A design document package is a structured set of layered artifacts clarifying project intent, logical architecture, milestone sequencing, and BDD validation before implementation begins. It ensures traceable execution for non-trivial features.

You create an implementation plan by structuring milestone-based execution sequencing alongside behavior-first test preparation. This generates separate documents for structural layout planning and BDD-oriented validation design to guide disciplined coding.

You need a C4-style logical architecture layout when planning non-trivial features requiring clear structural design and traceable intent before coding. It articulates layered logic design to support disciplined review and approval.

Yes, this approach supports behavior-first test preparation by generating BDD-oriented validation design as a distinct layer. It integrates test strategy directly into the milestone-based execution plan before implementation starts.

The best way to frame project intent is to define the north star, core tenets, and measurable success criteria upfront. This transforms vague feature requests into a structured design document with traceable architecture.

Yes, you can use this for non-trivial feature planning without external dependencies. It generates a complete design package including logic design, structural layout, and milestone sequencing entirely from your traceable project intent.
