A3.8/5.0
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the destructive nature is covered. The description adds the 'unpaid' precondition, which is useful, but it does not disclose irreversibility, downstream effects, or required permissions beyond what annotations imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. It conveys the essential action and condition efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with one parameter, strong schema coverage, and destructive annotations, the description is nearly complete. It clearly states the action and condition, though it could improve by explicitly routing paid invoices to a sibling like refundInvoice.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% coverage for the single parameter invoice_id, so the description does not need to explain it. The 'unpaid' qualifier adds context but does not add parameter-specific semantic detail beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Delete'), a clear resource ('invoice'), and a meaningful scope qualifier ('unpaid'). This distinguishes it from siblings like refundInvoice, which would apply to paid invoices.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'unpaid' qualifier implies when the tool should be used, and the sibling list suggests a contrast with refundInvoice. However, the description does not explicitly state when not to use it or name an alternative for paid invoices.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.5/5.0
Disambiguation5/5
Each tool maps to a distinct resource or action: invoices, subscription plans, subscriptions, checks, transfers, balance, rates, and auth flows. The two-step connect/connect_status pair is clearly separated into initiate and poll, and similar actions like archiveSubscriptionPlan versus cancelSubscription are explicitly differentiated.
Naming Consistency4/5
The vast majority of tools follow a camelCase verb_noun pattern such as createInvoice, getSubscriptions, and refundInvoice. The exceptions are connect_status and get_docs, which use snake_case, creating a minor but noticeable inconsistency.
Tool Count4/5
At 21 tools, the server is on the heavier side but the breadth of a merchant payment API justifies it: auth, invoices, subscriptions, transfers/checks, balances, exchange rates, stats, webhooks, and docs all need coverage. No tools feel redundant, though a few list-only endpoints could arguably be consolidated.
Completeness3/5
Core invoice and subscription lifecycles are well covered: create, list, delete, archive, cancel, and refund. However, there is no visible createTransfer or createCheck tool even though the API includes transfers/checks docs and deleteCheck/getTransfers, leaving a notable dead end for initiating transfers.
