📦 Inside the Repo
github.com/google/skills — 124 official Agent Skills, "small instruction files with Google's current best practice that your AI reads before doing a job." 18,700+ stars, Apache-2.0, updated daily. 0:19
The shelves: a getting-started shelf, a whole AI section (the Gemini API skill behind two of the demos), infrastructure (Cloud Run), security (Google's own review checklist), and at the bottom — "a shelf most people scroll right past" — official Google Ads and Google Analytics skills. 0:48
Install is one command:
npx skills add google/skills — or just download the single file you want. "Each skill costs about 5,000 tokens and loads only when the topic comes up." 1:14
🔓 The One-Sentence Technique
"Here's the part that makes this for everyone, not just coders. You don't need a terminal." 1:25
In the Claude app, using a skill is one sentence: attach the skill file → say what you want → send. "That's the entire technique." 1:30
📸 Run 1: Photos → Tables
"The one you'll use tomorrow." A photo of a genuinely messy handwritten note + Google's Gemini skill → a clean table. 1:44
What it did: planned the job, read the handwriting, output task/category/timing columns — "it even worked out that 'Saturday' means August 29th, and flagged the cake order as urgent because of the exclamation mark." Then it handed back a reusable script so it works on any photo. "Whiteboards, sticky notes, shopping lists — photos in, spreadsheets out, forever." 1:56
🎨 Run 2: Images from a Sentence
Same pattern: attach the skill, ask for an image tool. 2:21
What it did: "it picks Google's designated image model, Nano Banana Pro, tells me the faster/cheaper one, and writes the whole tool as a file I can download." One line — "a tiny cozy coffee shop at night" — produced a real 722 KB image. "Thumbnails, birthday invites, product shots, from a sentence." 2:26
🔐 Run 3: Google Security Review
"The sleeper. If you've ever vibe-coded an app, this one's for you." Attach Google's security skill + your app, ask one question: "is this safe?" 3:07
What it tore through (ranked, each with the exact fix): a hard-coded payment key · an
eval on a webhook (remote code execution, rated critical) · an admin page with no login · an SQL injection inside it. "Straight from Google's own security checklist. No cloud account, no sign-up, nothing but your files." 3:19
📚 The Rest of the Shelf
| Skill | What it does |
|---|---|
| Live API | Scaffolds a realtime voice assistant (listens and talks back) |
| Analytics | Answers your website's numbers in plain English as reusable reports (GA4) |
| Cloud Run | Puts what you build on a real public link — "including the roles/run.builder grant almost everyone misses" |
| Google Ads API | Official skills — "that one's for the marketers" |
| The other ~100 | "Deep enterprise plumbing. Skip those." |
