In plain words
What is it for?
Understanding the repository structure, architecture, plugin files, skills, and development workflows for Fluxwing Skills.
Why use it?
It gives an agent the background needed to work in the repository without guessing what its files and terms mean. It also separates the tool from the format it produces.

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

fluxwing-skills CLAUDE.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 10d 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.

Project Overview

Fluxwing Skills is a Claude Code skills system that enables AI-native UX design using the uxscii standard. This repository contains skills that allow Claude to create, validate, and compose UI designs through natural language using ASCII art and structured JSON metadata.

Key Distinction:

  • Fluxwing = The AI bot/agent system (the tool)
  • uxscii = The standard format (the language)
  • Think: Figma vs HTML/CSS

Development Location: This repository (fluxwing-skills) is the development location for six Claude Code skills packaged as a Claude Code plugin.

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.
