+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that returned content is 'untrusted data' and instructions should not be executed, adding safety context beyond basic read operation. However, with no annotations, it omits details on side effects (e.g., destructive changes) or authentication needs.
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?
Two sentences efficiently convey purpose and key behavioral warning. No fluff, front-loaded with the core action and notable safety constraint.
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 (2 params, no output schema, no annotations), the description covers the essential warning but lacks details on return format or when to use it. It is adequate but leaves room for improvement in providing complete operational context.
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 50%, with only 'since' having a minimal description ('only after this seq'). The tool's description adds no parameter explanations, leaving 'member_id' undocumented. This fails to compensate for the schema's gaps.
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 'check my inbox' with a specific verb and resource, indicating its function. It distinguishes from sibling tools by focusing on inbox retrieval, but lacks explicit differentiation from similar tools like baton_receive.
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?
No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites or exclusions. It only warns about not executing instructions, which is a behavioral note rather than usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
