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

Annotations already declare readOnlyHint, idempotentHint, and closed-world scope, so the safety profile is covered by structured data. The description adds genuinely useful domain context that ESPN source IDs differ from DraftKings IDs, which affects how IDs should be interpreted. It still says nothing about pagination behavior, result volume, or what happens when event_id/athlete_id filters are omitted.

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?

Two short sentences with no wasted words, so it is compact. But it opens with a sentence fragment rather than leading with the operation, and the ID-namespace caveat is buried in second position without framing.

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?

Five optional parameters, no schema descriptions, and no output schema mean the description is the only place an agent can learn how to filter correctly, and it does not cover that. For a tool whose inputs determine whether it returns one event's box score or a broad paginated scan, the definition omits the information needed to call it confidently.

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% across five parameters, so the description must carry the burden, and it largely does not. The ESPN-versus-DraftKings ID note has bearing on how event_id and athlete_id values are interpreted, and 'observed events' hints at event_id, but limit, offset, and sport are never mentioned and it is unclear whether the ID filters accept either ID namespace.

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 team-level scores and box scores attached to observed events, which is more specific than the name alone. However, it is a noun phrase fragment with no verb describing the operation (retrieve/list), and it does not distinguish this tool from the near-identical sibling get_stats_team_games.

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 when-to-use guidance: no mention of choosing this over get_context_player_stats, get_stats_team_games, or get_context_games. The phrase 'attached to observed events' weakly implies a link to event records, but the agent must infer the selection criteria entirely.

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