+description: Find open Dependabot PRs for the current GitHub repo, compare each PR head to its base branch, replay only the net dependency changes in a fresh worktree and branch, run npm validation, and optionally commit, push, and open a PR. Use when you want to batch or manually replicate active Dependabot updates.
+license: MIT
+compatibility: Requires git, git worktree, gh CLI auth, npm, and a GitHub repo with an origin remote.
+---
+
+# Dependabot PR Rollup
+
+## When to use
+
+Use this skill when the user wants to:
+- find all open Dependabot PRs in the current repo
+- reproduce their net effect in one local branch
+- validate the result with the repo's standard npm checks
+- optionally commit, push, and open a PR
+
+## Workflow
+
+1. Inspect the current checkout state, but do not reuse a dirty worktree.
+2. List open Dependabot PRs with `gh pr list --state open --author app/dependabot`.
+3. For each PR, collect the title, base branch, head branch, changed files, and relevant diffs.
+4. Compare each PR head against `origin/<base>` instead of trusting the PR title. Dependabot PRs can already be partially merged, superseded by newer versions, or have no remaining net effect.
+5. Create a new worktree and branch from `origin/<base>`.
+6. Reproduce only the remaining dependency changes in the new worktree.
+   - Inspect `package.json` before editing.
+   - Run `npm ci --ignore-scripts` before applying updates.
+   - Use `npm install ... --ignore-scripts` for direct dependency changes so `package-lock.json` stays in sync.
+7. Run `npm run all`.
+8. If requested, commit the changed source, lockfile, and generated artifacts, then push and open a PR.
+
+## Repo-specific notes
+
+- Use `gh` for GitHub operations.
+- Keep the user's original checkout untouched by working in a separate worktree.
+- In this repo, `npm run all` is the safest validation command because it runs build, check, package, and test.
+- If dependency changes affect bundled output, include the regenerated `dist/` files.
+
+## Report back
+
+Always report:
+- open Dependabot PRs found
+- which PRs required no net changes
+- new branch name
+- new worktree path
+- files changed
+- `npm run all` result
+- if applicable, commit SHA and PR URL

+# setup-uv agent notes
+
+This repository is a TypeScript-based GitHub Action for installing `uv` in GitHub Actions workflows. It also supports restoring/saving the `uv` cache and optional managed-Python caching.
+
+- The published action runs the committed bundles in `dist/`, not the TypeScript in `src/`. After any code change, run `npm run package` and commit the resulting `dist/` updates.
+- Standard local validation is:
+  1. `npm ci --ignore-scripts`
+  2. `npm run all`
+- `npm run check` uses Biome (not ESLint/Prettier) and rewrites files in place.
+- User-facing changes are usually multi-file changes. If you add or change inputs, outputs, or behavior, update `action.yml`, the implementation in `src/`, tests in `__tests__/`, relevant docs/README, and then re-package.
+- The easiest areas to regress are version resolution and caching. When touching them, add or update tests for precedence, cache invalidation, and cross-platform path behavior.
+- Workflow edits have extra CI-only checks (`actionlint` and `zizmor`); `npm run all` does not cover them.
+- Source is authored with bundler-friendly TypeScript, but published action artifacts in `dist/` are bundled as CommonJS for maximum GitHub Actions runtime compatibility with `@actions/*` dependencies.
+- Keep these concerns separate when changing module formats:
+  - `src/` and tests may use modern ESM-friendly TypeScript patterns.
+  - `dist/` should prioritize runtime reliability over format purity.
+  - Do not switch published bundles to ESM without validating the actual committed artifacts under the target Node runtime.
+- Before finishing, make sure validation does not leave generated or formatting-only diffs behind.

