What it does
The repository combines prompt-writing references in the Agent Skills format. The main file, a single consolidated `skills/prompt-engineering-guide/references/full.md`, comes with a short `SKILL.md` index, and split guides sit beside it: strategies for Claude, GPT and Gemini, prompts for images and video, research and fact-checking, slides, expert domain priming, a context engineering collection and a prompt variation guide. The `/prompt`, `/auto-prompt`, `/prompt-sync` and `/prompt-update` commands help build and update prompts, and instructions for ChatGPT GPTs and Gemini Gems carry the same knowledge into browser assistants. Documentation is written in Korean.
Who it is for. People who write prompts for several models at once, keep a library and want the agent to pick a strategy for the chosen model.
Good fit when
- A prompt for image generation is needed with an exact aspect ratio and a list of elements.
- The same request is prepared in variants for Claude, GPT and Gemini.
- A research prompt must include fact-checking to a standard, not only search.
- For slides, structure and text are built through the presentation guide.
Not a fit when
- You need one compact skill without large references.
- You work with models other than Claude, GPT and Gemini.
- Preparing prompts is not part of your tasks.
Example request
Write a poster generation prompt in three variants for Claude, GPT and Gemini and check each against the image guide.Limitations
Model knowledge ages quickly, so recommendations are tied to dates and versions inside the files and should be checked against provider documentation. The largest file is not meant to load in full by default: install only what you need. ChatGPT GPTs have a ten knowledge-file limit and need the `scripts/export-knowledge.sh` script. The licence type was not auto-detected, so read `LICENSE` before commercial use. Documentation is written in Korean.
How to disable. Remove the plugin with `/plugin uninstall prompt-engineering-skills` or the folders from `~/.claude/skills/` and files from `~/.claude/commands/` that you copied by hand.
