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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered without help. The description adds value by naming the returned fields, but since no output schema exists it should say more — whether status is terminal, whether the call is safe to poll, and how 'amount charged' behaves on repeated reads.

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, listing outputs in a natural order. Nothing is redundant or padded.

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 one-parameter read-only lookup this is nearly sufficient, and naming the return fields partly compensates for the absent output schema. It stops short of describing the status lifecycle or how this relates to verification_result, which an agent polling for completion would want.

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 100% and the verification_id field already explains its provenance and 3-64 character bounds. The description only adds the 'standalone' qualifier, which hints at which kind of verification id is valid but does not add format or sourcing detail 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 ('verification status') and enumerates what comes back: status, graded citation counts, and amount charged. The word 'standalone' implicitly separates it from run-scoped siblings, though it never names verification_result or run_status to make the contrast explicit.

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?

Usage is only implied: the single parameter is documented in the schema as 'A verification id returned by verify_citations', so an agent can infer this is the follow-up call. There is no explicit statement of when to prefer this over verification_result or run_status, and no guidance on polling versus one-shot lookup.

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