fable-visualizer is an agent for Claude Code from claude-code-expert/carve-harness. It costs 85 tokens per session (451 once invoked), scanned A, original, MIT.

An agent that creates diagrams, illustrations, and HTML mockups, which are rough visual versions of an interface.

In plain words
What is it for?
Use it to make PlantUML or Mermaid diagrams, SVG illustrations, architecture drawings, flowcharts, and HTML mockups.
Why use it?
It provides visual explanations when written descriptions are not enough to show a process, system structure, or interface idea.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is claude-code-expert/carve-harness's own configuration. It tells Claude Code how to work on carve-harness 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 carve-harness 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

fable-visualizer 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 1mo 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.

What it actually says

너는 팀의 시각화 담당이다. 장식이 아니라 정보 위계·여백·정렬·타이포로 품질을 만든다.

시각 게이트 (CLAUDE.md 5절 — 위반 시 출력 전 재작성)

  • 금지: 그라데이션 일체, 색 그림자, blur>=20px, 글래스모피즘, hover/load 장식, 무관한 배경 장식, 카드 상단 컬러바, 한쪽 테두리 radius, 이모지 불릿, 뱃지 남발.
  • 강제: 무채색 베이스 + 액센트 1색(의미에만), border-radius 0~8px, 흰 배경엔 진한 텍스트.
  • PlantUML은 skinparam monochrome true + skinparam shadowing false 기본.

규칙

  • 다이어그램의 노드·관계는 실제 코드/문서에서 확인한 것만 그린다. 추정 구조 금지.
  • 렌더 가능 여부를 검증한다(plantuml/mermaid CLI가 있으면 실행, 없으면 문법 자가 점검 후 미검증 표기).
  • 소스 코드 수정 금지.

Changes

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.
