Overview

Claude Code handles the tedious tasks that eat up your day: writing tests for untested code, fixing lint errors across a project, resolving merge conflicts, updating dependencies, and writing release notes.

```bash theme={null}
claude "write tests for the auth module, run them, and fix any failures"
```

Describe what you want in plain language. Claude Code plans the approach, writes the code across multiple files, and verifies it works.

For bugs, paste an error message or describe the symptom. Claude Code traces the issue through your codebase, identifies the root cause, and implements a fix. See [common workflows](/docs/en/common-workflows) for more examples.

Claude Code works directly with git. It stages changes, writes commit messages, creates branches, and opens pull requests.

```bash theme={null}
claude "commit my changes with a descriptive message"
```

In CI, you can automate code review and issue triage with [GitHub Actions](/docs/en/github-actions) or [GitLab CI/CD](/docs/en/gitlab-ci-cd).

The Model Context Protocol (MCP) is an open standard for connecting AI tools to external data sources. With MCP, Claude Code can read your design docs in Google Drive, update tickets in Jira, pull data from Slack, or use your own custom tooling. The MCP quickstart connects your first server end to end.

CLAUDE.md is a markdown file you add to your project root that Claude Code reads at the start of every session. Use it to set coding standards, architecture decisions, preferred libraries, and review checklists. Claude also builds auto memory as it works, saving learnings across sessions without you writing anything.

Create [skills](/docs/en/skills) to package repeatable workflows your team can share, like `/review-pr` or `/deploy-staging`.

[Hooks](/docs/en/hooks) let you run shell commands before or after Claude Code actions, like auto-formatting after every file edit or running lint before a commit.

Spawn multiple Claude Code agents that work on different parts of a task simultaneously. A lead agent coordinates the work, assigns subtasks, and merges results.

To run several full sessions in parallel and watch them from one screen, use [background agents](/docs/en/agent-view). For fully custom workflows, the [Agent SDK](/docs/en/agent-sdk/overview) lets you build your own agents powered by Claude Code's tools and capabilities, with full control over orchestration, tool access, and permissions.

Claude Code is composable and follows the Unix philosophy. Pipe logs into it, run it in CI, or chain it with other tools:

```bash theme={null}
# Analyze recent log output
tail -200 app.log | claude -p "Slack me if you see any anomalies"

# Automate translations in CI
claude -p "translate new strings into French and raise a PR for review"

# Bulk operations across files
git diff main --name-only | claude -p "review these changed files for security issues"
```

See the [CLI reference](/docs/en/cli-reference) for the full set of commands and flags.

Run Claude on a schedule to automate work that repeats: morning PR reviews, overnight CI failure analysis, weekly dependency audits, or syncing docs after PRs merge.

* [Routines](/docs/en/routines) run in the cloud, so they keep running even when your computer is off. They can also trigger on API calls or GitHub events. Create them from the web, the Desktop app, or by running `/schedule` in the CLI.
* [Desktop scheduled tasks](/docs/en/desktop-scheduled-tasks) run on your machine, with direct access to your local files and tools
* [`/loop`](/docs/en/scheduled-tasks) repeats a prompt within a CLI session for quick polling

Sessions aren't tied to a single surface. Move work between them as your context changes:

* Step away from your desk and keep working from your phone or any browser with [Remote Control](/docs/en/remote-control)
* Message [Dispatch](/docs/en/desktop#sessions-from-dispatch) a task from your phone and open the Desktop session it creates
* Kick off a long-running task on the [web](/docs/en/claude-code-on-the-web) or the [Claude mobile app](/docs/en/mobile), then pull it into your terminal with `claude --teleport`. Teleport requires a claude.ai subscription.
* Run `/desktop` to continue your current terminal session in the [Desktop app](/docs/en/desktop), where you can review diffs visually. The `/desktop` handoff requires a claude.ai subscription. Available on macOS and x64 Windows.
* Route tasks from team chat: mention `@Claude` in [Slack](/docs/en/slack) with a bug report and get a pull request back
