om-scogo gstack Workflow Assistant
Skill by ara.so — Daily 2026 Skills collection
Transform Claude Code from a generic assistant into a team of specialists you can summon on demand. Eight opinionated workflow skills that act as CEO, Engineering Manager, Release Manager, and QA Engineer with slash commands for planning, review, shipping, and testing.
What It Does
gstack provides specialized AI personas and workflows:
- CEO Review: Rethink problems and find the 10-star product hiding in requests
- Engineering Planning: Lock in architecture, data flow, and edge cases
- Code Review: Paranoid staff engineer-level review that catches production bugs
- Release Management: One-command shipping with tests and PR creation
- QA Testing: Automated browser testing with screenshots and systematic coverage
- Browser Automation: Give AI eyes to click through your app and catch breakage
- Session Management: Import real browser cookies for authenticated testing
- Team Retrospectives: Engineering manager-style retros with per-person insights

Core Commands
Planning Workflows
CEO Product Review
// Start with feature description, then review strategy
You: I want to add seller photo upload to the listing app
You: /plan-ceo-review
// AI responds as CEO: challenges assumptions, finds bigger opportunity
// "Photo upload" → "AI-powered listing creation from photos"
Engineering Architecture Review
You: /plan-eng-review
// AI responds as tech lead:
// - Architecture diagrams
// - State machines
// - Async job boundaries
// - Failure modes
// - Test matrices
Code Quality Workflows
Thorough Code Review
You: /review
// Paranoid staff engineer review:
// - Race conditions
// - Trust boundaries
// - Missing error handling
// - Production failure modes
One-Command Shipping
You: /ship
// Automated release process:
// 1. Sync main branch
// 2. Run test suite
// 3. Resolve review comments
// 4. Push branch
// 5. Open pull request
QA and Testing Workflows
Browser Automation
You: /browse https://myapp.com
// AI navigates your app:
// - Takes screenshots
// - Clicks through workflows
// - Identifies breakage
// - Tests responsive design
Systematic QA Testing
You: /qa
// Branch-aware testing:
// - Analyzes git diff
// - Identifies affected pages
// - Tests localhost:3000
// - Full exploration mode
// - Regression testing
You: /qa https://staging.myapp.com --quick
// Quick smoke test: 5 pages in 30 seconds
Session Management
You: /setup-browser-cookies staging.myapp.com
// Imports cookies from real browser (Chrome, Arc, Brave, Edge)
// Enables testing authenticated pages without manual login
Team Workflows
Engineering Retrospectives
You: /retro
// Engineering manager-style retro:
// - Analyzes git history
// - Per-person contributions
// - Growth opportunities
// - Team dynamics
// - Saves to .context/retros/
Configuration
Browser Settings
gstack creates isolated browser instances in .gstack/ directory:
// Automatic browser configuration
{
userDataDir: '.gstack/browser-data',
headless: false, // for debugging
viewport: { width: 1280, height: 720 },
timeout: 30000
}

Integration Patterns
Multi-Session Workflow
Use Conductor for parallel sessions:
// Session 1: Feature development
You: /plan-ceo-review
You: /plan-eng-review
// [implement feature]
// Session 2: Code review
You: /review
// [fix issues]
// Session 3: QA testing
You: /qa --full
// Session 4: Release
You: /ship
CI/CD Integration
# .github/workflows/gstack-qa.yml
name: gstack QA
on: [pull_request]
jobs:
qa:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- run: cd .claude/skills/gstack && ./setup
- run: echo "/qa --regression" | claude-code
Team Onboarding
# Add to team docs
## Development Workflow
1. `/plan-ceo-review` - Validate product direction
2. `/plan-eng-review` - Lock architecture
3. Implement feature
4. `/review` - Paranoid code review
5. `/qa` - Test branch thoroughly
6. `/ship` - One-command release
7. `/qa staging.app.com` - Staging verification
Advanced Usage
Custom QA Scenarios
// Feature-specific testing
You: /qa --focus=checkout-flow
You: /qa --mobile-only
You: /qa --accessibility
// Performance testing
You: /browse https://app.com
// Then: "Run lighthouse audit on this page"
Cross-Browser Testing
// Test in multiple browsers
You: /setup-browser-cookies app.com
You: /browse app.com --browser=chrome
// [switch session]
You: /browse app.com --browser=firefox
Regression Testing
// Before major changes
You: /qa --baseline
// [make changes]
You: /qa --compare-baseline
// AI identifies visual/functional regressions
Troubleshooting
Binary Issues
# Rebuild browser automation binary
cd .claude/skills/gstack
rm -rf browse/dist
./setup
Permission Errors
# Fix executable permissions
cd .claude/skills/gstack
chmod +x setup browse/dist/browse
Missing Dependencies
# Reinstall Node dependencies
cd .claude/skills/gstack
rm -rf node_modules
bun install
Browser Automation Failures
// Debug browser issues
You: /browse --debug
// Runs browser in non-headless mode for inspection
// Clear browser data
rm -rf .gstack/browser-data
Skill Registration Issues
// Re-register skills
cd .claude/skills/gstack
./setup
// Verify skills are available
You: /plan-ceo-review --help
The skills work by providing specialized prompts and browser automation tools that transform Claude Code into domain experts. Each workflow enforces specific cognitive modes - CEO strategic thinking, engineering rigor, paranoid review, or systematic testing - instead of generic assistance.
