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

Annotations already disclose that this is non-read-only, non-idempotent, and non-destructive. The description adds only the HTTP method and path, which is marginal. It does not explain what the verification mutates or records, what permissions are required, or what happens on failure.

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?

A single, front-loaded sentence with zero filler. Every word contributes to identifying the operation.

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?

There is no output schema, and the description does not describe the response, required body contents, or request context. For a POST verification tool with many siblings, this leaves meaningful gaps for correct invocation.

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 body parameter is 100% described in the schema, but the description only says to consult the OpenAPI schema resource, adding no semantic detail about the body. With a single documented parameter, the baseline of 3 is appropriate.

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 gives a specific verb ('Run') and resource ('permission-circuit gate verification') plus the HTTP endpoint, which is more informative than a tautology. It does not, however, differentiate this tool from close siblings like affix_circuit_verify or affix_verify, leaving an agent to infer the distinction.

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 when-to-use, when-not-to-use, or alternative-tool guidance is provided. An agent is left to guess whether this is the right verification call among the many affix_* verify tools.

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