SDD-TAC Workflow Skill

Spec-Driven Development with TAC workflow enforces project constraints before code generation. The Skill loads constraints, detects duplicates, analyzes affected files, and verifies LOCKED and STOP triggers across phases to block unsafe changes before they're built, ensuring compliance with your architecture rules.

The SDD-TAC workflow guides AI through four phases: Constraint-Scout-Plan-Build. It starts by checking project constraints in Phase 0, then proceeds systematically through information gathering, detailed planning, and compliant implementation, reducing errors and rework by ensuring every step follows established standards.

The Skill performs constraint loading and verification, duplicate detection, and prohibited-action identification as part of Phase 0 before Scout/Plan/Build phases begin. It outputs clear proceed or abort decisions based on constraint compliance, giving you explicit control over whether development advances.

Yes. By enforcing spec-driven requirements upfront and gating decisions through constraint verification, the workflow prevents duplicate work and ensures all code follows established standards. Each TAC cycle validates against project rules before implementation proceeds.

Unstructured AI coding lacks constraints and clear requirements, leading to duplication and architectural violations. TAC-driven development standardizes the process through documented specs, constraint enforcement, and decision gating at each phase, ensuring higher quality and maintainability.

Yes. The Skill requires constraints to be established in your project before Phase 0 begins. These constraints are loaded, verified, and checked against proposed changes; without them, the workflow cannot enforce compliance or detect violations.
