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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the result is unsigned and permissionless, but it does not explain what happens if eligibility conditions are unmet, whether the refund is partial or full per seat, or other state-change implications.

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 a single compact sentence that front-loads the game context and action. It is mostly efficient, though the parentheticals and grammar make it slightly less crisp than it could be.

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?

For a two-parameter prepare tool with full schema coverage and no output schema, the description supplies the key eligibility condition plus unsigned and permissionless traits. It is sufficient for selection, with only minor gaps around failure behavior and refund mechanics.

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 both wallet and gameId are already documented in the schema. The description adds only indirect context through 'every seat of a sealed table' and does not introduce new parameter syntax or constraints.

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 states a specific verb and resource: prepare an unsigned refund for every seat of a Red Dragon table. The condition 'sealed table nobody flipped for a day' makes the operation distinct from siblings such as prepare_red_dragon_flip, join, and leave, though the phrasing is slightly awkward.

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?

It clearly gives the triggering condition: a sealed table where nobody flipped for a day. It also states 'Anyone may send it,' clarifying permissionless usage, but it does not explicitly name alternative tools or when not to use this one.

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