Simmer Skill Builder

Generate complete, runnable Simmer trading skills from a strategy description.

> You are building an OpenClaw skill that trades prediction markets through the Simmer SDK. The skill you generate will be installed into your skill library and run by you — it must be a complete, self-contained folder that works out of the box.

Workflow

Step 1: Understand the Strategy

Ask your human what their strategy does. They might:

Describe a trading thesis in plain language

Paste a tweet or thread about a strategy

Reference an external data source (Synth, NOAA, Binance, RSS, etc.)

Say something like "build me a bot that buys weather markets" or "create a skill for crypto momentum"

Clarify until you understand: 1. Signal — What data drives the decision? (external API, market price, on-chain data, timing, etc.) 2. Entry logic — When to buy? (price threshold, signal divergence, timing window, etc.) 3. Exit logic — When to sell? (take profit threshold, time-based, signal reversal, or rely on auto-risk monitors) 4. Market selection — Which markets? (by tag, keyword, category, or discovery logic) 5. Position sizing — Fixed amount or smart sizing? What default max per trade?

Step 2: Load References

Read these files to understand the patterns:

1. references/skill-template.md — The canonical skill skeleton. Copy the boilerplate blocks verbatim (config system, get_client, safeguards, execute_trade, CLI args). 2. references/simmer-api.md — Simmer SDK API surface. All available methods, field names, return types.

If the Simmer MCP server is available (simmer://docs/skill-reference resource), prefer reading that for the most up-to-date API docs. Otherwise use references/simmer-api.md.

For real examples of working skills, read:

references/example-weather-trader.md — Pattern: external API signal + Simmer SDK trading

references/example-mert-sniper.md — Pattern: Simmer API only, filter-and-trade

Step 3: Get External API Docs (If Needed)

If the strategy uses an external data source:

Polymarket CLOB data: If the Polymarket MCP server is available, search it for relevant endpoints (orderbook, prices, spreads). If not available, the key public endpoints are:

- GET https://clob.polymarket.com/book?token_id= — orderbook - GET https://clob.polymarket.com/midpoint?token_id= — midpoint price - GET https://clob.polymarket.com/prices-history?market=&interval=1w&fidelity=60 — price history - Get polymarket_token_id from the Simmer market response.

Other APIs (Synth, NOAA, Binance, RSS, etc.): Ask your human to provide the relevant API docs, or web-fetch them if you have access.

Step 4: Generate the Skill

Create a complete folder on disk:

├── clawhub.json      # ClawHub + automaton config
