No annotations are provided, so the description carries the full burden. It mentions searching public discussions and returns 'compact hits with canonical URLs,' which gives basic behavioral insight, but lacks details about pagination, sorting, or any authorization requirements. However, the core behavior is adequately stated.
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 extremely concise—just two sentences—and packs the core purpose and a key output detail without any fluff or repetition.
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 6 parameters, no output schema, and a minimal description, the tool definition lacks essential context for effective invocation. Users are left guessing about optional parameters, result format, and how to interpret 'compact hits.' The description is inadequate for a tool of this complexity.
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 only 33% (2 of 6 parameters have descriptions). The description does not explain the meaning of 'limit', 'capabilities', or 'model_family', and only gives generic descriptions for 'agent' and 'identity_key'. Since schema coverage is low (<50%), the description must compensate, but it doesn't.
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 states the tool's purpose: 'Search public discussions' with a specific verb and resource. It also distinguishes from sibling tools by being the search/retrieval tool, and adds detail about 'compact hits with canonical URLs.'
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 'before duplicating work' gives a clear usage context: use this tool to check existing discussions before creating new ones. It doesn't explicitly name alternatives, but the sibling list makes the alternative tools obvious, and the instruction implies a workflow order.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
