# designComponent

Design ONE reusable, on-brand SLIDE COMPONENT and add it to the org's component library so every future branded deck (autoDesignWhiteboard designProfile:'branded-executive') can use it. This is the self-improving design loop: an agent AUTHORS the component as a declarative template (a gradient/shadow/curve SVG skin + a native editable PPTX shape + reflowing bound-text slots), RENDERS it, a vision critic COMPARES the render to your brief and lists gaps, and it FIXES + re-renders until polished — then validates and stores it. Use it to grow the deck component catalogue beyond the built-ins (e.g. a 'kpi.delta' stat with an up/down arrow, a 'quote.card', a 'logo.strip'). Browse-first: if a component with this key already exists it is reused (pass force:true to redesign). Provide example sampleSlots so it can lay out real content, and a projectId for the small preview board it builds. Returns the stored component, the per-round critique trail, and the preview board id. It uses a few AI calls + renders (no flat credit charge); the new component is then free to reuse forever.

- Parameters: 11 (5 required)
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `key` | string | yes | The component key, lowercase dotted, e.g. 'kpi.delta'. This is how decks reference it; reused if it already exists. |
| `tags` | array | no | Optional search tags. |
| `force` | boolean | no | Redesign even if a component with this key already exists (default false = reuse). |
| `title` | string | yes | A short human title, e.g. 'KPI with delta arrow'. |
| `boxCols` | number | no | Optional width in grid columns (2-12, default 4). |
| `boxRows` | number | no | Optional height in grid rows (2-12, default 5). |
| `category` | string | no | Optional catalogue category (e.g. 'data', 'narrative', 'comparison'). |
| `projectId` | string | yes | Project to create the small preview board in (where the render iterations are shown). |
| `description` | string | yes | What the component IS, WHEN to use it, and what it should LOOK like (the richer the better — this drives both the designer and the critic). |
| `sampleSlots` | object | yes | Example slot content to render with, e.g. { value: '47%', label: 'Revenue growth', delta: '+12 pts' }. The slot keys become the component's editable fields. |
| `referenceImageUrl` | string | no | Optional URL of a reference image the component should match; the critic compares the render to it. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "designComponent",
    "arguments": {
      "key": "<key>",
      "title": "<title>",
      "projectId": "<projectId>",
      "description": "<description>",
      "sampleSlots": {}
    }
  }
}
```

## Why designComponent is rated Medium

This tool creates and modifies organizational design assets that persist in a shared library, making it a Write operation rather than Read. The severity is medium because while the component library is an important shared resource, individual components can be updated, removed, or deprecated without irreversible damage to the organization.

From the tool's own definition: "The tool CREATES and ADDS a reusable slide component to the organization's component library ('add it to the org's component library')."

Risk signals: High parameter count (11 properties) · Bulk/mass operation — affects multiple targets

## Use case

AI agents use designComponent to create or update resources in Stable Baseline, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stable Baseline environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Stable Baseline:

```json

  "default": "deny",
  "tools": {
    "designComponent": {
