Gemini for Developers: Essentials — Code Review Playbook

A focused playbook for reviewing code with Gemini. Learners review a pull request written by a coding agent for correctness, security, risky edits and missing tests, ask for specific line-referenced findings, then check Gemini's review instead of trusting it. They leave with a reusable review prompt and the habit of verifying every finding before it becomes a comment. About 45 minutes including the final.

What this course covers

The course runs across 3 topics, each one a short adaptive session rather than a recorded lecture. The tutor explains the idea, works an example, checks understanding, and adjusts the next step to the answer given.

Giving Gemini what a reviewer needs — Learners give Gemini the intent (the refund policy), the diff and the old tests, and ask for findings as a table with file, line, category, evidence and a suggested fix. They see why 'review this' with no policy gets vague, generic advice.
Correctness, security and risky edits in an AI-written PR — Learners look for boundary mistakes, removed authorisation checks, sensitive data written to logs, and tests that were deleted or edited to match the new behaviour. They treat the agent's summary ('all tests pass, no change to existing behaviour') as a claim to check against the diff.
Checking the review: accept, reject or test — Learners decide which of Gemini's findings to accept, which to reject as false positives and which need a test to settle. They turn the accepted findings into short, line-referenced review comments and a request for the missing tests.

Skills you build

Results are measured against named skills in the OneRange taxonomy of more than 10,000 skills, so a manager sees proficiency per skill rather than a completion tick.

Who it is for

Software developers. The material is pitched at beginner level, and takes roughly 45 minutes at a typical pace. Because every session adapts, someone who already knows a topic moves through it quickly instead of sitting through an explanation they do not need.

It sits in the Tool: Gemini track of the Vero AI Catalog, and can be assigned to one person, a team, or the whole company.

How it is delivered and assessed

Delivery is conversational and interactive, including code lab, branching scenario exercises. There is no video to sit through and no slide deck to click past.

Understanding is checked with a lab assessment of 5 items, with a pass mark of 70%.

Administrators can copy this course into their own library and adapt it — edit the outline, change the duration, swap the assessment format, or ground it in internal documentation so answers cite the company's own source material.

Gemini: Essentials — Data & Analysis Playbook — A focused playbook for doing data and analysis work in Gemini. Learners run real tasks end to end - data cleanup, analysis, charts, and interpretation - and leave with repeatable workflows they can use the same day. About 45 minutes including the final.
Gemini for Developers: Essentials — Refactoring & Migration Playbook — A focused playbook for safe refactoring and migration with Gemini. Learners pin down what legacy code must keep doing, rename and extract functions in small behaviour-preserving steps, then move off deprecated Python date helpers without breaking the nightly job. They leave with a step-by-step refactor plan and the habit of checking what the tests do not cover. About 45 minutes including the final.
Gemini: Essentials — Everyday Work — This course applies Gemini to everyday knowledge work: email, documents, meeting prep, and quick research. Learners practice each workflow directly in Gemini and leave with daily habits, not just features.
Gemini: Intro — An absolute-baseline introduction to Google Gemini for first-time users. Learners see what Gemini is, how to open it (including inside Google Workspace), and how to send their first prompt. It gets total beginners started in minutes. About 30 minutes including the final.

Frequently asked questions

How long does this course take?

It runs roughly 45 minutes at a typical pace. Because every session adapts, someone who already knows a topic moves through it quickly instead of sitting through an explanation they do not need.

How is it assigned to a team?

An administrator assigns it from the Vero dashboard to one person, a team, a department or the whole company, and sees progress and results per person and per skill.

Can we customise it with our own documents and terminology?

Yes. Administrators can copy this course into their own library and adapt it — edit the outline, change the duration, swap the assessment format, or ground it in internal documentation so answers cite the company's own source material.
