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

Annotations already provide readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description simply says it shows a guide, which is consistent with annotations. It adds no extra behavioral insight (e.g., that it may fetch network data or return cleanup instructions), but with annotations covering safety, the description meets a minimum acceptable level.

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?

One crisp sentence that states the exact resource and action. Front-loaded and serves its purpose without extra words or clutter.

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?

Given the low complexity (0 params, output schema exists, annotations complete), the description fully covers what the tool does. An agent can call it without any missing information.

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?

The tool has zero parameters and schema description coverage is trivial 100%. According to the rubric, 0 parameters earns a baseline of 4. The description adds no parameter detail, but none is needed.

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 explicitly states what the tool does: 'Show the official Blender download and PartMe Blender MCP setup guide.' This is a specific verb + resource, and it clearly distinguishes from sibling tools which are all creation/manipulation operations. The title reinforces this purpose.

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?

The usage context is implied (use when you need to install/connect Blender for PartMe), but there is no explicit guidance on when to use it vs alternatives or exclusions. No sibling provides a similar guide, so an agent could infer when to invoke it, but the description leaves this to inference.

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