-# Security Policy
-
-## Reporting a Vulnerability
-
-The `cobra` maintainers take security issues seriously and
-we appreciate your efforts to _**responsibly**_ disclose your findings.
-We will make every effort to swiftly respond and address concerns.
-
-To report a security vulnerability:
-
-1. **DO NOT** create a public GitHub issue for the vulnerability!
-2. **DO NOT** create a public GitHub Pull Request with a fix for the vulnerability!
-3. Send an email to `cobra-security@googlegroups.com`.
-4. Include the following details in your report:
-   - Description of the vulnerability
-   - Steps to reproduce
-   - Potential impact of the vulnerability (to your downstream project, to the Go ecosystem, etc.)
-   - Any potential mitigations you've already identified
-5. Allow up to 7 days for an initial response.
-   You should receive an acknowledgment of your report and an estimated timeline for a fix.
-6. (Optional) If you have a fix and would like to contribute your patch, please work
-   directly with the maintainers via `cobra-security@googlegroups.com` to
-   coordinate pushing the patch to GitHub, cutting a new release, and disclosing the change.
-
-## Response Process
-
-When a security vulnerability report is received, the `cobra` maintainers will:
-
-1. Confirm receipt of the vulnerability report within 7 days.
-2. Assess the report to determine if it constitutes a security vulnerability.
-3. If confirmed, assign the vulnerability a severity level and create a timeline for addressing it.
-4. Develop and test a fix.
-5. Patch the vulnerability and make a new GitHub release: the maintainers will coordinate disclosure with the reporter.
-6. Create a new GitHub Security Advisory to inform the broader Go ecosystem
-
-## Disclosure Policy
-
-The `cobra` maintainers follow a coordinated disclosure process:
-
-1. Security vulnerabilities will be addressed as quickly as possible.
-2. A CVE (Common Vulnerabilities and Exposures) identifier will be requested for significant vulnerabilities
-   that are within `cobra` itself.
-3. Once a fix is ready, the maintainers will:
-   - Release a new version containing the fix.
-   - Update the security advisory with details about the vulnerability.
-   - Credit the reporter (unless they wish to remain anonymous).
-   - Credit the fixer (unless they wish to remain anonymous, this may be the same as the reporter).
-   - Announce the vulnerability through appropriate channels
-     (GitHub Security Advisory, mailing lists, GitHub Releases, etc.)
-
-## Supported Versions
-
-Security fixes will typically only be released for the most recent major release.
-
-## Upstream Security Issues
-
-`cobra` generally will not accept vulnerability reports that originate in upstream
-dependencies. I.e., if there is a problem in Go code that `cobra` depends on,
-it is best to engage that project's maintainers and owners.
-
-This security policy primarily pertains only to `cobra` itself but if you believe you've
-identified a problem that originates in an upstream dependency and is being widely
-distributed by `cobra`, please follow the disclosure procedure above: the `cobra`
-maintainers will work with you to determine the severity and ecosystem impact.
-
-## Security Updates and CVEs
-
-Information about known security vulnerabilities and CVEs affecting `cobra` will
-be published as GitHub Security Advisories at
-https://github.com/spf13/cobra/security/advisories.
-
-All users are encouraged to watch the repository and upgrade promptly when
-security releases are published.
-
-## `cobra` Security Best Practices for Users
-
-When using `cobra` in your CLIs, the `cobra` maintainers recommend the following:
-
-1. Always use the latest version of `cobra`.
-2. [Use Go modules](https://go.dev/blog/using-go-modules) for dependency management.
-3. Always use the latest possible version of Go.
-
-## Security Best Practices for Contributors
-
-When contributing to `cobra`:
-
-1. Be mindful of security implications when adding new features or modifying existing ones.
-2. Be aware of `cobra`'s extremely large reach: it is used in nearly every Go CLI
-   (like Kubernetes, Docker, Prometheus, etc. etc.)
-3. Write tests that explicitly cover edge cases and potential issues.
-4. If you discover a security issue while working on `cobra`, please report it
-   following the process above rather than opening a public pull request or issue that
-   addresses the vulnerability.
-5. Take personal sec-ops seriously and secure your GitHub account: use [two-factor authentication](https://docs.github.com/en/authentication/securing-your-account-with-two-factor-authentication-2fa),
-   [sign your commits with a GPG or SSH key](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification),
-   etc.
-
-## Acknowledgments
-
-The `cobra` maintainers would like to thank all security researchers and
-community members who help keep cobra, its users, and the entire Go ecosystem secure through responsible disclosures!!
-

 Active Help is a framework provided by Cobra which allows a program to define messages (hints, warnings, etc) that will be printed during program usage.  It aims to make it easier for your users to learn how to use your program.  If configured by the program, Active Help is printed when the user triggers shell completion.

-For example,
-
-```console
-$ helm repo add [tab]
+For example, 
+```
+bash-5.1$ helm repo add [tab]
 You must choose a name for the repo you are adding.

