ranked_draws_status

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

With no annotations, the description carries the full burden and does substantial work: it states this is a single logical GET request, does not auto-fetch continuation pages, limits array responses to 100 rows and 256 KiB, reports truncation, and refuses oversized records. This is far clearer than typical tool descriptions, though authentication and exact return shape are not covered.

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 purpose is front-loaded in the first sentence)Skip. Later statements are mostly informative, but 'Required inputs reflect tool policy as well as measured upstream requirements' is vague, and 'Other declared filters are forwarded as supplied' is boilerplate that does not apply to the single-parameter schema. There is also a missing period after 'GET request'.

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 read endpoint with one optional parameter and no output schema, the description covers the key invocation concerns: username handling, single request behavior, pagination policy, and response limits. It does not describe the shape or semantics of the returned status object, which would be needed to fully use the result without an output schema.

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?

The schema provides only the parameter name and type for username, with no description (0% coverage). The description compensates by explaining that username is optional, forwarded as an explicit account-scoped selector, and that no account is assumed otherwise. For a single optional parameter, this is adequate semantic guidance.

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 uses a specific verb ('Read') and a precise resource ('current and first-unclaimed ranked draw status'), which distinguishes it from sibling draw tools like ranked_draws_available_prizes or ranked_draws_complete. It also clarifies that no account is assumed, adding scope specificity beyond the tool name.

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 explains when the optional username should be supplied and explicitly says no account is assumed, which is useful usage context. However, it does not name alternative tools or state when to prefer this over a sibling such as ranked_draws_complete or frontier_draws_status, leaving the choice to inference.

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