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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds a useful caveat that ESPN source IDs are separate from DraftKings IDs, which helps avoid ID namespace confusion, but it does not explain pagination, filter combination behavior, or what the returned scores/box scores include.

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 short sentences with no filler, and the key ID caveat is stated directly. However, the first sentence is a fragment rather than a front-loaded verb phrase, which slightly weakens clarity.

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 query tool with five optional parameters, no required fields, 0% schema coverage, and no output schema, the description is too thin. It should explain how event_id, athlete_id, sport, limit, and offset shape results, and ideally clarify whether this returns game-level context only or also athlete/team breakdowns.

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 for five undocumented parameters. It only hints at ID-namespace semantics via 'ESPN source IDs are separate from DraftKings IDs,' but does not explain event_id, athlete_id, sport code format, limit, or offset, leaving most parameter meaning unstated.

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 identifies the resource as games with scores and box scores, but it is written as a noun phrase rather than a clear verb-led statement of what the tool does. It does not distinguish this tool from sibling get_stats_games, which likely also returns game-level data.

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 explicit guidance on when to use this tool versus get_stats_games, get_context_player_stats, or get_context_team_stats. The term 'context' implies supplemental data, but the agent must infer the selection criteria from the name alone.

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