Set Up Sentry Development Environment

Walk the user through getting Sentry running locally. The full process from a bare machine takes 30-45 minutes — most of that is downloading dependencies and Docker images. Set expectations clearly at each step.

AL MCP: If the al MCP server is available, use al_search_docs and al_read_doc for detailed troubleshooting. The AL docs cover devenv, devservices, and common issues in depth. The AL server is part of the devinfra-mcp project — see that repo for setup instructions if the server isn't configured yet. The SSE endpoint is configured in .pi/mcp.json (pi) or .mcp.json / .cursor/mcp.json (Claude Code / Cursor).

Step 1: Detect Current State

Before doing anything, assess what's already installed. Run all of these:

# Check OS
uname -s && uname -m

# Check shell
echo $SHELL

# Check if devenv exists
which devenv 2>/dev/null || ls ~/.local/share/sentry-devenv/bin/devenv 2>/dev/null
