Prevent Goose from Accessing Files	Using Gooseignore	14

.gooseignore is a text file that defines patterns for files and directories that Goose will not access. This means Goose cannot read, modify, delete, or run shell commands on these files when using the Developer extension's tools.

:::info Developer extension only The .gooseignore feature currently only affects tools in the Developer extension. Other extensions are not restricted by these rules. :::

This guide will show you how to use .gooseignore files to prevent Goose from changing specific files and directories.

Creating your .gooseignore file

Goose supports two types of .gooseignore files:

• Global ignore file - Create a .gooseignore file in ~/.config/goose. These restrictions will apply to all your sessions with Goose, regardless of directory.
• Local ignore file - Create a .gooseignore file at the root of the directory you'd like it applied to. These restrictions will only apply when working in a specific directory.

:::tip You can use both global and local .gooseignore files simultaneously. When both exist, Goose will combine the restrictions from both files to determine which paths are restricted. :::

Automatic .gitignore fallback

If no .gooseignore file is found in your current directory, Goose will automatically use your .gitignore file as a fallback. This means:

1. Priority Order: Goose checks for ignore patterns in this order:

   • Global .gooseignore (if exists)
   • Local .gooseignore (if exists)
   • Local .gitignore (if no local .gooseignore and .gitignore exists)
   • Default patterns (if none of the above exist)

2. Seamless Integration: Projects with existing .gitignore files get automatic protection without needing a separate .gooseignore file.

3. Override Capability: Creating a local .gooseignore file will completely override .gitignore patterns for that directory.

:::info Debug logging When Goose uses .gitignore as a fallback, it will log a message to help you understand which ignore file is being used. :::

Example .gooseignore file

In your .gooseignore file, you can write patterns to match files you want Goose to ignore. Here are some common patterns:

# Ignore specific files by name
settings.json         # Ignore only the file named "settings.json"

# Ignore files by extension
*.pdf                # Ignore all PDF files
*.config             # Ignore all files ending in .config

# Ignore directories and their contents
backup/              # Ignore everything in the "backup" directory
downloads/           # Ignore everything in the "downloads" directory

# Ignore all files with this name in any directory
**/credentials.json  # Ignore all files named "credentials.json" in any directory

# Complex patterns
*.log                # Ignore all .log files
!error.log           # Except for error.log file

Default patterns

By default, if you haven't created any .gooseignore files and no .gitignore file exists, Goose will not modify files matching these patterns:

**/.env
**/.env.*
**/secrets.*

These default patterns only apply when neither .gooseignore nor .gitignore files are found in your project.

Common use cases

Here are some typical scenarios where .gooseignore is helpful:

• Generated Files: Prevent Goose from modifying auto-generated code or build outputs
• Third-Party Code: Keep Goose from changing external libraries or dependencies
• Important Configurations: Protect critical configuration files from accidental modifications
• Version Control: Prevent changes to version control files like .git directory
• Existing Projects: Most projects already have .gitignore files that work automatically as ignore patterns for Goose
• Custom Restrictions: Create .gooseignore when you need different patterns than your .gitignore (e.g., allowing Goose to read files that Git ignores)
