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

With no annotations, the description carries the full burden; it does disclose the three verification dimensions checked (schema, signatures, log inclusion), which is meaningful behavioral context. However, it says nothing about what happens on failure, whether verification has side effects, or what prerequisites (trust roots, network access to a log) are needed.

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 sentence, front-loaded with the action and inputs, followed by the report content. No filler or redundancy.

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 tool with no annotations, no output schema, and a free-form nested object parameter, the description covers the core purpose and the high-level checks performed. It leaves gaps around the shape of the signed object, failure reporting, and precedence between the two input modes, which an agent must guess.

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 coverage is 0%, so the description must compensate. It usefully signals that 'eid' and 'object' are alternative input modes ('by EID, or any signed Open Entity object'), but it does not state precedence when both are supplied, that neither is formally required, or what structure the nested 'object' is expected to have.

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?

Names a specific verb (Verify) and its two accepted input forms (EID or signed Open Entity object), and states what it reports back: schema, signatures, and log inclusion. That is distinct from retrieval siblings like openentity_read or openentity_resolve, though it does not explicitly contrast itself with them.

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?

There is no when-to-use guidance, no mention of when verification is unnecessary, and no reference to sibling tools such as openentity_find or openentity_resolve. The intended scenario (checking a signed object's integrity and log inclusion) must be inferred from the purpose sentence alone.

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