  • src/index.js:176-187 (handler)
    The CallToolRequest handler for generate-framelayout. It destructures layoutType, views, and configuration from args, creates a FrameLayoutGenerator instance, calls generateLayout(), and returns the generated code as text content
    case "generate-framelayout": {
    const { layoutType, views, configuration = {} } = args;
    const generator = new FrameLayoutGenerator();
    const code = generator.generateLayout(layoutType, views, configuration);

Tool Definition Quality

C2.4/5.0
Behavior2/5

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

No annotations are provided, so the description must disclose behavior. It only says 'generate code', which is non-destructive, but doesn't clarify idempotency, side effects, or whether it modifies anything.

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

Conciseness3/5

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

A single sentence is concise but too brief for a 3-parameter tool with nested objects. It lacks necessary detail without being wasteful.

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

Completeness1/5

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

Given the complexity (3 parameters, nested objects, no output schema, no annotations), the description is severely incomplete. It fails to explain enum values, view structure, configuration options, or output format.

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

Parameters1/5

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

With 0% schema description coverage, the description must explain parameters. It does not mention layoutType, views, or configuration, leaving the agent to infer from the schema alone.

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

Purpose4/5

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

Description clearly states the tool generates FrameLayoutKit code for iOS layouts, distinguishing it from siblings like convert-autolayout or validate-framelayout. However, it lacks specificity about output format (e.g., Swift, XML).

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

Usage Guidelines2/5

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

No guidance on when to use this tool versus alternatives like convert-autolayout or generate-viewcontroller. The description does not mention prerequisites or exclusions.

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