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

No annotations are provided, so the description must fully disclose behavior. It states a 60-day window, but the input schema allows a window_days parameter (7-180) which is not explained. There is no mention of output format, pagination, or side effects, leaving important behavioral traits undocumented.

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 two sentences with no filler. It is front-loaded with the core purpose and provides a brief usage hint. Every word earns its place.

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 single optional parameter and no output schema, the description covers the basic purpose but omits crucial parameter semantics. The explanation of when to use is minimal, but overall it provides a functional starting point for a simple lookup tool.

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 0%, so the description must explain parameters. However, it does not mention the window_days parameter at all, and it incorrectly implies a fixed 60-day window, contradicting the schema's range of 7-180. This misleads the agent about the parameter's purpose.

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 lists programs with registration windows opening within 60 days. This is a specific verb+resource (list programs) with a clear time constraint, and it differentiates from siblings since no other tool mentions upcoming registrations.

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 says 'Useful for parents planning ahead,' which implies when to use it, but it does not provide explicit guidance on when not to use it or mention any alternative tools for related tasks.

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