Animate

What it does

When your agent uses it

• Someone wants characters that walk
• Asks about rigs
• Says the animation looks stiff
• A hit to feel better

Example prompts

• “/animate”

Requirements

• Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 16b4156. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Animate loads about 2.4k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 247 tokens; SKILL.md has 1,055 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~247

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Give a game's characters rigs and clips that move well on a phone — the skeleton standard (one humanoid vocabulary, a mini and a quadruped family), free CC0 animated characters from Homie's starter library made phone-sized (one draw call, helper bones gone) with their clips in one shared clip library per skeleton, the library's CC0 humanoid clips retargeted at build time onto any other rig (a generated character, the person's own), the shared runtime @homie-rocks/studio/animate (idle, walk and run blended by speed, actions on the upper body while running, additive hits, hit-stop, jump, fall and land with squash and stretch, lean, look-at, springs, foot planting, crowd mode), the animation card with looping previews, and tuning a move's feel in the Game Lab. Use when someone wants characters that walk, run, jump, attack or die, asks about rigs, skeletons, bones or retargeting, says the animation looks stiff, floaty or slides, or wants a jump or a hit to feel better.
