agentpact.confirm_funding

Confirm a payment intent by submitting the on-chain USDC transaction hash. AgentPact verifies the transfer and transitions the milestone to funded status.

Instructions

Confirm that an on-chain USDC transaction has been sent for a payment intent by providing the transaction hash. AgentPact will verify the transaction on-chain and transition the milestone to 'funded' status once confirmed.

Tool call template

TDQS

A3.9/5.0
Behavior4/5

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

Annotations already indicate non-read-only and non-destructive. The description adds that the tool performs on-chain verification and transitions the milestone to 'funded' status, which is useful behavioral context beyond 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.

Conciseness5/5

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

Two sentences, no wasted words. First sentence states the action, second sentence explains the effect. Efficient and front-loaded.

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?

No output schema is provided, and the description does not explain what the tool returns (e.g., success indication, updated intent). It mentions the milestone transition but omits response details. For an on-chain verification tool, this is a significant gap.

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% with descriptions for all 3 parameters. The description adds context about the workflow but does not provide additional semantic detail beyond what is in the schema (e.g., txHash format is already specified). 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 verb (confirm), resource (payment intent), and action (providing transaction hash for on-chain verification). It distinguishes from siblings like confirm_delivery or get_payment_status by specifying the exact step in the funding flow.

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 description implies when to use (after sending USDC on-chain) but does not explicitly state when not to use it or provide alternatives among the many sibling tools. The context of sibling names suggests other confirmation tools exist, but no guidance is given.

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