Implementation Reference

  • server.js:906-927 (registration)
    The tool 'swing_fill_light_right' is registered with mcpServer.registerTool(). It has no input schema (empty object) and its handler sends a 'swingFillLightRight' command type via routeToCurrentSession(), returning a confirmation text response.
    mcpServer.registerTool(
      'swing_fill_light_right',
      {
        title: 'Swing Fill Light Right',
        description: 'Rotate the fill light rightward in an arc around the center of the model',
        inputSchema: {}
      },
      async () => {
        routeToCurrentSession({
          type: 'swingFillLightRight'
        });
    
        return {
          content: [
            {
              type: 'text',
              text: 'Fill light swung right'
            }
          ]
        };
      }
    );
  • The handler for 'swing_fill_light_right' is an async function that routes a command of type 'swingFillLightRight' to the current session's browser client via routeToCurrentSession() and returns a text response 'Fill light swung right'.
    mcpServer.registerTool(
      'swing_fill_light_right',
      {
        title: 'Swing Fill Light Right',
        description: 'Rotate the fill light rightward in an arc around the center of the model',
        inputSchema: {}
      },
      async () => {
        routeToCurrentSession({
          type: 'swingFillLightRight'
        });
    
        return {
          content: [
            {
              type: 'text',
              text: 'Fill light swung right'
            }
          ]
        };
      }
    );
  • The tool has an empty input schema ({}) meaning it takes no parameters. The description states 'Rotate the fill light rightward in an arc around the center of the model'.
    'swing_fill_light_right',
    {
      title: 'Swing Fill Light Right',
      description: 'Rotate the fill light rightward in an arc around the center of the model',
      inputSchema: {}
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, the description carries full burden; it accurately discloses the rotation motion along an arc. No hidden side effects are mentioned, but the action is simple.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with action and target, no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Description is adequate for a parameterless tool; it explains the action and direction. Missing details like incremental behavior, but not critical.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 0 parameters with 100% coverage, so baseline is 4. Description adds no parameter info as none exist.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the action ('Rotate'), the resource ('fill light'), and direction ('rightward'), distinguishing it from siblings like swing_fill_light_left.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implicit from the name and context, but no explicit guidance on when to use this tool over alternatives (e.g., rotate_fill_light_clockwise).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
