Transparent-PNG cutouts / background removal for flat illustration, sticker, cartoon and avatar art — rembg (isnet-anime) with a deterministic fallback ladder for the cases ML drops.

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
# rembg Operations — cutouts for flat illustration & sticker art Turn opaque, flat-background illustration (avatars, stickers, cartoon/vector art, generated character portraits) into clean **transparent PNGs** — without regenerating the source. rembg's ML models are the default engine; the value this skill adds is the **deterministic fallback ladder** for the cases pure ML gets wrong on flat-colour art. ## The one thing to know **rembg is a semantic model, not a chroma keyer.** `isnet-anime` (the model tuned for outlined cartoon art) segments *the salient character* and ignores background *colour* — so it cannot be "helped" with a greenscreen, and it fails in two predictable ways on flat art: 1. **Pale / low-salience subjects get dropped** (a near-white moon, a mint UFO on a light background read as "not the subject"). 2. **Baked drop-shadows** survive as a grey ghost or an opaque offset blob. Both are fixed deterministically because flat sticker art always has **one flat background colour + a sealing outline**. That geometry makes a corner flood-fill colour-key exact, regardless of how pale the subject is. **The axis that matters is …

How to install
mdr add 0xdarkmatter/claude-mods/rembg-ops@sha256:1ca95f50ddc8f61eThe line at the top of this page pins the label git:20260712.9d1b846, 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.
