solidworks_active_document

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

The description explicitly states 'without changing it', reinforcing the non-mutating behavior already indicated by annotations. No side effects or error conditions are described, but the annotations cover the key behavioral guarantees.

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 concise sentence with no filler, front-loaded with the action and resource. Every word contributes useful meaning.

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 simple read-only tool, the description is sufficient: it states what is returned and that no mutation occurs. It could mention behavior when no document is active, but this is a minor gap given the annotations and sibling context.

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?

There are no input parameters, so no parameter clarification is needed. The description names the output fields, which helps set expectations even though the output schema is not detailed here.

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 'Return', specifies the resource 'active document', and lists the exact data fields returned. This clearly distinguishes it from connect/open/modify tools.

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 phrase 'without changing it' implies read-only inspection, but there is no explicit guidance on when to use this tool versus alternatives. Usage is implied rather than stated.

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