sublinkPro: Skill for Claude Code

.agents/skills/theme-check/SKILL.md

theme-check is a skill for Claude Code from ZeroDeng01/sublinkPro. It costs 35 tokens per session (1,323 once invoked), scanned A, original, MIT.

A review checklist for changing frontend colors, surfaces, dialogs, and other parts of a user interface that must work in both light and dark mode.

In plain words
What is it for?
Use it when updating theme settings or shared UI components, then check light and dark modes, desktop and mobile layouts, responsive breakpoints, fullscreen dialogs, and safe-area spacing.
Why use it?
It helps prevent a visual change from looking correct in one theme, screen size, or device but failing in another.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

theme-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Theme Check Skill

Comprehensive checklist for frontend theme adaptation changes.

When to use this skill

Use this skill when:

  • Modifying colors, surfaces, shadows, borders, icons, dialogs, panels, preview cards, overlays, notices, chips, rich text, or status colors
  • Changing theme infrastructure (webs/src/themes/*, webs/src/utils/colorUtils.js)
  • Updating shared sx helpers or common dialog/card/panel styles
  • Working on any UI component that affects light/dark mode presentation

Prerequisites

Before running this checklist:

  1. Read docs/frontend-theme-guidelines.md for complete theme rules
  2. Identify the blast radius: page, module, shared component, or theme infrastructure
  3. Find reference patterns in the codebase (NodePreview*, Chain*, Airport* clusters)

Checklist

1. Mode Coverage

  • Checked both light and dark modes (not just visual validation in current mode)
  • Verified with actual theme toggle, not just screenshots

2. Device Coverage

  • Checked desktop view
  • Checked mobile view
  • Verified responsive breakpoints (useMediaQuery)
  • Tested fullscreen dialogs on mobile
  • Checked safe-area handling

3. Component Structure Coverage

  • Page body
  • Dialogs (Dialog component)
  • Drawers (Drawer component)
  • Popovers (Popover component)
  • Menus (Menu component)
  • Tooltips (Tooltip component)
  • Preview cards
  • Detail panels
  • Footer overlays
  • Empty states
  • Skeletons
  • Notification/overlay entry points

4. Text Hierarchy

  • Primary text (text.primary)
  • Secondary text (text.secondary)
  • Icons
  • Chips
  • Badges
  • Links
  • Code blocks (code, pre)
  • Placeholders
  • Helper text
  • Disabled copy
  • State colors (success/warning/error/info)

5. Interactive States

  • Default state
  • Hover state
  • Active/selected state
  • Disabled state
  • Focus-visible state
  • Expanded/collapsed state

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