 ## Usage
 
-Example workflow in a real world project can be found [here](https://github.com/eifinger/hass-weenect/blob/main/.github/workflows/ci.yml)
+### Install a required-version or latest (default)
-
-### Install specific version
-
-You can also specify a specific version of uv
 
 ```yaml
-- name: Install a specific version
+- name: Install the latest version of uv
-  uses: eifinger/setup-uv@v1
+  uses: astral-sh/setup-uv@v7
+```
+
+If you do not specify a version, this action will look for a [required-version](https://docs.astral.sh/uv/reference/settings/#required-version)
+in a `uv.toml` or `pyproject.toml` file in the repository root. If none is found, the latest version will be installed.
+
+For an example workflow, see
+[here](https://github.com/charliermarsh/autobot/blob/e42c66659bf97b90ca9ff305a19cc99952d0d43f/.github/workflows/ci.yaml).

-### Install latest version
+### Outputs
 
-By default this action installs the version defined as `default` in `action.yml`.
+- `uv-version`: The installed uv version. Useful when using latest.
-This gets automatically updated in a new release of this action when a new version of uv is released.
+- `uv-path`: The path to the installed uv binary.
-If you don't want to wait for a new release of this action you can use use `version: latest`.
+- `uvx-path`: The path to the installed uvx binary.
+- `cache-hit`: A boolean value to indicate a cache entry was found.
+- `venv`: Path to the activated venv if activate-environment is true.
+- `python-version`: The Python version that was set.
+- `python-cache-hit`: A boolean value to indicate the Python cache entry was found.
 
-> [!WARNING]  
+### Python version
-> Using the `latest` version means that the uv executable gets downloaded every single time instead of loaded from the tools cache.
+
-> This can take up to 20s depending on the download speed.
+You can use the input `python-version` to set the environment variable `UV_PYTHON` for the rest of your workflow
-> This does not affect the uv cache.
+
+This will override any python version specifications in `pyproject.toml` and `.python-version`
 
 ```yaml
-- name: Install a specific version
+- name: Install the latest version of uv and set the python version to 3.13t

   with:
-    version: 'latest'
+    python-version: 3.13t
+- run: uv pip install --python=3.13t pip
 ```
 
-### Validate checksum
+You can combine this with a matrix to test multiple Python versions:
-
-You can also specify a checksum to validate the downloaded file.
-Checksums up to the default version are automatically verified by this action.
-The sha265 hashes can be found on the [releases page](https://github.com/astral-sh/uv/releases)
-of the uv repo.

 ```
 
-### Enable caching
+### Working directory
 
-If you enable caching the [uv cache](https://docs.astral.sh/uv/concepts/cache/) will
+You can set the working directory with the `working-directory` input.
-be cached to the GitHub Actions Cache. This can speed up runs which can reuse the cache
+This controls where we look for `pyproject.toml`, `uv.toml` and `.python-version` files
-by several minutes. The cache will always be reused on self-hosted runners.
+which are used to determine the version of uv and python to install.
 
-You can optionally define a custom cache key suffix.
+It also controls where [the venv gets created](#activate-environment), unless `venv-path` is set.
 
 ```yaml
-- name: Enable caching and define a custom cache key suffix
+- name: Install uv based on the config files in the working-directory
-  id: setup-uv
+  uses: astral-sh/setup-uv@v7
-  uses: eifinger/setup-uv@v1
   with:
-    enable-cache: true
+    working-directory: my/subproject/dir
-    cache-suffix: 'optional-suffix'
 ```
 
-When the cache was successfully restored the output `cache-hit` will be set to `true` and you can use it in subsequent steps.
+## Advanced Configuration
-For the example above you can use it like this:
 
-```yaml
+For more advanced configuration options, see our detailed documentation:
-- name: Do something if the cache was restored
-  if: steps.setup-uv.outputs.cache-hit == 'true'
-  run: echo "Cache was restored"
-```
 
