Anima Security Basics

Overview

This workflow protects the Anima and Figma credentials used by a design-to-code pipeline while keeping generated output reviewable. It applies least privilege to the design source, keeps tokens on the server, and makes secret exposure or unexpected file access a fail-closed condition.

Prerequisites

• A managed secret store and separate development, staging, and production bindings for ANIMA_TOKEN and FIGMA_TOKEN.
• An allowlist of Figma file keys and component node IDs, with an owner for each design source and a documented rotation/revocation contact.
• A non-production fixture and a disposable staging workspace for testing token scope, generated artifacts, and rollback behavior.
• Repository secret scanning and a deterministic generated-code directory; never use real customer or personal design data as the test fixture.

Security Checklist

• Anima token stored in secret manager (not .env in prod)
• Figma PAT has minimum required scope (file:read only)
• SDK runs server-side only (never ship tokens to browser)
• .env files gitignored and chmod 600
• CI secrets stored in GitHub Secrets, not workflow files
• Generated code reviewed before committing (no embedded tokens)

Instructions

Step 1: Figma Token Scope Restriction

# When creating a Figma Personal Access Token:
# - Give it the MINIMUM scope needed: File Content (read-only)
# - Do NOT grant write access unless you need Figma plugin features
# - Set an expiration date (90 days recommended)
# - Create separate tokens for dev vs CI environments

Step 2: Server-Side Only Enforcement

// src/anima/safety.ts
// Anima SDK is designed for server-side use only

function validateEnvironment(): void {
  if (typeof window !== 'undefined') {
    throw new Error('Anima SDK must run server-side only — never import in browser code');
  }
  if (!process.env.ANIMA_TOKEN) throw new Error('ANIMA_TOKEN not set');
  if (!process.env.FIGMA_TOKEN) throw new Error('FIGMA_TOKEN not set');
}

// Call this at startup
validateEnvironment();

Error Handling

All failures should preserve the previous known-good generated revision. Do not print token values, design content, personal identifiers, or full request payloads while diagnosing a failure.

Step 3: Secret Manager Integration

// src/anima/secrets.ts
async function loadAnimaSecrets(): Promise<{ animaToken: string; figmaToken: string }> {
  const { SecretManagerServiceClient } = await import('@google-cloud/secret-manager');
  const client = new SecretManagerServiceClient();

  const [animaVersion] = await client.accessSecretVersion({
    name: `projects/${process.env.GCP_PROJECT}/secrets/anima-token/versions/latest`,
  });
  const [figmaVersion] = await client.accessSecretVersion({
    name: `projects/${process.env.GCP_PROJECT}/secrets/figma-token/versions/latest`,
  });

  return {
    animaToken: animaVersion.payload?.data?.toString() || '',
    figmaToken: figmaVersion.payload?.data?.toString() || '',
  };
}

Output

• Figma token with minimal scope (read-only)
• Server-side enforcement preventing browser usage
• Secrets loaded from cloud secret manager

Examples

Run a staging preflight with an allowlisted synthetic file and verify that the process can read the managed bindings without revealing their values:

export FIGMA_FILE_KEY="synthetic-staging-file"
node scripts/anima-preflight.mjs \
  --file-key "$FIGMA_FILE_KEY" \
  --node-id "1:2" \
  --check-token-scope \
  --assert-server-only \
  --redact-output

The preflight should fail closed if either secret is absent, the file or node is not allowlisted, or a generated artifact contains a token. Record only the environment, source identifier, scope result, artifact digest, and cleanup result in the receipt; never record the credentials or design contents.
