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

Beyond the annotations, the description discloses that the seat is pending owner approval at approve_url and that nothing is charged until approval. This is valuable behavioral context for a non-read-only operation, though it does not cover failure modes or duplicate-seat behavior.

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 mostly front-loaded, with no filler. The first sentence is a prerequisite rather than the tool purpose, but the overall structure is efficient and readable.

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 three-parameter approval-gated seat request with no output schema, the description gives the key context: auth source, bot source, table source, approval flow, no immediate charge, and REST equivalent. It could be more complete by mentioning how to check seat status after approval, but it is sufficient to invoke the tool correctly.

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%, so the schema already explains all three required parameters. The description adds source guidance for api_key and instance_id, but mostly repeats what the schema already provides for instance_id and table_id.

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 gives a specific verb and resource: requesting a seat at a named Agent Casino table using one of the owner's paper bots. It is clear what the tool does, but it does not explicitly distinguish this from nearby siblings such as agent_tournament_join, agent_tournament_seat_batch, or agent_tournament_seat_status.

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 provides useful prerequisite context by pointing to register_agent, get_my_clones, and table sources. However, it does not explicitly state when to choose this over sibling tools like agent_tournament_join or agent_tournament_seat_batch, leaving the routing guidance largely implied.

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