-name: dependabot-pr-rollup
-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 Dependabot PRs can already be partially merged, superseded by newer versions, or have no remaining net effect.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.
-- Before finishing, make sure validation does not leave generated or formatting-only diffs behind.

 ## Usage
 
-### Install a required-version or latest (default)
+### Install the latest version (default)
 
 ```yaml
 - name: Install the latest version of uv
-  uses: astral-sh/setup-uv@v7
+  uses: astral-sh/setup-uv@v5
+  with:
+    version: "latest"
 ```
 
-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).

-## Advanced Configuration
+### Enable caching
 
-For more advanced configuration options, see our detailed documentation:
+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.
 
-- **[Advanced Version Configuration](docs/advanced-version-configuration.md)** - Resolution strategies and version files
+> [!TIP]
-- **[Caching](docs/caching.md)** - Complete guide to caching configuration
+>
-- **[Environment and Tools](docs/environment-and-tools.md)** - Environment activation, tool directories, authentication, and environment variables
+> On self-hosted runners this is usually not needed since the cache generated by uv on the runner's
-- **[Customization](docs/customization.md)** - Checksum validation, custom manifests, and problem matchers
+> 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@v5
+  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 repository root.
+
+> [!NOTE]
+>
+> The default is
+> ```yaml
+> cache-dependency-glob: |
+>   **/requirements*.txt
+>   **/uv.lock
+> ```
+
+```yaml
+- name: Define a cache dependency glob
+  uses: astral-sh/setup-uv@v5
+  with:
+    enable-cache: true
+    cache-dependency-glob: "**/pyproject.toml"
+```
+
+```yaml
+- name: Define a list of cache dependency globs
+  uses: astral-sh/setup-uv@v5
+  with:
+    enable-cache: true
+    cache-dependency-glob: |
+      **/requirements*.txt
+      **/pyproject.toml
+```
+
+```yaml
+- name: Define an absolute cache dependency glob
+  uses: astral-sh/setup-uv@v5
+  with:
+    enable-cache: true
+    cache-dependency-glob: "/tmp/my-folder/requirements*.txt"
+```
+
+```yaml
+- name: Never invalidate the cache
+  uses: astral-sh/setup-uv@v5
+  with:
+    enable-cache: true
+    cache-dependency-glob: ""
+```
+
+### Local cache path
+
+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\uv-tool-dir` 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.
+
+```yaml
+- name: Define a custom uv cache path
+  uses: astral-sh/setup-uv@v5
+  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@v5
+  with:
+    enable-cache: true
+    prune-cache: false
+```
+
+### 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@v5
+  with:
+    enable-cache: true
+    ignore-nothing-to-cache: true
+```
+
+### GitHub authentication token
+
+This action uses the GitHub API to fetch the uv release artifacts. To avoid hitting the GitHub API
+rate limit too quickly, an authentication token can be provided via the `github-token` input. 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@v5
+  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@v5
+  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@v5
+  with:
+    tool-bin-dir: "/path/to/tool-bin/dir"
+```

+This action supports expanding the `~` character to the user's home directory for the following inputs:
+
+- `cache-local-path`
+- `tool-dir`
+- `tool-bin-dir`
+- `cache-dependency-glob`
+
+```yaml

-### Should I include the resolution strategy in the cache key?
-
-**Yes!**
-
-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"
-```

docs/caching.md

@@ -1,225 +0,0 @@
-# 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) (NDJSON format).
-
-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 be in NDJSON format, where each line is a JSON object representing a version and its artifacts. 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.
-
-### Legacy format: JSON array (deprecated)
-
-The previous JSON array format is still supported for compatibility, but deprecated and will be
-removed in a future major release.
-
-```json
-[
-  {
-    "version": "0.7.13",
-    "artifactName": "uv-aarch64-apple-darwin.tar.gz",
-    "arch": "aarch64",
-    "platform": "apple-darwin",
-    "downloadUrl": "https://github.com/astral-sh/uv/releases/download/0.7.13/uv-aarch64-apple-darwin.tar.gz"
-  }
-]
-```
-
-```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
-  uses: astral-sh/setup-uv@v7
-  with:
-    python-version: "3.12"
-    tool-dir: "/custom/tool/dir"
-    enable-cache: true
-
-- name: Check environment variables
-  run: |
-    echo "UV_PYTHON: $UV_PYTHON"
-    echo "UV_CACHE_DIR: $UV_CACHE_DIR"
-    echo "UV_TOOL_DIR: $UV_TOOL_DIR"
-    echo "UV_PYTHON_INSTALL_DIR: $UV_PYTHON_INSTALL_DIR"
