## What it does

FilmKit runs in the browser with nothing to install. It talks to a Fujifilm X-series camera over WebUSB using PTP, the protocol behind Fujifilm X RAW STUDIO, and lets the camera's own processor turn RAW into JPEG. This skill hands the agent the details of that stack: preset property codes, PTP packet layout, profile handling.

It covers reading and writing custom film simulation presets on the camera itself, in slots `0xD18E`–`0xD1A5` through `GetDevicePropValue` and `SetDevicePropValue`. Presets can live in a local library and move between camera and storage by drag and drop. RAF files go to the camera and full-quality JPEGs come back. Drop a RAF in and the skill works out which preset shot it. Presets travel as files, links or pasted text.

You need a Chromium browser — Chrome, Edge or Brave — on desktop or Android, since WebUSB lives there. The camera connects over USB. On Linux with Chrome in Flatpak, add a udev rule for `idVendor` `04cb` in `/etc/udev/rules.d/99-fujifilm.rules`, then reload with `sudo udevadm control --reload-rules && sudo udevadm trigger`. Skip that and the browser never sees the camera.

## When to use it
- read and rewrite film simulation presets on the camera
- keep a local preset library and drag presets between camera and storage
- send a RAF file to the camera and pull back a full-quality JPEG
- identify which preset shot a given RAF file
- move presets as a file, a link or pasted text

## Example prompts
- Connect to my Fujifilm camera over WebUSB and list the current presets
- Copy a preset from the local library into a camera slot
- Send `shot.RAF` to the camera and fetch the converted JPEG
