4 Primary agents (Coder, Architect, Planner, Shell), 4 Subagents (@reviewer, @general, @explore, @scout), and 3 system agents. Full primary + subagent system with @mention support.
File ops, search, git, web, LSP, code generation, sandboxed execution, clipboard, skills, and more — all built in and ready.
Shell command analysis, permission rulesets (ALLOW/DENY/ASK), rate limiting, API key management, billing system, and path traversal protection.
Switch between any model mid-session without restarting. Compare outputs, optimize costs, and never lose context.

Git-based snapshot system creates automatic backups before every destructive action. Undo/redo with full diff computation. Never lose work again.

01 · Terminal Agent
Same loop as Claude Code or Codex CLI. It reads, edits, runs tests, reports back.
02 · Sandbox Protection
Coder asks, Architect reads, Planner observes. Sandboxed via landlock (Linux), seatbelt (macOS), restricted tokens (Windows).
03 · Model Freedom
Use any LLM from any provider. Swap with /model command mid-session. Structured messages with Parts, snapshots with undo/redo, and custom commands.
Rendered with APEX architecture standard syntax.
