Read-only interface to Toss Securities accounts through the tossctl CLI. It wraps JungHoonGhae/tossinvest-cli to query account summaries, portfolio positions, stock quotes, order history, and watchlists without touching any trading mutations. Requires macOS with Homebrew and browser-based login through tossctl auth. The defensive design is smart: it won't let you accidentally place orders, explicitly converts relative dates to absolute ones, and minimizes exposure of account numbers. Good for dashboards or automated portfolio reporting in Korean. If the upstream web API changes, you'll need to wait for tossctl itself to update.
