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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds a useful hint that a freshness/staleness field is returned, but says nothing about failure modes for non-live games or data latency beyond that term.

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?

One compact sentence with the resource up front and the returned fields enumerated after the colon; no filler. The colon list is dense but readable.

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 no output schema, the description does the work of naming the return fields (score, situation, latest play, freshness), which is exactly what an agent needs. Only gap is the lack of guidance about non-live games and error behavior.

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% and the gameId description already routes to aura_list_games/aura_live_games as the id source. The description adds no further meaning to the single parameter, so the baseline of 3 applies.

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 resource (current game state) and enumerates the contents: score, situation, latest play, freshness. An agent can distinguish it from the heavier aura_boxscore or aura_game_plays by the explicit field list, though no sibling is named.

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?

'At this moment' implies live/in-progress usage, but the description never says when to pick this over aura_get_game, aura_boxscore, or aura_game_plays, nor what happens for a scheduled or finished game.

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