AC goldrush-x402
GoldRush x402 — pay-per-request blockchain data access using the x402 protocol (HTTP 402 Payment Required). Use this skill whenever the user is building an AI agent that needs blockchain data without API keys, wants wallet-based micropayments for on-chain data, needs autonomous or no-account access to the GoldRush API, mentions the x402 protocol, or wants no-signup/no-onboarding blockchain data access. This is the right skill for autonomous agents, serverless applications, and prototyping without onboarding. Provides access to 60+ Foundational API endpoints through a transparent reverse proxy with stablecoin payments on Base. If the user needs a traditional API key with monthly billing, use goldrush-foundational-api instead. If the user needs real-time streaming data via WebSocket, use goldrush-streaming-api instead.
As a process C 61/100 · Has gaps — weak spots: inputs and preconditions, failures and branches, progress reporting
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
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 60Tools and files. Uses tools (node) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 100Steps. 4 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 894 tokens
- 100Running it twice. No mutating operations
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.
