catchtable-sniper

A reservation-sniping assistant for Catchtable, the Korean restaurant-booking platform, that watches for open or cancellation slots and attempts to book them automatically. It drives a Chrome browser through Chrome MCP and reuses an existing logged-in Catchtable session, so no API key, package install, or credential handling is involved. If the browser is not logged in, the skill stops and asks the user to sign in with Kakao or Naver first, since it never automates login.

Several booking modes are supported. Cancellation-sniping polls a restaurant at a configurable interval (a minimum of thirty seconds, to avoid server load) and books the moment a slot appears. Open-run mode waits for a scheduled reservation-open time and fires at that exact moment, falling back to cancellation-sniping if the slot is already gone. Multi-target mode cycles through up to five named restaurants and grabs whichever opens first, then stops watching the rest. Flexible party-size matching offers an alternative headcount when the requested size is unavailable and asks the user to confirm. Dry-run mode is notify-only, reporting a found slot and leaving the actual booking to the user.

Input parsing extracts restaurant names or URLs, date, party size, an optional time window, mode, flexibility, open time, and polling interval from natural-language requests. The execution flow covers browser prep and login check, mode branching, slot detection, form auto-fill (headcount, visit purpose, agreement checkboxes, and saved reservation info), and a completion screen with the reservation number. Some steps are intentionally left to the human, including login and payment-info entry for prepaid restaurants, where the skill stops and asks before any payment. Default limits are a two-hour watch window and five simultaneous targets.
