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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds only that data spans one or all seasons; it says nothing about the browser-side filtering behavior noted in the schema, pagination, or result shape. With annotations carrying the safety burden, this is adequate but thin.

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?

A single tight sentence with the resource and scope front-loaded, followed by the mlb_discovery pointer. No filler or redundancy.

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?

With an output schema present and annotations covering the safety profile, the description only needs to convey purpose and scope, which it does. It is nearly complete, missing only explicit sibling differentiation and any pagination nuance.

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 100%, so the schema already documents all six parameters including sort, team, limit, offset, season and sort_dir. The description echoes the season/team concepts but adds no format or syntax detail beyond the schema, which is the expected baseline when structured fields do the work.

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?

States a specific verb (Fetch) and resource (Baseball Savant team Sprint Speed rows), and the 'team' qualifier implicitly separates it from the player-level mlb_statcast_sprint_speed sibling. It does not explicitly name that sibling to reinforce the distinction, so it falls just short of a 5.

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 gives scope ('one season or all seasons, optionally filtered to a team') and points to mlb_discovery for exact sort/team values, which is a useful routing hint. However, it never states when to prefer this over the player-level sprint speed tool or what conditions make it the wrong choice, leaving usage largely implied.

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