failed to spawn `claude`: {e}

Error message

failed to spawn `claude`: {e}

What it means

Spawning the `claude` CLI process failed at the OS level (command not found, permission denied, exec format error). The binary path was resolved earlier, so this is exec-time failure: the resolved path is not executable or the environment cannot launch it.

Solutions

1. Verify the claude CLI binary exists and is executable at the resolved path
2. Reinstall or re-link the Claude Code CLI
3. Check the exec error kind in the wrapped error
