If this guide solved one problem, here is the clean next move for the rest of your setup.
Most operators land on one fix first. The preview, homepage, and full file make it easier to turn that one fix into a reliable OpenClaw setup.
ChatGPT plugins launched with excitement and got quietly deprecated. Custom GPTs replaced them. Meanwhile, OpenClaw's Skills system took a fundamentally different architectural approach. Here's an honest comparison.
What Happened to ChatGPT Plugins
ChatGPT plugins were third-party integrations for web browsing, code execution, and external services. They were stateless, conversation-scoped, and required you to be present. OpenAI deprecated them in 2024 in favor of Custom GPTs with Actions.
ChatGPT Custom GPTs + Actions
Custom GPTs are configured ChatGPT variants with specific instructions and API integrations. More flexible than plugins, but still fundamentally a chat interface — you're present, you're prompting, session ends and context resets.
OpenClaw Skills Architecture
OpenClaw Skills are persistent, file-based behavior modules that live in your agent's workspace:
~/.openclaw/skills/
slack/SKILL.md # Slack integration behavior
github/SKILL.md # GitHub workflow automation
weather/SKILL.md # Weather data retrieval
my-custom-skill/SKILL.md # Your own skillA Skill is just a Markdown file with instructions. No API registration, no OAuth dance, no external dependency. Write the behavior, your agent reads it. You can build a new skill in 20 minutes.
Key Differences
Persistence: Custom GPTs mostly reset between conversations. OpenClaw agents maintain MEMORY.md across all sessions indefinitely.
Background execution: Custom GPTs only run when you're actively chatting. OpenClaw Skills can be triggered by cron jobs while you're sleeping.
Customization: Custom GPTs are configured through a form. OpenClaw Skills are plain Markdown — infinitely flexible, version-controllable, shareable as files.
Installing OpenClaw Skills
# Install a community skill
clawhub install weather
clawhub install github
# Or write your own skill file
mkdir ~/.openclaw/skills/my-workflow
# Add SKILL.md with your instructionsSee also: OpenClaw vs Claude Desktop and OpenClaw vs Gemini Extensions.
The OpenClaw Playbook ($9.99) includes a chapter on building and publishing your own Skills — including how to monetize them on Claw Mart.
Frequently Asked Questions
Are OpenClaw Skills similar to ChatGPT Custom GPTs?
They serve similar purposes but Skills are files in your local workspace while Custom GPTs are cloud-hosted configurations. Skills work offline, are version-controllable, and can run without you being present.
Can I use OpenClaw Skills without building my own?
Yes. The ClawHub marketplace has community-built skills you can install with one command: `clawhub install [skill-name]`. Skills exist for Slack, GitHub, weather, X/Twitter, and many more.
Does OpenClaw have a marketplace like the GPT Store?
Yes — Claw Mart (shopclawmart.com) is the Skills marketplace. Unlike the GPT Store, skills are portable files, not platform-locked. You own them and can run them on any OpenClaw installation.
Can OpenClaw Skills call external APIs like ChatGPT Actions?
Yes. Skills instruct your agent to call any API, run shell commands, read/write files, or use any tool the agent has access to. Anything your agent can do, a skill can orchestrate.
