When you commit, Entire writes a checkpoint with the full transcript, file changes, tokens, and tool calls to the `entire/checkpoints/v1` branch — no extra commits on your working branch. The default agent is Claude Code. To choose a different one, run `entire agent add `. ## Built-in agents * **[Claude Code](/agents/claude-code)** — Stable · `--agent claude-code`. Full feature support including nested subagent capture. * **[Codex](/agents/codex)** — Stable · `--agent codex`. Native hook system; main session capture (no subagent hooks yet). * **[Copilot CLI](/agents/copilot-cli)** — Stable · `--agent copilot-cli`. Native hooks; token usage available post-session. * **[Cursor](/agents/cursor)** — Stable · `--agent cursor`. IDE and CLI. Rewind and resume are not available. * **[Factory Droid](/agents/factory-droid)** — Stable · `--agent factoryai-droid`. Subagent-aware capture via `pre-tool-use` and `post-tool-use` hooks. * **[Gemini CLI](/agents/gemini-cli)** — Stable · `--agent gemini`. File changes captured; conversation transcript and token tracking are limited. * **[OpenCode](/agents/opencode)** — Stable · `--agent opencode`. TypeScript plugin integration; supports mid-turn commits. * **[Pi](/agents/pi)** — Preview · `--agent pi`. TypeScript extension integration with JSONL transcript and token capture. Any agent can be added by writing an executable named `entire-agent-` and placing it on your `$PATH`. The Entire CLI auto-discovers it.
