      // --- CRITICAL: You MUST include EITHER 'action' OR 'endpoint' ---
      "action": "client:action_name", // Use for client tools (human_input, transform)
      "endpoint": "/api/tools/tool_name", // Use for backend tools (openai_call, http_fetch)
      // --- A step CANNOT have both or neither. ---
Every single step in the \`steps\` array **MUST** have exactly one of the following properties:
* \`"action"\`: Use this **only** for client-side tools listed in the manifest (e.g., \`"client:human_input"\`, \`"client:transform"\`).
* \`"endpoint"\`: Use this **only** for backend tools listed in the manifest (e.g., \`"/api/tools/openai_call"\`, \`"/api/tools/http_fetch"\`).
**A step will fail if it has NEITHER or BOTH.** The error you just saw (\`Step must have 'action' or 'endpoint'\`) was caused by forgetting this rule.
