What it does
stamp-edge processes a screenshot or image with the Pillow script `stamp_effect.py`: it punches semicircular holes along the edge, adds a soft shadow and saves a PNG with true transparency. The result lays over any background like a sticker. The `margin` option adds a white paper border and `bg` puts the image on a light background. The `stamp_sheet.py` script tiles finished stamps into a sheet of equal-width columns and balances their heights itself. The `--cols` and `--bg` flags set the column count and background colour. The agent calls the skill for requests such as "make a stamp from this screenshot".
Who it is for. Designers and post authors who need a stamp frame for screenshots, cards and covers without manual editor work.
Good fit when
- Product screenshots are styled as stickers for a post or slide deck.
- A set of stamps with transparent backgrounds is needed to overlay on different backdrops.
- A dozen finished stamps must be tiled into one sheet for a cover.
- An image edge needs a white paper border with perforations.
Not a fit when
- A vector result is required, because the skill outputs raster PNG.
- A different edge shape is needed, such as wavy or torn.
- The image goes to a messenger as a photo, where transparency is lost after JPG compression.
Example request
Turn `shot.png` into a stamp with a white border and transparent background, then tile all `*_stamp.png` files into a three-column sheet.Limitations
Python 3 and Pillow (`pip install Pillow`) are required. The README and skill description are written in Chinese. The repository is small: two scripts and `SKILL.md`. Perforation parameters (`hole_r`, `pitch`, `outer_pad`, `shadow_alpha`) are edited at the top of the script. Messengers such as WeChat compress transparent PNG into JPG, so such stamps should be sent as files. `stamp_sheet.py` balances columns, so stamp order may change.
How to disable. Delete the `stamp-edge` folder from the agent's skills directory, for example `~/.agents/skills/`. Generated PNG files stay on disk.
FAQ
How do I install the skill?
Copy the repository folder into the agent's skills directory, for example `~/.agents/skills/stamp-edge/`. Then ask the agent to turn an image into a stamp.
What background does the output have?
By default a PNG with true transparency: holes and margins have alpha 0. The `bg` option gives a light backdrop.
Can perforation size be tuned?
Yes, through variables at the top of `stamp_effect.py`: hole radius `hole_r`, spacing `pitch`, shadow padding `outer_pad` and shadow opacity `shadow_alpha`.
Why does the stamp sheet come out in a different order?
The script places stamps into columns greedily to even out heights, and order is not preserved.
What does the margin option do?
It adds a 46-pixel white paper border around the image before the perforated edge.

README in short
The skill installs by copying the folder into the agent's skills directory. All look parameters sit at the top of the script.
