Tool DescriptionsA

Average 4.4/5 across 3 of 3 tools scored.

Server CoherenceA
Disambiguation5/5

Each tool has a clear, distinct purpose: creating a payment link, querying payment status, and issuing refunds. There is no overlap or ambiguity.

Naming Consistency5/5

All tool names follow the verb_noun pattern (create_payment_link, query_payment_status, refund_payment), ensuring predictability and ease of use.

Tool Count4/5

With 3 tools, the server is minimal but well-scoped for its targeted purpose of Rwanda payments. It could benefit from additional tools like listing payments, but the current count is reasonable.

Completeness4/5

The tool set covers the essential lifecycle: create, query, refund. Minor gaps like canceling pending payments or listing transactions exist but do not hinder core functionality.

Available Tools

6 tools
cancel_subscriptionA
DestructiveIdempotent
Inspect

Cancel a subscription so it will not renew. Requires the subscription_id, which you get from query_subscription (Flutterwave does not expose it at creation time — the buyer must complete the first payment, then query_subscription returns it).

ParametersJSON Schema
NameRequiredDescriptionDefault
subscription_idYesThe subscription_id returned by query_subscription
Behavior4/5

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds value by explaining the preconditions (needs subscription_id from query_subscription) and the effect (prevents renewal), but does not introduce behavioral contradictions. It reinforces the tool's safety profile without conflicting with annotations.

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?

Two concise sentences cover the tool's purpose, behavior, and usage guidance without any unnecessary words or repetition. Every sentence contributes meaningfully.

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

Completeness5/5

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

For a simple tool with one required parameter and no output schema, the description is complete. It covers the action, prerequisite, source of the parameter, and the effect, making it fully self-contained.

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 100% with a clear description for subscription_id. The description repeats this but adds critical context about where the ID comes from and why it's needed, enhancing understanding beyond the schema alone.

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 clearly states the action ('Cancel a subscription') and the result ('so it will not renew'). It effectively distinguishes from siblings like query_subscription by indicating that this tool is for cancellation, not querying.

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

Usage Guidelines5/5

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

The description provides explicit context for when to use the tool (to cancel a subscription) and includes a crucial prerequisite: the subscription_id must be obtained from query_subscription after the first payment. It also explains why the ID is not available at creation time, preventing misuse.

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

query_payment_statusA
Read-only
Inspect

Check whether a Rwanda payment (created by create_payment_link) has been paid. Queries Flutterwave directly — pull-based, no webhook needed. paid=true when status is PAID.

ParametersJSON Schema
NameRequiredDescriptionDefault
tx_refYesThe tx_ref returned by create_payment_link
Behavior4/5

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

Annotations already provide readOnlyHint=true (read operation) and openWorldHint=true (dynamic responses). The description adds specific behavioral details: queries Flutterwave directly, pull-based model, and the condition for paid=true. No contradictions.

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?

Two concise sentences that front-load the key purpose and behavior. Every word contributes value; no fluff.

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?

No output schema, but the description explains the meaning of paid=true. It covers the core use case. Could mention possible other statuses, but for a simple status check it's sufficient.

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?

Schema coverage is 100% (one parameter tx_ref described as returned by create_payment_link). The description reiterates that tx_ref comes from that function, adding slight value but not deeply elaborating on format or constraints. Baseline 3 is appropriate.

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 clearly states the tool's purpose: checking if a Rwanda payment created by create_payment_link has been paid. It specifies pull-based querying (no webhook) and the condition for paid=true when status=PAID. This distinguishes it from siblings like create_payment_link and refund_payment.

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

Usage Guidelines4/5

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

The description indicates when to use this tool (after creating a payment link, for pull-based status checks) and that it is not webhook-dependent. It could be more explicit about when not to use (e.g., for non-Rwanda payments) but provides clear context.

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

query_subscriptionA
Read-only
Inspect

Check a subscription created by create_subscription_link. Query by customer_email (required); pass plan_id (returned at creation) to disambiguate when the same email has several plans. active=true when the subscription status is ACTIVE; NOT_SUBSCRIBED_YET means the buyer has not completed the first payment yet. The result includes subscription_id — keep it to cancel later.

ParametersJSON Schema
NameRequiredDescriptionDefault
plan_idNoOptional plan_id returned by create_subscription_link (disambiguates multiple subscriptions on the same email).
customer_emailYesThe buyer email used in create_subscription_link
Behavior5/5

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

Beyond annotations (readOnlyHint, openWorldHint), the description adds meaningful context: explains the status values (active=true, NOT_SUBSCRIBED_YET) and that the result includes subscription_id for later cancellation.

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?

Three sentences, each serving a clear purpose: stating overall function, parameter guidance, and output interpretation. No unnecessary words.

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 no output schema, the description adequately explains key return values (status, subscription_id). Could be slightly more comprehensive about other possible fields, but sufficient for the main use case.

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 100%, so parameters are already documented. The description reinforces that customer_email is required and plan_id is optional, adding the helpful context that plan_id is returned at creation time.

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 clearly states it checks a subscription created by create_subscription_link, specifies required and optional parameters, and explains the status output. It distinguishes itself from sibling tools like cancel_subscription and query_payment_status.

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

Usage Guidelines4/5

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

It outlines when to use the tool (for checking a subscription) and when to use plan_id (disambiguation). It doesn't explicitly state when not to use it, but the sibling context makes it clear this is for status checking only.

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

refund_paymentA
Destructive
Inspect

Refund a paid payment (created by create_payment_link). Full refund by default; pass amount for a partial refund where supported. Refunds respect the same owner policy guardrails (x-agentpay-max-amount) as payments — the amount is checked before anything is sent to the gateway.

ParametersJSON Schema
NameRequiredDescriptionDefault
amountNoOptional partial-refund amount in the local currency major unit. Omit for a full refund.
tx_refYesThe tx_ref of the paid payment (same id used by query_payment_status)
Behavior5/5

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

Adds valuable behavioral context beyond annotations: full refund by default, partial refund via amount parameter, and guardrail checks before gateway call. Annotations already indicate destructiveHint=true, but description enriches understanding.

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?

Two concise sentences, front-loaded with main purpose. No fluff, every sentence earns its place.

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

Completeness5/5

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

For a tool with no output schema, description covers prerequisites, behavioral traits, parameter usage, and guardrails. Sufficient for agent to invoke correctly.

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 description coverage is 100%, but description adds meaning: clarifies amount as 'partial refund where supported', and ties tx_ref to query_payment_status usage. Adds value beyond 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 clearly states 'Refund a paid payment' with specific verb and resource. It also specifies the source (create_payment_link) and differentiates from siblings (create_payment_link, query_payment_status) by focusing on refund operation.

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

Usage Guidelines4/5

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

Provides context: only for payments created by create_payment_link, and mentions policy guardrails. Lacks explicit when-not-to-use or alternatives, but context is clear enough.

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