Tokyo Vibe Coders #3

WED, JAN 28 · 7-9PM · MEGURO
Tokyo Vibe Coders #3
TalksFirebase AI
  1. Sumit Chandel (Firebase Genkit & AI Developments)
  • Role: Developer Relations Engineer for Firebase at Google.
  • LinkedIn: Sumit Chandel
  • Talk Summary: Discussed the "existential" transition of software development, positioning us at "Step 1" where we integrate AI into the massive ecosystem of pre-2022 apps. Demonstrated a "friendly movies app" using Firebase Genkit. He showed how to easily add AI features to a standard app by importing the Firebase SDK and configuring the Gemini 3 Flash model.
  • Tools Mentioned:
    • Firebase Genkit (SDK for building AI features)
    • Gemini 3 Flash (Model used for the demo)
  1. Cedric (Human Brain & AI)
  • Role: Computer Science Graduate & Speaker.
  • Linkedin: https://www.linkedin.com/in/cedric-camerman/
  • Slides: View Slides
  • Talk Summary: Focused on the "human bottleneck" in AI-assisted coding: Cognitive Load. Explained that while AI lets you switch roles rapidly (Architect ↔ Developer ↔ Tester), this context-switching drains your brain's energy. Proposed managing your "daily cognitive budget" (or token limit) by treating your brain like a muscle
  1. Prashant Anand (Better Frontend)
  • Role: Machine Learning Engineer (ex-Mercari) & Newsletter Author.
  • LinkedIn: Prashant Anand
  • Talk Summary: Addressed the "Generic UI" problem where AI-generated sites often converge on predictable designs. Shared his workflow using the "Front End Design" skill—an official Anthropic plugin for Claude Code (the CLI tool). This plugin acts as a specialized designer agent that can be installed into your environment to enforce better aesthetics.
  • Tools Mentioned:
    • Claude Code "Front End Design" Skill (The specific skill/plugin mentioned)
    • Agentic Coding Weekly (Prashant's newsletter)
    • Google Anti-Gravity (New local IDE tool mentioned as a "free alternative to Cursor")
    • GitHub Copilot
  1. Sean (LanguageBank)
    • Role: Product Designer. Linkedin: https://www.linkedin.com/in/seanyeoh/
    • Slides: View Slides
    • Talk Summary: Showcased LanguageBank, an iOS app he built to streamline his Japanese learning workflow. Detailed his development process: using OpenAI Whisper for transcribing speech and Supabase for handling authentication and backend data. Shared insights on the "builder" experience: The app took only 5 days to build using AI agents (Cursor), but the App Store review process took longer. He used AI to debug the specific rejection reasons from Apple.
    • Tools Mentioned:
      • Supabase (Used for Auth/Database)
      • OpenAI Whisper (Transcription)
      • Xcode (iOS Development)
      • LangTool (Mentioned for prompt experimentation)

Tools Mentioned at Meetup (Recap)

  • Cursor: The primary AI code editor used by multiple speakers for building apps quickly. Google Anti-Gravity: A new local IDE tool mentioned by Prashant for agentic workflows (often described as a free alternative to Cursor).
  • Claude Code: Anthropic's CLI tool that supports "skills" (plugins) like the Front End Design agent.
  • Figma: Used by Sean for design reference; screenshots were pasted into AI agents to guide code generation.
  • Claude Co-work: Mentioned in the group discussion topics (a desktop UI with cloud CLI features).
  • Codex: Mentioned by Prashant in the context of coding environments.
