actions/checkout default fetch-depth 1 merge commit parent history git show documentation
💡 Result:
The actions/checkout action has a default fetch-depth of 1, which performs a shallow clone by fetching only the single commit that triggered the workflow [1][2]. Key aspects of this default behavior include: 1. Limited History: Because only one commit is fetched, the local Git repository will not contain the parent history of that commit [1][3]. Attempting to access parent commits or perform operations that require the commit graph (like certain git log or merge-base commands) will fail unless you increase the fetch-depth [3][4]. 2. Merge Commit Default: For pull request events, the default reference (ref) checked out by actions/checkout is a generated test merge commit (the PR merged into the base branch) [4][5]. This is done to test the PR changes in the context of the base branch [5]. 3. Impact on Git Operations: If you require full access to commit history, tags, or the ability to determine common ancestors (e.g., for calculating diffs or semantic versioning), you must explicitly configure the action [6][4]: - To fetch all history (including all branches and tags), set fetch-depth: 0 [1][7]. - To fetch a specific number of commits (e.g., to support merging or finding merge-bases), set fetch-depth to an appropriate integer (e.g., 2 or more) [1][3][4]. - If tags are required but you do not need the full commit history, you can set fetch-tags: true [2][8]. In summary, the default fetch-depth: 1 is an optimization for performance and speed, assuming you only need to work with the files at the specific ref that triggered the build [6][5]. For workflows requiring deeper Git knowledge, you must override these defaults in your workflow YAML configuration [1][6].

Fetch the merge parents before running the skill.
The default fetch-depth: 1 does not provide the merge commit’s parent history. git show* cannot reliably calculate the merged PR diff without those parent objects. Set fetch-depth: 0.

Claude Code plugin_marketplaces repository default branch ref syntax GitHub URL commit SHA
💡 Result:
In Claude Code, the configuration for plugin marketplaces and plugins supports version pinning using a ref field [1][2]. The following details clarify the syntax and behavior for repository references: Default Branch Behavior By default, if the ref field is omitted in a plugin or marketplace source configuration, Claude Code automatically defaults to the repository's configured default branch [1][3]. Ref Syntax The ref field is a string that accepts a Git branch name, tag, or commit SHA [3]. When using the shorthand GitHub repository syntax (owner/repo), you can also append @ref to pin to a specific branch or tag directly [2]. Commit SHA Pinning For exact version control, the sha field can be used in conjunction with ref [1][2]. The sha field requires a full 40-character git commit SHA [1][3]. When both ref and sha are provided, the sha acts as the effective pin, and Claude Code fetches the specified commit directly [1]. Example Configurations For a GitHub repository source defined in a configuration (such as settings.json or marketplace manifests), the structure is as follows [1][2]: { "name": "example-plugin", "source": { "source": "github", "repo": "owner/plugin-repo", "ref": "v1.0.0", "sha": "a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0" } } When adding a marketplace via the command line, the shorthand syntax is also supported: /plugin marketplace add owner/repo@ref Note that while these fields control plugin and marketplace sources, Claude Code's internal detection of a repository's "default branch" for other operations (like diffs or PR creation) may sometimes rely on local Git metadata (refs/remotes/origin/HEAD) or specific fallbacks, which can differ from these explicit marketplace configuration settings [4][5][6].

npm npx -y package without version resolves latest dist-tag documentation
💡 Result:
When you run npx without specifying a version, it does not strictly resolve to the latest dist-tag. Instead, npm's resolution logic prioritizes compatibility with your current Node.js runtime environment based on the package's engines field [1][2]. The resolution behavior is as follows: 1. Compatibility Prioritization: Since mid-2024, npm prioritizes versions whose engines field matches your installed Node.js version [1]. If the version pointed to by the latest dist-tag is incompatible with your Node.js runtime, npm will automatically search for the newest version that satisfies your environment's requirements instead [1][2]. 2. Pre-existing Installations: If the requested package is already available in your local project's node_modules or in your system's PATH, npx will use that existing version rather than fetching a new one [3][4][5]. This prevents npx from unnecessarily updating packages that are already present in your environment [6][5]. 3. Registry Interaction: When the package is not found locally, npx fetches the package from the registry. While it generally aims to provide the latest appropriate version, the inclusion of engine constraints means the resolved version may be older than the official latest tag if that newer version is incompatible with your machine's Node.js version [1][2]. If you explicitly require the latest version regardless of engine compatibility or local installation status, you should use the @latest tag (e.g., npx package@latest), which forces npm to fetch that specific version [2][6][5].

