README

axt — Agent eXtension Tool

A unified CLI & TUI dashboard for managing extensions, plugins, skills, MCP servers, hooks, commands, and agents — and for tracking usage costs — for **Claude Code**.

🌐 한국어: [README.ko.md](./README.ko.md)

**v1.0.0: Claude-only.** The earlier multi-platform line (Codex / Gemini CLI / Cursor) is retained as v0.2.x; v1 drops that surface to focus on Claude depth. See [MIGRATION.md](./MIGRATION.md) (English) or [MIGRATION.ko.md](./MIGRATION.ko.md) (Korean) for upgrade notes.

Python + curses package, pure stdlib runtime. The older TypeScript+Ink line (v0.1.x) lives in git history only — see the `v0.2.0` tag.
