create-style

create-style is a command for coding agents from MadAppGang/magus. It costs 45 tokens per session (6,011 once invoked), scanned A, a copy of create-style, MIT.

An interactive wizard for creating and updating a project's UI design guide and its visual reference images.

In plain words
What is it for?
Use it to create or update a design guide, capture references, add or remove reference images, and list the stored references.
Why use it?
It organizes design decisions such as colors, typography, spacing, and component rules in one project file without changing application source 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

create-style 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 5d 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

100% identical to create-style — 22 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.

  - Use Tasks to track wizard progress
  - Use Bash for file operations in `.claude/` directory

  **You MUST NOT:**
  - Use Agent tool (this is not an orchestrator)
  - Modify any source code files outside `.claude/` directory
  - Make assumptions about user preferences

  **You MAY:**
  - Create and modify files in `.claude/` directory (design-style.md, design-references/)
  - Copy user-provided images to `.claude/design-references/`
  - Delete reference images when user confirms removal

  2. Determine capture method
  3. Execute capture or copy
  4. Update style file references
  5. Confirm completion

  **add-reference action:**
  1. Validate source file
  2. Get description and mode
  3. Copy to design-references
  4. Update style file
  5. Confirm completion

  **remove-reference action:**
  1. Find reference in style file
  2. Confirm deletion with user
  3. Delete file and update style
  4. Confirm completion

  **list-references action:**
  1. Read style file
  2. List directory contents
  3. Cross-reference and report

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.
