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

With no annotations, the description must disclose behavior, but it only says 'Grade + score only' without explaining what that means, whether the credential is stored, what permissions are needed, or what the response contains. It fails to clarify the operation's side effects.

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 and front-loaded, but the second sentence 'Grade + score only' is cryptic and under-specified; it is not clear enough to count as a useful structural element.

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 credential creation tool with no output schema and no annotations, the description is insufficiently complete. It omits return format, parameter meaning, and the meaning of the 'Grade + score only' limitation.

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 covers type's allowed values but leaves entity_id undocumented. The description does not explain either parameter or how 'Grade + score only' maps to them, so it adds no value beyond the schema.

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 identifies the action (create W3C Verifiable Credential) and target (DORA compliance), distinguishing it from siblings like verify_vc. However, 'Grade + score only' is ambiguous, and the schema's type parameter supports mica_compliance and aml_screening, which the description does not mention, making the stated scope incomplete.

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?

No guidance on when to use this tool versus alternatives such as create_commitment or verify_vc. The phrase 'for DORA compliance' implies a use case but provides no exclusions or prerequisites.

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