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

No annotations are provided, so the description carries the full burden of disclosing behavior. It does add useful context such as 'Reference-grade implementation' and 'Wire format normative; production-grade is Layer B,' which hint at implementation quality and format stability. However, it does not disclose side effects, return structure, or any safety profile, leaving gaps in behavioral transparency.

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 concise, using four short sentences that front-load the primary purpose and then add context. There is no redundant or extraneous wording, and every sentence contributes useful information.

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 (no parameters, no output schema), the description is reasonably complete: it explains what is returned (metadata for all claims) and when to use it (agent introspection). It could benefit from a hint about the return format, but the additional context about wire format and production-grade partially compensates for that gap.

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?

With zero parameters, the schema has no semantic burden, and the description does not need to explain parameters. The baseline for no parameters is 4, and the description does not detract from that.

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 clearly states that the tool returns HiveAttest layer/spec/patent metadata for all claims, which is a specific and distinct purpose among the sibling attest tools. It uses a concrete verb ('Return') and identifies the resource (metadata) and scope (all claims), making it easy to distinguish from other attest operations.

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 provides a clear usage context by stating 'Useful for agent introspection,' which tells the agent when to consider this tool. However, it does not explicitly mention when not to use it or name alternatives, so it falls short of the top score.

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