Trevin Chow's CLI wrapper for Kalshi's prediction market API adds a local persistence layer that Kalshi's own API doesn't provide. You get historical price tracking, category-level P&L breakdowns, portfolio attribution across market series, and correlation analysis between markets. The public API only returns current snapshots and flat positions, so if you need to answer questions like "how did my politics bets perform versus crypto markets this month" or "which markets moved most since yesterday," you need the local tick store. Commands like portfolio winrate, exposure analysis, and settlement calendars turn raw position data into actual portfolio analytics. Requires Go toolchain to install the binary.

Prerequisites: Install the CLI

This skill drives the kalshi-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
    npx -y @mvanhorn/printing-press-library install kalshi --cli-only
    
  2. Verify: kalshi-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.
