Specialization of playwright-harness for CAMERA / segmentation testing in the browser: put a real PERSON in front of getUserMedia so MediaPipe / selfie segmentation produces an actual mask, then verify background-replacement / blur / shader effects by vision. Use when the task is "test the mask on web", "verify segmentation in the browser", "feed the camera a person fixture", "check a camera/background effect in Chrome", or any time a web app must SEE a human through the webcam without…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Camera / Mask Testing: specialization of playwright-harness **Read `playwright-harness` first.** The base owns prerequisites, the run pattern (write to `/tmp/pw-*.mjs`, run with `playwright` resolvable), and the drive/assert + WebGL-GPU patterns. This skill changes only how the camera is fed. MediaPipe selfie segmentation runs in WASM and works headless. ## Prerequisites (in addition to the base) `ffmpeg`, only to turn the still fixture into the looping `.y4m` Chrome plays as a fake camera; no system install needed, `npm i ffmpeg-static` in a /tmp dir gives a binary path. This skill ships two fixtures (derivations and provenance in `fixtures/README.md`): - **`fixtures/person-web.png`**: a 640x480 webcam-shaped frame, full-body subject occupying ~82% of frame height, vertically centered, on a clean light-gray ground (`#CDD0D4`). Derived from `android-emulator-mask-testing/fixtures/person-framed.png`. Web presents the capture file **1:1** (no sensor crop), so do NOT reuse the Android fixture directly; its left-quarter framing compensates an emulator sensor shift that does not exist on web. - **`fixtures/office-empty.png`**: a 1280x720 empty office, the **no-person …

How to install
mdr add simiancraft/simiancraft-skills/playwright-camera-mask-testing@sha256:9762301077eb1fffThe line at the top of this page pins the label git:20260614.b42db2c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
