What it does
Image Prompt Guide is an agent skill from treylom/prompt-engineering-skills. Use when generating AI image prompts — 원본 = 공냥 프롬프트 킷 v4(gpt-image-2 텍스트 프롬프트 계약 — 포맷 A/B·철칙·jsonl·검증기, skills/image-prompt-kit/ vendor 원문). 웹 UI(ChatGPT/Gemini) JSON 간이 경로는 legacy 부록. /prompt 커맨드가 이미지 타겟 감지 시 references/full.md 전체 로드.
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/full.md`).
It sits in Media & Creative, covering Image generation. It works with OpenAI. The repository describes itself as: Comprehensive AI prompt engineering skills for Claude Code, ChatGPT (GPTs & Codex CLI plugin), and Gemini Gems. Model-specific patterns for Claude Opus 5.5 / Fable 5.1 (Opus 5 /…

What it can do on your machine
Read from SKILL.md and the folder at commit 4dacb68. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Image Prompt Guide loads about 346 tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 130 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 130 words (~346 tokens).
“공냥 킷 원문 = ../image-prompt-kit/ (무수정 vendor — §K5 라우팅 표가 지시하는 파일을 직접 읽는 것은 우회가 아니다). 검증기 = ../image-prompt-kit/scripts/check_prompt.mjs.”
