EffectCraft is an open-source, pure-Rust motion-graphics, compositing and VFX app for macOS, Windows, Linux and the web — a clean-room, After Effects-shaped studio with compositions, layers, keyframes, 308 effects, expressions, Classic/Advanced 3D, tracking, roto, a render queue and Lottie, driven by a CLI, an MCP server, a localhost JSON control channel and JavaScript scripting. Trigger this skill whenever the user mentions EffectCraft, `.ecproj`/`.ecprojx`/ `.ectemplate`/`.ecpreset`…

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

# EffectCraft

**Audit basis.** Refreshed 2026-11-04 against tag **v0.21.0**, commit **`7870b5916ae0749d497d880989683bf2946d6c8b`** — `git rev-parse HEAD` in the pinned checkout confirms, and the installed `/Applications/EffectCraft.app` matches (its binary prints `effectcraft 0.21.0`). The previous release this skill described was v0.20.0 (`720c671`).

**v0.20.0 → v0.21.0 delta.** 46 files changed; the command-id set is unchanged (608 ids). Wave: a colr atom in ProRes MOV exports, shortcut scopes (panel and context, one chord per scope), a bounded encryption pre-scan after each PDF trailer, and Japanese catalog rows.

**Verify against your installed version** — the ArtCraft Launcher auto-updates, so a newer build may differ; every count quoted here was re-measured at this tag, and code paths that moved were re-cited. The measurement method for each count is in `evidence.md`.

How to install

The exact contents, by fingerprint

mdr add midasmatterhorn/artcraft-skills/effectcraft@sha256:7a61905c42a7dbb8

The line at the top of this page pins the label git:20261104.a5ac27d, 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.
