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

The description adds crucial context beyond the annotations: it specifies that these are global calendar periods, not records of actual agency submissions, and warns that a listed period does not imply complete data coverage. This prevents misinterpretation of the returned data and is highly valuable for an agent.

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 front-loaded with the purpose and then adds necessary clarification. It is slightly repetitive (listing deadlines then detailing date types), but every sentence contributes to understanding and none is wasted.

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?

The tool is simple with no parameters and an output schema. The description fully explains what the tool returns, the meaning of the periods, and important caveats, leaving no significant gaps for an agent to call it correctly.

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 tool has zero parameters, so the baseline is 4. No parameter information is needed, and the description does not introduce any confusion about parameters.

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 'List' with a clear resource 'reporting calendar and submission/certification deadlines'. It immediately tells the agent what the tool does and distinguishes it from sibling tools that deal with awards, agencies, or transactions.

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?

There is no explicit guidance on when to use this tool versus alternatives, nor any mention of prerequisites or conditions for use. The caveat about what the data is not is behavioral transparency, not usage guidance.

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