## Summary
- **Remove unused dependencies**: warp (zero imports), paste (zero
invocations), tower-service (zero imports), and heed misplacement in
xet_core_structures
- **Move mockall to dev-dependencies** in xet_client by gating
`#[automock]` with `#[cfg_attr(test, automock)]`
- **Feature-gate simulation module** behind `simulation` cargo feature
in xet_client, making axum, heed, humantime, futures-util,
human-bandwidth, and tower-http optional
- **Replace duration-str with humantime** (~2 deps vs ~78 transitive
deps) across xet_runtime, xet_client simulation, and simulation crate
## Impact
| Metric | Before | After | Change |
|---|---|---|---|
| hf-xet production deps | 371 | 321 | **-50** |
| Workspace total | 575 | 569 | -6 |
## Test plan
- [x] `cargo check --workspace` passes
- [x] `cargo check -p hf-xet` passes (without simulation feature — key
validation)
- [x] `cargo test --workspace` — all tests pass (4 pre-existing auth
test failures in git_xet unrelated to this PR)
- [x] `cargo tree -p hf-xet -e normal --prefix none | sort -u | wc -l`
confirms 321 deps

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Medium risk because it changes dependency graph and Cargo feature
gating (notably `xet-client` simulation modules and CI test features),
which can affect build/test behavior across targets despite minimal
runtime logic changes.
>
> **Overview**
> Reduces workspace dependency surface by removing `duration-str`
(replaced with `humantime`) and trimming other transitive-heavy crates;
updates lockfiles accordingly across the workspace, `hf_xet`, and WASM
builds.
>
> Introduces/propagates a `simulation` Cargo feature: `xet-client`’s
simulation server-related deps become optional and are only
compiled/exported when `feature = "simulation"` is enabled; `git_xet`
adds a `simulation` feature that forwards to dependent crates, and CI
now runs tests with `strict simulation git-xet-for-integration-test`.
>
> Minor repo hygiene updates include ignoring `.claude/` in `.gitignore`
and wiring the `simulation` crate to depend on `xet-client` with
`features = ["simulation"]` (plus swapping its duration parsing helper
to `humantime`).

Git-Xet is a Git LFS custom transfer agent that implements upload and download of files using the Xet protocol. Install git-xet, follow your regular workflow to git lfs track ... & git add ... & git commit ... & git push, and your files are uploaded to Hugging Face repos using the Xet protocol. Enjoy the dedupe!
Installation
Prerequisite
Make sure you have git and git-lfs installed and configured correctly.
macOS or Linux (amd64 or aarch64)
To install using Homebrew:
brew install git-xet
git xet install
Or, using an installation script, run the following in your terminal (requires curl and unzip):
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/huggingface/xet-core/refs/heads/main/git_xet/install.sh | sh
To verify the installation, run:
git xet --version
Windows (amd64)
Using winget:
winget install git-xet
Using an installer:
- Download
git-xet-windows-installer-x86_64.zip(available here) and unzip. - Run the
msiinstaller file and follow the prompts.
Manual installation:
- Download
git-xet-windows-x86_64.zip(available here) and unzip. - Place the extracted
git-xet.exeunder aPATHdirectory. - Run
git-xet installin a terminal.
To verify the installation, run:
git xet --version
Uninstall
macOS or Linux
Using Homebrew:
git xet uninstall
brew uninstall git-xet
If you used the installation script (for MacOS or Linux), run the following in your terminal:
git xet uninstall
sudo rm $(which git-xet)
Windows
If you used winget:
winget uninstall git-xet
If you used the installer:
- Navigate to Settings -> Apps -> Installed apps
- Find "Git-Xet".
- Select the "Uninstall" option available in the context menu.
If you manually installed:
- Run
git xet uninstallin a terminal. - Delete the
git-xet.exefile from the location where it was originally placed.
How It Works
Git-Xet works by registering itself as a custom transfer agent to Git LFS by name "xet". On git push, git fetch or git pull, git-lfs negotiates with the remote server to determine the transfer agent to use. During this process, git-lfs sends to the server all locally registered agent names in the Batch API request, and the server replies with exactly one agent name in the response. Should "xet" be picked, git-lfs delegates the uploading or downloading operation to git-xet through a sequential protocol.
For more details, see the Git LFS Batch API and Custom Transfer Agent documentation.