-#### Local cache path
+- **[Advanced Version Configuration](docs/advanced-version-configuration.md)** - Resolution strategies and version files
-
+- **[Caching](docs/caching.md)** - Complete guide to caching configuration
-If you want to save the cache to a local path other than the default path (`/tmp/setup-uv-cache`)
+- **[Environment and Tools](docs/environment-and-tools.md)** - Environment activation, tool directories, authentication, and environment variables
-you can specify the path with the `cache-local-path` input.
+- **[Customization](docs/customization.md)** - Checksum validation, custom manifests, and problem matchers
-
-```yaml
-- name: Define a custom uv cache path
-  uses: eifinger/setup-uv@v1
-  with:
-    enable-cache: true
-    cache-local-path: '/path/to/cache'
-```
-
-#### Cache dependency glob
-
-If you want to control when the cache is invalidated you can specify a glob pattern with the `cache-dependency-glob` input.
-The cache will be invalidated if any file matching the glob pattern changes.
-The glob matches files relative to the repository root.
-
-```yaml
-- name: Define a cache dependency glob
-  uses: eifinger/setup-uv@v1
-  with:
-    enable-cache: true
-    cache-dependency-glob: 'uv.lock'
-```
-
-```yaml
-- name: Define a cache dependency glob
-  uses: eifinger/setup-uv@v1
-  with:
-    enable-cache: true
-    cache-dependency-glob: '**requirements*.txt'
-```
-
-### API rate limit
-
-To avoid hitting the error `API rate limit exceeded` you can supply a GitHub token with the `github-token` input.
-
-```yaml
-- name: Install uv and supply a GitHub token
-  uses: eifinger/setup-uv@v1
-  with:
-    github-token: ${{ secrets.GITHUB_TOKEN }}
-```
 
 ## How it works
 
-This action downloads uv from the releases of the [uv repo](https://github.com/astral-sh/uv) and uses the [GitHub Actions Toolkit](https://github.com/actions/toolkit) to cache it as a tool to speed up consecutive runs on self-hosted runners.
+By default, this action resolves uv versions from the
+[`astral-sh/versions`](https://github.com/astral-sh/versions) manifest and downloads uv from the
+official [GitHub Releases](https://github.com/astral-sh/uv).
 
-The installed version of uv is then added to the runner path so other steps can just use it by calling `uv`.
+It then uses the [GitHub Actions Toolkit](https://github.com/actions/toolkit) to cache uv as a
+tool to speed up consecutive runs on self-hosted runners.
+
+The installed version of uv is then added to the runner PATH, enabling later steps to invoke it
+by name (`uv`).
 
 ## FAQ
 
-### Do I still need actions/setup-python when using this action?
+### Do I still need `actions/setup-python` alongside `setup-uv`?
 
-No! This action was modelled as a drop-in replacement for `actions/setup-python` when using uv.
+With `setup-uv`, you can install a specific version of Python using `uv python install` rather than
+relying on `actions/setup-python`.
 
-A simple example workflow could look like this:
+Using `actions/setup-python` can be faster (~1s), because GitHub includes several Python versions in the runner image
+which are available to get activated by `actions/setup-python` without having to download them.
+
+For example:
 
 ```yaml

     enable-cache: true
 - name: Test
-  run: uv run --frozen pytest
+  run: uv run --frozen pytest  # Uses the Python version automatically installed by uv

-If you have to know the version installed for other steps of your workflow you can use the `uv-version` output:
+If you require the installed version in subsequent steps of your workflow, use the `uv-version`
+output:
 
