What is Claude Code?
Claude Code is Anthropic's AI coding agent that runs in your terminal. It reads your codebase, runs shell commands, writes and edits files, and works through multi-step engineering tasks using natural language instructions — without leaving your development environment.
How do I switch between multiple Claude accounts?
Claude Code does not natively support account switching. The open-source claude-swap tool solves this by managing OAuth credential profiles — letting you switch between personal, work, and client Claude accounts from the command line without logging in and out each time.
Can Claude Code automate pull request code reviews?
Yes. Claude Code can be integrated into CI/CD pipelines to automatically review pull requests before human review. Anthropic uses this pattern internally, with Claude flagging security issues, logic errors, and style violations on every PR.
What happened with the Claude Code source code leak in 2026?
In March 2026, DMCA takedown notices submitted to GitHub inadvertently revealed repository names and code snippets from Anthropic's Claude Code codebase. The incident sparked discussion about open-source AI tooling security and supply-chain risks in AI development tools.
