Design

What it does

When your agent uses it

• Frontend & Design work in your project

Example prompts

• “Use the design skill to generate and maintains a design manifest for visual consistency”
• “/design”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit e41ff1d. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Design loads about 1.6k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 529 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~71

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Generates and maintains a design manifest for visual consistency. In existing projects, reads current styles and documents the design language. In new projects, asks a few questions and generates a starter manifest. The post-edit hook reads the manifest and flags deviations.

# Design Manifest

> Generated: {date}
> Mode: {extracted | generated}
> Source: {tailwind.config.ts, globals.css, etc. | user preferences}

## Colors

### Primary Palette
- primary: {hex} — {usage: buttons, links, accents}
- primary-hover: {hex}
- primary-muted: {hex}

### Neutral Palette
- background: {hex}
- surface: {hex} — {cards, modals, elevated elements}
- border: {hex}
- text-primary: {hex}
- text-secondary: {hex}
- text-muted: {hex}

### Semantic
- success: {hex}
- warning: {hex}
- error: {hex}
- info: {hex}

## Typography

- font-family: {value}
- heading-font: {value, or "same as body"}
- Type scale: {xs, sm, base, lg, xl, 2xl, 3xl — with px/rem values}
- Line heights: {tight, normal, relaxed — with values}
- Font weights used: {list}

## Spacing

- Base unit: {4px / 0.25rem}
- Scale: {1, 2, 3, 4, 6, 8, 12, 16, 24 — in base units}
- Component padding: {standard value}
- Section gap: {standard value}
- Page margin: {standard value}

## Shape

- Border radius: {none, sm, md, lg, full — with values}
- Default radius: {which one is used most}
- Shadow scale: {sm, md, lg — with values}

## Layout

- Max content width: {value}
- Breakpoints: {sm, md, lg, xl — with values}
- Grid/flex preference: {which is used more}
- Spacing rhythm: {consistent gaps between sections}

## Component Patterns

{Only populated in extract mode or after the project has components}
- Button: {padding, radius, font-weight, transition}
- Card: {padding, radius, shadow, border}
- Input: {padding, radius, border-color, focus-ring}

## Anti-Patterns (things to flag)

- Colors not in the palette above
- Font sizes not in the type scale
- Spacing values not in the spacing scale
- Border radius values not matching the shape section
- Hardcoded colors instead of CSS variables or Tailwind classes

---HANDOFF---
- Design manifest: .planning/design-manifest.md
- Mode: {extracted | generated}
- Sources: {files read, or "user preferences"}
- Anti-patterns documented: {count}
- Next: Post-edit hook will flag deviations automatically
- Reversibility: amber — undo with `git checkout .planning/design-manifest.md`
