VSMONSTER — Command your AI squad from your phone

Executive Summary

VSMONSTER turns VS Code into an autonomous AI development factory you can control from your phone. 🚀

You text an idea on LINE / Telegram / Discord
→ UFO 🛸 (Gemini 3 Pro Reasoning Engine) breaks it down
→ BlueMonster 👾 (Gemini 3 Pro Parallel Executor) writes code in parallel
→ results are sent back to your phone.

Key innovations:

  • Powered entirely by Gemini 3 Pro (1M+ token context + native multimodal Vision) ✨
  • True parallel execution (5–10 tasks at once) ⚡
  • Full phone-based workflow (no need to sit at desk) 📱
  • Zero extra API cost (runs on your Copilot subscription) 💰

From napkin sketch to production code — while you sleep. 😴

Inspiration

Every developer has been there: you're on the train, in bed, or walking the dog — and suddenly you have an idea or a bug to fix. Traditional AI tools force you to sit at your desk and babysit every prompt.

What if your computer could just… start coding the moment you text it?

That's VSMONSTER.

What It Does

VSMONSTER turns VS Code into an autonomous AI development factory with three core agents:

  • UFO 🛸 (Control Center) — Receives your requests, breaks them into task specs, manages the work queue, and dispatches approved tasks
  • BlueMonster 👾 (Task Worker) — Executes tasks using AI models including Gemini 3 Pro — writing code, running terminals, analyzing images, all in parallel
  • Holography 🛰️ (Message Translator) — Bridges your phone messages (LINE/Telegram/Discord) into commands the system understands

Real-world scenario:

  1. You're walking your dog
  2. You text on Telegram: "Create a REST API with user authentication and write tests"
  3. UFO 🛸 decomposes this into subtasks (schema, routes, middleware, tests)
  4. BlueMonster 👾 executes them in parallel using Gemini 3 Pro
  5. Your phone buzzes: "4/4 tasks complete. Preview ready."
  6. You approve from your phone — code is committed

How We Built It

VSMONSTER is built as three independent modules, all powered by Gemini 3 Pro:

🛸 UFO – Gemini 3 Pro Reasoning Engine
UFO uses Gemini 3 Pro's advanced reasoning to run a "Task Interview" system: analyzes project context, asks clarifying questions, and generates a formal Task Spec with dependency graph before dispatching.

👾 BlueMonster – Gemini 3 Pro Parallel Executor
BlueMonster runs tasks in true parallel. Thanks to Gemini 3 Pro’s native multimodal capabilities, it can directly understand screenshots, UI mockups, and error images sent from the phone.

🛰️ Holography – Gemini 3 Pro Context Bridge
Holography normalizes messages, images, and media from LINE/Telegram/Discord into a unified Gemini context object, allowing Gemini 3 Pro to maintain long-term conversation memory across platforms.

Tech Stack:
TypeScript monorepo (pnpm workspaces) · VS Code Extension API + Copilot SDK · Express + WebSocket · Next.js 14 · LINE Bot SDK / grammy / discord.js

Challenges We Ran Into

  • VS Code Webview CSP: Inline scripts are blocked by VS Code's HTTP-level Content Security Policy, even with correct nonces. Solved by using external JS files loaded via webview.asWebviewUri() and passing configuration through HTML data-* attributes.
  • Parallel task isolation: Each BlueMonster task needs independent state, chat history, and terminal sessions. Built a task isolation system with per-task memory and context switching.
  • Real-time coordination: Synchronizing task status across Gateway, VS Code extensions, and the Mission Control dashboard required careful WebSocket event design and state reconciliation.
  • Security: Ensuring tokens and API keys are never exposed to the AI agent, while still allowing the agent to execute code freely. Implemented whitelist + handshake verification and token detection guards.

Accomplishments We're Proud Of

  • True AFK development — We actually fix bugs and ship features from our phones daily
  • Zero marginal cost — Complex multi-step tasks run on flat-rate Copilot subscription, no per-token billing anxiety
  • Parallel execution — BlueMonster runs multiple tasks simultaneously, unlike traditional one-at-a-time Copilot usage
  • Phone-based code review — Mission Control lets you review diffs, approve tasks, and check media output from mobile

What We Learned

  • The biggest insight: AI agents don't need new interfaces — they need to live where developers already work. VS Code is the world's most popular editor. By making it the "brain" and phones the "remote control", we eliminated the adoption friction that kills most AI tools.
  • Gemini 3 Pro's reasoning capabilities were crucial for task decomposition — breaking "build me a dashboard" into concrete, ordered subtasks is fundamentally a reasoning problem.

What's Next

  • MCP (Model Context Protocol) expansion — Plug in email, browser automation, database management as tools BlueMonster can use
  • Self-evolution system — Let BlueMonster write its own tool scripts when it encounters capabilities it doesn't have yet
  • Voice control — Integration with speech-to-text for truly hands-free development
  • Team mode — Multiple developers sharing a VSMONSTER instance, with role-based task assignment
