Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, and it does add real behavioral value by enumerating the five result states (ok/tampered/expired/superseded/unknown). However, it doesn't state that verification is read-only, whether it requires network/auth, what a malformed receipt triggers, or how those states are surfaced in the response.
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?
One short sentence, front-loaded with the action and resource, with the outcome enumeration doing useful work. Nothing is padded or redundant.
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 verification tool with a nested object parameter, no annotations, and no output schema, the description is too thin. It doesn't explain the expected receipt structure, how outcomes map to the return value, or error behavior, leaving the agent to guess at invocation details.
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 single required 'receipt' parameter is a nested object with 0% schema description coverage, and the description only says it is a 'signed verdict receipt'. It gives no information about required fields, signature format, encoding, or what makes a receipt valid, so it fails to 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 states a specific verb ('Verify') and resource ('signed verdict receipt') and enumerates the possible verdicts, so an agent knows exactly what the tool does. It implicitly distinguishes itself from siblings like verify_attestation by naming the receipt as the object, though it doesn't explicitly route away from verdict_query or verify_attestation.
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 alternatives such as verify_attestation or verdict_query. The outcome list hints at validation use but doesn't state preconditions, when-not-to-use cases, or which sibling handles attestations instead.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
