Sublime Claude Code — Development skill for Claude Code

Claude Code IDE for Sublime Text

**English** | [日本語](./README.ja.md)

**Run six Claude Code sessions in parallel and still know what changed where.** Native [Claude Code](https://claude.com/product/claude-code) integration for Sublime Text 4: a **Recent Activity** pane lists every file your sessions touched — grouped project → session → file, one click to open — next to in-editor diff review (accept/reject), live selection sharing and `@`-mentions, over the same WebSocket/MCP protocol as the official VS Code and JetBrains extensions.

**Unofficial community plugin** — not affiliated with or endorsed by Anthropic. "Claude" and "Claude Code" are trademarks of Anthropic, PBC.


**Status: 0.3.x, all features working** — the IDE server with context sharing, in-editor diff review, parallel multi-session support, and the Recent Activity pane are implemented and tested end-to-end against the real Claude Code client ([releases](https://github.com/Cognisant-llc/sublime-claude-code/releases)). Package Control listing is pending; the manual install below works today.

• No bundled AI, by choice. AI-native IDEs (Cursor, Windsurf,
