What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Passeporté reads the NFC chip in your biometric passport or national eID card, verifies its authenticity, and stores the data securely on your device. WHY PASSEPORTÉ? • Keep a secure backup of your passport in case it's lost or stolen abroad — have your details ready for the embassy • Store your family's passports in one place before a trip — no shuffling documents at check-in • Check visa eligibility and entry requirements instantly — your passport number, nationality, and expiry are always at hand • Verify a passport is genuine and not tampered with — useful for landlords, notaries, or HR onboarding • Know exactly when documents expire — get alerts months ahead so you never miss a renewal before a trip • Fill out booking forms, visa applications, and hotel check-ins faster — no digging out the physical document every time • Keep a record of your old passports for visa history or proof of prior travel SCAN Point your camera at the passport data page to read the MRZ automatically, or enter details manually. For eID cards, enter the 6-digit CAN from the front of the card. READ VIA NFC Hold your device against the passport or eID card. Passeporté reads the chip using BAC (passports) or PACE (eID cards) and retrieves your photo, personal details, MRZ, and signature. VERIFY Passive Authentication verifies data integrity using the chip’s digital signature. Active Authentication confirms the chip is genuine and not cloned. STORE SECURELY All document data is encrypted using the Secure Enclave with biometric protection. Data never leaves your device — no cloud, no backups, no network access. EXPIRY ALERTS Get notified 6 months, 3 months, and 1 month before your documents expire. Never be caught off guard at the airport. PRIVACY FIRST • No internet connection required or used • No analytics, no tracking, no telemetry • Encrypted with Secure Enclave (P-256 + ECIES) • Biometry-gated access — changing biometrics erases all data • No iCloud, no backups, device-only storage

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
