A3.7/5.0

Behavior4/5

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

The annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description adds useful behavioral context beyond annotations by explaining that wait polls missing results for at most 10 seconds and that unavailable risk remains unavailable. It does not cover auth or rate limits, but it meaningfully supplements the annotation profile.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loads the core purpose. Its second sentence is compact but somewhat cryptic, especially "unavailable risk remains unavailable," which could be clearer without adding much length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the essential read-by-ID behavior and the wait polling semantics, and an output schema exists so return values need not be described. However, with low schema description coverage across six parameters, it does not fully explain the optional date filters or response format, leaving clear gaps for an agent invoking the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 17%, so the description must compensate for undocumented parameters. It mentions identification_id, domain, and wait semantics, but leaves to, from, and response_format unexplained, despite those being present in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: "Read one identification card by identification_id in a public domain UUID." It clearly identifies the key lookup inputs and is distinguishable from the listed sibling tools, which cover history, risk scores, webhook signatures, and time.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by "Read one identification card by identification_id," so an agent can infer this is for fetching a single record rather than listing or searching. However, there is no explicit guidance on when to use this versus alternatives or when not to use it.

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