Claude Code
Anthropic's CLI coding agent — the original Watchfire backend.
What is Claude Code?
Claude Code is Anthropic's official command-line coding agent. It runs locally, reads and writes files in your project, and pairs with Claude models for long-running engineering work. It is the backend Watchfire was originally built around.

Claude Code + Watchfire
Watchfire wraps Claude Code in per-task git worktrees and a platform sandbox, so each session gets its own isolated copy of the repo and a clean transcript. You keep your normal Claude login — Watchfire just appends its project and task prompt at launch time so multiple tasks can run in parallel without stepping on each other.
Install with Claude Code as default
Install Watchfire, then initialise a project that defaults to Claude Code. Make sure the agent CLI is installed and authenticated outside Watchfire first.
watchfire init --agent claude-codeSee the installation guide for platform installers and Homebrew taps.
Interop notes
- Uses your normal Claude install — no separate per-session home directory to manage
- Watchfire appends its project/task system prompt at launch time
- Sign in with Claude Code before using it through Watchfire
