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

Annotations already declare the safety profile (readOnly=false, idempotent=false, destructive=false, openWorld=true), so the description's lower bar is met by adding that the token is temporary and that verification produces a binding. It does not say what happens on verification failure, whether an existing binding is overwritten, or whether the binding is reversible. Useful context, but gaps remain for a non-idempotent write.

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?

Two sentences, no filler, with the core action stated first and the availability precondition second. Every clause carries information the agent needs.

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 non-idempotent write tool with no output schema and two partially undocumented parameters, the description covers purpose and a prerequisite but omits failure behavior, binding lifecycle, and what the caller receives on success. Adequate but leaves real gaps.

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%, so the description must carry parameter meaning. It adds that 'token' is temporary and that the second parameter is an 'agent identifier', which maps to subject_agent_id. It does not explain that subject_agent_id is optional or what value shape either parameter expects.

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 names a specific verb (verify) plus the resource (a temporary Moltbook identity token) and the secondary effect (binding the verified assertion to an agent identifier). This cleanly distinguishes it from the sibling verify_economic_passport, which operates on a different artifact. An agent can select it without opening the schema.

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?

It gives one explicit precondition – 'Available only after the Moltbook developer identity integration is configured' – which is genuine usage guidance. However, it names no alternatives and does not say when to prefer this over verify_economic_passport or what to do if the integration is not set up. Implied usage only beyond the prerequisite.

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