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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00000 | $0.01689 |
| Opus 5 | $0.00000 | $0.00844 |
| Sonnet 5 | $0.00000 | $0.00338 |
| Haiku 4.5 | $0.00000 | $0.00169 |
Grade A, and why
gemini-image-skill 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 — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini Image Generation Skill
Google Gemini API를 사용한 이미지 생성 스킬. 슬라이드 및 문서용 이미지를 생성합니다.
Purpose
Gemini 2.0 Flash 또는 Imagen 3 모델을 사용하여 문서/슬라이드에 필요한 이미지를 생성합니다. 해상도와 종횡비 선택을 지원하며, 사용자 승인 워크플로우를 포함합니다.
When to Use This Skill
- "Gemini로 이미지 생성해줘"
- "슬라이드용 그림을 Gemini API로 만들어줘"
- "프레젠테이션에 넣을 일러스트 생성"
- 무료 티어 이미지 생성이 필요할 때 (Gemini 2.0 Flash)
- 특정 종횡비가 필요할 때 (16:9, 9:16 등)
Environment Setup
# 1. API 키 설정
export GEMINI_API_KEY="your-api-key"
# 2. 의존성 설치
pip install google-genai Pillow
Workflow
Phase 1: Analysis
- 대상 문서/슬라이드 읽기
- 이미지가 필요한 섹션/슬라이드 식별
- 각 섹션의 핵심 컨셉 추출
Phase 2: Style & Configuration Selection

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gemini-image-skill is a skill published in the GitHub repository jykim/claude-obsidian-skills (50 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,689 tokens. 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.
