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

With no annotations provided, the description carries the transparency burden. It indicates a read-only verification action and a key behavioral trait (not requiring compute work), but it does not explicitly disclose side effects, authorization needs, or error behavior. The single trait adds some value beyond the schema.

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 a single, front-loaded sentence with no wasted words. It efficiently states the core action and key qualifier, making it easy to parse quickly.

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?

The tool has one parameter and an output schema, so the description need not explain return values. However, with no annotations, the description is thin: it lacks usage context, relationship to sibling tools, and any preconditions. It is adequate for a simple verification tool but leaves room for more guidance.

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 compensate for the single parameter agent_id. The phrase 'an agent's inventory hash chain' implicitly ties the parameter to the agent being verified, but it does not explicitly describe the parameter, its format, or constraints. The parameter name is self-explanatory, which mitigates the 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 uses the specific verb 'verify' and names the exact resource ('an agent's inventory hash chain'). It also adds a distinguishing qualifier ('independently of compute work') that differentiates it from sibling tools like verify_chain 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?

The phrase 'independently of compute work' implies a use case, but the description does not explicitly state when to use this tool versus alternatives (e.g., verify_chain). It provides context but no exclusions or alternative references.

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