I want to set up nix-openclaw on my Mac.
Repository: github:openclaw/nix-openclaw
What I need you to do:
1. Check if Determinate Nix is installed (if not, install it)
2. Create a local flake at ~/code/openclaw-local using templates/agent-first/flake.nix
3. Help me create a Telegram bot (@BotFather) and get my chat ID (@userinfobot)
4. Set up secrets (bot token, Anthropic key) - plain files at ~/.secrets/ is fine
5. Fill in the template placeholders and run home-manager switch
6. Verify: launchd running, bot responds to messages
Reference the nix-openclaw README for module options.
