Payment Processing
Governed payment operations for AI agents — intent-based payments with approval gates, evidence collection, reconciliation, and full audit trails. Agents propose, policy decides, humans approve, system executes.
What this skill teaches
A reusable playbook for a specific kind of work.
An MCP server tells an agent which actions are available. A skill adds the judgment around those actions: how to recognize the job, which sequence to follow, what to avoid, and how to decide that the result is complete.
Orchestrate governed payment operations — create payment intents, manage approval gates, execute approved payments, reconcile against invoices, and maintain audit evidence. Use when processing payments, issuing refunds, creating payouts, checking payment status, reconciling transactions, or generating payment reports.…
Architecture
How Payment Processing guides an ADK-Rust agent.
The skill stays readable and portable because it contains instructions rather than service credentials or business data. ADK-Rust supplies it to the agent, the agent chooses from its reviewed tool boundary, and the connected MCP server performs the authenticated operation.
01
User request
The agent receives a goal expressed in ordinary language.
02
Payment Processing skill
Matches intent, supplies the decision guide, and narrows the tool boundary.
03
ADK-Rust agent
Plans the workflow and streams each meaningful step through the runtime.
04
mcp-payments
Executes authenticated operations against the system that owns the capability.
05
Verified result
The skill's completion rules shape the evidence returned to the user.
Decision guide
How the agent turns a request into the right action.
These routes come directly from the skill instructions. They help the model recognize intent and select a focused tool or workflow instead of improvising across the entire capability surface.
"refund", "return", "credit back"?
WORKFLOW 2: Refund
"payout", "pay vendor", "transfer out"?
WORKFLOW 3: Payout
"status", "where's my payment", "check payment"?
WORKFLOW 4: Payment Status
"reconcile", "match", "verify payment"?
WORKFLOW 5: Reconciliation
Unclear?
Ask: "Would you like to collect a payment, issue a refund, or check a payment status?"
Proven workflows
Repeatable sequences for useful outcomes.
A workflow joins several tool calls into a task the user actually recognizes. The skill explains the sequence and the intended result while ADK-Rust streams the agent's progress through the shared runtime.
013-4 calls
Checkout (collect money)
Intent + evidence + approval gate
024-5 calls
Refund
Verify original + intent + evidence + approval
033 calls
Payout (pay vendor)
Intent + evidence + mandatory approval
041 calls
Status Check
Current state with reconciliation info
052-3 calls
Reconciliation
Match payments to invoices/orders
Tool boundary
The skill may use 10 documented tools.
This allowlist is declared by the skill. It keeps the agent focused on the actions needed for this job while mcp-payments retains responsibility for authentication, validation, and the connected system.

Working rules
What the agent should do.
- Follow the decision guide, use the declared tool boundary, and verify the result before responding.
Operating boundaries
What the agent should avoid.
- Review the complete SKILL.md before enabling this skill for production work.
Install and connect
Add the skill beside the capability it expects.
Install the repository where your ADK-Rust skill loader can discover it, connect mcp-payments, and confirm the declared tools are available before asking the agent to use the workflow.
