arcium_play_coinflip

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It mentions encryption and MPC randomness but fails to disclose what happens after the comparison (e.g., result output, need for decryption). Insufficient for a game 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?

A single sentence that is front-loaded with the key action. No wasted words, achieving high conciseness while conveying the essential functionality.

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 there is no output schema, the description should indicate what the tool returns (e.g., win/loss status). It does not, leaving the agent uncertain about the tool's outcome. Inadequate completeness for a simple but interactive tool.

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 single parameter (choice) is well-defined in the schema with an enum and description. The tool description adds no additional meaning beyond the schema's 'Your choice' description, so baseline score of 3 is appropriate.

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 clearly states the action ('Play an encrypted coin flip') and the resource ('coin flip'), distinguishing it from sibling tools like arcium_play_rps by mentioning encryption and MPC randomness. However, it could be more explicit about the outcome of the flip.

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 implies usage context (encrypted, MPC randomness) but does not provide when-not-to-use or compare with alternatives such as arcium_play_rps. No prerequisites or exclusions are mentioned.

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