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.

App Store description

magma is an audio processor that grabs incoming audio and twists its presence throughout time, blends it with its past self, unravels its most recondite shades and controls its weight in space, creating everything in between dark drones, shimmery textures and weird percussive timbres. at the very crossroad between a micro-looper, a granular engine, a sustainer, and a sound warmer, magma can squash your sounds with reverb-like, big shaking auras, or sprinkle air and make your lines ethereal. simply load magma on your track and give your sounds a new identity. magma is a sound processor with its very own character. magic when paired with acoustic sounds, it can transfigure all kind of sources in unexpected ways: it will react differently, according to the input you feed it with. it can either magnify or disintegrate. magma can be molten lead, screaming metal, frozen wind. you will handle magma with care, paying attention on how each parameter acts, according to different contexts. magma will carry your sound around unexplored territories. how it works magma continuously records the incoming signal in a short buffer, it then plays back the content by blending different moments in time, creating a texture. user can set the density and the persistence of the texture, that can sound as a reverb, an infinite sustain, or a sort of spectral shadow. several parameters let user sculpt the texture: an eq section, a temperature knob (a specifically designed distortion adds a noise-based amplitude modulation on higher values), and a mid/side knob to handle its weight in space. go raw or keep it smooth /// the raw switch disables an envelope follower applied to the input by default. set it on for a sharpen sound, or off for a smooth texture. memories and frozen time /// choose how much persitent memories should be, and let magma blend past with present; enable the freeze toggle for an organic infinite sustain. speed /// set the playback speed of memories to harmonize the present with perfect and odd intervals. sculpt /// use the intuitive eq section to boost/cut hi and low frequencies and get the perfect timbre for your texture. weight /// we included a classic mid/side operator; you’ll love how it can sculpt the texture, giving weight or adding air to it! in-gui infos /// enable infos toggle to get all parameters details always in sight; just hover on a parameter. 2 flavours /// dark and light skin. *** please note: magma is an audio unit extension (auv3) – it only works in an auv3 host app like aum, drambo, cubasis, etc... ***

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.
