taxsort_mint_coupon

Create a new operator-owned discount coupon.

The coupon owns its binding: tool_ids names the tools it discounts, and re-pricing a tool never touches it. A coupon bound to no tool discounts nothing, however many patrons redeem it.

Input Schema

TableJSON Schema

Name	Required	Description
`name`	Yes	The catchy code patrons type to redeem (operator-scoped uniqueness).
`tool_ids`	No	The tools this coupon discounts — tool ids or MCP tool names, or ``["*"]`` for every tool priced above zero.
`dpop_token`	No
`total_uses`	No	Aggregate cap across all patrons (default None = unlimited).
`valid_from`	Yes	ISO-8601 datetime when the coupon becomes active.
`valid_until`	Yes	ISO-8601 datetime when the coupon expires.
`uses_per_patron`	No	How many tool calls one patron can claim the discount on (default 1; pass null/None for unlimited within the window).
`discount_percent`	Yes	Percentage off the base price (0-100).

B3.3/5.0

Behavior3/5

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

With no annotations the description carries the full behavioral burden, and it does disclose one genuinely non-obvious trait: a coupon bound to no tool is a silent no-op regardless of redemptions, and re-pricing a tool does not affect its binding. It omits other material behavior for a mutation tool with 8 params — required operator credentials/permissions, whether minting is idempotent, and what happens on a name collision.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The verb and resource are front-loaded in the first sentence, and the second paragraph is short. The phrasing ('however many patrons redeem it') is slightly indirect, but every sentence contributes meaning rather than filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, and the schema carries most parameter detail. For a no-annotation mutation tool with 8 parameters, though, the description leaves auth/permission requirements and failure modes unaddressed, so it is adequate but incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 88%, so a baseline of 3 applies; the description earns above that by adding semantics the schema only hints at — that tool_ids constitutes the coupon's owned binding and that the null default means the coupon discounts nothing. It adds nothing for the remaining parameters (dpop_token, total_uses, uses_per_patron, dates, discount_percent).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence states a specific verb and resource: 'Create a new operator-owned discount coupon.' 'New' implicitly separates it from update_coupon, but the description never names or contrasts with any of the many coupon siblings (update_coupon, delete_coupon, list_coupons, redeem_coupon).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no routing to alternatives such as redeem_coupon or update_coupon. The second paragraph explains binding mechanics rather than when an agent should mint a coupon versus taking another action.

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