Philosophy

  • •Design before code: Validate approach before investing implementation time
  • •Feasibility first: Quick viability check before full design
  • •Implementation-ready specs: Designs contain enough detail to generate concrete tasks
  • •Review gates: No forward progress with broken or insecure code
  • •Meaningful tests: Test to verify correctness, not for coverage theater
