Skills turn the way you already work into reusable workflows that ChatGPT can follow consistently—so you spend less time re-explaining steps, formats, and requirements, and more time getting to a solid result.
If you’ve ever found yourself reusing the same prompt or pasting the same template again and again, skills are designed to fix that.
A skill is a reusable, shareable workflow that tells ChatGPT how to do a specific task. Rather than starting from scratch each time, you define the process once so it can be applied reliably whenever the task comes up.
A skill typically includes:
Skills are most useful when getting a good output from ChatGPT depends on following a repeatable approach—especially when tasks involve multiple steps, structured formats, or specific requirements.
## What’s a SKILL.md file?
A SKILL.md file is the skill’s playbook: a plain-text set of instructions that tells ChatGPT how to run a workflow consistently. It’s written in Markdown (the “.md” part), a lightweight formatting style that uses simple symbols—like "#" for headings and "-" for lists—so the file is easy to read and edit in most tool.
Because it’s plain text and Markdown-based, SKILL.md is portable. It can be shared, versioned, and reused across tools. It’s also designed as an open standard(opens in a new window), so similar patterns may appear in other AI apps and platforms.
A typical SKILL.md file defines:
## How to build and use skills
#### 1) Think of a repeatable task
Good first skills come from work you already do often—especially where consistency matters. This might include monthly reporting, recurring executive updates, or compliance-safe summaries.
Ensure you know the input (what the user will typically provide, like files, links, context, fields), the output (the expected format, tone, and length of the final product), and any guardrails (what must be included and what must not happen).
There are a few different patterns we usually see in skills:
_Design tip:_ _Skills often work best as__small building blocks__you can mix and match, rather than one massive end-to-end skill. For complex workflows, consider splitting them into smaller skills._
#### 2) Write down the instructions
_If you’re new to building skills, start by opening a new chat and prompting ChatGPT with “Build me a skill…”. You can also build skills outside of ChatGPT and__upload them_(opens in a new window)_._
Ask ChatGPT to create a skill, and fill in the rest of the prompt with a description of the skill you want ChatGPT to build. A strong set of instructions typically includes:
_Tip: Drafting the workflow by speaking or dictating to ChatGPT can help generate a first version more quickly._
#### 3) Review and install the skill
ChatGPT will generate a draft of the skill and present an option to install it. Review the draft, refine the instructions if needed, and select Install to add it to your workspace..
#### 4) Use it in day-to-day work
Once enabled in your workspace, ChatGPT can use a relevant skill automatically—or you can select one explicitly by @-mentioning it.
#### 5) Share or keep it personal
If supported by your workspace settings, you can share your skill with others in your workspace, or even install it on their behalf. Note that workspace owners have full control of who can share and install skills.
## How skills, GPTs, and projects work together
These tools serve different but complementary purposes. Here’s a simple framework to think about how they fit together:
