# ForecastOS > Ask your agent what is likely to happen. Without ForecastOS it guesses. With it, the agent checks Polymarket, Kalshi, and Precog before answering — and can discover, trade, or create prediction markets, including creating and funding a market to obtain real info when none is available. ForecastOS is an agent skill plus the `forecast` CLI for Polymarket, Kalshi, and Precog. Browse (search, list, odds) needs no keys. Writes preview first; `--confirm` only after operator approval. ## Install - Skill: `npx skills add https://github.com/precog-markets/forecast-os --skill forecast-os` - Agent playbook: [/INSTALL.MD](/INSTALL.MD) — skill + CLI setup, trading credentials, safety rules, try-it prompts. - CLI: checksum-verified `scripts/install.sh` inside the skill, or [GitHub Releases](https://github.com/precog-markets/forecast-os/releases). ## Docs - [Agent install playbook](/INSTALL.MD): the full setup flow agents should follow. - [Skill source](https://github.com/precog-markets/forecast-os): routing and agent defaults in `skills/forecast-os/SKILL.md`; workflows in `skills/forecast-os/workflows/` (`quote-and-buy.md`, `manage-positions.md`, `create-precog-market.md`, `fund-launchpad.md`); command map and gotchas in `skills/forecast-os/references/`. ## Capabilities - Search live odds across Polymarket, Kalshi, and Precog; quote before buying. - Create and fund a market to obtain real info when none is available. - Fund Precog launchpad (upcoming) markets; claim investment and incentive rewards after deploy. - Manage positions: list, sell, claim (Kalshi settlements are automatic). - Safety: quote/preview first, `--confirm` only after approval, secrets via env vars or key files, never invented keys.
