Design Codebase

Category: Product  ·  Sub-category: design-system-ui  ·  Last updated:
Use when the user asks to make or compare a codebase architecture decision involving module boundaries, ownership, interfaces, seams, adapters, domain language, or a throwaway prototype that answers a design question. Also use during implementation only when a non-obvious architecture, ownership, interface, or dependency-boundary decision blocks the next safe edit; a testability concern qualifies only when it demonstrates that kind of boundary pressure. Do not use for ordinary code explanation, straightforward implementation, general test design, flaky tests, mocks, regression coverage, or implementation of an already selected design.

From the source SKILL.md

Use architecture language to improve leverage, locality, and testability without turning ordinary implementation into a design ceremony.

What this skill does

Design Codebase is a community-contributed Claude Code skill in the design-system-ui sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/design-codebase/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks to make or compare a codebase architecture decision involving module boundaries, ownership, interfaces, seams, adapters, domain language, or a throwaway prototype that answers a design question. Also use during implementation only when a non-obvious architecture, ownership, interface, or dependency-boundary decision blocks the next safe edit; a testability concern qualifies only when it demonstrates that kind of boundary pressure.

Who uses this skill

The Design Codebase Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 168,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

What does the Design Codebase skill do?
Use when the user asks to make or compare a codebase architecture decision involving module boundaries, ownership, interfaces, seams, adapters, domain language, or a throwaway prototype that answers a design question. Also use during implementation only when a non-obvious architecture, ownership, interface, or dependency-boundary decision blocks the next safe edit; a testability concern qualifies only when it demonstrates that kind of boundary pressure. Do not use for ordinary code explanation, straightforward implementation, general test design, flaky tests, mocks, regression coverage, or implementation of an already selected design.
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 Design Codebase skill?
Use Design Codebase when your Claude Code task falls under the Product category — specifically in the design system ui 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 Design Codebase" or describe the task and let Claude pick). Browse related skills at /category/product/.
What is a Claude Code skill and how does the Design Codebase 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. Design Codebase is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Product category.
