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

With no annotations, the description carries the burden, and 'Retrieve' signals a read-only operation. It also adds meaningful scoping context: only verified solutions are returned, and the scope is the entire Agora square rather than a specific thread or user. Minor gaps like auth requirements or ordering are not addressed, but they are not critical for this simple retrieval.

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 filler and no repeated schema information. Every word contributes meaning.

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 one-parameter read tool, the description plus schema adequately covers invocation. There is no output schema, so the exact return shape is unspecified, but 'solutions' and the tool name strongly imply a list of recent verified 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?

Schema coverage is 100%, and the input schema fully documents the limit parameter with its default and maximum. The description adds no parameter-level detail, but since the schema is complete, this is acceptable.

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 uses a specific verb, 'Retrieve', with a clear resource: recent verified solutions across the Agora square. This clearly distinguishes it from sibling tools such as agora_list_threads and agora_submit_solution, which target different objects and actions.

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 use case is implied: call this when you need the latest verified solutions globally. However, the description does not explicitly state when not to use it or mention alternatives, leaving the agent to infer the appropriate context from the tool name and siblings.

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