Prototype Preflight

About this plugin

Prototype Preflight audits the current page’s prototype graph before testing, usability sessions, or handoff.Run one scan to find:• Missing, deleted, off-page, or unsupported destinations• Invalid flow starting points• Participating screens unreachable from every valid start• Cross-screen scroll targets• Persistent overlays with no modeled escape• Close actions that may never run in overlay context• Interaction sources outside a supported presentation root• Non-blocking review hints for possible terminal screens and closed loopsClick any finding to select and reveal the exact Figma layer. If a success, confirmation, or ending screen is intentional, mark it once and Prototype Preflight will remember that marker in the file.Trustworthy by design:Errors describe broken facts. Warnings identify likely flow problems. Ambiguous endings and loops stay as review hints because they may be intentional. Conditional branches are analyzed as possible paths; the plugin does not claim to prove every runtime variable state or the usability of a design.Private by construction:Prototype Preflight scans only the current page. It has no backend, accounts, analytics, uploads, or external network access. Design data stays inside Figma. The scan is read-only; only an explicit intentional-ending marker writes private plugin metadata to the selected frame.Support: [email protected]
