DC rozo-checkout
Use when an agent needs to pay OpenRouter (or any Coinbase invoice) with the crypto it already holds: USDT/USDC on Solana, BNB Chain, Ethereum or Polygon, USDC on Base or Stellar, or BTC over Lightning, with no Coinbase account. A bridge creates a one-time deposit order for that coin, then a funder wallet settles the Coinbase invoice. Triggers on a payments.coinbase.com/payment-links/pl_* (or payment-sessions/paymentSession_*) URL, on "rozo-checkout" / "pay this link with bitcoin", or when a user asks to top up OpenRouter credits with crypto and has no link yet (OpenRouter's crypto credits API returns 410 Gone). Also pays a Bitrefill invoice created with "USDC on Base": triggers on "pay bitrefill", "bitrefill invoice", or an invoice id plus a Base USDC address and amount from Bitrefill. Supports Coinbase payment links and Bitrefill invoices only (not Stripe). Also pays any x402 API (HTTP 402, PAYMENT-REQUIRED) from a prepaid Rozo balance: triggers on "x402", "402 Payment Required", "pay this x402 endpoint"; the payment leg is USDC on Base only (Solana payment leg is coming later).

As a process C 61/100 · Has gaps — weak spots: result and completion, inputs and preconditions, execution cost
How to improve
- Shorten the description to 1024 characters.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- 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.

Against the Agent Skills spec
- error
description-longdescription is 1098 chars, limit 1024 - warning
body-longSKILL.md body ≈ 8860 tokens (recommended < 5000); move details to references/ - note
edit-residuethe text marks something as outdated (lines 622): check that old rules are not kept next to new ones — the full check reads the text for contradictions
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
- 40Execution cost. Instruction body is 8860 tokens: crowds the task out of the window
- 60Tools and files. Uses tools (bash, web, node) that frontmatter does not declare
- 70When it triggers. States when to use, but not when not to
- 100Steps. 24 steps
- 100Failures and branches. 3 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Running it twice. Mutating operations check current state
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 11 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (4 tags): a typed call is more reliable
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.
