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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether this is a read-only lookup or a state-changing certificate issuance, not permission or auth requirements, not what is returned or persisted. A six-word label for a three-required-parameter operation is inadequate.

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?

It is short with no wasted words, but this is under-specification rather than conciseness; a six-word noun phrase for a required-parameter compliance tool leaves the agent with almost nothing to act on.

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?

With no output schema, no annotations, three required parameters at 0% coverage, and only a bracketed category tag plus a noun phrase, the definition is nowhere near complete enough for an agent to invoke it 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?

Schema description coverage is 0% and the description names none of the three required parameters (system_id, risk_category, intended_purpose). The enum on risk_category is self-evident from the schema, but the semantics of system_id and intended_purpose — formats, where they come from, how they affect the certificate — are documented nowhere.

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 phrase "EU AI Act compliance certificate" is essentially a restatement of the tool name with the noun "certificate" added; there is no action verb to say whether it issues, verifies, or looks up a certificate. Nothing distinguishes it from close siblings such as compliance_check, compliance_explain, or drift_certificate. It borders on tautology with only a faint hint of the resource area.

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 when-to-use guidance, no prerequisites, and no mention of when an agent should pick this over compliance_check or the other compliance_* siblings. The only implicit signal is the EU AI Act domain, which is not enough to route an agent correctly.

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