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

The annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only a "[security]" category tag and says nothing about what the report contains, what data it reads, or any permission requirements. It does not contradict the annotations, but it adds minimal behavioral context.

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, but its brevity reflects under-specification rather than efficiency. It is not front-loaded with actionable information and contains no useful detail beyond the title and a category tag.

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 requiring three parameters with no output schema and no parameter descriptions, the description is completely inadequate. It does not explain what the transparency report returns or clarify the required inputs, leaving an agent unable to invoke the tool correctly.

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 input schema has three required parameters (system_id, period, include) with 0% description coverage, and the tool description provides no parameter guidance. It does not explain what system_id identifies, the expected period format beyond the schema's example, or what values are valid for the include array.

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 "[security] Transparency report" essentially restates the title "Compliance Transparency" with a category tag. It gives no specific verb, resource, or scope, and offers no way to distinguish this tool from the many compliance_* siblings such as compliance_check or compliance_oversight.

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 use this tool, when not to, or which alternative to choose. With numerous sibling tools like compliance_check, compliance_incidents, and compliance_oversight, the description leaves selection entirely to inference.

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