For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.\n\n## ⚡ Get Started\n\n### 1.

## Claude's Role
Read `.specify/memory/constitution.md` first. It is the authoritative source of truth for this project. Everything in it is non-negotiable.

## SpecKit Commands
- `/speckit.specify` — generate spec
- `/speckit.plan` — generate plan
- `/speckit.tasks` — generate task list
- `/speckit.implement` — execute plan

## On Ambiguity
If a spec is missing, incomplete, or conflicts with the constitution — stop and ask. Do not infer. Do not proceed.
