Anima Webhooks Events

What it does

When your agent uses it

• Automatic Anima code generation on design changes
• Building event-driven design-to-code pipelines
• Auto-generating components when Figma files change
• Integrating design updates into CI

Example prompts

• “anima webhook”
• “figma webhook”
• “anima auto-generate on change”
• “/anima-webhooks-events”

Requirements

• Node.js
• A credential in FIGMA_TOKEN
• A credential in FIGMA_WEBHOOK_SECRET
• Compatibility (from SKILL.md): Requires Node.js 20+, approved Anima API access, current Anima SDK documentation, and authorized Figma or website source access
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(curl:*)

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1Register Figma Webhook
2. 2Webhook Handler
3. 3Figma Webhook Event Types

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash(curl:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.figma.com

  Also links to:

  • figma.com
  • docs.animaapp.com

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

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • FIGMA_TOKEN
  • FIGMA_WEBHOOK_SECRET

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

• Compatibility

  Requires Node.js 20+, approved Anima API access, current Anima SDK documentation, and authorized Figma or website source access

  From compatibility in the SKILL.md frontmatter.

Context cost

Anima Webhooks Events loads about 1.7k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 498 words of instructions outside code blocks.

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

~83

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

~1.7k

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

~1.9k

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

Use Figma webhooks to trigger automatic Anima code generation on design changes. Use when building event-driven design-to-code pipelines, auto-generating components when Figma files change, or integrating design updates into CI. Trigger with: "anima webhook", "figma webhook", "anima auto-generate on change".
