This behavior can be configured via the `fileFiltering` settings. - **File Types:** The command is intended for text-based files. While it might attempt to read any file, binary files or very large files might be skipped or truncated by the underlying `read_many_files` tool to ensure performance and relevance. The tool will typically indicate if files were skipped. - **Output:** The CLI will show a tool call message indicating that `read_many_files` was used, along with an improved display message detailing the status (e.g., number of files read, total size) and the path(s) that were processed. diff --git a/docs/cli/configuration.md b/docs/cli/configuration.md index da5a6bfd..4367e73e 100644 --- a/docs/cli/configuration.md +++ b/docs/cli/configuration.md @@ -42,6 +42,22 @@ When you create a `.gemini/settings.json` file for project-specific settings, or - **Default:** `GEMINI.md` - **Example:** `"contextFileName": "AGENTS.md"` +- **`fileFiltering`** (object, optional): + + - **Description:** Controls git-aware file filtering behavior for @ commands and file discovery tools. + - **Properties:** + - **`respectGitIgnore`** (boolean, default: `true`): Whether to respect .gitignore patterns when discovering files.
