What is the primary goal of the tf:3 skill?

The goal is to create a 'big picture' design, clarify technical choices, and identify uncertainties before implementation to prevent structural mistakes.

What happens after the design phase is complete?

Once finished, the skill prompts you to move to the next stage (/tf:4) to break down the design into actionable tasks.

Does it support existing codebases?

Yes, the skill uses tools like Glob, Grep, and Read to explore your existing codebase and ensure new designs respect established patterns.

Do I need to complete previous steps before using tf:3?

Yes, this skill requires outputs from Step 0 (Problem Definition), Step 1 (Goals), and Step 2 (Requirements) to function correctly.

How does it help with technology selection?

It guides you through a structured discussion comparing chosen technologies against alternatives, documenting the rationale and complexity trade-offs.

Guides architectural planning, technology selection, and risk identification to prevent technical debt before implementation.

The tf:3 skill is a specialized module for Claude Code designed to manage the 'Design' phase of development. It enforces a structured thinking process that transforms requirements into a concrete blueprint by defining system flows, component boundaries, and state ownership. By facilitating technical trade-off discussions and identifying architectural uncertainties early, it ensures developers have a clear roadmap and justified technology choices before writing code, effectively preventing 'understanding debt' in complex projects.
