+# CLI Description Standards for Kubebuilder
+
+Use this skill to write, review, or normalize Kubebuilder CLI command descriptions, flag help text, and examples.
+
+## Workflow
+
+1. Identify the CLI element:
+   - boolean flag
+   - value flag
+   - command short description
+   - command long description
+   - examples/help text
+2. Apply the matching standard below.
+3. Rewrite the text to match the standard.
+4. If reviewing, explain the issue briefly and propose the corrected wording.
+
+## Core principles
+
+- Prefer clarity over brevity.
+- Use consistent patterns across similar flags and commands.
+- Include examples, defaults, or fallback behavior when useful.
+- Tell users what happens when they use the flag.
+
+## Boolean flags
+
+### Default false (opt-in behavior)
+
+Use this pattern:
+
+```
+If set, <what happens>
+```
+
+Examples:
+
+- `If set, enable multigroup layout (organize APIs by group)`
+- `If set, skip Go version check`
+- `If set, attempt to create resource even if it already exists`
+
+### Default true (opt-out behavior)
+
+When a boolean flag defaults to `true`, describe the behavior and how to disable it:
+
+```
+<what happens by default>; use --flag=false to <opposite behavior>
+```
+
+Or for flags with more context:
+
+```
+<what happens> (enabled by default; use --flag=false to disable)
+```
+
+Examples:
+
+- `Run 'make generate' after generating files (enabled by default; use --make=false to disable)`
+- `Run 'make manifests' after generating files (enabled by default; use --manifests=false to disable)`
+- `Resource is namespaced by default; use --namespaced=false to create a cluster-scoped resource`
+- `Generate the resource without prompting the user (enabled by default; use --resource=false to disable)`
+- `Download dependencies after scaffolding (enabled by default; use --fetch-deps=false to disable)`
+
+### Tri-state (enable/disable/preserve)
+
+When a boolean flag preserves existing values if not provided, and supports both enabling and disabling:
+
+```
+Enable or disable <what>; use --flag=false to disable
+```
+
+Examples:
+
+- `Enable or disable multigroup layout (organize APIs by group); use --multigroup=false to disable`
+- `Enable or disable namespace-scoped deployment (default: cluster-scoped); use --namespaced=false to disable`
+
+### Prompting flags
+
+When a flag controls prompting behavior (prompts by default, but accepts explicit true/false to skip the prompt):
+
+```
+Prompt whether to <action> by default; use --flag=true or --flag=false to skip the prompt
+```
+
+Examples:
+
+- `Prompt whether to generate the controller by default; use --controller=true or --controller=false to skip the prompt`
+
+## Value flags
+
+Use these patterns:
+
+With an example:
+```
+<what> (e.g., <example>)
+```
+
+With a default:
+```
+<what> (e.g., <example>). Defaults to <default> if unset
+```
+
+With auto-detection:
+```
+<what> (e.g., <example>); auto-detected <method> if not provided
+```
+
+Examples:
+
+- `Go module name (e.g., github.com/user/repo); auto-detected from current directory if not provided`
+- `License header to use for boilerplate (e.g., apache2, none). Defaults to apache2 if unset`
+- `Project version (e.g., 3). Defaults to CLI version if unset`
+- `Domain for your APIs (e.g., example.org creates crew.example.org for API groups)`
+
+## Optional value flags
+
+When a flag is optional and modifies behavior, use:
+
+```
+[Optional] <what>. <additional context if useful> (e.g., <example>)
+```
+
+Examples:
+
+- `[Optional] Container command to use for image initialization (e.g., --image-container-command="memcached,--memory-limit=64,modern,-o,-v")`
+- `[Optional] Container port used by the container image (e.g., --image-container-port="11211")`
+
+## Path flags
+
+Use:
+
+```
+Path to <what>; <behavior> (e.g., <example>)
+```
+
+Example:
+
+- `Path to custom license file; content copied to hack/boilerplate.go.txt (overrides --license)`
+
+## List flags
+
+For comma-separated lists or arrays:
+
+```
+Comma-separated list of <what> (e.g., --flag value1,value2)
+```
+
+Example:
+
+- `Comma-separated list of spoke versions to be added to the conversion webhook (e.g., --spoke v1,v2)`
+
+## Deprecated flags
+
+For deprecated flags that will be removed in future versions:
+
+```
+[DEPRECATED] If set, <what it does>. This option will be removed in future versions
+```
+
+Example:
+
+- `[DEPRECATED] If set, attempts to create resource under the API directory (legacy path). This option will be removed in future versions`
+
+## Command short descriptions
+
+Rules:
+
+- Start with a capital letter.
+- Use a brief phrase or sentence.
+- Do not end with a period.
+- Prefer imperative wording.
+
+Examples:
+
+- `Initialize a new project`
+- `Scaffold a Kubernetes API`
+- `Scaffold a Kubernetes API or webhook`
+
+## Command long descriptions
+
+Long descriptions should:
+
+- explain what the command does
+- mention generated files or directories when relevant
+- separate required vs optional/configuration flags when helpful
+- use full sentences and punctuation
+- include behavioral notes when useful
+
+Use this structure when it fits:
+
+```
+Initialize a new project including the following files:
+  - a "go.mod" with project dependencies
+  - a "PROJECT" file that stores project configuration
+  - a "Makefile" with useful make targets
+
+Required flags:
+  --domain: Domain for your APIs (e.g., example.org creates crew.example.org for API groups)
+
+Configuration flags:
+  --repo: Go module name (e.g., github.com/user/repo); auto-detected from current directory if not provided
+
+Note: Layout settings can be changed later with 'kubebuilder edit'.
