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

With zero annotations, the description carries the full burden of behavioral disclosure. It states the return type Promise<void> (async) but doesn't explain side effects: whether resources are freed, whether the engine can be re-initialized afterward, what happens to an ongoing render, or whether this is reversible. For a lifecycle-ending operation, this is a meaningful gap.

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

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

The description is compact with the signature, purpose, and version remark each on their own line. However, the version note 'ADD since EDA v4' is only marginally useful for an agent selecting a tool, and the purpose statement is minimal. It's terse but not optimally informative.

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

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

For a dispose operation with no annotations and no output schema, the description should explain lifecycle implications: what disposing does to rendering state, whether re-initialization is needed, and consequences of calling it mid-render. None of this is present. The description is adequate only at a surface level.

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

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

Schema description coverage is 100%, so the schema already documents both parameters (args and windowId). The description adds the method signature context which is mildly useful, but the args parameter ('JSON parameter array in official signature order') remains ambiguous without concrete signature details. The description doesn't compensate for the generic args schema beyond what's already present.

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

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

The Chinese phrase '停止光线追踪引擎' (stop the ray tracing engine) combined with the method signature pcb_RayTracerEngine.dispose() makes the purpose clear: disposing/stopping the ray tracer engine. This distinguishes it from ray tracer siblings like init and pause_render. The verb (dispose) and resource (ray tracer engine) are specific.

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

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

No guidance is given on when to use this tool vs alternatives. There's no mention of prerequisites (e.g., engine must be initialized first), no distinction between dispose and pause_render (which also stops rendering), and no lifecycle context. An agent must infer when dispose is appropriate.

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