What problem does it solve?
Coding without clear, validated requirements leads to misalignment between developers and stakeholders, wasted effort on incorrect feature builds, and costly rework cycles that delay project delivery.
Core Features & Use Cases
- Gated 4-phase workflow: Enforces Specify → Plan → Tasks → Implement progression with mandatory human review at each stage to catch misalignment and incorrect assumptions early.
- Structured spec template: Guides creation of comprehensive, version-controlled specs covering objective, tech stack, commands, project structure, code style, testing strategy, operational boundaries, and testable success criteria.
- Adaptive guardrails: Includes rebuttals to common rationalizations for skipping specs, red flag warnings, and processes to update specs as requirements evolve to keep them aligned with project reality.
- Use cases: Ideal for new project builds, feature development, ambiguous requirement scenarios, multi-file changes, and architectural decisions where clear requirements are critical to success.
Quick Start
Use the spec-driven-development skill to create a validated, human-reviewed specification for your new payment processing feature before writing any implementation code.
