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

With no annotations, the description carries the burden of behavioral disclosure. It discloses that the returned token is good for one move and that the seat includes current options and the last refusal, but it does not explicitly state whether calling this tool is read-only, whether it consumes anything, or what happens if the token is already used.

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 two sentences with a front-loaded colon list of returned contents. Every clause earns its place: what the seat contains, when to read it, and the single-use nature of the token. There is no filler or redundancy.

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?

There is no output schema and no annotations, so the description must be self-sufficient. It explains the main returned fields and token lifecycle, but it omits parameter guidance and does not explicitly state that the call is a read operation, nor does it differentiate itself from poker_hands or other related poker tools.

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 0% and the description never mentions the required owner or tableId parameters. The parameter names are somewhat self-explanatory, but the description does not explain how to supply them, what owner refers to, or how they map to the 'your seat' concept.

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 identifies the resource as the caller's seat at a table and enumerates the contents returned: cards, legal actions, turn token, last refusal, and table. It lacks an explicit verb like 'get' or 'retrieve', but the instruction to read it before every move signals that this is a state-query tool and distinguishes it from action tools like poker_act.

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 explicitly says when to use the tool: 'Read this before every move.' It does not name sibling alternatives such as poker_act, poker_hands, or poker_tables, nor does it provide exclusion criteria, but the timing guidance is actionable and clear.

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