# Delimit OS — the AI developer operating system
# Type 'delimit' to launch the TUI, or 'delimit <command>' for CLI tools
#
# Usage:
#   delimit              → Launch TUI (interactive terminal dashboard)
#   delimit --quick      → Quick status (non-interactive)
#   delimit think        → Trigger deliberation
#   delimit build        → Start autonomous build loop
#   delimit ask <query>  → Ask the swarm
#   delimit lint <spec>  → Lint an API spec
#   delimit init         → Initialize governance in current repo
#   delimit setup        → Configure AI assistants
