Skills
Give Nebula and your agents reusable skills — upload a SKILL.md, install one from a URL, or browse the ClawHub registry, then call them with @skill in chat.
Skills are reusable instructions you teach Nebula once and reuse forever. Write up how you want a task done — your invoice format, your code-review checklist, your brand voice — save it as a skill, and any agent can follow it on demand instead of you re-explaining every time.
What a skill is
A skill is a single Markdown file (a SKILL.md) with a name and a set of instructions. It lives in your workspace's brain alongside memories, and agents pull it in when it's relevant to the task at hand. You manage skills from Settings → Skills (under Workspace brain).
Reusable, not one-off
Capture a procedure once. Every future request that needs it follows the same steps, the same way.
Shared across your workspace
Skills you add are available to everyone in the workspace — a shared playbook your whole team's agents can draw on.
Scope: Nebula or a specific agent
When you add a skill, you choose who it belongs to. A scope badge on each skill card shows which it is.
Attach the skill to Nebula itself so it applies broadly — whenever Nebula coordinates work that fits, the skill is in play.
Attach it to one agent — your code agent, your research agent — so the instructions only apply when that agent is doing the work.
Adding a skill
There are three ways to add one, all from the All skills tab.
Pick a scope (Nebula or an agent), then upload a SKILL.md file with your instructions. This is the route when you've written the skill yourself.
Paste a direct link to a SKILL.md — a GitHub raw link, say. Nebula safety-scans it before installing, then asks whether to attach it to Nebula or a specific agent.
Open the Registry tab and search the ClawHub skill registry by what you want to do — "pdf generation", "code review" — then install a match to Nebula or an agent.
Using a skill in chat
Reference any skill with @skill:name in a thread to point an agent at it directly:
@skill:invoice-parser pull the line items out of this PDF and total themYou usually don't have to — agents reach for a relevant skill on their own — but calling it by name guarantees the instructions are applied for that request.
Where a skill came from
Each skill card carries an origin badge so you can tell at a glance how it got into your workspace.
| Badge | Meaning |
|---|---|
| Authored | You wrote it directly in Nebula |
| Uploaded | You uploaded a SKILL.md file |
| From URL | Installed from a remote link |
| From registry | Installed from the ClawHub registry |
Not sure how to write a skill? Ask Nebula in chat — describe the procedure and it can draft the SKILL.md for you. For anything unresolved, email support@nebula.gg.