-$ bin/helm package [tab]
+bash-5.1$ bin/helm package [tab]
 Please specify the path to the chart to package

-$ bin/helm package [tab][tab]
+bash-5.1$ bin/helm package [tab][tab]
 bin/    internal/    scripts/    pkg/     testdata/
 ```

 **Hint**: A good place to use Active Help messages is when the normal completion system does not provide any suggestions. In such cases, Active Help nicely supplements the normal shell completions to guide the user in knowing what is expected by the program.
-
 ## Supported shells

 Active Help is currently only supported for the following shells:
- Bash (using [bash completion V2](completions/_index.md#bash-completion-v2) only). Note that bash 4.4 or higher is required for the prompt to appear when an Active Help message is printed.
+- Bash (using [bash completion V2](shell_completions.md#bash-completion-v2) only). Note that bash 4.4 or higher is required for the prompt to appear when an Active Help message is printed.
 - Zsh

 ## Adding Active Help messages

-As Active Help uses the shell completion system, the implementation of Active Help messages is done by enhancing custom dynamic completions.  If you are not familiar with dynamic completions, please refer to [Shell Completions](completions/_index.md).
+As Active Help uses the shell completion system, the implementation of Active Help messages is done by enhancing custom dynamic completions.  If you are not familiar with dynamic completions, please refer to [Shell Completions](shell_completions.md).

 The example above defines the completions (none, in this specific example) as well as the Active Help messages for the `helm repo add` command.  It yields the following behavior:
-
-```console
-$ helm repo add [tab]
+```
+bash-5.1$ helm repo add [tab]
 You must choose a name for the repo you are adding

-$ helm repo add grafana [tab]
+bash-5.1$ helm repo add grafana [tab]
 You must specify the URL for the repo you are adding

-$ helm repo add grafana https://grafana.github.io/helm-charts [tab]
+bash-5.1$ helm repo add grafana https://grafana.github.io/helm-charts [tab]
 This command does not take any more arguments
 ```

 **Hint**: As can be seen in the above example, a good place to use Active Help messages is when the normal completion system does not provide any suggestions. In such cases, Active Help nicely supplements the normal shell completions.

 ### Active Help for flags

 Providing Active Help for flags is done in the same fashion as for nouns, but using the completion function registered for the flag.  For example:
-
 ```go
-_ = cmd.RegisterFlagCompletionFunc("version", func(cmd *cobra.Command, args []string, toComplete string) ([]cobra.Completion, cobra.ShellCompDirective) {
+_ = cmd.RegisterFlagCompletionFunc("version", func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {

 		}

 The example above prints an Active Help message when not enough information was given by the user to complete the `--version` flag.
-
-```console
-$ bin/helm install myrelease --version 2.0.[tab]

+bash-5.1$ bin/helm install myrelease --version 2.0.[tab]
 You must first specify the chart to install before the --version flag can be completed

 **Note 1**: If the `<PROGRAM>_ACTIVE_HELP` environment variable is set to the string "0", Cobra will automatically disable all Active Help output (even if some output was specified by the program using the `cobra.AppendActiveHelp(...)` function).  Using "0" can simplify your code in situations where you want to blindly disable Active Help without having to call `cobra.GetActiveHelpConfig(cmd)` explicitly.

 **Note 2**: If a user wants to disable Active Help for every single program based on Cobra, she can set the environment variable `COBRA_ACTIVE_HELP` to "0".  In this case `cobra.GetActiveHelpConfig(cmd)` will return "0" no matter what the variable `<PROGRAM>_ACTIVE_HELP` is set to.

 **Note 3**: If the user does not set `<PROGRAM>_ACTIVE_HELP` or `COBRA_ACTIVE_HELP` (which will be a common case), the default value for the Active Help configuration returned by `cobra.GetActiveHelpConfig(cmd)` will be the empty string.

-### Organizing subcommands
-
-A command may have subcommands which in turn may have other subcommands. This is achieved by using
-`AddCommand`. In some cases, especially in larger applications, each subcommand may be defined in
-its own go package.
-
-The suggested approach is for the parent command to use `AddCommand` to add its most immediate
-subcommands. For example, consider the following directory structure:
-
-```console
-├── cmd
-│   ├── root.go
-│   └── sub1
-│       ├── sub1.go
-│       └── sub2
-│           ├── leafA.go
-│           ├── leafB.go
-│           └── sub2.go
-└── main.go
-```
-
-In this case:
-
-* The `init` function of `root.go` adds the command defined in `sub1.go` to the root command.
-* The `init` function of `sub1.go` adds the command defined in `sub2.go` to the sub1 command.
-* The `init` function of `sub2.go` adds the commands defined in `leafA.go` and `leafB.go` to the
-  sub2 command.
-
-This approach ensures the subcommands are always included at compile time while avoiding cyclic
-references.

-Cobra supports grouping of available commands in the help output.  To group commands, each group must be explicitly
-defined using `AddGroup()` on the parent command.  Then a subcommand can be added to a group using the `GroupID` element

-calls to `AddGroup()`.  If you use the generated `help` or `completion` commands, you can set their group ids using
-`SetHelpCommandGroupId()` and `SetCompletionCommandGroupId()` on the root command, respectively.
