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

No annotations are provided, so the description carries the full behavioral burden. It implies a read/list operation and explains the B-rated status, but does not state auth requirements beyond the schema, return format, pagination, rate limits, or whether the operation has side effects. The domain context is useful but operational transparency is limited.

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 description is a single, front-loaded sentence with no wasted words, covering status meaning, optional filter, and intended signal. The leading 'PRO.' is slightly ambiguous and could be clearer, but overall structure is efficient.

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 annotations and no output schema, the description should provide more operational context. It covers purpose and the optional town filter, but omits return shape, auth expectations, and any behavioral details an agent would need beyond the partial schema. For a query tool with an undocumented town parameter, this is thin.

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 50%: access_token is documented in the schema, while town is not. The description adds meaning for town by saying it is optional and acts as a filter, which partially compensates for the schema gap, but it does not specify town format (name, code, etc.). The access_token parameter is covered by the schema and needs no further elaboration.

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 clearly identifies the resource and filter: sponsors currently B-rated, with optional town filtering. It also clarifies what B-rated means in this domain (downgraded, on an action plan). It does not explicitly differentiate itself from sibling tools such as sponsor_search, but the status-specific scope is distinct enough for an agent to understand its purpose.

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 phrase 'compliance risk signal' hints at a use case, and 'optionally by town' indicates a filtering option. However, there is no explicit guidance on when to use this tool versus siblings like sponsor_search or sponsor_check, nor any exclusions or prerequisites. An agent must infer usage context.

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