Animation Spec Skill

SkillDocs & knowledge

Generate animation specifications, easing curves, and motion design documentation

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the Animation Spec Skill skill
