Analyze advanced stats for entire roster

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

Annotations already declare readOnlyHint=true, so the agent knows it's a safe read. Description adds minimal behavioral context beyond fetching stats; no mention of rate limits or authorization. It's adequate but not enhanced.

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?

Three sentences: first explains function, second gives use case, third suggests complementary tool. No fluff, front-loaded with purpose.

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?

Despite no output schema, description names the types of stats (Statcast, expected, FanGraphs) and suggests combining with get_team_roster. It covers optional parameters via schema but doesn't elaborate on defaults or response structure. Very functional.

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 coverage is 100% with descriptions for all three parameters. The tool description does not add additional meaning beyond what the schema already provides, meeting the baseline.

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?

Description clearly states the tool fetches advanced stats for the entire roster, specifying Statcast, expected stats, and FanGraphs. It distinguishes from sibling tools like get_player_stats (single player) and get_team_roster (just roster list).

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?

Description gives explicit use cases: daily lineup decisions and identifying underperformers vs. xStats. It also advises combining with get_team_roster. Could further clarify when not to use, but it's adequate.

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