# rag-add-source — add a source > Before executing this workflow, read and apply `../HOST_CONTRACT.md`. ## Steps 1. **Precondition check**: call `rag_get_settings`. If absent, guide to `/rag:init-rag` and stop. 2. **Path parsing**: extract the path (or a single file) from the user's utterance. - Absolute path or a relative path from the project root - For a directory, `recursive: true`; for a single file, `recursive` is ignored - Existence check: Bash `test -e <path>`. If absent, confirm with the user → create it / stop. 3. **include/exclude**: default is `["**/*.md", "**/*.mdx", "**/*.txt", "**/*.pdf", "**/*.png", "**/*.jpg", "**/*.jpeg", "**/*.gif", "**/*.webp"]`. If the user gives a hint like "code too", "ts/js", "py", expand accordingly. Confirm once with the host question tool: - Markdown·text·PDF·image (default) - Include code too (`**/*.py`, `**/*.ts`, …) - User-specified 4. **Duplicate check**: if the same path already exists in the current settings.sources, ask whether to update that entry before proceeding. 5. **Update settings**: take the `rag_get_settings` result, add/update the new entry in the sources array → `rag_set_settings(settings)`. 6. **Partial indexing**: call `rag_diff_files(source_path=<the path>)`. Process only the resulting added/changed (same method as `/rag:rag-reindex` step 4). 7. **Result summary**: ``` ✅ Source added: <path> include: ... Newly indexed: N files / N chunks ``` ## Error handlin
