Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.01394 |
| Opus 5 | $0.00023 | $0.00697 |
| Sonnet 5 | $0.00009 | $0.00279 |
| Haiku 4.5 | $0.00005 | $0.00139 |
Grade A, and why
obsidian-mermaid 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Mermaid Diagrams
Create Mermaid diagrams that render correctly in Obsidian and publish without issues.
When to Use This Skill
Activate when you need to:
- Create flowcharts, sequence diagrams, ER diagrams
- Convert ASCII art to Mermaid
- Fix Mermaid rendering errors in Obsidian
Core Principle: Simplicity First
다이어그램은 한눈에 들어와야 한다
복잡한 다이어그램은 읽기 어렵다. 항상 최소한의 노드와 연결로 핵심만 표현하라.
Node Minimization
Before (9개 노드):
flowchart LR
A[수집] --> B[정리] --> C[보관]
D[목표] --> E[학습] --> F[실행] --> G[측정] --> H[달성]
After (2개 노드 - 순차 흐름을 노드 내 텍스트로):
flowchart LR
A[수집 → 정리 → 보관]
B[목표 → 학습 → 실행 → 달성]
Connection Minimization
- 핵심 흐름만 표현, 세부사항은 본문에서 설명
- 노드 5개 이하, 연결선 교차 금지
- 복잡한 관계는 여러 개의 단순한 다이어그램으로 분리
Table vs Mermaid 선택
| 형식 | 용도 | 예시 |
|---|---|---|
| 테이블 | 속성-값 매핑, 비교, 옵션 | 에너지 레벨별 작업 |
| Mermaid | 흐름, 프로세스, 피드백 루프 | 입력→처리→출력 |
| 인라인 | 단순 순차 흐름 | A → B → C |
원칙: 같은 정보를 더 컴팩트하게 표현하는 형식 선택
Critical Rules
1. NO Markdown in Labels
Common Errors:
Node["1. First"] → "Unsupported markdown: list"
Node["Text<br/>More"] → "Unsupported markdown: heading"
Node["## Header"] → "Unsupported markdown: heading"
Correct:
Node[First]
Node[Text]
Rule: Keep labels plain text. Move complex descriptions outside the diagram.
2. Prefer Square Layout (정사각형 레이아웃)
Problem: flowchart LR은 너무 넓고, flowchart TB는 너무 길어진다.
Solution: TB + 내부 LR 조합으로 정사각형에 가까운 레이아웃 만들기
flowchart TB
subgraph Layer1["레이어 1"]
direction LR
A[항목A] ~~~ B[항목B] ~~~ C[항목C]
end
subgraph Layer2["레이어 2"]
direction LR
D[항목D] ~~~ E[항목E]
end
Layer1 --> Layer2
패턴:
flowchart TB: 전체 흐름은 위→아래direction LR: 각 subgraph 내부는 가로 배치~~~: 보이지 않는 연결 (화살표 없이 정렬용)
Rule: 세로로 너무 길어지면 subgraph + direction LR 사용.
3. Keep Labels Short
❌ Too long:
Node["This is a very long description that will break layout"]
✅ Short and clear:
Node[Short Label]
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.

obsidian-mermaid is a skill published in the GitHub repository jykim/claude-obsidian-skills (50 stars, last pushed 20d ago), licensed MIT. It adds 45 tokens to every session and 1,394 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
