 - **Keep file updated**: Regularly update the `.goosehints` file to reflect any changes in project protocols or priorities.
 - **Be concise**: Make sure the content is straightforward and to the point, ensuring Goose can quickly parse and act on the information.
 - **Start small**: Create a small set of clear, specific hints and gradually expand them based on your needs. This makes it easier to understand how Goose interprets and applies your instructions.

+## Custom Context Files
+
+Goose looks for `.goosehints` files by default, but you can configure a different filename or multiple context files using the `CONTEXT_FILE_NAMES` environment variable. This is useful for:
+
+- **Tool compatibility**: Use conventions from other AI tools (`AGENTS.md`, `CLAUDE.md`)
+- **Organization**: Separate frequently-used rules into multiple files that load automatically
+- **Project conventions**: Use context files from your project's established toolchain (`.cursorrules`)
+
+Here's how it works:
+1. Goose looks for each configured filename in both global (~/.config/goose/) and local (current directory) locations
+2. All found files are loaded and combined into the context
+
+### Configuration
+
+Set the `CONTEXT_FILE_NAMES` environment variable to a JSON array of filenames. If not set, it defaults to `[".goosehints"]`.
+
+```bash
+# Single custom file
+export CONTEXT_FILE_NAMES='["AGENTS.md"]'
+
+# Multiple files (loaded in order)
+export CONTEXT_FILE_NAMES='["CLAUDE.md", ".goosehints", "project_rules.txt"]'
+```
