Send-arcade Play Game

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

The description adds behavioral context beyond annotations: it states the tool 'pays entry fee via transaction,' indicating a financial cost. Annotations set destructiveHint=false, but the spending nature is disclosed. However, it does not detail post-game outcomes or irreversibility.

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 somewhat verbose and includes extraneous information ('SAP MCP context: Protocol send-arcade; operation class write'). It can be shortened without losing meaning. The core purpose is clear but padded.

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?

The description lacks guidance on return values (although an output schema exists), error handling, or prerequisites like wallet funding. For a game-playing tool involving transactions, more completeness about flow and consequences is expected.

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 all three parameters ('gameId', 'wallet', 'betAmount') have descriptions in the schema. The tool description adds no further parameter details beyond the schema, meeting the baseline for high coverage.

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 tool's purpose: 'Enter and play a game on Send Arcade (pays entry fee via transaction).' It specifies a verb ('enter and play') and a resource ('game on Send Arcade'), and it distinguishes itself from the sibling tool 'send-arcade_listGames' which lists games.

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 context for when to use the tool ('Use for Send Arcade game listing and play flows') and includes a cautionary note ('Confirm account, wager or spend, and game rules before writes'). However, it does not explicitly state when not to use it or provide alternatives beyond the sibling tool list.

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