Claude Code
What it is
Claude Code is a terminal-native coding agent from Anthropic that understands your whole repo and makes edits, runs tests, and opens PRs.
Why people use it
- Repo-aware: reasons across the whole codebase, not one file.
- Agentic: plans, edits, and verifies via real commands.
- Now has a free tier, lowering the barrier to try.
Watch-outs
- Token cost at scale; set budgets.
- Agentic edits need review — don't auto-merge blind.
