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

Annotations already declare readOnlyHint=true / destructiveHint=false, and the description reinforces rather than contradicts that ('Nothing is bought or sold in this chat'). Beyond that it discloses pagination size, the full shape of returned data, and a real-money warning on the sibling refund path, which is meaningful behavioral context the annotations do not cover.

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?

Dense and largely waste-free, but the store-administration preamble delays the operative verb to the second sentence. That framing does disambiguate scope, so it earns much of its length, though the action could be front-loaded.

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?

No output schema exists, and the description compensates by enumerating every returned field (`id`, `status` with its enum values, `paidAt`, buyer info, items/order bump, totals, discounts, `refundable`) plus the aggregate `last30Days` metrics. Nothing an agent needs in order to call or interpret the result is missing.

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% and both parameters are documented in the schema, so the baseline is 3. The description adds only a page-size hint ('50 per page') and the nextPage handoff pattern, without covering the workspaceId defaulting behavior, so it stays at baseline.

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?

States a specific verb and resource ('List paid store orders, newest first, 50 per page') and frames it in the domain ('the business's own link-in-bio store in Ignix'). An agent can immediately tell this apart from refund_store_order or the store-product tools without inspecting any schema.

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?

Gives explicit continuation rules ('When `hasMore` is true, call again with `nextPage`') and names the follow-up alternative with its precondition ('A refundable order can be refunded with refund_store_order, which moves real money: confirm with the user first'). Conditions for use and for escalation are both spelled out.

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