GitHub Actions pin third-party actions to full length commit SHA official documentation
💡 Result:
GitHub strongly recommends pinning third-party actions to a full-length (40-character) commit SHA to ensure security and stability [1][2][3]. This practice makes the action reference immutable, meaning the workflow will always execute the exact code you reviewed and approved, regardless of any upstream changes to tags or branches [1][4][5][6]. Key points regarding this practice: Security and Immutability: Pinning to a full-length SHA is the only way to treat an action as an immutable release [1][3]. While version tags (e.g., @v3) are convenient, they are mutable references that can be moved or deleted by a repository owner or an attacker who gains unauthorized access to the action's repository [1][7][5]. Using a full-length SHA mitigates the risk of supply chain attacks, such as backdoored code being injected into an action version you are already using [1][3]. Avoid Shortened SHAs: You must use the full 40-character commit SHA [6][8]. Shortened commit SHAs are considered insecure because they are vulnerable to collisions; an attacker could potentially create a crafted commit in a forked repository that conflicts with the shortened SHA, causing your workflows to fail or behave unpredictably [3]. Policy Enforcement: GitHub allows administrators to enforce this security practice at both the organization and repository levels [1][9][10]. When the "Require actions to be pinned to a full-length commit SHA" policy is enabled, workflows that attempt to use actions pinned to tags or branches will fail, ensuring that all third-party components meet the specified security standard [9][10]. Maintenance: Because pinning to a SHA prevents your workflow from automatically receiving updates (including security patches), it is recommended to use automation tools like Dependabot to keep these pinned dependencies up to date [7][4][11]. A common practice is to include the human-readable version tag as a comment on the same line in your workflow file, which allows Dependabot to track and propose updates to the next release [7].

site:code.claude.com/docs plugin_marketplaces Claude Code action input URL ref sha
💡 Result:
In Claude Code, the terms ref and sha are used to manage version control and pinning for git-based plugin marketplaces [1]. When configuring a git-based marketplace—such as those using the github, url, or git-subdir source types—you can use the following parameters to target specific versions [1]: - ref: Specifies a git branch or tag (defaults to the repository's default branch if omitted) [1]. - sha: Specifies the full 40-character git commit SHA to pin the plugin to an exact version [1]. If both ref and sha are provided, the sha is treated as the effective pin, and Claude Code will fetch and check out that specific commit [1]. In the context of the Claude Code GitHub Action, the plugin_marketplaces input accepts a newline-separated list of Git repository URLs [2][3]. While you specify the URL in the action input, standard Claude Code marketplace syntax allows you to append these versioning qualifiers to the source definition (e.g., using #ref to specify a branch or tag in a URL) [1][4]. For pinning to an exact commit in a marketplace catalog, the plugins themselves are managed via their entries in the marketplace.json manifest, where specific versions can be pinned by commit SHA [1][5][6].

Pin action and plugin dependencies to immutable versions.
actions/checkout@v4 and anthropics/claude-code-action@v1 use mutable tags. The marketplace URL follows its default branch when no ref is set. Pin both actions to full commit SHAs. Pin the plugin source in the marketplace manifest to a full commit SHA. Pin @notionhq/notion-mcp-server to an approved exact package version.
Claude Code does not support a SHA for the marketplace source itself, so use only its supported fixed ref there.