 ```yaml
 - name: Checkout the repository
   uses: actions/checkout@main
 - name: Install the default version of uv
   id: setup-uv
-  uses: eifinger/setup-uv@v1
+  uses: astral-sh/setup-uv@v7
 - name: Print the installed version
   run: echo "Installed uv version is ${{ steps.setup-uv.outputs.uv-version }}"
 ```

+### Should I include the resolution strategy in the cache key?

+**Yes!**
-[<img src="https://raw.githubusercontent.com/eifinger/setup-uv/main/docs/images/paypal-button.svg" width=150 height=40 style="margin: 5px"/>](https://paypal.me/kevinstillhammer)
+
+The cache key gets computed by using the cache-dependency-glob (see [Caching documentation](docs/caching.md)).
+
+If you have jobs which use the same dependency definitions from `requirements.txt` or
+`pyproject.toml` but different
+[resolution strategies](https://docs.astral.sh/uv/concepts/resolution/#resolution-strategy),
+each job will have different dependencies or dependency versions.
+But if you do not add the resolution strategy as a cache-suffix (see [Caching documentation](docs/caching.md)),
+they will have the same cache key.
+
+This means the first job which starts uploading its cache will win and all other job will fail
+uploading the cache,
+because they try to upload with the same cache key.
+
+You might see errors like
+`Failed to save: Failed to CreateCacheEntry: Received non-retryable error: Failed request: (409) Conflict: cache entry with the same key, version, and scope already exists`
+
+### Why do I see warnings like `No GitHub Actions cache found for key`
+
+When a workflow runs for the first time on a branch and has a new cache key, because the
+cache-dependency-glob (see [Caching documentation](docs/caching.md)) found changed files (changed dependencies),
+the cache will not be found and the warning `No GitHub Actions cache found for key` will be printed.
+
+While this might be irritating at first, it is expected behaviour and the cache will be created
+and reused in later workflows.
+
+The reason for the warning is that we have to way to know if this is the first run of a new
+cache key or the user accidentally misconfigured the cache-dependency-glob
+or cache-suffix (see [Caching documentation](docs/caching.md)) and the cache never gets used.
+
+### Do I have to run `actions/checkout` before or after `setup-uv`?
+
+Some workflows need uv but do not need to access the repository content.
+
+But **if** you need to access the repository content, you have run `actions/checkout` before running `setup-uv`.
+Running `actions/checkout` after `setup-uv` **is not supported**.
+
+### Does `setup-uv` also install my project or its dependencies automatically?
+
+No, `setup-uv` alone won't install any libraries from your `pyproject.toml` or `requirements.txt`, it only sets up `uv`.
+You should run `uv sync` or `uv pip install .` separately, or use `uv run ...` to ensure necessary dependencies are installed.
+
+### Why is a changed cache not detected and not the full cache uploaded?
+
+When `setup-uv` starts it has to know whether it is better to download an existing cache
+or start fresh and download every dependency again.
+It does this by using a combination of hashes calculated on the contents of e.g. `uv.lock`.
+
+By calculating these hashes and combining them in a key `setup-uv` can check
+if an uploaded cache exists for this key.
+If yes (e.g. contents of `uv.lock` did not change since last run) the dependencies in the cache
+are up to date and the cache will be downloaded and used.
+
+Details on determining which files will lead to different caches can be read in the
+[Caching documentation](docs/caching.md).
+
+Some dependencies will never be uploaded to the cache and will be downloaded again on each run
+as described in the [Caching documentation](docs/caching.md).

+# Advanced Version Configuration
+
+This document covers advanced options for configuring which version of uv to install.
+
+## Install the latest version
+
+```yaml
+- name: Install the latest version of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: "latest"
+```
+
+## Install a specific version
+
+```yaml
