# Start the brainstorm server and output connection info

# Usage: start-server.sh [--project-dir <path>] [--host <bind-host>] [--url-host <display-host>] [--foreground] [--background]
|
|
#
|
|
# Starts server on a random high port, outputs JSON with URL.
|
|
# Each session gets its own directory to avoid conflicts.
|
|
#
|
|
# Options:
|
|
# --project-dir <path> Store session files under <path>/.superpowers/brainstorm/
|
|
# instead of /tmp. Files persist after server stops.
|
|
# --host <bind-host> Host/interface to bind (default: 127.0.0.1).
|
|
# Use 0.0.0.0 in remote/containerized environments.
|
|
# --url-host <host> Hostname shown in returned URL JSON.
|
|
# --foreground Run server in the current terminal (no backgrounding).
|
|
# --background Force background mode (overrides Codex auto-foreground).
