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 fully covered without the description. The description contributes nothing beyond that — no mention of result shape, ordering, pagination, or whether the counterparty must exist — and its only addition, the describe_operation pointer, is marginal.

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 short, but the first sentence is stated twice verbatim, which is pure waste rather than concision. The only useful content, the operation ID and describe_operation pointer, is buried at the end instead of front-loaded.

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, undocumented nested/free-form query parameters, and hundreds of near-duplicate sibling tools, the description should clarify return contents and disambiguation. It instead supplies only a URL and a schema-lookup pointer, which is inadequate for correct invocation.

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 0% across two parameters, so the description carries the full burden and fails it entirely. It never mentions the required path parameter `id` (a counterparty identifier) nor the free-form `query` object, leaving an agent to guess what filtering is possible.

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 is a verbatim duplication of the endpoint path in the tool title, which is a tautological restatement of the name rather than an explanation. An agent can infer 'list notifications for a counterparty' from the URL, but the description itself adds no articulation of what is returned or how it differs from siblings like get_counterparties_by_id_notices.

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 versus alternatives such as get_notifications or get_counterparties_by_id_notices, nor any prerequisite or pagination guidance. The only actionable cue is the pointer to describe_operation, which is about fetching schemas, not about choosing this tool.

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