Second Take

Preview, approve, and recover assistant bookings.

A software-only Alexa+ experience simulation with MCP tools and persistent action history. It helps users change part of a booking, recover a lost confirmation without duplicates, and protect their own edits.

Features

• Workshop plans with camera rental and an in-app calendar event.

• Simulated restaurant, appointment and event reservations through conversation or forms.

• Exact approval before booking, changing or cancelling; editable previews and field comparisons.

• Three recovery stories: lost confirmation, a newer human edit, and partial cancellation.

• Saved evidence, HTML receipts and calendar snapshots.

Prototype scope: services are simulated; no real businesses are contacted. Conversation uses a guided parser. Calendar downloads do not synchronize automatically. The optional Bedrock adapter has not been verified with live AWS calls.

Run locally

Requires Node.js 24 and pnpm 11.25.0. No API key is needed for guided mode.

git clone https://github.com/ArhamChoudhary-ui/Second-Take.git
cd Second-Take
corepack enable
corepack pnpm install --frozen-lockfile
corepack pnpm build
corepack pnpm db:local
corepack pnpm start -- --port 3000

Open http://127.0.0.1:3000 for the workspace or http://127.0.0.1:3000/demo for recovery stories. Local Wrangler simulates the Worker and D1 database. Clearing browser cookies starts a separate workspace.

Try: “Book a restaurant in Jaipur tomorrow at 7 pm for 2 people.”

Verify

corepack pnpm typecheck
corepack pnpm test
corepack pnpm build
corepack pnpm verify:worker

The release suite contains 47 tests. Compiled Worker checks exercise the HTTP/MCP booking and recovery flows. GitHub Actions runs the verification workflow on pushes and pull requests. See the test report for tested behavior and remaining gaps.

Project structure

Technical details

React, TypeScript, Vinext, Cloudflare Workers and D1. The browser calls ten MCP tools at /api/mcp, using Streamable HTTP and protocol version 2025-11-25. Approval revisions, stable resource identities and optimistic version checks enforce the booking rules.

The hosted prototype currently requires owner access. Use the local setup above to run your own copy. The public source retains logical runtime bindings without the original private Site identity.

For optional server-side Bedrock configuration, see .env.example. Workshop interpretation can use that adapter; the other reservation flows remain guided. See security boundaries before connecting real providers.
