What problem does it solve? After creating a git worktree manually, you still need to copy the .bonsai configuration files and run package installs before the worktree is usable. This Skill automates that priming step for any worktree that already exists, without requiring you to recreate it through the bonsai CLI. ## Core Features & Use Cases - Worktree Priming: Copies .bonsai files from the canonical checkout into an existing worktree and runs the detected package installs. - Cross-Agent Binary Resolution: Locates the bonsai CLI via BONSAI_BIN, CLAUDE_PLUGIN_ROOT, or the Codex plugin list, so it works in both Claude Code and Codex environments. - Best-Effort Installs: A failed install is reported as a warning rather than a hard error, leaving the worktree usable; --no-install copies files and reports detected install targets without running them. - Use Case: You created a worktree by hand with git worktree add and want it configured like any bonsai-managed worktree. Run setup with the worktree path and the canonical repo root to copy config files and install dependencies in one step. ## Quick Start Ask the agent to run bonsai setup on your existing worktree, providing the worktree path and the canonical checkout root as the --repo argument.