+- name: Install a specific version of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: "0.4.4"
+```
+
+## Install a version by supplying a semver range or pep440 specifier
+
+You can specify a [semver range](https://github.com/npm/node-semver?tab=readme-ov-file#ranges)
+or [pep440 specifier](https://peps.python.org/pep-0440/#version-specifiers)
+to install the latest version that satisfies the range.
+
+```yaml
+- name: Install a semver range of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: ">=0.4.0"
+```
+
+```yaml
+- name: Pinning a minor version of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: "0.4.x"
+```
+
+```yaml
+- name: Install a pep440-specifier-satisfying version of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: ">=0.4.25,<0.5"
+```
+
+## Resolution strategy
+
+By default, when resolving version ranges, setup-uv will install the highest compatible version.
+You can change this behavior using the `resolution-strategy` input:
+
+```yaml
+- name: Install the lowest compatible version of uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: ">=0.4.0"
+    resolution-strategy: "lowest"
+```
+
+The supported resolution strategies are:
+- `highest` (default): Install the latest version that satisfies the constraints
+- `lowest`: Install the oldest version that satisfies the constraints
+
+This can be useful for testing compatibility with older versions of uv, similar to uv's own `--resolution-strategy` option.
+
+## Install a version defined in a requirements or config file
+
+You can use the `version-file` input to specify a file that contains the version of uv to install.
+This can either be a `pyproject.toml` or `uv.toml` file which defines a `required-version` or
+uv defined as a dependency in `pyproject.toml` or `requirements.txt`.
+
+[asdf](https://asdf-vm.com/) `.tool-versions` is also supported, but without the `ref` syntax.
+
+```yaml
+- name: Install uv based on the version defined in pyproject.toml
+  uses: astral-sh/setup-uv@v7
+  with:
+    version-file: "pyproject.toml"
+```

+# Caching
+
+This document covers all caching-related configuration options for setup-uv.
+
+## Cache key
+
+The cache key is automatically generated based on:
+
+- **Architecture**: CPU architecture (e.g., `x86_64`, `aarch64`)
+- **Platform**: OS platform type (e.g., `unknown-linux-gnu`, `unknown-linux-musl`, `apple-darwin`,
+  `pc-windows-msvc`)
+- **OS version**: OS name and version (e.g., `ubuntu-22.04`, `macos-14`, `windows-2022`)
+- **Python version**: The Python version in use
+- **Cache options**: Whether pruning and Python caching are enabled
+- **Dependency hash**: Hash of files matching `cache-dependency-glob`
+- **Suffix**: Optional `cache-suffix` if provided
+
+Including the OS version ensures that caches are not shared between different OS versions,
+preventing binary incompatibility issues when runner images change.
+
+The computed cache key is available as the `cache-key` output:
+
+```yaml
+- name: Setup uv
+  id: setup-uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+- name: Print cache key
+  run: echo "Cache key: ${{ steps.setup-uv.outputs.cache-key }}"
+```
+
+## Enable caching
+
+> [!NOTE]
+> The cache is pruned before it is uploaded to the GitHub Actions cache. This can lead to
+> a small or empty cache. See [Disable cache pruning](#disable-cache-pruning) for more details.
+
+If you enable caching, the [uv cache](https://docs.astral.sh/uv/concepts/cache/) will be uploaded to
+the GitHub Actions cache. This can speed up runs that reuse the cache by several minutes.
+Caching is enabled by default on GitHub-hosted runners.
+
+> [!TIP]
+>
+> On self-hosted runners this is usually not needed since the cache generated by uv on the runner's
+> filesystem is not removed after a run. For more details see [Local cache path](#local-cache-path).
+
+You can optionally define a custom cache key suffix.
+
+```yaml
+- name: Enable caching and define a custom cache key suffix
+  id: setup-uv
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-suffix: "optional-suffix"
+```
+
+When the cache was successfully restored, the output `cache-hit` will be set to `true` and you can
