The optional `maxDimension` parameter (positive integer, max 65536, default 1024) caps the longer edge of the rendered PNG in pixels — increase it when you need to inspect fine detail, decrease it for thumbnails or to save context. The JSON metadata entry in the response includes both `width`/`height` (the rendered PNG size) and `original_width`/`original_height` (the node's natural canvas size before any clamping), so callers can decide whether to re-request at a higher `maxDimension`. Use the nodeId parameter to specify a node id. nodeId parameter is REQUIRED. Use the fileKey parameter to specify the file key. fileKey parameter is REQUIRED. If a URL is provided, extract the file key and node id from the URL. For example, if given the URL https://figma.com/design/pqrs/ExampleFile?node-id=1-2 the extracted fileKey would be `pqrs` and the extracted nodeId would be `1:2`. If the URL does not include `node-id`, ask the user for a node-specific URL. Do not pass an empty or guessed nodeId. This tool is not supported for Figma Make Files (URLs containing `/make/`). By default this tool returns a short-lived URL to the screenshot plus curl instructions for downloading the PNG — the URL+curl path is strongly preferred because it uses far fewer tokens than embedding the image inline. The `enableBase64Response` parameter defaults to `false`. Only set `enableBase64Response: true` when the agent cannot fetch URLs (no shell access, no HTTP client, or a sandboxed environment that blocks outbound requests); when set, an inline base64 image entry is appended to the response in addition to the URL and curl instructions. If the URL is of the format https://figma.com/design/:fileKey/branch/:branchKey/:fileName then use the branchKey as the fileKey.

Spawned agents inherit your current model by default. Omit `model` to use that preferred default; set `model` only when an explicit override is needed.\nThis spawn_agent tool provides you access to sub-agents that inherit your current model by default. Do not set the `model` field unless the user explicitly asks for a different model or there is a clear task-specific reason. You should follow the rules and guidelines below to use this tool.\n\nDo not spawn sub-agents unless the user or applicable AGENTS.md/skill instructions explicitly ask for sub-agents, delegation, or parallel agent work.\nRequests for depth, thoroughness, research, investigation, or detailed codebase analysis do not count as permission to spawn.\nAgent-role guidance below only helps choose which agent to use after spawning is already authorized; it never authorizes spawning by itself.\n\n### When to delegate vs. do the subtask yourself\n- First, quickly analyze the overall user task and form a succinct high-level plan. Identify which tasks are immediate blockers on the critical path, and which tasks are sidecar tasks that are needed but can run in parallel without blocking the next local step. As part of that plan, explicitly decide what immediate task you should do locally right now. Do this planning step before delegating to agents so you do not hand off the immediate blocking task to a submodel and then waste time waiting on it.\n- Use a subagent when a subtask is easy enough for it to handle and can run in parallel with your local work. Prefer delegating concrete, bounded sidecar tasks that materially advance the main task without blocking your immediate next local step.\n- Do not delegate urgent blocking work when your immediate next step depends on that result. If the very next action is blocked on that task, the main rollout should usually do it locally to keep the critical path moving.\n- Keep work local when the subtask is too difficult to delegate well and when it is tightly coupled, urgent, or likely to block your immediate next step.\n\n### Designing delegated subtasks\n- Subtasks must be concrete, well-defined, and self-contained.\n- Delegated subtasks must materially advance the main task.\n- Do not duplicate work between the main rollout and delegated subtasks.\n- Avoid issuing multiple delegate calls on the same unresolved thread unless the new delegated task is genuinely different and necessary.\n- Narrow the delegated ask to the concrete output you need next.\n- For coding tasks, prefer delegating concrete code-change worker subtasks over read-only explorer analysis when the subagent can make a bounded patch in a clear write scope.\n- When delegating coding work, instruct the submodel to edit files directly in its forked workspace and list the file paths it changed in the final answer.\n- For code-edit subtasks, decompose work so each delegated task has a disjoint write set.\n\n### After you delegate\n- Call wait_agent very sparingly. Only call wait_agent when you need the result immediately for the next critical-path step and you are blocked until it returns.\n- Do not redo delegated subagent tasks yourself; focus on integrating results or tackling non-overlapping work.\n- While the subagent is running in the background, do meaningful non-overlapping work immediately.\n- Do not repeatedly wait by reflex.\n- When a delegated coding task returns, quickly review the uploaded changes, then integrate or refine them.\n\n### Parallel delegation patterns\n- Run multiple independent information-seeking subtasks in parallel when you have distinct questions that can be answered independently.\n- Split implementation into disjoint codebase slices and spawn multiple agents for them in parallel when the write scopes do not overlap.\n- Delegate verification only when it can run in parallel with ongoing implementation and is likely to catch a concrete risk before final integration.\n- The key is to find opportunities to spawn multiple independent subtasks in parallel within the same round, while ensuring each subtask is well-defined, self-contained, and materially advances the main task.\n\nexec tool declaration:\n```ts\ndeclare const tools: { multi_agent_v1__spawn_agent(args: {\n  // True forks the current thread history into the new agent; false or omitted starts with only the initial prompt.\n  fork_context?: boolean;\n  // Structured input items.

PROCEDURE createFulfillment(order, lines, trackingData):
    1. GUARD: Verify order.financial_status IN ('paid', 'partially_refunded')
       IF NOT: throw FulfillmentGuardException

    2. FOR EACH line in request:

       unfulfilled = order_line.quantity - fulfilledSoFar
       VALIDATE requested quantity <= unfulfilled

#### Fulfillment Status Transitions (Admin Button Actions)

Fulfillment status transitions are triggered by explicit admin button clicks. There are no automatic transitions for physical products.

```mermaid
stateDiagram-v2
    [*] --> pending : Fulfillment created (admin clicks "Create fulfillment")
    pending --> shipped : Admin clicks "Mark as shipped"
    shipped --> delivered : Admin clicks "Mark as delivered"

    note right of pending : Fulfillment record created with tracking data
    note right of shipped : Sets shipped_at timestamp, sends tracking email to customer
    note right of delivered : Sets delivered_at timestamp
```

**Admin buttons on each fulfillment card:**

| Button | Shown When | Action |
|---|---|---|
| "Mark as shipped" | `fulfillment.status = pending` | Transitions to `shipped`, sets `shipped_at`, dispatches `FulfillmentShipped` event, sends tracking email |
| "Mark as delivered" | `fulfillment.status = shipped` | Transitions to `delivered`, dispatches `FulfillmentDelivered` event |

When transitioning to `shipped`:
