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

Annotations already declare read-only, idempotent, and non-destructive behavior; the description adds useful runtime details: raw Cakto data with count/next/previous/results pagination, the flattened action note, and bulk execution support. There is no contradiction with the 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 overall purpose, then uses scannable action and filter lists. The '[Flattened action: list]' note is useful but makes the structure slightly fragmented.

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?

The tool has 12 optional parameters, no parameter descriptions, and no output schema, so the description carries substantial weight. It covers filters, date formats, pagination, and bulk behavior, but the account parameter is unexplained and the get-action return shape is not described.

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?

With 0% schema description coverage, the description compensates by explaining most parameters: status as CSV, type as unique|subscription, offer_type as main|upsell|downsell|orderbump, paid_at_gte/paid_at_lt as YYYY-MM-DD, page, and order_ids for bulk. It omits the account parameter, which appears in the input schema, so the coverage is not complete.

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 clearly identifies the tool as reading Cakto orders and enumerates two actions: list (with a rich set of filters) and get (single order by order_id). It is specific about the verb and resource, but it does not explicitly distinguish the get action from the sibling tool cakto_orders_get.

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 gives practical context for the list action with filter formats and for the get action by requiring order_id, plus bulk support via order_ids. However, it does not provide explicit when-to-use versus when-not-to-use guidance relative to sibling tools like cakto_orders_get.

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