What is a skill library?
A skill library is a set of reusable instructions for an AI, not a pile of one-off chats. On this site a skill is a standing brief — Role, Context, Task, Constraints, Output — that you keep in your AI and reuse. An Agent Skill is different: a SKILL.md file an agent such as Claude Code loads by itself.
PromptCorrectly publishes 495 skills as readable briefs, on shelves such as product & strategy, writing & editing, coding & devops, research & analysis, data & analytics and education & coaching. On a plan each one also downloads as an Agent Skill. If you want a directory of other people's GitHub skills, that is a different kind of library.
Two kinds of “skill library”
| A library of skills to read | A directory of Agent Skills | |
|---|---|---|
| What you get | Briefs written in one format that you read, fill in and reuse | An index of SKILL.md repositories other people publish |
| Who uses it | You — in ChatGPT, Claude, Gemini or a custom GPT | Coding agents — Claude Code and other agents that support the format |
| How you use it | Paste once as custom instructions, or keep it in a Project | Install the folder; the agent loads it when a task matches |
| This site | Yes — every skill, same structure | Every skill exports as a SKILL.md on a plan; no index of third-party repos |
Three ways to use a skill from this library
- As standing instructions. Paste it into a Claude Project, a custom GPT or a Gemini Gem. Every chat in that space now starts as that specialist.
- In one chat. Paste it first, then give your task. Fill anything in [BRACKETS] — or let the Studio list the blanks for you.
- As an Agent Skill. On a plan, download the SKILL.md and save it as
.claude/skills/<name>/SKILL.md; Claude Code loads it when the task fits. More in prompt vs skill vs Agent Skill.

Questions
What is the difference between a prompt and a skill?
A prompt does one job once. A skill is a standing instruction — a specialist you set up once and reuse for many tasks of the same kind, such as reviewing code, writing briefs or checking claims.
What is an Agent Skill?
A folder with a SKILL.md file: YAML front-matter with a name and a description, then Markdown instructions. Agents such as Claude Code read the description and load the skill by themselves when a task matches it.
Can I use these skills in ChatGPT?
Yes. Every skill is plain text. Paste it into a custom GPT’s instructions or at the start of a chat. The same text works in Claude and Gemini.
Are the skills free?
One starter skill per main shelf is free with an account, and every skill’s title and opening lines are public. The full library of skills is on the Library and Pro plans.
