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

With no annotations provided, the description carries the full burden and does so extensively: it discloses the bare-array response shape, empty-array validity, caching behavior, single logical GET, no auto-fetch of continuation pages, local row/size limits with truncation reporting, and refusal of oversized records without partial fields.

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 a dense paragraph that front-loads purpose and response format but includes vague, partially redundant sentences such as 'Required inputs reflect tool policy...' and 'Other declared filters are forwarded as supplied...' when no filters exist in the schema, adding noise without structural headings.

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 simple one-parameter read tool with no output schema, the description covers the essential return shape, valid empty responses, cache behavior, pagination, and limits. However, it leaves the meaning of 'edition' unexplained and includes irrelevant filter commentary, so it is not fully complete.

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 0%, so the description must compensate. It only repeats that the tool is 'for one edition' and vaguely says 'Required inputs reflect tool policy as well as measured upstream requirements,' without explaining what an edition is, how to obtain it, or any additional meaning beyond the integer schema.

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 action and resource: 'Read the public pack jackpot circulation overview for one edition.' The verb 'Read' and the resource name distinguish it from most sibling tools, though it does not explicitly differentiate it from similar cards_* endpoints like cards_pack_data_wax.

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 implies usage context (requires an edition, read-only overview) and warns that filters are forwarded without guaranteed effectiveness, but it does not provide explicit when-to-use or when-not-to-use guidance compared to alternatives.

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