/comfy-gallery — Browse Generated Outputs

The user wants to browse images that ComfyUI has generated, inspect their metadata, and optionally re-run or modify workflows.

Instructions

1. **Determine the output directory.** Call `get_system_stats` to check for a custom `--output-directory` argument. If not set, use the default ComfyUI output directory (typically `~/Documents/ComfyUI/output/` or the `output/` folder relative to the ComfyUI installation).

2. **List image files.** Use the Glob tool to find image files in the output directory:

• Pattern: `**/*.png` (ComfyUI saves as PNG by default)
• Also check for `**/*.jpg`, `**/*.webp` if needed
• Sort by modification time, newest first

3. **Apply filters.** The argument is: $ARGUMENTS

Parse the filter:

• **`last N`** or **`N`**: show only the N most recent images
• **`today`**: images created today (compare file dates)
• **`yesterday`**: images from yesterday
• **Filename pattern**: glob match against filenames (e.g., `ComfyUI_00123*`)
• **No filter**: default to showing the last 10 images

4. **Present image details.** For each image, show:

• Filename
• File size (human-readable: KB/MB)
• Creation/modification date and time
• Use the Read tool to display the image thumbnail if the file is a supported image format

5. **Extract workflow metadata.** When the user selects an image or asks for details:

• Use `get_workflow (action:"from_image")` to extract the embedded workflow JSON from the PNG metadata
• Show key parameters: checkpoint used, prompt, negative prompt, seed, steps, CFG, sampler, dimensions
• Offer to visualize the workflow with `visualize_workflow`

6. **Offer actions.** For any selected image, offer to:

• **Re-run**: execute the same workflow again (new seed for variation)
• **Modify and re-run**: let the user change parameters (prompt, seed, steps, etc.) and run a modified version
• **Upscale**: create an upscale workflow using the image as input

Example

User: `/comfy-gallery last 5`

Steps:

• Find the output directory
• List all PNG files, sorted by newest
• Show the 5 most recent with filename, size, and date
• Display thumbnails
• Ask if the user wants to inspect any image's workflow

Notes

• ComfyUI embeds workflow metadata in PNG files by default — this is what `get_workflow (action:"from_image")` reads
• JPEG and WebP files may not have embedded metadata depending on ComfyUI settings
• The output directory may contain subdirectories for different workflows or dates
• If the output directory is empty, tell the user no images have been generated yet
• Large galleries (100+ images) should be filtered to avoid overwhelming output
