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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, open-world), so the description's added value is the result taxonomy: pending, done, failed, plus the clarification that 'done' means what arrived on Robinhood Chain and that the answer reflects Trustware's reporting. That is genuine behavioral context an agent would not get from the annotations. It stops short of saying anything about polling cadence or how long a route can stay pending.

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?

It is a single sentence with no filler, which is good, but the sentence is grammatically tangled: the em-dash aside 'what arrived on Robinhood Chain' is nested inside a list inside a colon clause. The core fact (status lookup by intentId) is front-loaded, yet the construction costs readability.

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 no output schema, the description carries the burden of conveying return values, and it does so by naming the three possible statuses and what 'done' signifies. For a one-parameter read it is nearly sufficient; the main omission is any statement about whether a pending result should be retried or how it resolves.

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 with 100% schema description coverage ('The intentId pay_with returned'), so the schema already does the work. The description repeats that the lookup is 'by its intentId' without adding format, validation, or provenance 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?

The description gives a specific verb+resource: it reports the status of a route that pay_with prepared, keyed by intentId, and it enumerates the outcomes (pending, done, failed). It also ties the tool to its sibling pay_with rather than leaving the relationship implicit, though the phrasing 'Where a Pay with route got to' is informal and slightly muddles the front line.

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?

The clause 'once its transaction was sent' gives an implied timing precondition and points at pay_with as the upstream tool, which is useful context. However, it never states explicitly when-not to call it, whether polling is expected while status is pending, or how it relates to sibling status tools like hold_status or account_status.

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