send-arcade_playGame

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

No annotations are provided, so the description carries the full burden. It only states that an entry fee is paid via transaction, but does not disclose other behaviors such as whether the game is non-deterministic, what happens on failure, or any state changes. This is insufficient for a mutate tool.

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 extremely concise at one sentence, but it conveys the core action. However, it could be better structured to include more detail without being verbose, such as mentioning that the function is a write operation.

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?

Given the tool involves a transaction with at least three parameters and no output schema, the description lacks many crucial details: what happens after the game, how to interpret results, error handling, and return value. This is incomplete for an agent to use effectively.

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?

The input schema already describes 'wallet' and 'betAmount', but 'gameId' lacks description. The tool description adds no parameter-specific details beyond the schema, failing to compensate for the missing description of 'gameId'.

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 specifies the action 'Enter and play a game' on Send Arcade, which clearly indicates the tool's purpose. It is distinct from the sibling 'send-arcade_listGames' which is for listing games, but it does not explicitly differentiate from other tools.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, when not to use it, or any conditions that would make another tool more suitable.

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