What problem does it solve? Buyers of new apartments from Israeli contractors often miss statutory deadlines because defect periods run from handover, differ by defect type, and differ again for apartments bought before April 2011. This Skill turns a handover walkthrough into a dated defect log, works out which legal window each defect falls in under the Sale (Apartments) Law 1973, and drafts a Hebrew repair-demand letter. ## Core Features & Use Cases - Room-by-room handover checklist: Builds a walkthrough list and converts findings into a dated defect log to attach to the handover protocol (protokol mesira). - Statutory window calculator: The defect_window.py script computes the bedek period, warranty period, burden of proof, and notice deadline for each defect type under both the current and pre-2011 schedules. - Hebrew demand letter drafting: Produces a repair-demand letter that preserves the contractor's statutory opportunity to repair, plus escalation guidance for the Registrar of Contractors, self-repair, and civil claims. - Use Case: A buyer who took possession in March 2021 discovers a pipe leak in January 2026 and assumes it is too late. The Skill calculates that the defect sits inside the warranty period, explains that the burden of proof has shifted to the buyer, and drafts the demand letter to send immediately. ## Quick Start Ask the assistant to check whether a construction defect in your new Israeli apartment is still within its statutory period, giving the handover date, contract date, discovery date, and defect type.
