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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavior: the link is publicly openable by anyone holding it, recipients can sign up for email alerts while the transfer is still being checked, and the link's stability for the transfer's lifetime has sharing implications. 'Reading changes nothing' restates readOnlyHint but is not contradictory.

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 purpose is front-loaded in the first clause, followed by lifecycle and sharing context in compact sentences. Most clauses earn their place, though 'the page the website shares' and 'Reading changes nothing' are mildly redundant with the first clause and annotations respectively.

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?

With an output schema for the return value, rich annotations, and a fully documented single parameter, the description only needs to explain what the link is and its exposure risk, which it does. Nothing essential for a correct call is missing, though explicit routing against siblings would complete it.

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?

There is a single parameter (uetr) with 100% schema description coverage plus a strict UUID pattern, so the schema carries the semantics. The description only implies that the UETR identifies a transfer and adds no format or sourcing guidance, which is the expected baseline when schema coverage is complete.

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 opens with a specific verb and resource: 'Get the link to a transfer's public status page', and clarifies it is 'the page the website shares'. An agent can distinguish this from get_transfer or share_payment_record by the 'public status page' wording, though no sibling is named 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?

It implies usage by describing what the link is for and cautioning 'share it only with people who should follow it', which hints at when retrieval makes sense. However, it never states when to prefer this over siblings such as get_transfer or share_payment_record, nor any prerequisites.

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