Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 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.

<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.
