	<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.

<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-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>
