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.

Do you rent your tape measure? Do you lease your level? Your tools are yours. BluePunch is no different. Purchase one time and it rides in your pocket to every job, every walkthrough, every final punch. No monthly bill. No login. No expiration date. BluePunch lets you pin punch items directly on the plan, measure areas with precision, enter notes, and export it all so the person doing the work sees exactly what you see. No detail lost. No room for interpretation. It raises the bar for everyone on the project. When every item is documented on the plan with photos and notes, there's no hiding. No more "I didn't know about that" or "nobody told me." It's all right there. Trades want to work with contractors who can effectively deploy their team and minimize return trips. When your punch list is clear, detailed, and on the plan, your subs get it right the first time. Other apps charge $40/month per user for features you'll never use. BluePunch gives you everything you need for a one-time purchase. No subscriptions. No per-seat licensing. No corporate sales calls. Just the tool, at a price that makes sense. Built by a project manager, on the jobsite, for the jobsite. FEATURES: • Drop numbered punch items directly on plans with photos, notes, and trade assignments • Calibrate your scale and measure areas, linear distances, and counts with a precision crosshair • Cloud annotations for architect RFIs and revision notes • Manage all entries in one sheet, filtered by page, trade, or label with color coding • Import multi-page PDF plans with smooth zoom, pan, and folder organization • Export professional PDF punch lists and takeoffs with marked-up plans, summary tables, and your company logo. Export by trade or all items. • Works 100% offline. No accounts, no cloud, no data collection.

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.
