# Cargo CLI — Content Workspace **knowledge** management: upload and organize **files** (PDFs, CSVs, text) and group or sync them into **libraries**. These are the binary/grouped knowledge resources that ground agent responses (retrieval-augmented generation, RAG). > **New top-level domain (CLI ≥ 1.0.19).** Files and libraries moved out of the `ai` domain into the `content` domain — `cargo-ai content file …` and `cargo-ai content library …`. The old `cargo-ai ai file …` commands no longer exist; an `unknown command` error means you're on the old path. > For **attaching** a file or library to an agent (via the release `resources` array), use [`cargo-ai`](../cargo-ai/SKILL.md). > For **folders** that organize files, use [`cargo-workspace-management`](../cargo-workspace-management/SKILL.md) (`cargo-ai workspaceManagement folder …`). > For batch-run **input** files (CSVs uploaded to drive a batch), that's a different surface — `cargo-ai workspaceManagement file upload` — documented in [`cargo-workspace-management`](../cargo-workspace-management/SKILL.md). > See `references/examples/files.md` for end-to-end file, library, and attach-to-agent examples. > See `references/response-shapes.md` for full JSON response structures. > See `references/troubleshooting.md` for common errors and how to fix them. ## Bootstrap Already signed in (`cargo-ai whoami` returns a workspace)?
