Get PCB 3D view and rendering status

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description usefully enumerates what kinds of data come back (camera angles, layer visibility, export capability), which matters since there is no output schema, but it does not explain the idempotentHint=false signal or whether the viewport shortcuts mutate view state.

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?

A single dense sentence with no filler, front-loading the returned data categories. The list structure is readable, though the mixed bag of items (view data plus export support plus shortcuts) slightly muddles what the tool primarily does.

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 read-only tool with a nested target object, no required parameters, and no output schema, the description covers return-value categories but omits how 'target' selects the document and what the 'shortcuts' actually are or do. Adequate but with clear gaps given the complex nested schema.

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 only 33%: only viewAngle carries a schema description, while the entire nested 'target' object (tabId, pageId, projectId, documentId, fingerprint, etc.) and timeoutMs are undocumented. The description adds nothing about any parameter, so it fails to compensate for the low coverage.

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?

States a specific verb ('Retrieves') and enumerates concrete resources: 3D camera angles, layer visibility, STEP/OBJ export support, and viewport shortcuts. However, it never distinguishes itself from close siblings like easyeda_get_pcb_3d_inspection or easyeda_export_3d_model, so an agent cannot tell from the description alone which one to pick.

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 when-to-use guidance at all — no condition indicating whether this is for inspecting the live view versus exporting a model, and no reference to the similarly-named 3D inspection sibling. The agent must infer intent purely from the name overlap.

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