# Skills

Skills are reusable capability packages for Xpert agents. A skill gives an agent a focused set of instructions, supporting files, prompt workflows, scripts, templates, or task-specific behavior that can be installed once and reused across workspaces and agents.

Use skills when a capability is repeatable but does not need a full tool integration. For example, a team can install a code review skill, a document co-authoring skill, a presentation skill, or an internal operating procedure skill, then let agents load those instructions only when the task needs them.

## What Skills Provide

* **Reusable instructions**: each skill is centered around a `SKILL.md` file that explains when and how the agent should use it.
* **Supporting resources**: a skill can include scripts, references, templates, assets, or examples.
* **Workspace installation**: installed skills live in a workspace and can be browsed, edited, uploaded, or removed from the workspace skills workbench.
* **Runtime enablement**: agents can load selected skills through Skills Middleware and expose them to ChatKit runtime selection.
* **Organization sharing**: workspace-uploaded skills can be shared to the organization skill market for other workspaces to install.
* **Repository discovery**: administrators can connect skill repositories so teams can browse, search, install, and update skills from indexed sources.

## Skill Lifecycle

1. **Discover** skills in the skills market or repository indexes.
2. **Install** a skill into a target workspace.
3. **Inspect and edit** installed skill files in the workspace skills workbench.
4. **Enable** selected skills when creating or configuring an agent.
5. **Run** the agent. Skills Middleware syncs selected skills into the sandbox and adds concise skill metadata to the agent context.
6. **Share or administer** skills through organization-level repositories and template synchronization.

| -------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| Explore / Skills           | Browse featured skills, search indexed repositories, view details, and install or update skills into a workspace.  |
| Workspace / Skills         | Manage installed skills, install from GitHub, upload ZIP packages, register repositories, and edit skill files.    |
| Agent creation             | Select skills while creating a blank agent so Skills Middleware is wired into the primary agent flow.              |
| Agent Studio               | Configure Skills Middleware defaults and command exposure for installed skill commands.                            |
| Settings / Tenant / Skills | Initialize the public skill repository, sync template skills, upload organization skills, and manage repositories. |
