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

With no annotations, the description carries the full burden of disclosing behavior. It provides no information about side effects, return values, security implications, or operational characteristics. The cryptic phrase does not explain what the tool does or how it behaves.

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 extremely brief but fails to be effective. It is under-specified rather than concise, providing no useful information. The phrase is cryptic and does not earn its place as a meaningful description.

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 complete lack of annotations, output schema, and parameters, the description is the only source of information. It is entirely inadequate for an agent to understand what the tool does, when to invoke it, or what to expect. The tool is likely a placeholder or severely underspecified.

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 tool has zero parameters, so the description does not need to explain parameter usage. The baseline of 4 applies because there is nothing to clarify; the schema is empty and the description adds no parameter-related details, but there is no deficiency in that regard.

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 'Earned rate + ML-DSA-87 signature' is vague and does not state a clear verb or resource. It mentions concepts but fails to specify what the tool does, leaving its purpose ambiguous. It is not a tautology but lacks any actionable clarity.

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 is provided on when to use this tool versus its siblings (verify_settlement, venue_state, etc.). There is no mention of context, conditions, or alternatives, leaving the agent without any routing information.

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