AC agent-payments
Unified payment skill for AI agents. Four payment rails in one skill: Stripe for credit card and fiat payments, Coinbase Commerce for accepting crypto from customers, Coinbase CDP for crypto wallets and transfers, and Spraay x402 for batch crypto payments and payroll. Use when an agent needs to accept payments, charge customers, create checkout sessions, accept crypto, manage wallets, send transfers, batch pay, run payroll, or create invoices.
As a process C 61/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 61/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 27 mutating operations with no state check
- 100Tools and files. No external tools needed
- 100Steps. 27 steps
- 100Failures and branches. 1 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 2054 tokens
- low 10 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