+use it in subsequent steps. For example, to use the cache in the above case:
+
+```yaml
+- name: Do something if the cache was restored
+  if: steps.setup-uv.outputs.cache-hit == 'true'
+  run: echo "Cache was restored"
+```
+
+## Cache dependency glob
+
+If you want to control when the GitHub Actions cache is invalidated, specify a glob pattern with the
+`cache-dependency-glob` input. The GitHub Actions cache will be invalidated if any file matching the glob pattern
+changes. If you use relative paths, they are relative to the working directory.
+
+> [!NOTE]
+>
+> You can look up supported patterns [here](https://github.com/actions/toolkit/tree/main/packages/glob#patterns)
+>
+> The default is
+> ```yaml
+> cache-dependency-glob: |
+>   **/*requirements*.txt
+>   **/*requirements*.in
+>   **/*constraints*.txt
+>   **/*constraints*.in
+>   **/pyproject.toml
+>   **/uv.lock
+>   **/*.py.lock
+> ```
+
+```yaml
+- name: Define a cache dependency glob
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-dependency-glob: "**/pyproject.toml"
+```
+
+```yaml
+- name: Define a list of cache dependency globs
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-dependency-glob: |
+      **/requirements*.txt
+      **/pyproject.toml
+```
+
+```yaml
+- name: Define an absolute cache dependency glob
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-dependency-glob: "/tmp/my-folder/requirements*.txt"
+```
+
+```yaml
+- name: Never invalidate the cache
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-dependency-glob: ""
+```
+
+## Restore cache
+
+Restoring an existing cache can be enabled or disabled with the `restore-cache` input.
+By default, the cache will be restored.
+
+```yaml
+- name: Don't restore an existing cache
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    restore-cache: false
+```
+
+## Save cache
+
+You can also disable saving the cache after the run with the `save-cache` input.
+This can be useful to save cache storage when you know you will not use the cache of the run again.
+By default, the cache will be saved.
+
+```yaml
+- name: Don't save the cache after the run
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    save-cache: false
+```
+
+## Local cache path
+
+If caching is enabled, this action controls where uv stores its cache on the runner's filesystem
+by setting `UV_CACHE_DIR`.
+
+It defaults to `setup-uv-cache` in the `TMP` dir, `D:\a\_temp\setup-uv-cache` on Windows and
+`/tmp/setup-uv-cache` on Linux/macOS. You can change the default by specifying the path with the
+`cache-local-path` input.
+
+> [!NOTE]
+> If the environment variable `UV_CACHE_DIR` is already set this action will not override it.
+> If you configured [cache-dir](https://docs.astral.sh/uv/reference/settings/#cache-dir) in your
+> config file then it is also respected and this action will not set `UV_CACHE_DIR`.
+
+> [!NOTE]
+> If caching is disabled, you can still use `cache-local-path` so this action sets `UV_CACHE_DIR`
+> to your desired path.
+
+```yaml
+- name: Define a custom uv cache path
+  uses: astral-sh/setup-uv@v7
+  with:
+    cache-local-path: "/path/to/cache"
+```
+
+## Disable cache pruning
+
+By default, the uv cache is pruned after every run, removing pre-built wheels, but retaining any
+wheels that were built from source. On GitHub-hosted runners, it's typically faster to omit those
+pre-built wheels from the cache (and instead re-download them from the registry on each run).
+However, on self-hosted or local runners, preserving the cache may be more efficient. See
+the [documentation](https://docs.astral.sh/uv/concepts/cache/#caching-in-continuous-integration) for
+more information.
+
+If you want to persist the entire cache across runs, disable cache pruning with the `prune-cache`
+input.
+
+```yaml
+- name: Don't prune the cache before saving it
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    prune-cache: false
+```
+
+## Cache Python installs
+
+By default, the Python install dir (`uv python dir` / `UV_PYTHON_INSTALL_DIR`) is not cached,
+for the same reason that the dependency cache is pruned.
