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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds genuine content disclosure beyond that: unpublished drafts are returned and a related 'raise' is embedded when present. It says nothing, however, about what happens with an unknown slug or how large the returned payload is.

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 short sentence with no filler; the scope caveat (drafts too) is placed immediately after the main clause. Minor deduction because the wording is clipped and domain jargon like 'raise' and 'as stored' is left unexplained.

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 is the only signal about return content, and it only gestures at it ('with its raise if it has one') without listing fields or indicating failure behavior for a missing slug. Adequate for a simple single-record read, but thinner than a no-output-schema tool warrants.

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 single 'slug' parameter is already documented with an example URL format, so the description need not explain it. The description contributes no additional detail about slug format, case sensitivity, or slug-vs-id confusion, so the baseline 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?

The description identifies the object ('one of the player's games as stored') and adds two scope details (drafts included, raise included), but it is a noun phrase with no verb and never distinguishes this from close siblings like check_game, get_game_facts, list_games, or search_games. An agent can infer it fetches a single game, but the boundary against neighbours is left to guesswork.

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 when-to-use guidance and no named alternative. Nothing tells the agent whether to prefer this over check_game (validation) or get_game_facts (facts), nor what condition selects the list/search variants instead.

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