What it does
In the author's own words, from each skill's SKILL.md — showing the first 28 of 51 files.
-
kalshi-weather-trader
Trade Kalshi temperature markets, automate Kalshi weather bets, or check NOAA forecasts using the Simmer SDK and DFlow on Solana.
skills/kalshi-weather-trader/ on GitHub (opens in a new tab)SKILL.md -
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/ on GitHub (opens in a new tab)SKILL.md -
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/ on GitHub (opens in a new tab)SKILL.md -
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/ on GitHub (opens in a new tab)SKILL.md -
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…
skills/polymarket-combo-builder/ on GitHub (opens in a new tab)SKILL.md -
polymarket-copytrading
Mirror Polymarket whale wallets, inspect wallet positions, follow specific trader addresses, or paper-trade copytrading with $SIM before using real money. Polling mode is free; Reactor mode is Pro for event-driven real-time mirroring via Simmer's on-chain signal infrastructure.
skills/polymarket-copytrading/ on GitHub (opens in a new tab)SKILL.md -
polymarket-dca-eval-trader
Build and optionally execute a three-tranche Polymarket DCA plan with prop-firm-shaped evaluation envelope checks. Use when the user wants a Bubbles/Roya-style staged averaging template for one thesis, with paper mode by default and explicit live opt-in.
skills/polymarket-dca-eval-trader/ on GitHub (opens in a new tab)SKILL.md -
polymarket-elon-tweets
Trade Polymarket "Elon Musk # tweets" markets, check XTracker pace, monitor tweet-market positions, or configure bucket spreads and entry thresholds. Buys adjacent range buckets when combined cost < $1 for structural edge.
skills/polymarket-elon-tweets/ on GitHub (opens in a new tab)SKILL.md -
polymarket-fast-loop
Trade Polymarket 5-minute and 15-minute crypto sprint markets, automate short-term prediction trading, use CEX momentum or custom signals, or monitor sprint-market positions. Default signal is Binance BTC/USDT klines.
skills/polymarket-fast-loop/ on GitHub (opens in a new tab)SKILL.md -
polymarket-fast-scaler
Trade BTC 5-minute fast markets on Polymarket with a magnitude-gated conviction ladder. Use for BTC 5-minute only; not for ETH/SOL/XRP, 15m windows, raw momentum, or signals below the 0.10% magnitude gate. Reference template; the original performance claim was retracted.
skills/polymarket-fast-scaler/ on GitHub (opens in a new tab)SKILL.md -
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.
skills/polymarket-market-maker/ on GitHub (opens in a new tab)SKILL.md -
polymarket-mert-sniper
Trade near-expiry Polymarket markets, filter by topic, cap bet size, or require strongly skewed odds before entry. Scans final-minute markets 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-mert-sniper/ on GitHub (opens in a new tab)SKILL.md -
polymarket-mil-aircraft-tracker
Track military aircraft cluster signals, trade strike/action Polymarket markets, or check pref.trade-powered skill activity. Fires when tracked military aircraft cluster in a target region.
skills/polymarket-mil-aircraft-tracker/ on GitHub (opens in a new tab)SKILL.md -
polymarket-nothing-ever-happens
Buy NO on standalone non-sports yes/no Polymarket markets priced below a configurable cap. Scans for candidates via Gamma API, filters out sports and grouped markets, checks fees, and executes.
skills/polymarket-nothing-ever-happens/ on GitHub (opens in a new tab)SKILL.md -
polymarket-research
Research any Polymarket topic — get market data, probabilities, volumes, and top holders in one snapshot. Read-only, no trading.
skills/polymarket-research/ on GitHub (opens in a new tab)SKILL.md -
polymarket-signal-sniper
Monitor RSS feeds for news that may move Polymarket markets, configure custom signal sources and keywords, and get article + market pairs with safeguard warnings. Never trades; your agent decides whether and how to trade.
skills/polymarket-signal-sniper/ on GitHub (opens in a new tab)SKILL.md -
polymarket-soccer-shock-ladder
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's server detects shocks in real time and emits pre-sized signals; this skill places the recovery ladder and manages the exit.
skills/polymarket-soccer-shock-ladder/ on GitHub (opens in a new tab)SKILL.md -
polymarket-wallet-xray
X-ray any Polymarket wallet for skill level, entry quality, bot detection, arbitrage research, trader-profile comparison, and edge analysis. Queries Polymarket's public APIs with no authentication; use for research, not blind copytrading, and never assume past returns predict future results.
skills/polymarket-wallet-xray/ on GitHub (opens in a new tab)SKILL.md -
polymarket-weather-trader

skills/prediction-trade-journal/ on GitHub (opens in a new tab)SKILL.md -
simmer-preflight
Pre-trade readiness check for autonomous agents. One call returns wallet identity, venue status, spendable balance, open exposure, and a structured ok_to_trade verdict. Live real-venue trades auto-run this check and refuse when ok_to_trade is False.
skills/preflight/ on GitHub (opens in a new tab)SKILL.md -
simmer-briefing
Daily check-in pattern for Simmer agents. One API call returns portfolio, risk alerts, and opportunities across all venues. Use this in your heartbeat to keep your human informed.
skills/simmer-briefing/ on GitHub (opens in a new tab)SKILL.md -
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. Use after registering an agent on simmer.markets to run pre-built Simmer trading strategies through your MCP-aware agent.
skills/simmer-mcp-setup/ on GitHub (opens in a new tab)SKILL.md -
simmer-skill-builder
Generate complete, installable OpenClaw trading skills from natural language strategy descriptions. Use when your human wants to create a new trading strategy, build a bot, generate a skill, automate a trade idea, turn a tweet into a strategy, or asks "build me a skill that...". Produces a full skill folder (SKILL.md + Python script + config) ready to install and run.
skills/simmer-skill-builder/ on GitHub (opens in a new tab)SKILL.md -
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.
skills/simmer-wallet-setup/ on GitHub (opens in a new tab)SKILL.md -
simmer-x402
Make x402 payments, handle HTTP 402 Payment Required responses, check Base wallet balances, or access Simmer premium endpoints and other paid APIs. Uses USDC on Base.

Review before you install
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.
