:::caution Deprecated
This extension has been deprecated and is only available in v1.16.0 - v1.24.0. For v1.25.0+, see the [Summon extension](/docs/mcp/summon-mcp).
:::
The Skills extension loads *skills* &mdash; reusable sets of instructions that teach goose how to perform specific tasks or follow particular workflows.
goose automatically discovers skills at startup and uses them when relevant to your request. goose loads skills from `.agents/skills/` in your project directory and `~/.config/agents/skills/` globally, making skills portable across different AI coding agents. To learn about creating skills and how goose uses them, see [Using Skills](/docs/guides/context-engineering/using-skills).

The Summon extension lets you load knowledge into goose's context and delegate tasks to [subagents](/docs/guides/subagents).
You can load different types of sources:
- [**Skills**](/docs/guides/context-engineering/using-skills) - Reusable instruction sets that teach goose specific workflows
- [**Recipes**](/docs/guides/recipes) - Automated task definitions with prompts and parameters
This is useful for teaching goose how to perform tasks and running work in parallel through subagents.

## Example Usage
In this example, we'll create a custom skill that teaches goose a 90s web aesthetic, then use Summon to load that skill and delegate a subagent to build a retro homepage.
### Create a Skill
```markdown title=".agents/skills/retro/SKILL.md"
---
name: retro
description: Creates content with 90s web aesthetic
---
# Retro Web Guidelines
Channel the 90s internet:
1. Bright colors, especially neon
2. Comic Sans or pixel fonts
3. Animated GIF energy (use emojis as a substitute)
4. "Under construction" vibes
5. Visitor counters, guestbook mentions
6. Marquee-style excitement
```
### goose Prompt
```
Load the retro skill with summon. Then delegate a subagent to create an HTML page called my-site.html for a personal homepage.
```
### goose Output
```
─── load | summon ───────────────────────────────────────────
source: retro
# Loaded: retro (skill)
## retro (skill)
