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.

You’ve probably heard of the “10,000 Hours” idea. You may also have felt intimidated by it. But the truth is, what matters most is simply starting. The very first second you spend on something meaningful already counts. I built 10,000 Hours as a timer for long-term life projects — not just another Pomodoro app, but a place to keep track of the things you truly want to grow with over time. Whether you’re learning English, practicing handwriting, working out, preparing for exams, writing, or simply trying to stay with a hobby you genuinely care about, you can create your own life project here and keep showing up for it, one session at a time. And as time passes through your hands, you may begin to feel something rare: a quiet sense of steadiness, calm, and real progress. Will it bloom into something wonderful? Most likely, yes. And even if it doesn’t turn out exactly the way you imagined, spending a season of your life doing something with care — and getting to know yourself a little better along the way — is already a gift.

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.
