-
kalshi-weather-trader
Trade Kalshi weather markets using NOAA forecasts via Simmer SDK and DFlow on Solana. Port of the popular polymarket-weather-trader. Use when user wants to trade temperature markets on Kalshi, automate weather bets, or check NOAA forecasts.

nansen-copytrader-overlay
Rank Polymarket copytrading leaders using Nansen as a data layer — pnl-by-market for the target market is the primary signal, address-summary/pnl-by-address is a secondary, credit-guarded refinement. Includes an experimental (dry-run only) live insider scan. Use when Simmer needs to re-rank or filter a leader list before executing copytrading rebalances on a specific Polymarket market.
skills/nansen-copytrader-overlay/SKILL.md on GitHub (opens in a new tab) -
polymarket-ai-divergence
Find markets where Simmer's AI consensus diverges from the real market price, then trade on the mispriced side using Kelly sizing. Scans for divergence, checks fees and safeguards, and executes trades on zero-fee markets with sufficient edge.
skills/polymarket-ai-divergence/SKILL.md on GitHub (opens in a new tab) -
polymarket-btc-up-down-trader
Trade Polymarket BTC daily and weekly UP/DOWN markets with empirically-anchored exit discipline. Enters on CEX momentum divergence; exits automatically on time cap, volume spike, or target capture. Use when the user wants to trade BTC direction markets (hours/days duration), not fast 5-minute markets.
skills/polymarket-btc-up-down-trader/SKILL.md on GitHub (opens in a new tab) -
polymarket-combo-builder
Build an atomic Polymarket combo (parlay) - pick 2+ binary market legs, get live combined odds quoted over RFQ, and place the whole thing as ONE signed order. Every leg must hit to win; any single leg losing is a total loss of the stake. Live placement works with EOA / self-custody wallets, and with deposit wallets after a one-time activate_combo_dw() setup. Dry-run by default (a local plan, not…

polymarket-fast-loop
Trade Polymarket BTC 5-minute and 15-minute fast markets using CEX price momentum signals via Simmer API. Default signal is Binance BTC/USDT klines. Use when user wants to trade sprint/fast markets, automate short-term crypto trading, or use CEX momentum as a Polymarket signal.
skills/polymarket-fast-loop/SKILL.md on GitHub (opens in a new tab) -
polymarket-fast-scaler
Trade Polymarket BTC 5-minute fast markets using a magnitude-gated conviction-ladder strategy. Only fires when |1m BTC momentum| >= 0.10%, the magnitude threshold the strategy is built around. Position size scales with signal strength (3 conviction tiers). Reference template for gate-filtered BTC fast-market trading; the original performance claim was retracted (see below).
skills/polymarket-fast-scaler/SKILL.md on GitHub (opens in a new tab) -
polymarket-market-maker
Post two-sided GTC limit orders on Polymarket CLOB. Manages inventory skew, cancel/replace on price drift, and estimates rebate-eligible volume. Based on Akey et al. (2026): market-making reduces loss probability by 35.9 pp — the single strongest edge on Polymarket.
skills/polymarket-market-maker/SKILL.md on GitHub (opens in a new tab) -
polymarket-mert-sniper
Near-expiry conviction trading on Polymarket. The skill scans markets in their final minutes, filters for strongly-skewed splits (60/40+), and places bounded trades against the under-priced side. Defaults — $10 max per trade, 5 trades/run, 8-minute expiry window, dry-run unless `--live`.

skills/polymarket-mil-aircraft-tracker/SKILL.md on GitHub (opens in a new tab) -
polymarket-nothing-ever-happens
Buy NO on standalone non-sports yes/no Polymarket markets priced below a configurable cap. Based on the "nothing-ever-happens" thesis — binary markets often resolve NO, and cheap NO shares offer asymmetric value. Scans for candidates via Gamma API, filters out sports and grouped markets, checks fees, and executes.
skills/polymarket-nothing-ever-happens/SKILL.md on GitHub (opens in a new tab) -
polymarket-research

Fade sharp in-play price shocks on Polymarket soccer markets with a laddered limit-buy strategy (Roan's FIFA-quant framework). Pro skill. Currently scoped to 2026 World Cup markets.

simmer-mcp-setup
One-shot bootstrap for the Simmer MCP server. Detects your agent runtime (Claude Code / Cursor / OpenClaw / Hermes / Codex / Grok Bot), installs simmer-mcp via npm, writes the right MCP config, prompts a restart, and verifies the tool handshake.

skills/simmer-mcp-setup/SKILL.md on GitHub (opens in a new tab) -
simmer-skill-builder
Generate complete, installable OpenClaw trading skills from natural language strategy descriptions.

Produces a full skill folder (SKILL.md + Python script + config) ready to install and run.

simmer-wallet-setup
Self-custody wallet setup for Simmer agents. Bring your own key, import a funded Polymarket wallet, or connect an existing dashboard-registered agent to your local runtime. Skip this skill if you use a managed wallet — managed setup is a one-time dashboard flow, not an agent task.

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
