Claude Code in Action

Trust Claude Code With Work You Didn't Watch

Claude Code can finish a quick task in a single prompt. The hard part is handing it hours of work, walking away, and trusting what you find when you get back. That gap is what this course closes. You'll work inside a real project the whole way through, and because DataCamp provides a ready-to-use environment, you'll run actual Claude Code sessions from the very first exercise, with no installation or API key required. This course picks up where an introduction leaves off, so you should already be comfortable running Claude Code and pointing it at a project.

Steer a Long Session Before It Drifts

Long runs fail quietly, and the fixes are all things you do rather than things you hope for. You'll scope multi-file work with plan mode, reading the plan and pushing back on it before a single file changes. You'll direct compaction so the summary keeps the thread you name instead of whatever Claude picks. You'll use the rewind menu to undo a wrong turn or compress a long setup phase, set a goal when you can describe "done" more precisely than the steps, and run parallel sessions in worktrees without them clobbering each other.

Configure Claude So It Actually Follows

Claude follows a lean set of instructions far more reliably than a long one. You'll cut a bloated CLAUDE.md down to rules specific enough to check, and learn why imports organize a file without shrinking what loads. You'll package repeated procedures as skills, where the description is the trigger that makes one fire on its own. You'll match the permission mode to the job, from hands-on editing to unattended pipelines. And you'll move the rules Claude must never skip into hooks — code that runs, refusing a push to main outright, or rewriting a command to strip a live API key while letting the work continue.

Hand the Work Off Entirely

Once you trust Claude with a task, stop doing it by hand. You'll schedule prompts as routines that run on Anthropic's infrastructure with nothing for you to host, and learn the guardrails that make an autonomous run safe to leave alone. You'll drop to headless mode when a job needs your own pipeline, shaping output to a JSON schema so the next script can read it. You'll see where the Agent SDK fits when the work belongs inside your own application, and put Claude on pull requests with managed Code Review and the GitHub action.

Verify What Came Back, Then Share It

A run nobody watched needs a real check, not a tidy summary. You'll read the diff rather than the write-up, and see why a clean summary can sit on top of a change nobody asked for. You'll gate the end of a turn on a real type check with a Stop hook, so Claude cannot finish on a broken build. You'll get a cold second opinion from a session with no memory of how the code was written. Finally you'll package the setup you trust — skill, hooks and all — as a plugin your whole team installs in one step.

By the end you'll be able to point Claude Code at hours of work, walk away, and check the result with confidence.