+If you want to cache Python installs along with your dependencies, set the `cache-python` input to `true`.
+
+Note that this only caches Python versions that uv actually installs into `UV_PYTHON_INSTALL_DIR`
+(i.e. managed Python installs). If uv uses a system Python, there may be nothing to cache.
+To force managed Python installs, set `UV_PYTHON_PREFERENCE=only-managed`.
+
+```yaml
+- name: Cache Python installs
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    cache-python: true
+```
+
+## Ignore nothing to cache
+
+By default, the action will fail if caching is enabled but there is nothing to upload (the uv cache directory does not exist).
+If you want to ignore this, set the `ignore-nothing-to-cache` input to `true`.
+
+```yaml
+- name: Ignore nothing to cache
+  uses: astral-sh/setup-uv@v7
+  with:
+    enable-cache: true
+    ignore-nothing-to-cache: true
+```

+# Customization
+
+This document covers advanced customization options including checksum validation, custom manifests, and problem matchers.
+
+## Validate checksum
+
+You can specify a checksum to validate the downloaded executable. Checksums up to the default version
+are automatically verified by this action. The sha256 hashes can be found on the
+[releases page](https://github.com/astral-sh/uv/releases) of the uv repo.
+
+```yaml
+- name: Install a specific version and validate the checksum
+  uses: astral-sh/setup-uv@v7
+  with:
+    version: "0.3.1"
+    checksum: "e11b01402ab645392c7ad6044db63d37e4fd1e745e015306993b07695ea5f9f8"
+```
+
+## Manifest file
+
+By default, setup-uv reads version metadata from
+[`astral-sh/versions`](https://github.com/astral-sh/versions).
+
+The `manifest-file` input lets you override that source with your own URL, for example to test
+custom uv builds or alternate download locations.
+
+### Format
+
+The manifest file must use the same format as `astral-sh/versions`: one JSON object per line, where each object represents a version and its artifacts. The versions must be sorted in descending order. For example:
+
+```json
+{"version":"0.10.7","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
+{"version":"0.10.6","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
+```
+
+setup-uv currently only supports `default` as the `variant`.
+
+The `archive_format` field is currently ignored.
+
+```yaml
+- name: Use a custom manifest file
+  uses: astral-sh/setup-uv@v7
+  with:
+    manifest-file: "https://example.com/my-custom-manifest.ndjson"
+```
+
+> [!NOTE]
+> When you use a custom manifest file and do not set the `version` input, setup-uv installs the
+> latest version from that custom manifest.
+
+## Add problem matchers
+
+This action automatically adds
+[problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md)
+for python errors.
+
+You can disable this by setting the `add-problem-matchers` input to `false`.
+
+```yaml
+- name: Install the latest version of uv without problem matchers
+  uses: astral-sh/setup-uv@v7
+  with:
+    add-problem-matchers: false

+# Environment and Tools
+
+This document covers environment activation, tool directory configuration, and authentication options.
+
+## Activate environment
+
+You can set `activate-environment` to `true` to automatically activate a venv.
+This allows directly using it in later steps:
+
+```yaml
+- name: Install the latest version of uv and activate the environment
+  uses: astral-sh/setup-uv@v7
+  with:
+    activate-environment: true
+- run: uv pip install pip
+```
+
+By default, the venv is created at `.venv` inside the `working-directory`.
+
+You can customize the venv location with `venv-path`, for example to place it in the runner temp directory:
+
+```yaml
+- uses: astral-sh/setup-uv@v7
+  with:
+    activate-environment: true
+    venv-path: ${{ runner.temp }}/custom-venv
+```
+
+> [!WARNING]
+>
+> Activating the environment adds your dependencies to the `PATH`, which could break some workflows.
+> For example, if you have a dependency which requires uv, e.g., `hatch`, activating the
+> environment will shadow the `uv` binary installed by this action and may result in a different uv
+> version being used.
+>
