Spec Driven Development (SDD) FAQs

Question 1

Does the sdd skill help with task management?

Accepted Answer

Absolutely. Part of the design phase includes a mandatory task breakdown that groups implementation steps by dependencies, each linked to specific requirements and test scenarios.

Question 2

Can I use the sdd skill with existing projects?

Accepted Answer

Yes. The workflow includes a mandatory exploration phase where Claude reads your existing codebase and project guidelines to ensure new designs remain consistent with your established patterns.

Question 3

Where does the sdd skill store documentation?

Accepted Answer

All SDD artifacts, including feature specifications, design documents, and project guidelines, are stored in a standardized `.sdd/` directory at the root of your repository.

Question 4

How does this skill handle requirement traceability?

Accepted Answer

The skill uses specific tags like `[feature:FR-XXX]` for functional requirements in implementation code and `[feature:TS-XX]` for test scenarios, allowing you to trace any line of code back to its original requirement.

Question 5

What is Spec Driven Development (SDD)?

Accepted Answer

SDD is a development methodology where detailed specifications and architectural designs are completed and validated before any implementation code is written, ensuring all requirements are testable and accounted for.
