Agent skill from0x0funky/agent-sprite-forge
Turn one approved master still into a character's whole animated sprite set - one image-to-video clip per action (idle, walk, run, attack, jump, hurt, cast and so on), all from that still, generated through generate2dmedia route_media.py (the xAI API when a key is configured, else the local Grok CLI) - then gate each take, key it with a soft matte, register it to the master, pick loops or retime actions, finish (HD by default, pixel on request) and package fixed-canvas frames, alpha WebM, packed MP4 for iPhone and a PNG fallback with engine metadata and a JS runtime. Also processes a supplied clip. Use for character and creature animation, fluid motion and any video-to-sprite work. Not for FX, icon or prop sheets (generate2dsprite), maps or plate loops (generate2dmap), code-drawn animation (codeart2d, only on request) or calling a video API by itself (generate2dmedia).

1# Video to 2D Animation23An approved still sets identity and geometry, a video model supplies motion, and deterministic4tools prepare it for the engine. Video is not promised to be smaller, seamless or cheaper than sheets.56## Use when78- Animating a character or creature: every action comes from one approved master still, one clip per action.9- Fluid motion from an accepted master: idle breathing, walks, runs, attacks, casts, hair, capes, creatures.10- A supplied clip must become transparent, registered, looped frames and engine video.1112## Do not use when1314- FX, icon or prop sheets: [generate2dsprite](../generate2dsprite/SKILL.md).15- Water, fire or mist inside a still scene plate: [generate2dmap](../generate2dmap/SKILL.md). Only an API or CLI call: [generate2dmedia](../generate2dmedia/SKILL.md).16- Code-drawn animation the user asked for: [codeart2d](../codeart2d/SKILL.md).1718## Capability check (once per session)1920Run `python "<skill-dir>/../generate2dmedia/scripts/forge_doctor.py" --host-tools <tools> --save <output>/doctor.json`, where `<tools>` lists the media tools in your own tool list (`image_gen`, `image_edit`, `image_to_video`) or `none`. Its `ROUTES` block shows which API keys are configured (yes or no), the local readiness and the resolved order. If `encoding.stdout` fails, set `PYTHONUTF8=1`. `python "<skill-dir>/scripts/video2dsprite.py" doctor` checks ffmpeg (5.1+, VP9 alpha round trip).2122## Art source23…
