Claude Code: understand a project and carry out development tasks
Learn how Claude Code works with project files and commands, choose a small first task, and understand skills and MCP connections.
What does it do?
Claude Code reads project code, edits files and runs commands for feature work, debugging and checks. Official entry points include the terminal, editors, desktop and web, with setup requirements that differ by entry point.
Which task fits?
Use a focused task in an existing project, such as investigating an error or explaining a module. When a change spans several files, agree on its scope and review the result.
How do you get started?
Check current official access and cost guidance. This website has not installed or tested the tool for you.
- Choose an entry point from the quickstart and check operating system and account requirements.
- Open a project, ask for an explanation and approach, then give a concrete change.
- Review diffs and command output and run project checks before keeping the result.
Where do skills and MCP fit?
Skills provide repeatable task instructions and resources; project instructions can record team conventions. MCP connects external tools and information. Choose extensions for the task and verify client configuration rather than installing everything at once.