+```
+
+## Command examples
+
+Examples should:
+
+- be realistic and valid
+- progress from simple to complex
+- explain non-obvious cases
+- use the command name variable when writing Go examples
+
+Example:
+
+```go
+subcmdMeta.Examples = fmt.Sprintf(`  # Initialize a new project
+  %[1]s init --domain example.org
+
+  # Initialize with multigroup layout
+  %[1]s init --domain example.org --multigroup
+
+  # Initialize with all options combined
+  %[1]s init --plugins go/v4,autoupdate/v1-alpha --domain example.org --multigroup --namespaced
+`, cliMeta.CommandName)
+```
+
+## Common Kubebuilder flag wording
+
+Use these standard descriptions when applicable:
+
+- `--domain`: `Domain for your APIs (e.g., example.org creates crew.example.org for API groups)`
+- `--repo`: `Go module name (e.g., github.com/user/repo); auto-detected from current directory if not provided`
+- `--plugins`: `Comma-separated list of plugin keys to use (e.g., go/v4, helm/v2-alpha). Defaults to the built-in go/v4 bundle if unset`
+- `--multigroup`:
+  - In `init`: `If set, enable multigroup layout (organize APIs by group)`
+  - In `edit`: `Enable or disable multigroup layout (organize APIs by group); use --multigroup=false to disable`
+- `--skip-go-version-check`:
+  - When default is `false`: `If set, skip Go version check`
+  - When default is `true`: `Skip the Go version check (enabled by default; use --skip-go-version-check=false to enforce)`
+- `--force`: `If set, attempt to create resource even if it already exists` (or `If set, regenerate all files except Chart.yaml` for helm plugins)
+- `--license`:
+  - In `init`: `License header to use for boilerplate (e.g., apache2, none). Defaults to apache2 if unset`
+  - In `edit`: `License header to use for boilerplate (e.g., apache2, none). If unset, preserves the existing boilerplate`
+- `--owner`: `Owner name for copyright license headers`
+- `--namespaced`:
+  - In `api`: `Resource is namespaced by default; use --namespaced=false to create a cluster-scoped resource`
+  - In `edit`: `Enable or disable namespace-scoped deployment (default: cluster-scoped); use --namespaced=false to disable`
+- `--fetch-deps`: `Download dependencies after scaffolding (enabled by default; use --fetch-deps=false to disable)`
+- `--make`: `Run 'make generate' after generating files (enabled by default; use --make=false to disable)`
+- `--manifests`: `Run 'make manifests' after generating files (enabled by default; use --manifests=false to disable)`
+- `--resource`: `Generate the resource without prompting the user (enabled by default; use --resource=false to disable)`
+- `--controller`: `Prompt whether to generate the controller by default; use --controller=true or --controller=false to skip the prompt`
+
+## Review output pattern
+
+When reviewing, use this format:
+
+- **Issue**: one short sentence describing what is wrong
+- **Suggested text**: the corrected help text
+- **Reason**: one short sentence tying it back to the standard
+
+Example:
+
+- **Issue**: Boolean flag description does not describe the behavior when the flag is present.
+- **Suggested text**: `If set, enable multigroup layout (organize APIs by group)`
+- **Reason**: Boolean flags should follow the `If set, ...` pattern.
+
+## Checklist
+
+- [ ] Boolean flags that default to `false` use `If set, ...`
+- [ ] Boolean flags that default to `true` describe the behavior and how to disable (e.g., "enabled by default; use --flag=false to disable")
+- [ ] Value flags include examples with `(e.g., ...)`
+- [ ] List flags use `Comma-separated list of ...`
+- [ ] Deprecated flags are marked with `[DEPRECATED]`
+- [ ] Defaults are explicitly stated when they exist with "if unset" (e.g., "Defaults to X if unset")
+- [ ] Auto-detection or fallback behavior is documented
+- [ ] Short descriptions are capitalized and do not end with a period
+- [ ] Long descriptions are complete and organized
+- [ ] Examples are realistic and valid
+- [ ] Terminology is consistent across commands and plugins
+
+## Notes
+
+- Apply these standards across all Kubebuilder plugins.
+- Prefer consistency across the codebase over one-off wording choices.
+- When the same flag appears with equivalent semantics across plugins, use identical descriptions. When semantics differ (e.g., `--force` in `create`/`api`/`edit`, or `--license` in `init`/`edit`), document the per-command variant explicitly.
+- Flag descriptions should not end with a period (matches the `--help` convention used by cobra and the rest of Kubebuilder).
+- For multi-line flag descriptions in code, use string concatenation with `+` and break at natural boundaries (70-80 characters per line).
+- When in doubt, choose the wording that is clearest in `--help` output.
+- See [references/REFERENCE.md](references/REFERENCE.md) for technical references and industry standards that inform these guidelines.
