docs: cover Python dependency updates - #41
Conversation
📝 WalkthroughWalkthroughThe dependency update skill now covers Python/uv dependency discovery, inventory, targeted lockfile updates, frozen synchronisation, and validation for lock consistency and native/GPU compatibility. ChangesPython/uv dependency management
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The workflow documentation could cause incorrect updates for private or non-PyPI dependencies and could leave the lockfile inconsistent with direct constraint changes, leading to misleading validation or broken dependency states. These bounded correctness issues should be fixed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 77-79: Update the dependency-audit instructions to resolve each
direct dependency’s configured source before querying release metadata: use PyPI
only for PyPI-backed packages, and use the matching tool.uv.sources or
[[tool.uv.index]] configuration for private-index, Git, URL, path, and workspace
dependencies. Preserve the existing comparison of declared constraints against
authoritative metadata.
- Around line 148-153: Update the uv dependency workflow instructions so direct
constraint edits in pyproject.toml occur before running uv lock; then regenerate
the lockfile for only the planned packages and run uv sync --frozen against the
updated lockfile.

site:docs.astral.sh/uv concepts projects dependencies tool.uv.sources indexes package metadata uv tree outdated
💡 Result:
In uv, projects are managed using pyproject.toml, which defines dependencies and project configuration [1][2][3]. Dependencies are specified in tables like project.dependencies (published packages) and dependency-groups (development dependencies) [1]. Key concepts and tools include: tool.uv.sources: This table extends standard dependency tables to provide alternative sources for packages during development, such as Git repositories, URLs, local paths, or specific package indexes [4][1]. These sources are respected exclusively by uv and are not used by other tools [1]. Indexes: By default, uv uses PyPI [5]. You can configure additional or private package indexes via the [[tool.uv.index]] setting in pyproject.toml [4][5]. Packages can be pinned to a specific index within tool.uv.sources, or an index can be marked as explicit = true to restrict it from being used unless explicitly pinned [1][5]. Package Metadata: During resolution, uv uses static metadata from indexes [6]. For packages where this is missing or incorrect—particularly those requiring builds—the tool.uv.dependency-metadata table allows you to provide static metadata upfront to bypass build-time resolution issues [7][6]. uv tree: This command displays the project's dependency tree, showing how dependencies are resolved [8][9][10]. It automatically ensures the lockfile and environment are up-to-date before running [2]. Outdated Packages: To manage updates, you can use uv lock --upgrade to update the entire lockfile or --upgrade-package to target specific packages for upgrade [3]. While there is no single "uv outdated" command, uv's workflow centers on keeping the environment and lockfile in sync with the pyproject.toml definitions [2][3]. top_results: [4][1][7][5][6][2][3]

site:docs.astral.sh/uv "uv sync --frozen" pyproject.toml lockfile dependency changes
💡 Result:
When you run uv sync --frozen, uv uses the existing lockfile as the single source of truth for the project's dependencies and will not attempt to update it, even if there are changes to your pyproject.toml [1][2]. Key behaviors of the --frozen flag include: 1. No Lockfile Updates: uv will not perform any dependency resolution or modify the uv.lock file [1][2]. If you have added, removed, or changed version constraints in your pyproject.toml, those changes will not be reflected in the lockfile or the environment [1][3]. 2. Environment Syncing: While the environment will still be synchronized to match the current lockfile, it will ignore any discrepancies between the pyproject.toml and the lockfile [1][3]. 3. Error Handling: If the lockfile is missing, uv will exit with an error because it cannot proceed without a source of truth [1]. 4. Consistency: This flag is primarily used for reproducible builds in environments like CI/CD pipelines, ensuring that the environment is created exactly as defined in the lockfile without external interference [3][4]. If you need to ensure the lockfile is up-to-date with your pyproject.toml instead of using a frozen state, you should omit the --frozen flag, which allows uv to automatically detect discrepancies and update the lockfile [3][4].

site:docs.astral.sh/uv "uv lock --upgrade-package" project dependency
💡 Result:
To upgrade a specific package in your project using uv, use the --upgrade-package flag with the uv lock command [1][2]. This will update the specified package to the latest version allowed by your project's dependency constraints while leaving other locked dependencies unchanged [1][2]. Basic usage: $ uv lock --upgrade-package You can also upgrade a package to a specific version: $ uv lock --upgrade-package == The --upgrade-package flag is also compatible with other project commands like uv sync and uv run, which will update both the lockfile and your environment [1][3]. Note that all upgrades remain constrained by the requirements defined in your pyproject.toml (e.g., version bounds) [1][3].

Move the direct-constraint edit before uv lock. If pyproject.toml changes, uv sync --frozen uses the existing uv.lock and ignores dependency changes that are not locked.
