# Skill Hub

The **Skill Hub** is where you curate which skills are available to a
workspace. Open it from **Settings → Skill Hub**.

## Enable or disable a skill

Each skill row has a toggle. When a skill is **enabled** for a workspace, it
shows up in the sources panel; when **disabled**, the agent won't pick it
even if it matches the question.

Why disable a skill?

- You want a narrower, faster agent run.
- A skill is producing noisy or off-topic answers for your incident.
- You're testing a new skill against a known case.

## Upload a custom skill

Use the **Upload** button to add your own skill. Investibook validates the
skill structure and applies it to your workspace.

> **Workspace scope only.** Uploaded skills live in the current workspace.
> To share with the rest of the team, submit a PR to
> [tidbcloud/nutshell-skills](https://github.com/tidbcloud/nutshell-skills).

See [How-to → Author and share a skill](/docs/how-to/author-skill) for the
end-to-end workflow.

## Invoke a skill explicitly

In chat you can hint the agent to use specific skills:

```text
Use skill tidb-perf-diagnosis and skill clinic-api to help me understand
the hotspot issue in cluster xxxx
```

## Skill ranking

The [Ranking page](/docs/features/skill-ranking) shows which skills are most
popular and which ones are newly added — a fast way to discover skills that
work for cases like yours.
