Author a Spine animation with rigc from key poses — an idle, a loop, a move from one picture to another — with timing and spacing, ease in and out, anticipation, arcs, overlap, follow-through, squash and stretch, and candidate variants a person can choose between. Use when the request is a movement on an existing or planned rig, in the animator's words too: "animate this rig", "make it breathe", "go from pose A to pose B", "make it feel heavier", "the cape should follow through". Not for…

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

# Motion — what goes between two poses

Load this when the request is a **movement rather than a skeleton**: a sentence of
intent, between zero and N pictures of what the movement passes through, and a
Spine animation somebody would choose coming back. Every rule below is owned by
[MOTION.md](https://github.com/rig-c/core/blob/main/docs/MOTION.md); this file says when to open it and what it will
not do for you.

📖 **A failure line ends with the command that prints its row of the guide** —
` (see rigc guide <RULE>)`. Run that command first, before reading anything else:
it prints that rule's row of the shipped guide and nothing else. `rigc guide §<n>`
(and `§<n>.<m>`, `§<n>.<m>.<k>`) prints the section's heading, own prose and
subsection index from `docs/AUTHORING.md`; add `--all` to include subsection
bodies. A leaf prints its full text either way. Sizes describe full ledger spans;
`--all` with a rule name is refused, exit 2. A compile error points at its stable
`CE_` code row. `rigc guide §5.1.<k>` prints a numbered compile-error group of
at most 30,000 UTF-8 bytes, and `rigc guide §5.1` prints the introduction and
…

How to install

The exact contents, by fingerprint
mdr add firejune/rigc/rigc-motion@sha256:c8864ff2c8d94d1d

The line at the top of this page pins the label git:20261014.844d2a1, 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.
