Claude Code: Core

A standalone essentials course for Claude Code, the agentic coding tool. Learners drive real coding tasks from the terminal - context setup, multi-file edits, test runs - while keeping human review in the loop.

What this course covers

The course runs across 8 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.

  • Introduction to Claude Code and Terminal Workflows — Learn how to install, authenticate, and initialize Claude Code in your terminal, and understand the basic command structure and interactive shell.
  • Establishing and Managing Project Context — Understand how Claude Code indexes codebases, how to use ignore files to control context, and how to explicitly guide the agent to relevant files.
  • Guided Lab: Exploring an Unfamiliar Codebase — A hands-on guided exercise using Claude Code to search, map, and document the architecture of an existing project directly from the terminal.
  • Executing Safe Multi-File Edits — Master the syntax and prompting techniques required to direct Claude Code to make coordinated, multi-file code modifications safely.
  • Guided Lab: Implementing a New Feature — A hands-on guided lab where you prompt Claude Code to implement a specific functional requirement across multiple source files.
  • Running Tests and Interactive Iteration — Learn to execute test suites through Claude Code, interpret the tool's feedback, and guide it to iteratively fix failing tests.
  • Review Discipline: Evaluating Agent Proposals — Develop the critical evaluation skills needed to analyze proposed diffs, catch subtle agent errors, and manage the human-in-the-loop approval workflow.
  • Guided Lab: The Complete Edit, Run, and Review Cycle — A comprehensive, end-to-end capstone exercise where you manage a complex refactoring task from initial prompt to final verified commit.

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

Anyone comfortable in a terminal; developers and technical users. The material is pitched at intermediate level, and takes roughly 120 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: Claude 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 guided lab, branching scenario exercises. There is no video to sit through and no slide deck to click past.

Understanding is checked with a tool 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.

  • Claude: Core — Projects, Artifacts & Claude Code — An advanced course for using Claude on complex, repeatable, and technical work. Learners apply custom instructions, build interactive Artifacts, use Claude Code, and connect tools through MCP for long-context workflows. The outcome is the ability to run sophisticated, multi-step work in Claude.
  • Claude Cowork: Core — Connectors, Skills & Scheduled Tasks — Move from single tasks to connected work. Learners plug Cowork into email, calendar, documents, chat and CRM tools, use ready-made skills and plugins for their role, drive websites through the browser, schedule recurring work, and assign tasks from anywhere — while handling actions in live systems responsibly.
  • Claude: Essentials — A practical introduction to getting real work done with Claude. Learners navigate the interface and models, write effective prompts, organize work in Projects, and create documents and apps with Artifacts. By the end they can confidently use Claude for everyday writing, analysis, and research.
  • Claude: Essentials — Data & Analysis Playbook — A focused, 30-minute playbook for doing data and analysis work in Claude. Learners run real tasks end to end - data cleanup, analysis, charts, and interpretation - and leave with repeatable workflows they can use the same day.
  • Claude Cowork: Essentials — A practical introduction to getting real work done with Claude Cowork. Learners connect folders, set the right permission mode, describe outcomes instead of steps, and produce finished documents, spreadsheets and research from their own files — while learning to review, correct and stay in control.
  • Claude Essentials Proficiency — Measures whether someone can frame a long piece of work for Claude, give it the right source material, and judge the answer that comes back.
