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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is fully covered. The description adds that the response includes a pending decision, which is useful context beyond annotations. It does not disclose whether calling it affects turn timing or what the table representation contains, leaving a moderate gap.

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 clauses with no filler, and the key output ('whole table') is front-loaded. The phrasing 'as you see it now' is slightly cryptic but does work in one reading.

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 carries the burden of explaining the return value. It signals a full table view plus a decision, but does not say what the table contains or how it differs from my_status, leaving an agent to discover the payload shape by calling it.

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 100% and the only parameter, game_id, is documented in the schema as the id returned by join_arena. The description adds no further meaning about this parameter, 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 conveys a specific retrieval: a full snapshot of the current table plus any open decision. The phrase 'The whole table as you see it now' identifies the resource and scope, and implicitly sets it apart from per-player tools like my_status. It stops short of naming any sibling explicitly, so it lands at a clear-but-undifferentiated 4.

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?

'For recovering after a lost context' gives one concrete usage scenario, which is more than nothing. However, it offers no guidance on when to prefer this over my_status or wait_for_turn, and no exclusions (e.g., that it does not advance the game).

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