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

With no annotations, the description carries the full burden and discloses important behavior: the action is unsigned, requires an Override Disk in the wallet, involves an approve-then-join sequence, seals the table at the sixth seat, and gives the Dragon's seat 95% of the pot. It still lacks failure modes, table-state preconditions, and details about handling the prepared transaction.

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 definition is compact and front-loads the core action before prerequisites and game mechanics. The phrasing 'an approve of the stake' is slightly awkward, and the final sentence adds context that is useful but not essential to invoking the tool.

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 no annotations and no output schema, the description does enough for a two-parameter prepare tool: it explains the action, prerequisite, sequence, and table mechanics. It is not fully complete because it omits edge conditions, failure behavior, and what to do with the returned unsigned preparation.

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 coverage is 100%, so the schema already documents the wallet and table parameters. The description adds that the wallet must contain an Override Disk, but it does not add further meaning to the table id beyond the schema's reference to high_table_state.

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, resource, and context: preparing an unsigned action to take a seat at a Red Dragon high table. It distinguishes this from sibling actions like prepare_red_dragon_flip, prepare_red_dragon_leave, and prepare_red_dragon_refund by focusing on joining a table.

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 says this is used for taking a seat and gives the workflow: approve the stake, then join. It also names the Override Disk prerequisite. However, it does not explicitly state when not to use it or point to alternatives such as high_table_state or prepare_red_dragon_leave if already seated.

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