

## Images to Resize (to 300px)

| Image | Current Width | New Width |
|-------|---------------|-----------|
| icon.png | 512px | 300px |

Resize these images?

Use the AskUserQuestion tool to confirm before proceeding.

4. Resize Images

After confirmation, resize each image using ImageMagick:

/usr/local/bin/magick mogrify -resize <width> <image_path>

5. Report Results

After resizing, report what was done:

## Resized Images

- image1.png: 2400px → 1000px
- icon.png: 512px → 300px

Important

For default mode: only resize images wider than 1000px
For custom width mode: resize to the exact width specified
Only process unstaged images unless a specific image is requested
Always ask for confirmation before resizing
If no images need resizing, report that clearly
