extract: Design & UI for AI Agents | OpenAgentSkill

Overview

Refactoring pass — extracts repeated Tailwind class combos and markup into components, and lifts magic values into design tokens. Use when the codebase has obvious duplication, hardcoded hex values or pixel sizes, or when the user says \"clean this up\" / \"extract components\" / \"tokenize styles\". Invoke when the user asks for extract on their UI, or mentions 'extract' alongside design / UI / frontend work.

Source documentation, not instructions for this website. Review permissions before running any commands.

Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.

Extract reusable pieces from $ARGUMENTS. Load the ui-craft skill.

Step 1 — Scan the target for extraction candidates:

Repeated Tailwind class combos — any class string that appears ≥3 times becomes a component (or a cva/tv variant if the project uses one — check first).
Magic values — hex colors, pixel sizes, shadow definitions, font sizes, z-index values appearing in literal form. Lift into CSS variables or theme.extend.
Repeated markup — blocks that differ only by text/props collapse into a single component with props.

Step 2 — Match the project's conventions, don't impose new ones:

Naming — look at neighboring components. PascalCase file? kebab-case file? Named export vs default export? Match exactly.
Location — check components/ui/, ui/, primitives/, src/components/ before creating a new directory. Reuse.
Tokens — respect existing CSS variable naming (--color-*, --space-*, --font-*, --radius-*). Don't introduce a parallel system.

Step 3 — Anti-Slop Test on every new component (from SKILL.md):

Component name must be domain-specific, not generic. MetricCard / PricingTier / InviteRow beats Card / Box / Item.
If the component is generic ("a card with a title and description"), ask yourself whether it should instead be an inline composition — premature abstraction is worse than repetition.

Step 4 — Update every call-site. No half-migrations.

Knob-agnostic — DRY is not tunable.

References to read: references/layout.md (composition patterns), references/typography.md and references/color.md (token naming), plus the project's existing component library (scan before writing).

Output:

The new component file(s) + any token additions.
A table showing every call-site update:

File	Before	After

A one-line delta: "Extracted N components, M tokens. Call-sites updated: X."

Next step: /tokens — lift the values you just centralized into the token spine (rung 2).

**Context:** this sub-skill is one lens of the broader `ui-craft` skill. If the `ui-craft` skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.

Extract reusable pieces from `$ARGUMENTS`. Load the `ui-craft` skill.

**Step 1 — Scan the target for extraction candidates:**

- **Repeated Tailwind class combos** — any class string that appears ≥3 times becomes a component (or a `cva`/`tv` variant if the project uses one — check first).
- **Magic values** — hex colors, pixel sizes, shadow definitions, font sizes, z-index values appearing in literal form. Lift into CSS variables or `theme.extend`.
- **Repeated markup** — blocks that differ only by text/props collapse into a single component with props.

**Step 2 — Match the project's conventions, don't impose new ones:**

- **Naming** — look at neighboring components. PascalCase file? kebab-case file? Named export vs default export? Match exactly.
- **Location** — check `components/ui/`, `ui/`, `primitives/`, `src/components/` before creating a new directory. Reuse.
- **Tokens** — respect existing CSS variable naming (`--color-*`, `--space-*`, `--font-*`, `--radius-*`). Don't introduce a parallel system.

**Step 3 — Anti-Slop Test on every new component** (from SKILL.md):

- Component name must be domain-specific, not generic. `MetricCard` / `PricingTier` / `InviteRow` beats `Card` / `Box` / `Item`.
- If the component is generic ("a card with a title and description"), ask yourself whether it should instead be an inline composition — premature abstraction is worse than repetition.

**Step 4 — Update every call-site.** No half-migrations.

**Knob-agnostic** — DRY is not tunable.

**References to read**: `references/layout.md` (composition patterns), `references/typography.md` and `references/color.md` (token naming), plus the project's existing component library (scan before writing).

**Output**:
1. The new component file(s) + any token additions.
2. A table showing every call-site update:

| File | Before | After |
| --- | --- | --- |

3. A one-line delta: "Extracted N components, M tokens. Call-sites updated: X."

**Next step:** `/tokens` — lift the values you just centralized into the token spine (rung 2).

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
