Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.05431 |
| Opus 5.5 | $0.00018 | $0.02172 |
| Sonnet 5.5 | $0.00009 | $0.01086 |
| Haiku 4.5 | $0.00005 | $0.00543 |
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 23d 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.
This is a copy
100% identical to create-style — 191 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 — 677 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Read ${CLAUDE_PLUGIN_ROOT}/skills/design-references/SKILL.md and ${CLAUDE_PLUGIN_ROOT}/skills/ui-style-format/SKILL.md before the first step; they hold the reference this command follows.
<user_request> $ARGUMENTS </user_request>
**You MUST:**
- Use AskUserQuestion for all user input gates
- Use Write to create .claude/design-style.md
- Use Read to check for existing style file
- 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
</implementer_role>
<phase_reporting>
There are no task-list tools. Announce each phase in one line of text
(`**Phase N — starting.**` / `**Phase N — complete.**`, naming its artifacts). The
style file and `.claude/design-references/` are the record.
</phase_reporting>
</critical_constraints>
`update`, with or without a section, needs an existing `.claude/design-style.md`. If
the file is missing, reply "No style yet. Run `/designer:create-style create`." and stop.

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.
