Build it with a coding agent

Paste this into Claude Code, Cursor or Codex and describe your app where it says so. The agent reads the build guide and runs the same checks as the review until the app passes.

I want to build an app to sell on AppKeep (https://appkeep.io/): <describe the app, or the open-source app to port>.

Before writing any code, read https://appkeep.io/docs/build-an-app.md and follow it exactly. It explains how AppKeep apps are built (a Cloudflare Worker using Hono, env.DB and an altstack.json manifest), what's allowed, and what gets rejected.

1. If this folder has no altstack.json yet, run `npx appkeep create <app-name>` and work inside the folder it makes. It contains AGENTS.md (the same guide) and SECURITY-REVIEW.md.
2. Build the app. Declare every outbound host, connection, setting and AI tool in altstack.json, each with a reason.
3. Go through SECURITY-REVIEW.md for everything that touches sign-in, public routes, AI tools, connections, settings or database queries.
4. Run `npx appkeep check`. If it says you're not logged in, run `npx appkeep login` and I'll approve it in my browser. Fix every item marked ✕ and run check again until it passes.
5. Show me what you built and the final check output. Don't run `npx appkeep publish` until I say so.
