PixelPilot uiux-migration.instructions.md

A migration guide for replacing hardcoded CSS values and basic browser controls with a shared design-token system. Design tokens are named values for things such as spacing, colours, and font sizes.

In plain words
What is it for?
Scanning CSS and JSX, mapping pixel values and colours to tokens, finding native controls that need replacement, and producing suggested before-and-after changes.
Why use it?
It helps an older interface follow one consistent visual system instead of scattering raw values throughout the code.

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

PixelPilot uiux-migration.instructions.md 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 2d 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.

UI/UX Migration Skill

Convert legacy CSS to design tokens. Scan for hardcoded values and native UI elements that must be replaced with custom token-styled components.


MIGRATION OVERVIEW

This skill helps convert existing codebases to the OpenCode UI/UX 2026 design system by:

  1. Scanning for hardcoded values (px, hex colors, raw radii)
  2. Detecting native browser UI elements that need replacement
  3. Providing token mappings and automated fix suggestions
  4. Generating diff output showing before/after

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.
