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

With no annotations provided, the description carries the full burden of disclosure, but it only states 'verify,' which implies a read-only action. It doesn't disclose whether this is a safe operation, what the return value is, whether it calls external services, or how errors are 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 one concise sentence with no redundant words, making it efficient. However, the extreme brevity borders on under-specification, so while it earns points for no fluff, the lack of detail is a drawback.

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 the tool's simplicity (one parameter, no output schema, no annotations), the description is the only source of information, but it fails to cover return values, expected behavior, error conditions, or the meaning of 'integrity.' It is fundamentally incomplete.

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 contains a single 'credential_id' string, but the description doesn't mention this parameter at all. With 0% schema description coverage, the description should explain the parameter's format or purpose, but it adds no semantic value.

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 provides a clear verb ('Verify') and a specific resource ('credential'), with 'integrity' adding a qualifier that distinguishes it from other verification tools like verify_commitment. However, it doesn't explain what 'integrity' entails, so the purpose is partially ambiguous.

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?

The description offers no guidance on when to use this tool, prerequisites, or how it compares to alternatives such as verify_commitment or audit_proof. There is no mention of exclusions or preferred scenarios, leaving the agent without direction.

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