Claude Code
Fix one small bug with Claude Code on a Git branch, then review every line
A terminal coding agent that reads your project and proposes edits. Best for a narrow bug or small change in a repository you already version with Git.
Written from the tool's official pages, listed under Official sources at the end of this guide. Check them for current features, limits and terms.
Try it (opens in a new tab)Steps to try
- Pick a project that is under Git, then create a new branch first so the experiment is easy to discard.
- Install Claude Code using the method on the official quickstart for your system, open a new terminal and check that claude --version prints a version.
- Start claude in the project folder and sign in when prompted. Ask it to explain the project before it changes anything.
- Describe one specific bug, including what you see and what you expected, rather than a vague request like fix the bug.
- Read each proposed edit before approving it, and check the permission mode so you know what it may do without asking.
- Run your own tests or build, read the full diff, and commit only what you understand. Ask for tests if none cover the change.
Limitations
It can make confident but wrong edits, so you stay responsible for review and testing. Large or vague tasks work less well than small, specific ones. The official quickstart is a starting point and does not cover your project's quirks.
Pricing
Use requires a Claude subscription, a Claude Console account or a supported cloud provider, according to the quickstart. Plans, usage limits and costs change, so check the official site rather than this guide.
Privacy and data
Claude Code reads project files as needed, so avoid opening folders that contain secrets, customer data or private keys. Keep credentials out of prompts and out of the repository, and follow your employer's rules on sending code to a service.
About the sources
Based on the vendor's published documentation, not hands-on testing. The quickstart does not cover your project's quirks.
Alternatives
Other terminal or editor coding agents exist. Cursor suits people who prefer an editor window; ordinary IDE assistance is a lower-risk start if you are new to agents.
