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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so 'Read only' is pure repetition. The only added signal is 'with status', which vaguely suggests a status field per item, but nothing about ordering, pagination, or whether history is bounded.

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?

Two short fragments, front-loaded with the resource. It is efficient, though the second fragment ('Read only') spends space on information already carried by the annotations.

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 zero-parameter read tool with no output schema, the description should at least sketch what comes back — status values, date coverage, or pagination. 'With status' gestures at the payload but leaves the agent guessing about the shape and recency of results.

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?

The tool takes zero parameters, so the baseline is 4; there is no argument semantics for the description to compensate for. Nothing in the description contradicts or misleads about the empty 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?

The phrase 'Withdrawals from the wallet to the bank, with status' identifies the resource and hints at the returned field, but it is a noun phrase with no explicit verb and no differentiation from near-siblings like list_digital_account_transfers, list_operations, or get_statement. An agent can guess the direction (wallet → bank) but not precisely why this list exists versus those.

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?

There is no statement of when to use this tool, what time window it covers, or which alternative to pick for statements/transfers. 'Read only' restates the annotation rather than providing usage context.

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