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

With no annotations provided, the description carries the full burden and does reasonably well: it names the upstream data source (Fantasy Nerds API), states that the week argument is coerced from string or int, and describes what is returned (scores when played, winner when complete). It does not discuss rate limits, auth, or caching behavior, which are minor for a read-only lookup.

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 purpose is front-loaded in the first sentence, but the 'Args:' and 'Returns:' blocks duplicate structured data (the schema defines week, and an output schema already exists). The bulleted return-value inventory is largely restated by the output schema, adding length without new information.

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?

For a single-optional-parameter read tool with an output schema present, the description covers everything an agent needs to call it correctly: the accepted range, the default behavior, and the general shape of the response. It does not need to re-explain return values given the output schema, so the remaining verbosity is a style issue rather than a gap.

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 compensate, and it does: week is documented as 1-18 for regular season plus playoffs, defaulting to null/current week. Minor mismatch: the description claims string input is accepted and converted, while the schema only allows integer or null.

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 opens with a specific verb and resource: 'Get NFL schedule for a specific week or the current week.' It also makes the default/fallback behavior explicit. No sibling tool covers schedules, so there is no ambiguity to resolve, but the purpose is stated cleanly.

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?

It clearly states the selection rule for the single parameter: pass a week to get that week, or omit it to get the current week. That is actionable context for an agent deciding whether to supply an argument. There is no discussion of when a different tool (e.g., matchups or player stats) would be preferable, but none of the siblings overlaps.

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