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 no behavioral context such as what the certificate represents, whether data is validated, or how unacceptable risk is handled.

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 a single bracketed phrase and is too terse for a tool with three required parameters and compliance implications. Its brevity does not earn its place because critical action and usage context are missing.

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 three-parameter compliance tool with no output schema, the description is not complete enough: it does not explain what a certificate is, how intended_purpose is used, or what the agent should expect as a result. Annotations cover the safety profile but not the domain behavior.

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 0%, and the description does not explain system_id, risk_category, or intended_purpose. The risk_category enum values are left undocumented in prose, so the description does not compensate for the schema gap.

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 names a resource, "EU AI Act compliance certificate," and adds a [security] tag, but it uses a noun phrase with no verb. It does not clarify whether the tool checks, retrieves, or issues a certificate, though the EU AI Act focus distinguishes it somewhat from generic compliance siblings.

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 versus compliance_check, compliance_explain, compliance_fairness, or other compliance siblings. No prerequisites, exclusions, or alternative-selection criteria are provided.

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