Goose Recipes Skill

Create and work with Goose recipes - reusable configurations that package up specific AI agent setups.

Quick Start

Create a Basic Recipe

Start with the basic template from

assets/basic-recipe-template.yaml

version: "1.0.0"
title: "Your Recipe Title"
description: "What this recipe accomplishes"
prompt: "Initial task for the agent"

Create an Advanced Recipe

For complex workflows, use

assets/advanced-recipe-template.yaml

• Retry logic with success validation
• Structured JSON output
• Subrecipes and extensions
• File input parameters

Core Recipe Creation Workflow

1. Define Required Fields

Every recipe MUST have:

• version

  : Use "1.0.0"

• title

  : Short, descriptive title

• description

  : Detailed explanation of purpose

2. Add Instructions or Prompt

Choose based on use case:

• instructions

  : Multi-step guidance for complex tasks

• prompt

  : Direct task statement for simple tasks
• Both: Instructions provide context, prompt initiates action

3. Configure Parameters

Define inputs with proper requirements:

parameters:
  - key: param_name
    input_type: string  # or "file" to read file contents
    requirement: required  # or "optional" or "user_prompt"
    description: "What this parameter does"
    default: "value"  # Required for optional parameters

Use parameters in templates:

{{ param_name }}

4. Add Extensions (if needed)

Include MCP servers or tools:

extensions:
  - type: stdio
    name: extension_name
    cmd: command_to_run
    args: [arguments]
    timeout: 300
    description: "What this extension provides"

5. Configure Retry Logic (optional)

Enable automatic retries with validation:

retry:
  max_retries: 3
  checks:
    - type: shell
      command: "test -f output.json"  # Must exit 0 for success
  on_failure: "rm -f output.json"  # Cleanup command

6. Define Structured Output (optional)

Enforce JSON response format:

response:
  json_schema:
    type: object
    properties:
      result:
        type: string
        description: "Main result"
    required: [result]

Common Patterns

File Input Processing

Read and process file contents:

parameters:
  - key: source_code
    input_type: file
    requirement: required
    description: "Source code file to analyze"

prompt: "Analyze this code:\n{{ source_code }}"

Multi-Step Workflows

Use instructions for complex procedures:

instructions: |
  1. Parse the input data
  2. Validate against schema
  3. Generate report with findings
  4. Save to specified location

prompt: "Begin processing {{ input_file }}"

Subrecipe Composition

Combine multiple recipes:

sub_recipes:
  - name: "validate"
    path: "./validation.yaml"
    values:
      strict_mode: "true"

Environment Variables

Recipes can use environment-based secrets:

extensions:
  - type: stdio
    name: github-mcp
    cmd: github-mcp-server
    env_keys: [GITHUB_PERSONAL_ACCESS_TOKEN]

MCP Server Access with Authentication

IMPORTANT: When working with HTTP-based MCP servers that require authentication (Bearer tokens, API keys), do NOT use

sse

streamable_http

Instead, use this pattern:

parameters:
  - key: API_KEY
    input_type: string
    requirement: optional
    description: "API key for MCP server authentication"
    default: "your-api-key"

instructions: |
  **MCP Server Access**
  The MCP server is available at: https://your-server.example.com/mcp
  Authentication: Use Bearer token with API key: {{ API_KEY }}

  The server provides tools for:
  - tool_name_1: Description
  - tool_name_2: Description

  Access these tools by making HTTP requests with the Authorization header.

This approach:

1. Passes authentication credentials as parameters
2. Documents the MCP server URL and available tools in instructions
3. Guides the agent to make authenticated HTTP calls directly
4. Avoids extension configuration issues with custom headers

Validation and Testing

Run Recipe Validation

Recipes are validated for:

• Required fields presence
• Parameter-template matching
• Optional parameters have defaults
• Valid YAML/JSON syntax
• Extension configuration validity

Debug Common Issues

{{ variable }}

default: "value"

Template Features

Parameter Substitution

• Basic:

  {{ parameter_name }}

• With filter:

  {{ content | indent(2) }}

Template Inheritance

{% extends "parent.yaml" %}
{% block content %}Modified content{% endblock %}

Built-in Parameters

• recipe_dir

  : Directory containing the recipe file

File Organization

CLI vs Desktop Formats

CLI Format (root-level fields):

version: "1.0.0"
title: "Recipe"
description: "Description"

Desktop Format (nested in recipe object):

name: "Recipe Name"
recipe:
  version: "1.0.0"
  title: "Recipe"
  description: "Description"

Both formats work with

goose run --recipe
