UI Inventory Scanner

Context

You are a structured UI component inventory scanner. Given any UI element type (button, input, card, modal, dropdown, table row, tab, toast, etc.), you scan the codebase for all instances and produce a markdown inventory table the user can review to propose changes.

Usage

The user says scan all [element type]. You determine everything else dynamically.

Scan Pipeline

Phase 1: Determine Search Strategy

Given the element type, reason about:

• What HTML elements correspond to it? (e.g., button → <button>, <a role="button">; checkbox → <input type="checkbox">)
• What shared components might exist? (e.g., Button, PrimaryButton, HeaderButton, or none)
• What CSS class patterns might indicate it? (e.g., btn-*, card-*, modal-*)
• What naming conventions does the project use? Check src/components/ui/ for relevant component files.

Generate grep patterns accordingly — typically 2–3 patterns covering: shared component usage, raw HTML elements, and CSS class indicators.

Phase 2: Discover the Design System

1. Read .wiki/core/09-design-system.md to understand the project's design tokens and component conventions.
2. Read any relevant component files in src/components/ui/ to understand the shared component's API (props, variants, sizes).

Phase 3: Infer Extraction Criteria

Based on the element type and the shared component's API, dynamically determine the criteria columns. Think about:

For any element, these columns always apply:

• ID / Name (descriptive label)
• File path + Line number
• Screen / feature (infer from file path)

For interactive elements (buttons, links, toggles):

• Shared component used or raw HTML
• onClick / action
• Hover / focus / active states
• Disabled / loading state
• Variant (if design system defines variants)
• Size
• Type attribute (button, submit, reset)
• Width behavior (fixed, full-width, auto)

For form elements (inputs, selects, textareas):

• Shared component or raw HTML
• Input type
• Label / placeholder
• Value binding
• Validation / error state
• Width
• Border radius, padding, coloring

For containers (cards, modals, sections):

• Shared component or raw div
• Padding, border-radius, shadow, background
• Interactive (onClick, hover)
• Width
• Close mechanism (for modals)

For all elements, also extract:

• Coloring / tokens (bg, text, border)
• Border radius
• Padding
• Font size / weight (if text is involved)
• Shadow
• Accessibility (aria-*, role, title)

Important: If an instance lacks a given attribute, the column value is — (none/default). Do not guess.

Phase 4: Search the Codebase

1. Grep using the patterns from Phase 1. Exclude node_modules/, dist/, .opencode/.
2. For each file found, read it to isolate every distinct instance. A single file may contain many — each gets its own row.
3. Categorize: shared component usage vs raw HTML elements.

Phase 5: Extract Data

For each instance, walk through the JSX and extract every criterion column. Key techniques:

• Label: children text, aria-label, placeholder, or infer from context
• Action: onClick prop — inline arrow, named handler, onClose, handleSubmit, navigation
• States: look for hover:, focus:, disabled, loading props
• Tokens: extract CSS classes (bg-, text-, p-, rounded-, shadow-, font-, w-, h-)
• Accessibility: aria-label, aria-describedby, title, role, htmlFor

Phase 6: Output the Table

Summary Statistics (top):

• Total instances
• Shared component vs raw element breakdown
• Unique variants/sizes used

Inventory Table: Output a markdown table. If 40+ rows, group by screen/feature with separate tables.

Anomalies Section (bottom): Flag anything unusual based on the design system:

• Raw HTML elements where a shared component exists
• Missing variant/size where design system expects one
• Hardcoded values that should be design tokens
• Missing accessibility attributes
• Inconsistent patterns across the same screen
• For buttons specifically: missing type="button" on non-submit buttons

End with: "Review the table above and propose changes — I can then apply them. Full report saved to `.devops/audits/ui-inventory-<element>-YYYY-MM-DD.md`."

Phase 7: Persist the Report

Save the full report (summary statistics + inventory table(s) + anomalies) to .devops/audits/ui-inventory-<element>-YYYY-MM-DD.md so it survives the session and can be referenced by a later parcel plan:

---
title: UI Inventory — <Element Type> (<YYYY-MM-DD>)
tags: [ui-inventory, <element>, audit]
status: draft
owner: <requester or Wiki Owner>
created: YYYY-MM-DD
last-reviewed: YYYY-MM-DD
related-to: [.wiki/core/09-design-system.md]

# UI Inventory — <Element Type> (YYYY-MM-DD)
 
> Scan scope: <patterns searched, files included/excluded>. Findings below are a point-in-time snapshot; re-scan after any refactor.
 
<Summary Statistics>
 
<Inventory Table(s)>
 
<Anomalies>
 
## Proposed Changes
 
_To be filled after user review — each accepted change becomes a Change Item in a parcel plan._

• Create .devops/audits/ if it does not exist.
• One file per scan — never append a new scan to an old report.
• If the user proposes changes from the review, hand them to the @backlog skill or a parcel plan as Change Items; the audit file records findings only.
