Vincent - Polymarket for agents

# Vincent - Polymarket for agents

Use this skill to create a Polymarket wallet for your agent and trade on prediction markets. Browse markets, place bets, track holdings, and manage orders — all without exposing private keys to the agent. Wallets use Gnosis Safe on Polygon with gasless trading through Polymarket's relayer.

**The agent never sees the private key.** All operations are executed server-side. The agent receives a scoped API key that can only perform actions permitted by the wallet owner's policies. The private key never leaves the Vincent server.

All commands use the `@vincentai/cli` package. API keys are stored and resolved automatically — you never handle raw keys or file paths.

## Security Model

This skill is designed for **autonomous agent trading with human oversight via server-side controls**. Understanding this model is important:

**No environment variables are required** because this skill uses agent-first onboarding: the agent creates its own Polymarket wallet at runtime by calling the Vincent API, which returns a scoped API key. There is no pre-existing credential to configure. The CLI stores the returned API key automatically during wallet creation. The config paths where the key is persisted (`${OPENCLAW_STATE_DIR:-$HOME/.openclaw}/credentials/agentwallet/` or `./agentwallet/`) are declared in this skill's metadata.

**The agent's API key is not a private key.** It is a scoped Bearer token that can only execute actions within the policies set by the wallet owner. The Vincent server enforces all policies server-side — the agent cannot bypass them regardless of what it sends. If a trade violates a policy, the server rejects it. If a trade requires approval, the server holds it and notifies the wallet owner via Telegram for out-of-band human approval.

**Model invocation is intentionally enabled.** The purpose of this skill is to give AI agents autonomous Polymarket trading capabilities. The agent is expected to invoke trading actions (bro...
