Coder Hahomelabs

Coder Workspace Environment (hahomelabs.com)

Context for projects running in this Coder workspace environment at hahomelabs.com.

Environment

You are running in a Coder development workspace:

Available Tools

The following tools are pre-installed and available in this workspace:

Service URLs

Services use this URL pattern:

https://<service>--<workspace-name>--<username>.coder.hahomelabs.com

IMPORTANT: Always use full URLs. Do NOT use localhost: URLs as they cause issues with remote services, authentication, cookies, and cross-origin requests.

Optional Features (Enabled at Workspace Creation)

PostgreSQL (CloudNativePG)

When enabled, these environment variables are available:

POSTGRES_HOST     # <workspace-full-name>-db-rw

LLM Gateway

AI requests route through LiteLLM proxy with budget controls:

# Environment variables (ask user before accessing)
OPENAI_BASE_URL      # https://llm-gateway.hahomelabs.com/v1
LITELLM_BASE_URL     # https://llm-gateway.hahomelabs.com
ANTHROPIC_AUTH_TOKEN # Per-user API key (development)
LITELLM_APP_API_KEY  # Per-user API key (applications)

Model mapping:

• Haiku → "small" (fast, low cost)
• Sonnet → "medium" (balanced)
• Opus → "large" (max capability)

Package Managers

System packages

sudo apt-get update
sudo apt-get install <package>

Node.js

Check lockfile to determine which to use:

• pnpm-lock.yaml → Use pnpm
• yarn.lock → Use yarn
• package-lock.json → Use npm
• bun.lockb → Use bun

Background Services

PM2 (Node.js processes)

pm2 status          # Check status
pm2 logs            # View all logs
pm2 logs <app>      # View app logs
pm2 logs --lines 50 --nostream  # View recent log entries
pm2 restart <app>   # Restart app

Docker

docker ps           # List containers
docker logs <container>
docker logs -f <container>  # Follow logs

Workspace Scripts

Scripts are executed automatically by the Coder agent. Use them for:

• Starting development servers with PM2
• Running database migrations
• Setting up environment-specific configurations
• Graceful shutdown of services

Note: Startup script runs with 60-second timeout, then backgrounds if still running.

Platform-Specific Considerations

Docker Usage

• Docker commands work normally (this is not Docker Desktop)
• No special port mapping or host configurations needed
• Docker-in-Docker means containers run inside the workspace environment

File Paths

• Use standard Linux paths (not Windows or macOS formats)
• Relative paths for project files: src/components/Header.tsx
• Absolute paths for system files: /usr/local/bin/tool

Hardware Optimizations

• Target x86_64 architecture for any hardware-specific optimizations
• Do NOT use ARM/Apple Silicon-specific flags or binaries
• Modern Intel/AMD processor features are available

Environment Variables

CRITICAL: Before using or changing ANY environment variable, you MUST:

1. Ask the user for permission - "May I check the environment variables?" or "May I use/change the X environment variable?"
2. Explain what you need - Describe which variable(s) you need to access and why
3. Wait for explicit approval - Do not proceed without user consent

To check available environment variables:

env | grep -i <pattern>    # Search for specific variables
env                        # List all environment variables
printenv                   # Alternative way to list all
echo $VAR_NAME             # Check specific variable

Never modify environment variables without explicit user permission, as they may affect:

• API authentication and routing
• Service connections
• Model selection behavior
• Workspace functionality

Network Services

• Services run on standard Linux ports
• No macOS/Windows port conflicts to consider
• Internal cluster networking with port forwarding for external access

Workspace Cloning

• PostgreSQL cloning: Restores from source workspace backup
• S3 cloning: Syncs data from source workspace bucket
• Restriction: Can only clone from own workspaces (same user)
• Limitation: Source workspace name cannot contain hyphens

GitHub CLI

GitHub CLI (gh) is pre-configured with automatic OAuth token refresh. The token refreshes automatically via a wrapper function in .bashrc.

Gotchas

1. File paths: Use standard Linux paths (/home/coder/project)
2. Architecture: x86_64 only (no ARM binaries)
3. Environment variables: Ask user before accessing
4. Service URLs: Use full URLs, not localhost
5. Disk space: Home directory is persistent, size configurable
6. Workspace cloning: Source workspaces with hyphens in name cannot be used
7. Database: PostgreSQL database name is always app, user is always app

Response Guidelines

• Provide clear, concise, and accurate responses
• Consider the context of the workspace and the user's current task
