Architecture Foundations
Interviews the technical architect about the foundations a project is built on — the immovable constraints, the shared domain model and which feature owns each field, the interface contracts between features, and the authority model governing who can do what. Runs early, before experience design, and is re-run as specifications accumulate. Deliberately stops short of budgets, mechanisms and build order, which need the experience work first. Use this once the first specifications exist, and again whenever a new specification introduces an entity, a state or an authority. Trigger it when someone wants to capture technical constraints, establish a shared data model, define what each feature owns, agree interface contracts, or work out the guardrails a design has to live within.

From the source SKILL.md
Establish what is already fixed, what the shared things are called, who owns each of them, and who is allowed to do what — so that specifications written weeks apart still describe one system.
What this skill does
Architecture Foundations 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/architecture-foundations/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Architecture Foundations Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 190,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Architecture Foundations skill?
Use Architecture Foundations 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 Architecture Foundations" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Architecture Foundations 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). Skills are auto-discovered at session start. Architecture Foundations is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
/learn/what-is-a-claude-skill/.
