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

The description falsely claims 'no arguments' while the schema includes an optional processing_role parameter. This misleads the agent about the tool's configurability. No annotations exist to carry safety or side-effect information, so the description must disclose behavior; it fails to mention that the processing role affects output or that the default is 'controller'. The 'no arguments' statement actively contradicts the schema, reducing transparency significantly.

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 relatively concise at four sentences, front-loading the core function and list of templates. The flow moves from what you get to usage ('Fill in [bracketed] sections') to prerequisite. However, the erroneous 'no arguments' phrase wastes space and could be removed, preventing a top score.

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 no output schema and no annotations, the description should clarify what the tool returns (e.g., text, downloadable files) and how the processing role affects the templates. It neither mentions the output format nor explains the role's effect. The false 'no arguments' claim adds confusion. The prerequisite reference is helpful but does not make up for missing critical details about return type and role-driven customization.

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?

Although the schema description covers 100% of the parameter, the tool description says 'no arguments', directly contradicting the existence of processing_role. The description does not add any value to the parameter meaning; instead it actively misleads. This lowers the effective parameter semantics below the baseline for high schema coverage because the misinformation outweighs the schema's clarity.

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 clearly states it retrieves pre-filled GDPR templates, listing specific document types (Privacy Policy, DPIA, ROPA, Data Breach Procedure). It also distinguishes itself from siblings like gdpr_generate_report and check_compliance by focusing on template generation. The verb 'Get' plus resource and scope makes the purpose highly clear.

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?

Provides explicit when-to-use guidance by instructing to 'Run gdpr_check_compliance() first to see which documents you're missing.' This establishes a clear workflow and prerequisite, helping an agent decide when to invoke this tool versus alternatives. It also implies the tool is useful when missing specific documents, which is strong usage direction.

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