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

Unlike the majority of system-based HTTP proxy capture software, Hodor is a packet capture tool based on the IP layer protocol. Consequently, Hodor is capable of capturing HTTP data traffic that many other capture software cannot, including the data traffic from Flutter apps. Hodor provides many useful features, including: - Packet capturing & rewriting with support for HTTP, TCP, UDP, and WebSocket data protocols. - Capturing and rewriting Flutter app traffic. - Support JavaScript extensions - HTTPS decryption to view decrypted data. - Mapping (i.e., replacing) data in HTTP requests and responses. - HTTP replaying and simulating requests and responses for server debugging without using the client again. - Formatting preview for Protobuf, Form-Data, JSON, HTML, JavaScript, and CSS. - Forwarding HTTP requests to other network tools within the local network for data processing (including traffic from Flutter apps). - Domain filtering to only view requests and responses from specific domains. - URL Scheme support for controlling the start and stop of packet capturing with commands. Hodor is an incredibly useful web debugging tool that can help you easily resolve various issues, making your work more efficient and enjoyable. Whether you are a developer or a tester, you can benefit from Hodor. Give it a try now! Automatic Subscription Service Rules 1. If you subscribe to the automatic renewal service through your Apple ID and do not actively cancel the automatic subscription service during the subscription period, Hodor will automatically deduct the next subscription fee from the balance of the Apple ID account linked to the automatic renewal service 24 hours before the current subscription period expires (subject to the actual Apple billing rules). You should pay attention to the balance and payment status of the account. If the renewal fails due to account issues or insufficient balance, you will bear the risk and/or loss by yourself. For your convenience, Apple will notify you of the upcoming deduction before processing the payment. It is important to note that based on the nature of the automatic renewal service, if you do not explicitly cancel the automatic renewal service during the subscription period, Apple will issue a deduction instruction to the relevant parties based on your permission. Generally, any fees deducted based on this instruction will not be refunded. 2. Hodor Pro Subscription Period: 1 year. 3. Hodor reserves the right to adjust service prices or stop providing automatic renewal services. If you do not agree with the adjusted service price, you can cancel the automatic renewal service according to these rules. If you do not cancel the automatic renewal service, the subsequent fees deducted by Apple will be adjusted to the new service fee. 4. The method to cancel the automatic subscription service is as follows: open the Apple iOS device "App Store" -> click on the Apple account profile picture in the upper-right corner -> enter "Account" -> click on "Subscriptions" -> select "Hodor" -> cancel the subscription. 5. Hodor may stop providing you with automatic renewal services according to operational needs. Your Hodor service period will end on the date of the expiry of the current service cycle. * Privacy Policy https://ximlu.github.io/hodor/privacy_en.html * Terms of Service https://ximlu.github.io/hodor/terms_en.html

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.
