mpga-frontend-design

mpga-frontend-design is a skill for Claude Code from benrben/MPGA. It costs 21 tokens per session (229 once invoked), scanned A, original, MIT.

Guidance that applies a project's design rules and a chosen visual style to user-interface work without writing the code itself.

In plain words
What is it for?
Use it during UI implementation in React, Vue, Svelte, or plain JavaScript projects to pass design tokens and style direction to the coding step.
Why use it?
It gives developers consistent design constraints while respecting existing design systems and different frontend technologies.

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

mpga-frontend-design 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.

What it actually says

frontend-design

Trigger: Auto-activates during the green-dev phase for UI tasks or when the user explicitly wants frontend design direction before implementation.

Protocol

  1. Detect the current stack:
    • React
    • Vue
    • Svelte
    • vanilla
  2. Load available design tokens from MPGA/design-system/.
  3. Choose one of the aesthetic presets:
    • Clean minimal
    • Bold editorial
    • Soft craft
    • Industrial
    • Custom
  4. Inject the constraints into the green-dev prompt.
  5. Let green-dev implement within those constraints.

Rules

  • Stack-agnostic only. Shape constraints, not framework code.
  • Never override an existing design system. Extend it carefully.
  • This skill is a context injection pattern, not a direct code generator.

Output

  • Aesthetic and token constraints ready for green-dev
  • Stack-aware implementation guidance
  • Clear note when no design-system files exist yet

What this file has done since we first saw it

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.
