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.

Edit HTTP Headers for Safari is a Safari extension that lets you create rules to set or remove HTTP request headers for specific websites. Use it when you need Safari to send a custom header before a page, script, image, iframe, stylesheet, font, media file, or XHR/fetch request loads. Features: · Create Custom Header Rules: Add HTTP header rules for the websites you choose. · Set Request Headers: Replace or add a header value before Safari loads a matching request. · Remove Request Headers: Remove selected headers from matching requests when you do not want them sent. · Per-Website Rules: Create different header rules for different domains. · Resource Type Controls: Choose exactly where a rule applies, including main pages, iframes, scripts, images, stylesheets, fonts, media, and XHR/fetch requests. · iCloud Sync: Keep your header rules synced across iPhone, iPad, and Mac. · Privacy-first design: No data collection, tracking, or logging, your browsing stays completely private. · Multilingual support: Use the extension in multiple languages for a globally friendly experience. · Clean, user-friendly UI: Enjoy a streamlined design that integrates smoothly into your workflow. · Seamless Safari integration: Built to work across Safari on macOS, iOS, and iPadOS. Common Uses: · Test Mobile User Agents: Send an iPhone, iPad, or desktop User-Agent header to test how a website responds. · Set Language Headers: Ask a website to show content in a different language by changing the language header. · Test API Requests: Add custom headers used by development, staging, or internal tools. · Debug Website Behavior: Compare how a site behaves when certain request headers are added, changed, or removed. · Remove Unwanted Headers: Stop selected headers from being sent to specific websites. · Per-Site Development Setup: Keep different header rules for different domains, test servers, or environments.

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.
