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

No annotations are provided, so the description carries the full disclosure burden. 'Get' implies a non-mutating read, but it says nothing about error behavior for unknown ids, whether the list must be finished/verified to return meaningful data, or what the returned 'details' comprise.

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?

One sentence, front-loaded with the verb and resource, with no filler. It is appropriately sized for a one-parameter lookup, though it is terse enough that any added context was clearly cut rather than omitted for brevity.

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 simple single-entity read with 100% schema coverage and no output schema, the definition is minimally adequate. The absence of an output schema means the description should ideally sketch what 'details' are returned, and it does not.

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 100% and the single parameter list_id is fully documented in the schema, so baseline 3 applies. The description only restates 'by its id' and adds no format, source, or lookup guidance beyond the schema.

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?

States a specific verb ('Get') and resource ('details of a single bulk verification list'), scoped to one entity by id. It distinguishes itself implicitly from the sibling list_lists by emphasizing 'single', but never names or contrasts that sibling explicitly.

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?

'By its id' implies you must already have a list_id, which hints at the post-creation/post-listing retrieval workflow. However, there is no explicit when-to-use statement, no mention of list_lists as the way to obtain the id, and no exclusions.

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