Review Design System Compliance
Scan the project's UI code and produce a compliance report covering
design system adherence and AI slop detection.
DESIGN.md Discovery
Find DESIGN.md using this search order:
- Check CLAUDE.md in cwd for a reference to DESIGN.md
- Look for DESIGN.md in cwd
- Search upward from cwd
- Search common locations: project root,
src/, packages/*/
- If not found, tell the user: "No DESIGN.md found. Run
/design-systems:create first."
Input
Optional argument: path to specific files or directory to review.
Default: scan all UI code in the project.
Review Flow
Step 1: Parse Enforceable Rules
Extract from DESIGN.md:
| Source | What to Extract | Use |
|---|
| Palette (Section 2) | All hex values with token names | Detect hardcoded colors outside the set |
| Type Scale (Section 3) | Font families, weights | Detect unauthorized fonts/weights |
| Spacing Scale (Section 4) | All spacing values | Detect off-scale spacing |
| Shadow Definitions (Section 5) | Exact CSS shadow values | Detect non-token shadows |
| Components (Section 6) | Border-radius values | Detect non-token radii |
| Core Prohibitions (Section 1) | Each prohibition as a rule | Custom check per prohibition |
Step 2: Determine Scan Scope
Target file types: *.css, *.scss, *.jsx, *.tsx, *.vue, *.svelte
Exclude patterns:
node_modules/**dist/**, build/**, .next/**, out/**vendor/***.min.css, *.min.js
Use Glob to find files: **/*.{css,scss,jsx,tsx,vue,svelte}
If the user provided a specific path, scope to that path only.
Step 3: Design System Compliance Audit
For each DESIGN.md section, scan the codebase:
Colors (Section 2):
- Grep for hex patterns:
#[0-9a-fA-F]{3,8}
- Also grep for
rgb(, rgba(, hsl(, hsla( color declarations
- Cross-reference each found value against the DESIGN.md palette
- Flag any color not in the token set
- Severity: CRITICAL if the color is explicitly banned (e.g., pure #000000 when prohibited), MODERATE otherwise
Typography (Section 3):
- Grep for
font-family declarations in CSS/SCSS
- Grep for
fontFamily in JSX/TSX (inline styles, styled-components)
- Cross-reference against the DESIGN.md type scale font families
- Flag any font not in the allowed list
- Also grep for
font-weight values and check against allowed weights
- Severity: CRITICAL if a banned font (Inter, Roboto, etc.), MODERATE if just off-system
Spacing (Section 4):
- Grep for
margin, padding, gap with explicit values (not auto or 0)
- Cross-reference values against the DESIGN.md spacing scale
- Flag values not derivable from the scale
- Severity: MODERATE (spacing drift is common and usually non-critical)
Shadows (Section 5):
- Grep for
box-shadow declarations
- Compare each found shadow against the DESIGN.md shadow tokens
- Flag non-matching shadows
- Severity: MODERATE, unless it matches the generic AI shadow (
0 4px 6px rgba(0,0,0,0.1)) which is CRITICAL
Radius (Section 6):
- Grep for
border-radius values
- Cross-reference against DESIGN.md-defined radius tokens
- Flag non-token values
- Severity: MINOR
Core Prohibitions (Section 1):
- For each prohibition, construct a check:
- "No 1px borders" → Grep for
border.*1px solid or border-width: 1px
- "No centered body text" → Grep for
text-align: center in body contexts
- "No pure #000000" → Grep for
#000000 or #000 exact matches
- Other prohibitions: use judgment to construct appropriate grep patterns
- Flag every match
- Severity: CRITICAL (prohibitions are absolute)
Step 4: AI Slop Detection
Independent of DESIGN.md, check for Instant Giveaways. Read the full
checklist from ${CLAUDE_PLUGIN_ROOT}/skills/create/references/anti-slop.md.
Key patterns to grep for:
| Pattern | Grep Target | Severity |
|---|
| Purple/indigo gradients | #667eea, #764ba2, bg-indigo, from-indigo, to-purple | WARNING |
| Banned default fonts | font-family.*Inter[^-], font-family.*Roboto, font-family.*"Open Sans", font-family.*Lato, font-family.*Arial | WARNING |
| Gradient text | -webkit-background-clip: text, background-clip: text | WARNING |
| Generic shadow | box-shadow.*0.*4px.*6px.*rgba\(0.*0.*0.*0\.1\) | WARNING |
| Glassmorphism combo | backdrop-filter.*blur near rgba background near rgba border | WARNING |
| Generic card shadow combo | border-radius.*8px or border-radius.*12px near box-shadow.*rgba\(0.*0.*0.*0\.1\) | WARNING |
| Left border accent | border-left.*4px solid var\(-- | WARNING |
Note: "Three-column icon grid" and "nested cards" are structural patterns
that can't be reliably grep-detected. Use judgment when reading JSX/TSX
components — flag if you notice these patterns during the scan.
Step 5: Generate Report
Output this report format to the terminal:
## Design System Review: [Project/Directory Name]
### Summary
- Compliance: X/7 sections passing
- Violations: N found (C critical, M moderate, I minor)
- AI Slop Markers: N detected
### Section Results
#### Colors [PASS/FAIL]
[List violations or "No violations found."]
#### Typography [PASS/FAIL]
[List violations or "No violations found."]
#### Spacing [PASS/FAIL]
[List violations or "No violations found."]
#### Shadows [PASS/FAIL]
[List violations or "No violations found."]
#### Radius [PASS/FAIL]
[List violations or "No violations found."]
#### Components [PASS/FAIL]
[List violations or "No violations found."]
#### Prohibitions [PASS/FAIL]
[List violations or "No violations found."]
### AI Slop Detection
[List warnings or "No AI slop markers detected."]
### Prohibition Violations
[List critical violations or "All Core Prohibitions respected."]
### Drift Analysis
[If multiple violations cluster in one area, note the pattern.
Example: "Shadow values are the main area of non-compliance —
6 of 8 violations are shadow-related. Consider updating shadow
tokens or refactoring these components."]
Violation format:
- [SEVERITY] path/to/file.ext:LINE — Description of violation
Severity levels:
- CRITICAL: Violates a Core Prohibition or uses a banned anti-slop pattern
- MODERATE: Uses a value outside the token set but not explicitly prohibited
- MINOR: Style inconsistency (e.g., hardcoded value matching a defined token)
- WARNING: AI slop marker detected (not a design system violation per se)
A section PASSES if it has zero CRITICAL and zero MODERATE violations.
MINOR violations alone do not cause a section to fail.
Context
This is the review/audit skill of the design-systems plugin. It checks code against DESIGN.md AND the AI slop reference. The anti-slop reference is at ${CLAUDE_PLUGIN_ROOT}/skills/create/references/anti-slop.md.
