  • Claude Opus 4.1 for complex planning (complexity > 8)
  • Extended thinking support (off by default, 5000ms budget)
  • Intelligent model routing based on task complexity

Security

  • Secrets detection and prevention
  • PII detection with masking
  • Security audit logging
  • OAuth token management
  • HTTPS enforcement
  • Certificate validation
  • SOC2, GDPR, HIPAA compliance support

Documentation

  • Comprehensive README with badges and sections
  • Installation guide with 3 installation methods
  • Quick start guide with example workflows
  • Contributing guidelines
  • License (MIT)
  • Example feature development workflow (72-minute full cycle)
  • GitHub issue templates (bug report, feature request)
  • Pull request template

Configuration Files

  • .claude/CLAUDE.md - Main configuration
  • .claude/policies/permissions.json - Permission framework
  • .claude/policies/security.json - Security policies
  • .gitignore - Ignore patterns for state files

Success Metrics

  • 80%+ test coverage
  • < 200ms API response times
  • Zero critical security issues
  • 90%+ documentation completeness
  • < 1% production error rate
  • 10x faster specification-to-implementation
  • 5x reduction in context switches

Philosophy

  • Activity-Based, Not Role-Based: Agents selected by what they DO
  • Parallel by Default: Multiple agents working simultaneously
  • Spec-Driven Development: Comprehensive specs before code
  • Continuous Validation: Phase gates ensure quality
  • Progressive Enhancement: Iterative improvement cycles
  • Knowledge Capture: Document patterns and learnings

Motto

"Ship faster. Ship better. Ship with The Agentic Startup."
