	<title>Git Flow Branch Creator</title>
	<description>This prompt analyzes your current git changes using git status and git diff (or git diff --cached), then intelligently determines the appropriate branch type according to the Git Flow branching model and creates a semantic branch name.</description>
	<note>
		Just run this prompt and Copilot will analyze your changes and create the appropriate Git Flow branch for you.
	</note>
</instructions>

Workflow

Follow these steps:

1. Run git status to review the current repository state and changed files.
2. Run git diff (for unstaged changes) or git diff --cached (for staged changes) to analyze the nature of changes.
3. Analyze the changes using the Git Flow Branch Analysis Framework below.
4. Determine the appropriate branch type based on the analysis.
5. Generate a semantic branch name following Git Flow conventions.
6. Create the branch and switch to it automatically.
7. Provide a summary of the analysis and next steps.

Analysis Process

<analysis-process>
	<step-1>
		<title>Change Nature Analysis</title>
		<description>Examine the types of files modified and the nature of changes</description>
		<criteria>
			<files-modified>Look at file extensions, directory structure, and purpose</files-modified>
			<change-scope>Determine if changes are additive, corrective, or preparatory</change-scope>
			<urgency-level>Assess if changes address critical issues or are developmental</urgency-level>
		</criteria>
	</step-1>

	<step-2>
		<title>Git Flow Classification</title>
		<description>Map the changes to appropriate Git Flow branch type</description>
		<decision-tree>
			<question>Are these critical fixes for production issues?</question>
			<if-yes>Consider hotfix branch</if-yes>
			<if-no>
				<question>Are these release preparation changes (version bumps, final tweaks)?</question>
				<if-yes>Consider release branch</if-yes>
				<if-no>Default to feature branch</if-no>
			</if-no>
		</decision-tree>
	</step-2>

	<step-3>
		<title>Branch Name Generation</title>
		<description>Create semantic, descriptive branch name</description>
		<guidelines>
			<use-kebab-case>Use lowercase with hyphens</use-kebab-case>
			<be-descriptive>Name should clearly indicate the purpose</be-descriptive>
			<include-context>Add ticket numbers or project context when available</include-context>
			<keep-concise>Avoid overly long names</keep-concise>
		</guidelines>
	</step-3>
</analysis-process>
