SDD-TAC Development Workflow

About

Streamline complex software development tasks using the Spec-Driven Development (SDD) and Tactical Agentic Coding (TAC) methodology. This skill guides developers through a disciplined four-phase approach: Phase 0 for constraint verification, Scout for thorough codebase reconnaissance, Plan for architectural design, and Build for systematic execution. It is particularly effective for managing tasks involving three or more files, ensuring that new implementations respect existing patterns, avoid duplication through mandatory stakeholder consultation, and adhere to critical security and project constraints.

Key Features

• Phase 0 constraint checking to prevent unauthorized or dangerous operations
• Automated task complexity assessment based on affected file counts
• Mandatory 'Extend vs. Create' decision points using interactive user prompts
• 0 GitHub stars
• Scout-Plan-Build workflow for systematic multi-file implementation
• Integration with domain-specific guidance for auth, database, and API work

Use Cases

• Refactoring core logic that spans across multiple files and directories
• Implementing complex new features requiring architectural planning and reconnaissance
• Safely fixing bugs in mission-critical files while adhering to project-specific constraints
