  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Metered API Marketplace

Provide a production-lean template for: OpenClaw Skill → Public API Endpoint → Usage Metering → Crypto Payment Gateway → BTC/ETH wallets. This skill ships a runnable reference server (Fastify + SQLite) that: Accepts structured JSON input Performs a high-value transformation (pluggable “transformers”) Returns structured JSON output Enforces signed API key auth Checks prepaid balance, deducts per call, and logs usage Accepts payment webhooks (Coinbase Commerce / BTCPay Server style) Applies a 2.5% platform fee in the ledger (fee addresses configurable)

1) Pick the productized capability (the thing people pay for)

Choose ONE transformer that is: high leverage (makes/keeps money) repeatable (called often) defensible (data, heuristics, workflow, or automation — not “generic summarization”) Good defaults: revenue/offer optimizer ad copy optimizer lead scoring contract risk flags If unclear, start with the included revenue-amplifier transformer and replace it later.

2) Run the reference server locally

Use the bundled server in scripts/server/. Typical run: cd scripts/server npm install cp .env.example .env and edit npm run dev Set flat launch pricing in .env: COST_CENTS_PER_CALL=25 # $0.25/call

3) Create an API key

Use scripts/server/admin/create_key_pg.js (or the admin HTTP endpoint) to create a key and starting balance.

4) Integrate from an OpenClaw skill / agent

Call the public endpoint with: x-api-key x-timestamp (unix ms) x-signature = hex(HMAC_SHA256(api_secret, ${timestamp}.${rawBody}))

5) Add real payments

Wire a payment processor webhook to /v1/payments/webhook/:provider. Providers are adapter-based: start with “manual” credits (admin script) then add Coinbase Commerce or BTCPay Server

6) Ship

Deploy behind TLS (Cloudflare / Fly.io / Render / AWS / GCP). Put rate limiting at the edge + in-app.

scripts/server/

Runnable reference implementation: Fastify API server (long-running) Postgres ledger (balances, usage, credits) Signed API key auth Rate limiting + basic anti-abuse Webhook endpoint(s)

scripts/nextjs-starter/

Vercel-ready Next.js API implementation: Serverless API routes (no listen()) Postgres ledger (Supabase Transaction Pooler recommended) Same auth + pricing + webhook concepts

references/

Read only when needed: references/api_reference.md – endpoint contracts + auth/signing references/billing_ledger.md – pricing, fee logic, idempotency references/providers.md – provider adapters (Coinbase/BTCPay patterns)

Category context

Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
