nucleus-apple-mcp: Skill for Claude Code

.agents/skills/bolder/SKILL.md

bolder is a skill for Claude Code, Codex from zish-rob-crur/nucleus-apple-mcp. It costs 25 tokens per session (1,621 once invoked), scanned A, a copy of bolder, MIT.

A design-review guide for making visually plain or overly cautious interfaces more distinctive while keeping them usable.

In plain words
What is it for?
Use it to review a website or app, identify safe-looking areas, and increase their visual impact without sacrificing usability.
Why use it?
It helps add visual interest and personality when a design feels generic or forgettable.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is zish-rob-crur/nucleus-apple-mcp's own configuration. It tells Claude Code and Codex how to work on nucleus-apple-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nucleus-apple-mcp configures →

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

bolder 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 11d 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.

Origin

This is a copy

78% identical to bolder — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Increase visual impact and personality in designs that are too safe, generic, or visually underwhelming, creating more engaging and memorable experiences.

MANDATORY PREPARATION

Context Gathering (Do This First)

You cannot do a great job without having necessary context, such as target audience (critical), desired use-cases (critical), brand personality/tone, and everything else that a great human designer would need as well.

Attempt to gather these from the current thread or codebase.

  1. If you don't find exact information and have to infer from existing design and functionality, you MUST STOP and STOP and call the AskUserQuestionTool to clarify. whether you got it right.
  2. Otherwise, if you can't fully infer or your level of confidence is medium or lower, you MUST STOP and call the AskUserQuestionTool to clarify. clarifying questions first to complete your context.

Do NOT proceed until you have answers. Guessing leads to generic AI slop.

Use frontend-design skill

Use the frontend-design skill for design principles and anti-patterns. Do NOT proceed until it has executed and you know all DO's and DON'Ts.


Assess Current State

Analyze what makes the design feel too safe or boring:

  1. Identify weakness sources:

    • Generic choices: System fonts, basic colors, standard layouts
    • Timid scale: Everything is medium-sized with no drama
    • Low contrast: Everything has similar visual weight
    • Static: No motion, no energy, no life
    • Predictable: Standard patterns with no surprises
    • Flat hierarchy: Nothing stands out or commands attention
  2. Understand the context:

    • What's the brand personality? (How far can we push?)
    • What's the purpose? (Marketing can be bolder than financial dashboards)
    • Who's the audience? (What will resonate?)
    • What are the constraints? (Brand guidelines, accessibility, performance)

If any of these are unclear from the codebase, STOP and call the AskUserQuestionTool to clarify.

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.
