Anthropic's 7 Hour Claude Code Course in 27 Minutes
David Ondrej compresses Anthropic's official 7-hour Claude Code masterclass into 27 minutes — with two ground-truth corrections the official course is already wrong about.
January 20th 2026David Ondrej installs Google's open-source coding agent, runs it live against Claude Code on a real production codebase, and lets the results speak.
Three differentiators in one breath — open source, one-million-token context, and a thousand free queries a day — before the title card appears. David Ondrej's cold open on the Gemini CLI GitHub README sets the frame fast: this is a structural threat to Claude Code, even if the polish isn't there yet.

Gemini CLI README with animated >GEMINI logo. Open source + 1M context + 1K free queries/day stated immediately.

npm install -g @google/gemini-cli. Node.js 18+ prerequisite. Three auth paths: Google login (free, data training), API key (paid, no training, always Pro), Vertex AI.

Full-screen card: 60 req/min, 1K req/day, Open Source, Free. Model comparison chart showing Gemini 2.5 Pro context is 5× larger than Claude Opus/Sonnet.

Opens Gemini CLI inside Cursor terminal. Theme selection, /auth flow. Running on real Vectal production codebase (React/TypeScript/Supabase).

Default GEMINI.md is vague 20 lines. Hits 429 rate limit errors with API key mid-demo. Switches back to Google login. Navigates docs to find settings.json configuration trick.

Create .gemini/settings.json with contextFileName: AGENTS.md. Lets you reuse a single highly-optimized prompt file across Gemini, Codex, and Claude Code. Shows his 400-line AGENTS.md now powering Gemini CLI.

Prompt: replace emoji thumbs buttons with Lucide React icons in ThumbsFeedback.tsx. Gemini reads file twice, gets downgraded to 2.5 Flash, request cancelled, no changes applied.

Demo of vectal.ai AI task manager — project-level system prompts, team context, Gemini 2.5 Pro inside the app.

Same prompt, Claude Code. Reads file, applies Lucide React icons with correct green/red coloring, done in one shot. Direct side-by-side contrast.

Claude Code clearly better now. Gemini CLI's open-source fork-ability, free tier, 1M context are structural advantages worth tracking. Less than 24 hours old.

Lists all available tools: ReadFolder, WriteFile, Shell, Memory, GoogleSearch, WebFetch. Runs web search — Gemini searches for news about itself using GoogleSearch tool.

Team plan demo with per-person AI context. CTA: comment 'part two' for advanced video on MCPs, memory, web tools.
Which Gemini CLI auth to use depends on data privacy needs and budget — free users risk getting downgraded to 2.5 Flash at peak times.
Create .gemini/settings.json with contextFileName pointing to your existing AGENTS.md. One optimized prompt file works across Gemini CLI, Codex, and Claude Code.
Gemini 2.5 Pro's 1M context vs Claude's 200K means Gemini is structurally better for large monorepos, even if current quality lags.
“1,000 queries per day. Most people will not even get close to 1,000 prompts a day, which means Gemini CLI, for most of you, will be completely free.”
“Google open-sourcing Gemini CLI — whereas Claude Code and Codex are not fully open-sourced — is a huge power move.”
“Cloud Code was able to one-shot it. No problem.”
“It's been less than twenty-four hours since they released it. So for now, Claude Code is clearly better, but I would keep testing Gemini CLI.”
“If you want me to make another video on it, comment below 'part two' and I'll make it happen.”
Soft engagement CTA seeded earlier at 11:18 and closed out at end. Works because the first video intentionally leaves MCPs, memory, and web tools uncovered.
One settings.json file lets you point Gemini CLI at the same AGENTS.md you already use for Claude Code — no rewriting prompts, instant upgrade.

January 20th 2026Brandon Hancock spends 35 minutes putting Gemini CLI through three live tests — a one-line styling fix, a full memory-feature build, and a from-scratch landing page — and lands on a single rule: Gemini CLI thrives with context, dies without it.
