How to share AI prompts with your team, and keep everyone on the same version

Why shared prompts drift

A prompt that works gets copied. One person pastes it into Claude's project instructions, another into ChatGPT's custom instructions, a third keeps it in a notes app. A month later, the owner improves it, and three versions are in use. Nobody can say which one wrote the proposal a client complained about.

The problem isn't where the prompt is stored. It's that each person's AI holds its own copy. Any fix has to reach every copy, by hand.

Three ways compared

PromptHub's plans from prompthub.us/pricing, read 4 November 2026.

Option 1: a shared doc

Give each prompt its own heading, a one-line "use when", the owner's name and the date it last changed. Link the doc from wherever the team works. It costs nothing and works on every plan of every AI. It breaks when the prompts get longer, more numerous, or change often, because each paste is a copy.

Option 2: a prompt manager

Prompt managers such as PromptHub describe themselves as a home for prompt engineering: discover, manage, version, test and deploy prompts. They suit a team whose prompts run inside its own product, where an API call fetches the current version and a test run catches regressions. For people who use the prompts in Claude or ChatGPT chats, the last step is still copy and paste.

Option 3: turn prompts into skills

A skill is the same instructions in the open skill format: a name, a description that says what it does and when to use it, then the steps. Claude, ChatGPT, Claude Code, Codex and other agents read this open format, and pick a skill by its description, so nobody has to remember which prompt to paste.

Sharing is the catch. ChatGPT's Skills are on Business, Enterprise, Healthcare and Edu only, and Claude's sharing works inside one organization. For a team on mixed plans and mixed AIs, keep the skills in one place and connect each person's AI to it over MCP: Claude on any plan with custom connectors, ChatGPT on Pro (read only: saving and edits happen in the AI Skill Pod app or in Claude), Business and Enterprise. OpenAI doesn't list ChatGPT Plus for custom MCP connectors. A Plus user pastes the text.

1. List the prompts people reuse weekly and pick the three that matter most.
2. Turn each into a skill: a clear name, a "Use when ..." description, numbered steps, an output template and one example.
3. Test each on three real inputs and fix what goes wrong.
4. Put them in one shared place that every teammate's AI reads, and name an owner for each.
5. Retire the old copies in the doc and in people's custom instructions, so there is one version left.

Keep it from sprawling

A shared library grows fast. Give each skill an owner, keep one skill per task, and prefer adding the team's own rules to a shared skill over copying it. The five rules for keeping team skills from sprawling cover forks, owners and review dates.

Questions

What's the easiest way to share prompts with a team?

A shared doc with one section per prompt, an owner and a last-changed date. It is free and everyone can open it. It drifts as soon as people paste copies into their own AI, so it suits a few prompts that rarely change.

Is a prompt library the same as a skill library?

Close. A prompt library stores text someone pastes. A skill library stores the same instructions as skills, each with a name and a 'use when' description, so the AI picks the right one by itself and the team doesn't paste anything.

How do I share prompts between Claude and ChatGPT users?

Write each prompt once as a skill, in the open format both read, and serve the skills from one place both connect to over MCP: Claude on any plan with custom connectors, ChatGPT on Pro, Business or Enterprise. OpenAI doesn't list ChatGPT Plus for custom MCP connectors. Plus users paste the text.
