eda_pcb_ray_tracer_engine_init

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the function name, the return type Promise<void>, and that it initializes the engine; it does not disclose side effects, resource allocation, whether it starts rendering, idempotency, or whether dispose is required. The 'ADD since EDA v4' remark adds version context but no behavioral transparency.

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 short and the main purpose is front-loaded, which is good. However, the 'remarks: ADD since EDA v4' line does not help an agent select or invoke the tool correctly, and the overall terseness leaves important behavioral context missing. It is concise but under-specified rather than efficiently complete.

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 tool with no annotations and no output schema, the description should explain the operational context: when initialization is necessary, what it changes, and what lifecycle relationships exist with the many sibling ray tracer engine tools. None of that is present. The high schema coverage covers parameters, but not the behavioral and sequencing context an agent needs.

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 coverage is 100%, so the baseline is 3. The schema already describes args as a JSON parameter array in official signature order and windowId as the target or active window. The description adds no additional parameter meaning, but it doesn't need to because the schema covers both parameters adequately.

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 description states a specific verb ('初始化' / initialize) and a specific resource ('光线追踪引擎' / ray tracing engine), so the core purpose is clear. It also includes the method signature pcb_RayTracerEngine.init(), which identifies this as the initialization entry point. It doesn't explicitly contrast with sibling ray tracer engine tools, but the name and verb already differentiate it from dispose, pause_render, and configuration getters/setters.

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?

There is no guidance on when to call this tool, whether it must precede other ray tracer engine operations, whether it can be called multiple times, or how it relates to sibling tools like eda_pcb_ray_tracer_engine_dispose. The description gives no context about prerequisites or alternatives, so an agent has to guess about ordering and lifecycle.

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