# ── Recoil Workspace Launcher ──
#
# One-command startup for the Recoil Workspace POC.
#
# Usage:
#   ./workspace/start_workspace.sh [project]
#   ./workspace/start_workspace.sh tartarus
#   ./workspace/start_workspace.sh the-afterimage --port 8450
#
# Port allocation: Pre-Prod=8420, Production Console=8430, Workspace=8450
#
# What it does:
# 1. Checks Python dependencies (fastapi, uvicorn)
# 2. Starts the FastAPI workspace server
# 3. Opens the browser
# 4. Prints MCP configuration instructions
#
# The MCP server (mcp_server.py) is NOT started here — it's started by
# Claude Code via the .claude.json mcpServers configuration.
