Agentic coding is how many developers now build software: AI coding agents that read your codebase, edit multiple files, run commands and tests, and work through larger tasks with you.
In this hands-on course, Tom Chant, Head of Education at Scrimba, shows you how to ensure reliable results from a coding agent by giving it the right context, planning work, and controlling permissions, while verifying every change.
You'll work through realistic tasks covering prompting, AGENTS.md, skills, testing, Git, secrets, config.toml and the Model Context Protocol (MCP). This course suits experienced developers adding AI to their workflow and non-coders who wish to build software with AI help.
We'll cover:
- Writing effective prompts and comment prompts for AI coding agents
- Initializing projects and setting persistent instructions with AGENTS.md
- Using Plan Mode to break down larger development tasks
- Extending a coding agent with skills
- Verifying agent changes with characterization tests and test-driven development (TDD)
- Using Git safely alongside a coding agent
- Keeping API keys, credentials and other secrets safe
- Managing context and configuring agents with config.toml
- Controlling what an agent can access and change with permissions
- Connecting agents to external tools with MCP, including shadcn
