Shared source strategy
The same captured Markdown can support both setups: upload it as project files or include it under references/ with SKILL.md.

ChatGPT Projects vs Claude Skills
ChatGPT Projects vs Claude Skills for reusable context
Both can reuse source files, but they differ in portability, trigger behavior, and how explicitly they package a workflow.
Direct answer
ChatGPT Projects are strong for persistent chat context and uploaded files; Claude Skills are stronger as portable, named workflow folders with SKILL.md and references.

Comparison
| Criteria | ChatGPT Projects | Claude Skills |
|---|---|---|
| Primary shape | Project instructions plus uploaded files inside ChatGPT. | A portable folder with SKILL.md and optional references, scripts, and assets. |
| Portability | Useful inside the project environment. | Plain files can be reviewed, versioned, moved, or adapted. |
| Activation | The project context is available inside that project. | The skill description helps the agent decide when to load it. |
| Best fit | Ongoing chats, knowledge work, and Custom GPT-style uploads. | Repeatable agent workflows with named operating procedures. |
Both approaches improve context reuse. The main decision is whether you need a chat workspace or a portable workflow package.
Where createskills fits
createskills produces clean Markdown references that can be uploaded to ChatGPT Projects or placed inside a skill folder. The same source capture should not be trapped in one product if the team needs reuse across tools.
Choose by workflow
Use a project when the work lives in one ongoing chat space. Use a skill when the workflow needs a named trigger, repeated procedure, or file package that can move between environments.
Keep instructions concise
In either model, long source material belongs in files. The instructions should explain when to use the files, how to cite uncertainty, and what output format to return.

Questions people ask
Can I use the same Markdown in both tools?
Yes. That is the point of keeping source captures as normal files.
Which is better for teams?
Teams often prefer portable files because they can review, version, and adapt them across tools.
Do I need a skill for every project?
No. Use skills for repeated workflows, not one-off chats.
