get_player_grade

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds a small extra behavioral detail by noting the grade is 'public' (implying no auth needed) and 'Scout' (indicating the grading source), but it does not disclose behavior around defaults or missing data. This is adequate but not rich.

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, front-loaded sentence with no wasted words. Every term ('Return', 'public', 'Scout', 'player grade') contributes meaning, making it highly concise and well-structured.

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?

Even with an output schema present and safety annotations covering side effects, the description leaves gaping holes: no usage guidance, no parameter semantics, and no context for what week/season mean or what happens when they are omitted. An agent would struggle to call this correctly beyond the simplest case.

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%, and the description provides no parameter meanings. 'Player' is inferable from the resource name, but 'week' and 'season' are completely unexplained, including their default behavior (both default to null). The description fails to compensate for the schema's lack of detail.

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 states a specific verb ('Return') and a specific resource ('public Scout player grade'), which clearly identifies the tool's function. The term 'grade' distinguishes it from sibling tools like get_scout_rankings, get_game_scores, and get_wire_news without needing to name them.

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 guidance about when to use this tool versus alternatives. The description does not mention conditions, prerequisites, or exclusions, and it never references sibling tools like get_scout_rankings for comparative scenarios.

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