Dev Builds Theatre Prop Continuity Tracker to Catch Staging Errors

A developer created Prop Continuity Desk, a rehearsal planning web app designed to help small theatre productions track the physical movement of props across scenes. The app is built around a fictional six-scene play with twelve props and detects two key mistakes: placing the same prop in two locations within one scene, and moving a prop between scenes without a recorded transfer cue. It uses Next.js, React, TypeScript, and Sanity as its content backend, with scene reviews stored in separate documents to avoid overwriting the data being reviewed. A practice-copy feature lets visitors explore the rules without altering the live production plan, and any exported cue sheet from a practice session is clearly labelled as such. The project was built using Codex starting 26 September 2026, with the AI proposing the scenario, writing the code, and running the tests under the account owner's authorization.
