Grimoire Polymarket Skill

Use this skill for Polymarket market discovery, CLOB market data, and order-management operations through the polymarket venue adapter.

Preferred invocations:

• grimoire venue polymarket ...
• npx -y @grimoirelabs/cli venue polymarket ... (no-install)
• bun run packages/cli/src/index.ts venue polymarket ... (repo-local)
• grimoire-polymarket ... (direct binary from @grimoirelabs/venues)

Recommended preflight:

• grimoire venue doctor --adapter polymarket --json
• grimoire venue polymarket info --format json

Commands

Canonical agent commands:

• grimoire venue polymarket info [--format <auto|json|table>]
• grimoire venue polymarket search-markets [--query <text>] [--slug <slug|url>] [--question <text>] [--event <text>] [--tag <text>] [--category <text>] [--league <text>] [--sport <text>] [--open-only <true|false>] [--active-only <true|false>] [--ignore-end-date <true|false>] [--tradable-only <true|false>] [--all-pages <true|false>] [--max-pages <n>] [--stop-after-empty-pages <n>] [--limit <n>] [--format <auto|json|table>]

Allowed passthrough groups (official CLI surface, restricted by wrapper policy):

• markets (list|get|search|tags)
• events (list|get|tags)
• tags (list|get|related|related-tags)
• series (list|get)
• sports (list|market-types|teams)
• clob (book/prices/markets/orders/trades/etc.)

Blocked groups in this wrapper (intentionally not exposed for agents):

• wallet
• bridge
• approve
• ctf
• setup
• upgrade
• shell

Legacy compatibility aliases are still supported (market, book, midpoint, spread, price, last-trade-price, tick-size, neg-risk, fee-rate, price-history, order, trades, , , , ) but should not be used for new agent flows.

Runtime Configuration

Adapter/runtime auth (for spell execution and authenticated CLOB operations):

• required: POLYMARKET_PRIVATE_KEY
• optional API creds: POLYMARKET_API_KEY, POLYMARKET_API_SECRET, POLYMARKET_API_PASSPHRASE
• optional derive toggle (default true): POLYMARKET_DERIVE_API_KEY=true|false
• optional signature routing: POLYMARKET_SIGNATURE_TYPE (0 EOA, 1 POLY_PROXY, 2 GNOSIS_SAFE), POLYMARKET_FUNDER

Venue CLI backend:

• Official binary required: polymarket
• Install: brew tap Polymarket/polymarket-cli && brew install polymarket
• Optional path override: POLYMARKET_OFFICIAL_CLI=/custom/path/polymarket

Spell Actions

Polymarket uses custom action type with op: "order" for order placement:

polymarket.custom(
  op="order",
  token_id="TOKEN_ID",
  price="0.55",
  size="100",
  side="BUY",
  order_type="GTC",
)

The adapter does not support runtime constraints (max_slippage, etc.). Order routing:

• GTC/GTD → limit order (createAndPostOrder)
• FOK/FAK → market order (createAndPostMarketOrder)

Adapter Notes

• Adapter name: polymarket
• Execution type: offchain
• Supported chain metadata: 137 (Polygon)
• Action type: custom
• Supported custom ops: order, cancel_order, cancel_orders, cancel_all, heartbeat

Order argument aliases accepted:

• token: token_id or tokenID or tokenId or coin
• amount: size or amount
• side: BUY/SELL
• order type: GTC/GTD/FOK/FAK

Order type routing:

• GTC/GTD -> limit order path (createAndPostOrder)
• FOK/FAK -> market order path (createAndPostMarketOrder)

Notes

• Prefer --format json for agent and automation workflows.
• search-markets is the agent-oriented normalized discovery command; passthrough markets search is thinner and closer to official behavior.
• Keep prompts/tooling on this CLI surface; do not call Polymarket HTTP APIs directly from advisory tools.
