Spec Driven System Architecture

Category: Engineering  ·  Sub-category: architecture  ·  Last updated:
type:integration
Produces the System Architecture Document and the constitutional context files for a project through a spec-driven workflow with structural anti-skip enforcement. This skill is the macro/constitutional architect phase: it consumes the Project Management plan, locks the technology stack, defines system boundaries and integration topology, and emits the immutable context files plus ADRs. Use when the user runs /create-system-architecture or after the PM (/ideate) phase completes. Do NOT use for per-epic technical design (use spec-driven-solution-architecture).

From the source SKILL.md

Translate the Project Management plan into the project constitution — the 6 immutable context files, their .ai.md companions, test-plan.ai.yaml, the architecturally significant ADRs — and a System Architecture Document describing system boundaries, integration topology, tech-stack rationale, system NFRs, and deployment architecture. Governed by ADR-067.

What this skill does

Spec Driven System Architecture is a community-contributed Claude Code skill in the architecture sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/spec-driven-system-architecture/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user runs /create-system-architecture or after the PM (/ideate) phase completes. Do NOT use for per-epic technical design (use spec-driven-solution-architecture).

Who uses this skill

When should I use the Spec Driven System Architecture skill?
Use Spec Driven System Architecture when your Claude Code task falls under the Engineering category — specifically in the architecture area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Spec Driven System Architecture" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Spec Driven System Architecture skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools).
