Dev Environment Manager

When to Use This Skill

Use this skill when:

• Setting up or resetting local development environment
• Running health checks on databases
• Validating environment before deployment
• Syncing production data to local or staging

Quick Commands (Recommended)

The easiest way to reset and sync your local database:

# Reset local DB + sync from STAGING (default)
pnpm supabase:web:reset

# Reset local DB + sync from PRODUCTION
pnpm supabase:web:reset --prod

# Reset local DB only (no data sync)
pnpm supabase:reset:no-sync

These commands:

1. Apply all migrations (reset schema)
2. Sync data from staging/production
3. Include auth.users for login testing

Login locally with any synced user email + password password

Full Sync Workflow: Production → Staging → Local

For a complete refresh of all environments:

# Step 1: Sync production data to staging
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh --confirm --yes

# Step 2: Reset local and sync from staging
pnpm supabase:web:reset

This ensures staging mirrors production, then local mirrors staging.

Data Sync Details

Safety Guarantees

All sync scripts have multiple safety layers to prevent accidental production writes:

1. Read-only production connection - Scripts only construct READ connections to production
2. Explicit confirmation required - Must pass --confirm flag AND type confirmation text
3. Target verification - Scripts verify the target database before writing
4. Clear visual warnings - Red warning banners before any destructive operation

Sync Production → Staging

# Preview what will happen (safe, no changes)
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh

# Execute the sync (requires confirmation)
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh --confirm

# Skip interactive prompt
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh --confirm --yes

What it does:

1. READ all public + auth schema data from production
2. ERASE all data in staging
3. COPY production data to staging
4. Verify row counts match

Production is NEVER modified.

Sync to Local (Staging or Production)

# Sync from STAGING (default)
pnpm supabase:web:reset

# Sync from PRODUCTION
pnpm supabase:web:reset --prod

# Or use scripts directly:
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-local.sh --confirm --yes

What it does:

1. Reset local database (apply all migrations)
2. READ all data from staging/production
3. COPY data to local (includes auth.users)
4. Verify row counts match

Credentials

Scripts automatically load credentials from:

1. .env.local (preferred)
2. 1Password (fallback, then cached to .env.local)

Required environment variables:

• SUPABASE_DB_PASSWORD_PROD - Production database password
• SUPABASE_DB_PASSWORD_STAGING - Staging database password

Quick Start Examples

Fresh Local Setup (Most Common)

# Start local Supabase + reset with staging data
pnpm supabase:web:start
pnpm supabase:web:reset

Refresh All Environments

# Full sync: prod → staging → local
./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh --confirm --yes
pnpm supabase:web:reset

Reset Without Sync

# Fresh migrations, no external data
pnpm supabase:reset:no-sync

Pre-Deployment

# Run all checks before deploying
./.claude/skills/dev-environment-manager/scripts/pre-deployment-checks.sh

Database References

Troubleshooting

"Local Supabase is not running"

cd apps/web && pnpm supabase start

"Failed to get password from 1Password"

# Authenticate with 1Password
op signin

# Or set credentials manually in apps/web/.env.local:
SUPABASE_DB_PASSWORD_PROD="your-password"
SUPABASE_DB_PASSWORD_STAGING="your-password"

"Connection timeout"

• Ensure you're using aws-1-eu-central-1.pooler.supabase.com (not aws-0)
• Check network/VPN connection
• Verify credentials are correct

Resetting Remote Database (Staging)

WARNING: supabase db reset has --local=true by default!

# WRONG - This resets BOTH local AND staging!
supabase db reset --db-url "postgresql://staging..."

# CORRECT - Only reset staging
supabase db reset --db-url "postgresql://staging..." --local=false

For staging schema reset, prefer using the sync script which handles this correctly:

./.claude/skills/dev-environment-manager/scripts/sync-prod-to-staging.sh --confirm --yes

Vercel Environment Variables

Fix Trailing Newlines

Vercel env vars sometimes get trailing \n characters that break API connections.

# Fix production only (interactive)
./.claude/skills/dev-environment-manager/scripts/fix-production-env-vars.sh

# Fix production only (non-interactive)
./.claude/skills/dev-environment-manager/scripts/fix-production-env-vars.sh --yes

# Fix preview/staging only
./.claude/skills/dev-environment-manager/scripts/fix-production-env-vars.sh --env preview --yes

# Fix ALL environments (preview + production)
./.claude/skills/dev-environment-manager/scripts/fix-production-env-vars.sh --env all --yes

What it does:

1. Pulls current env vars from Vercel
2. Finds vars with trailing \n characters
3. Removes and re-adds them using echo -n (no trailing newline)
4. Verifies the fix worked
