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

No annotations are provided, so the description carries the burden. It discloses that chips are atomic USDC, raked per hand, and that tableId shows one table as everyone sees it — never a hidden card. It also says 'Free.' However, it does not disclose whether this is a read-only listing, whether it creates or mutates anything, or what the response contains. The behavioral traits disclosed are useful but incomplete for a tool with no annotations.

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 compact and front-loaded with the core concept ('Poker tables the hub deals'), then adds the key distinction between cash and sit-and-go, and ends with the tableId behavior. Every sentence adds information, though the phrasing is slightly informal and the final 'Free.' is terse.

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 4 parameters, 0% schema coverage, no annotations, and no output schema, the description is not complete enough. It explains tableId but leaves limit, state, and format undefined, and does not describe the return shape or whether the tool is read-only. An agent would need to guess at most parameters.

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%, so the description must compensate for the four undocumented parameters. It mentions tableId and explains its meaning ('Name a tableId for one table as everyone sees it'), but it does not explain limit, state, or format. With 0% schema coverage and only one of four parameters addressed, the description is insufficient.

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 names a specific resource ('poker tables the hub deals') and distinguishes two table types (cash tables and sit-and-go tournaments), which is more specific than a bare 'poker tables' name. It does not explicitly contrast with sibling tools like poker_hands or poker_act, so it is clear but not fully differentiated from siblings.

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: it explains what the hub deals and that tableId names one table as everyone sees it. It does not state when to use this tool versus poker_hands, poker_act, poker_open_table, or poker_sit, nor does it give exclusions or alternatives. Usage is implied rather than explicit.

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