Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versiongrimoire-polymarketExecute the skills CLI command in your project's root directory to begin installation:
Fetches grimoire-polymarket from franalgaba/grimoire and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate grimoire-polymarket. Access via /grimoire-polymarket in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

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

polymarketbrew tap Polymarket/polymarket-cli && brew install polymarketPOLYMARKET_OFFICIAL_CLI=/custom/path/polymarketPolymarket 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)Polymarket exposes mid_price for CLOB token midpoint comparisons:
poly_mid = metric("mid_price", polymarket, USDC, "token_id=<clobTokenId>")
Selector keys accepted: token_id, tokenid, market_id, id.
If selector is omitted, the metric falls back to the 3rd argument value.

Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
