Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

It’s about helping you achieve real growth, gain skill, control, and obtain a unique sound that earns respect. Drumtune PRO is a tool to help you build lasting drum tuning skills with clear feedback, empowering you to make your own creative sound decisions. • Mastering your kit still takes listening, awareness, and practice. • The tuner shows you where you are pitch-wise, but you make the tuning decisions for your tone & feel. 〉〉TECH SPECS • Patented high-precision tuning engine (0.5 Hz resolution) • Ultra-wide tuning range: 30 Hz to 800 Hz and way up (adaptive by drum type and mode) • Compatible with iOS 15.6 or later and iPhone 8 or newer 〉〉 SUPPORT Question/doutb/bug: [email protected] ⌘ Pro Tip ⌘ Drumtune PRO already has the widest tuning range of any drum tuner app or drum tuner device made so far. • High pitches beyond the tuning range can show as lower pitches within the tuning range. • Respect the natural tension range of your drumhead. Like tuning by ear, apply tension with care. • Use common sense & trust your drummer instinct to never overtighten. Too much tension can snap drumheads, especially thin snare reso heads. • Start at medium snare-reso tension first and increase gradually so the high pitch tracks accurately within range. • When in doubt, or when overshooting the range chasing a pitch, return to medium tension. ► Tune smart, play hard, and trust Drumtune PRO to keep you sounding your best, every session!

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