+> We do not recommend using this setting for most use-cases. Instead, use `uv run` to execute
+> commands in the environment.
+
+## GitHub authentication token
+
+By default, this action resolves available uv versions from
+[`astral-sh/versions`](https://github.com/astral-sh/versions), then downloads uv artifacts from
+GitHub Releases.
+
+You can provide a token via `github-token` to authenticate those downloads. By default, the
+`GITHUB_TOKEN` secret is used, which is automatically provided by GitHub Actions.
+
+If the default
+[permissions for the GitHub token](https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
+are not sufficient, you can provide a custom GitHub token with the necessary permissions.
+
+```yaml
+- name: Install the latest version of uv with a custom GitHub token
+  uses: astral-sh/setup-uv@v7
+  with:
+    github-token: ${{ secrets.CUSTOM_GITHUB_TOKEN }}
+```
+
+## UV_TOOL_DIR
+
+On Windows `UV_TOOL_DIR` is set to `uv-tool-dir` in the `TMP` dir (e.g. `D:\a\_temp\uv-tool-dir`).
+On GitHub hosted runners this is on the much faster `D:` drive.
+
+On all other platforms the tool environments are placed in the
+[default location](https://docs.astral.sh/uv/concepts/tools/#tools-directory).
+
+If you want to change this behaviour (especially on self-hosted runners) you can use the `tool-dir`
+input:
+
+```yaml
+- name: Install the latest version of uv with a custom tool dir
+  uses: astral-sh/setup-uv@v7
+  with:
+    tool-dir: "/path/to/tool/dir"
+```
+
+## UV_TOOL_BIN_DIR
+
+On Windows `UV_TOOL_BIN_DIR` is set to `uv-tool-bin-dir` in the `TMP` dir (e.g.
+`D:\a\_temp\uv-tool-bin-dir`). On GitHub hosted runners this is on the much faster `D:` drive. This
+path is also automatically added to the PATH.
+
+On all other platforms the tool binaries get installed to the
+[default location](https://docs.astral.sh/uv/concepts/tools/#the-bin-directory).
+
+If you want to change this behaviour (especially on self-hosted runners) you can use the
+`tool-bin-dir` input:
+
+```yaml
+- name: Install the latest version of uv with a custom tool bin dir
+  uses: astral-sh/setup-uv@v7
+  with:
+    tool-bin-dir: "/path/to/tool-bin/dir"
+```
+
+## Tilde Expansion
+
+This action supports expanding the `~` character to the user's home directory for the following inputs:
+
+- `version-file`
+- `cache-local-path`
+- `tool-dir`
+- `tool-bin-dir`
+- `cache-dependency-glob`
+
+```yaml
+- name: Expand the tilde character
+  uses: astral-sh/setup-uv@v7
+  with:
+    cache-local-path: "~/path/to/cache"
+    tool-dir: "~/path/to/tool/dir"
+    tool-bin-dir: "~/path/to/tool-bin/dir"
+    cache-dependency-glob: "~/my-cache-buster"
+```
+
+## Ignore empty workdir
+
+By default, the action will warn if the workdir is empty, because this is usually the case when
+`actions/checkout` is configured to run after `setup-uv`, which is not supported.
+
+If you want to ignore this, set the `ignore-empty-workdir` input to `true`.
+
+```yaml
+- name: Ignore empty workdir
+  uses: astral-sh/setup-uv@v7
+  with:
+    ignore-empty-workdir: true
+```
+
+## Environment Variables
+
+This action sets several environment variables that influence uv's behavior and can be used by subsequent steps:
+
+- `UV_PYTHON`: Set when `python-version` input is specified. Controls which Python version uv uses.
+- `UV_CACHE_DIR`: Set when caching is enabled (unless already configured in uv config files). Controls where uv stores its cache.
+- `UV_TOOL_DIR`: Set when `tool-dir` input is specified. Controls where uv installs tool environments.
+- `UV_TOOL_BIN_DIR`: Set when `tool-bin-dir` input is specified. Controls where uv installs tool binaries.
+- `UV_PYTHON_INSTALL_DIR`: Always set. Controls where uv installs Python versions.
+- `VIRTUAL_ENV`: Set when `activate-environment` is true. Points to the activated virtual environment.
+
+**Environment variables that affect the action behavior:**
+
+- `UV_NO_MODIFY_PATH`: If set, prevents the action from modifying PATH. Cannot be used with `activate-environment`.
+- `UV_CACHE_DIR`: If already set, the action will respect it instead of setting its own cache directory.
+
+```yaml
+- name: Example using environment variables
