Claude Code

Claude Code is an agentic coding tool created by Anthropic. It reads your entire codebase, edits files, runs commands, and integrates with your development tools. It works in the terminal, IDEs (VS Code, Cursor, JetBrains), a desktop app, the browser, and Slack — all surfaces use the same underlying engine, so CLAUDE.md files, settings, and MCP servers work consistently everywhere.

History

Claude Code was announced on February 24, 2025 as a limited research preview, alongside the Claude 3.7 Sonnet model. It reached general availability in May 2025 with Claude 4. On October 20, 2025, Anthropic launched a web version of Claude Code and a sandboxing feature. The tool gained significant popularity during the 2025-2026 winter holidays.

Capabilities

  • Agentic search — understands project structure and dependencies without manual context-file selection.
  • Coordinated multi-file edits, bug fixing, writing and running tests, refactoring.
  • Git workflow — stages changes, writes commit messages, creates branches and pull requests. In CI: GitHub Actions, GitLab CI/CD.
  • Computer use (since March 2026) — opens apps, navigates the browser, runs dev tools.
  • Agent teams and dynamic workflows — execution across tens to hundreds of parallel sub-agents with result verification. Agent SDK for building custom agents.
  • Customization via CLAUDE.md, skills, hooks, and integration with external data sources through MCP (Model Context Protocol).

Security and control

Claude Code runs locally in your terminal and talks directly to the model APIs, with no backend server or remote code index. It asks for permission before making changes to files or running commands. It works on macOS, Linux, and Windows.

Notes
Upd. 18 Jun 2026

Claude Code runs locally in the user's terminal and communicates directly with the Anthropic API (Claude API), Amazon Bedrock, or Google Vertex AI - with no intermediary backends or remote code index. Zero Data Retention (ZDR): default 30-day retention of prompts/responses for all plans; Enterprise customers can negotiate ZDR with retention limited to 24h (for abuse detection only). Training on data: user code is NOT used to train Anthropic models by default (opt-in only). Tool permissions: every shell command execution, file edit, or MCP call requires user consent (permission prompt) - --allowlist / --deny-list modes exist along with auto-approve for whitelisted commands. Authentication: OAuth 2.0 (Claude Console) or API key. SSO/SAML + SCIM available only on Team/Enterprise plans. Compliance: SOC 2 Type II, ISO 27001, ISO 42001, HIPAA BAA (Enterprise), GDPR-ready, CCPA. Sub-agents run in isolated subprocesses with their own context window - they have no access to the main context or session.
