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

Adds real value beyond the annotations: the request is asynchronous and returns no link until the owner confirms, notification is by email, and re-asking with identical settings returns the open request while different settings replace it — matching idempotentHint=true. It never explains the destructiveHint=true side effect in terms of what happens to an already-shared link when a new request replaces the old, which is the one meaningful gap.

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?

Front-loaded with what is requested and the blocking confirmation requirement, then the idempotency rule and the authorization constraint. Mostly dense, though 'The owner sees the request on the website' partly repeats the preceding sentence and could be folded in.

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?

An output schema exists and the description still usefully points to list_pending_access for the eventual link, plus the confirmation/notification flow and the auth restriction. It is nearly complete for a three-parameter mutation, missing only the fate of an existing share link when a request is replaced.

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%, so uetr, show_fees, and show_commentary are already documented, including the 'leave out to keep current setting' semantics. The description's phrase 'same settings' hints that the booleans drive replacement vs. reuse but adds no new syntax or format detail.

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 and resource: request the payment record link of a paid transfer for sharing bank reports. It is clearly distinct from get_payment_record (fetch the record) and get_share_link, and names the async request/confirm model up front.

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?

Gives the operational context explicitly: only the account owner's API keys and connected apps can ask, the owner must confirm on the website, and list_pending_access is the retrieval path once confirmed. It does not explicitly contrast with get_share_link, so an agent must infer which of the two to call first.

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