Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Senior Fullstack

Guide fullstack development using modern tools and established patterns.

Core Workflow

1. Scaffold a Project

Run the fullstack scaffolder to generate project structure:

python scripts/fullstack_scaffolder.py  [options]

Use the project scaffolder for analysis and optimization:

python scripts/project_scaffolder.py  [--verbose]

2. Analyze Code Quality

Run the analyzer to detect issues and get recommendations:

python scripts/code_quality_analyzer.py [--analyze]

3. Apply Architecture Patterns

Consult reference docs before implementing:

  • references/tech_stack_guide.md -- patterns, examples, anti-patterns
  • references/architecture_patterns.md -- workflows, optimization, troubleshooting
  • references/development_workflows.md -- integrations, security, scalability

Tech Stack

| Layer | Technologies | |-------|-------------| | Languages | TypeScript, JavaScript, Python, Go | | Frontend | React, Next.js, React Native | | Backend | Node.js, Express, GraphQL, REST | | Database | PostgreSQL, Prisma, Supabase | | DevOps | Docker, Kubernetes, Terraform, GitHub Actions | | Cloud | AWS, GCP, Azure |

Key Principles

  • Immutability: Return new objects, never mutate ({ ...obj, key: value })
  • Validation: Use Zod for input validation, parameterized queries for SQL
  • Structure: Functions under 50 lines, files under 800 lines, nesting under 4 levels
  • Security: No hardcoded secrets, server-side API calls only, proper auth checks

Common Commands

npm run dev          # Start dev server
npm run build        # Production build
npm test             # Run tests
npm run lint         # Lint code
docker build -t app:latest .   # Build container

Error Handling

  • If scaffolder fails: verify Python 3.8+ is installed and scripts/ directory exists
  • If quality analyzer reports issues: fix CRITICAL/HIGH first, then MEDIUM
  • If build fails after scaffolding: check package.json dependencies and .env configuration
  • Always run npm run type-check before committing changes
