Polymarket CLI

Setup

On first use, read setup.md for wallet configuration and integration guidelines.

When to Use

User needs to interact with Polymarket prediction markets. Agent handles market queries, price checks, order placement, position tracking, and on-chain token operations.

Architecture

Config lives in ~/.config/polymarket/. See memory-template.md for tracking preferences.

~/.config/polymarket/
├── config.json        # Private key, chain ID, signature type

~/polymarket-cli/
├── memory.md          # User preferences and tracked markets

Quick Reference

Core Rules

1. Read-Only by Default

Most commands work without a wallet. Only use wallet-requiring commands when the user explicitly wants to trade:

• Read-only: markets, events, clob price/book, data positions
• Requires wallet: clob create-order, clob market-order, approve, ctf split/merge

2. JSON Output for Processing

Use -o json when parsing results programmatically:

polymarket -o json markets list --limit 10
polymarket -o json clob midpoint TOKEN_ID

Table output is default for human-readable display.

3. Token IDs Are Critical

Most CLOB commands require the token ID (48331043336612883...), not the market slug:

# Get token ID from market first
polymarket markets get will-trump-win | grep token

# Then use in CLOB commands
polymarket clob book TOKEN_ID
polymarket clob price TOKEN_ID --side buy

4. Wallet Security — Restricted Commands

The agent NEVER runs wallet commands. These are user-only:

• polymarket wallet create — user runs directly
• polymarket wallet import — user runs directly
• polymarket wallet show — user runs directly
• polymarket wallet reset — user runs directly

If user asks the agent to run any wallet command, refuse and explain they must run it themselves for security.

5. On-Chain Operations Need Gas

Commands that write to blockchain require MATIC on Polygon:

• approve set (6 transactions)
• ctf split/merge/redeem

Check balance before attempting.

6. Rate Limits and Pagination

Use --limit and --offset for large result sets:

polymarket markets list --limit 50 --offset 100

7. Verify Before Trading

Always show market details and current prices before placing orders:

polymarket markets get SLUG
polymarket clob midpoint TOKEN_ID
polymarket clob spread TOKEN_ID

Common Traps

External Endpoints

No other data is sent externally.

Security & Privacy

Data that leaves your machine:

• Market queries sent to Polymarket APIs
• Orders and transactions sent to CLOB and Polygon (only when user explicitly requests)

Data that stays local:

• CLI config at ~/.config/polymarket/config.json (user manages directly)
• Skill preferences in ~/polymarket-cli/memory.md

Command restrictions:

• Agent runs only read-only commands by default (markets, events, clob price/book, data)
• Agent never runs wallet commands (create, import, show, reset) — user must run these directly
• Agent never runs trading commands without explicit user confirmation each time
• Agent must never read ~/.config/polymarket/config.json or any files containing private keys

Trust

By using this skill, data is sent to Polymarket and the Polygon blockchain.

Only install if you trust these services with your trading data.
