v2.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the read-only nature, which is a key behavioral trait. However, with no annotations provided, it does not mention other important details like permissions, error handling, or response behavior.
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 concise sentence that front-loads the core action. However, it sacrifices completeness, particularly for parameter documentation.
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?
Given the tool's simplicity and lack of output schema, the description is minimally adequate but omits details about the response format and the access_token parameter, leaving gaps for an agent.
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?
The description adds meaning to the 'offer_id' parameter by identifying it as the 'DPS ID', but completely ignores the 'access_token' parameter. With 0% schema description coverage, more explanation is needed.
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 action ('look up'), the resource ('offer item'), and the identifier ('by its DPS ID'), and notes it is read-only. This distinguishes it from siblings like list_offer_items and update_offer_item.
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 description implies usage for read-only retrieval of a single item, but does not explicitly state when to use this tool over alternatives (e.g., list_offer_items for multiple items) or conditions for use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
