A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
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.

When played as a solo instrument, the tabla is accompanied (usually on the harmonium or sarangi) by a continuous cyclical musical phrase or riff called the "Lehra" or "Nagma" (ostinato in western music) that keeps track of the "aavartan" or rythmic cycle in the chosen "taal". ________________________________________ ◆ AND NOW PRESENTING - iLehra ◆ iLehra was the first electronic Lehra / Nagma player for the iPhone and iPod Touch, and its now available on the iPad as well! It provides accurate as well as pleasing lehra accompaniment for a wide variety of taals and raags on the Harmonium, Santoor, Violin, or the Flute. Innovative features include tanpura auto-tuned to the chosen lehra/raag, presets, tap-tempo, metronome, and extremely intuitive controls. See the iLehra website for a YouTube demo: http://iLehra.com ________________________________________ ◆ KEY FEATURES ◆ √ Plays 109 Lehras in 55+ raags for 25 taals √ Taals included: Ada Chautaal(14), Basant Taal(9), Chartal-ki-Sawari(11), Chautaal(12), Dadra(6), Deepchandi(14), Dhamar(14), Ektaal(12), Faradost/Firdost(14), Ganesh Taal(21), Jhaptaal(10), Jhoomra(14), Keherva(8), Matta Taal(9), Pancham Sawari(15), Rudra Taal(11), Rupak(7), Sooltaal(10), Teentaal(16), as well as general lehras for 7.5, 8.5, 9.5, 10.5, 13, and 18 beats. √ Beautiful, realistic lehras on Harmonium, Violin, Flute, or Santoor! √ Full octave of pitch adjustments from C through B √ INTEGRATED AUTO-TUNER: Auto-Tune iLehra to your tabla, or use it to tune other instruments (microphone capability required such as iPhone built-in mic or 2nd/3rd generation iPod Touch with external microphone) √ BACKGROUND PLAY: Start playing the lehra and switch to another app, or play along with iPod music √ TAP TEMPO: just tap the beats on the bottom display and watch iLehra sync up! √ PRESETS: save your frequently-used combinations of pitch, taal, lehra, instrument & tempo as named presets.

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.
