+
+# Create Next Version Branch
+
+Automate the creation of development branches and GitHub Release for a new GROWI version.
+
+## Input
+
+The argument `$ARGUMENTS` must be a branch name in the format `dev/{major}.{minor}.x` (e.g., `dev/7.5.x`).
+
+## Procedure
+
+### Step 1: Parse and Validate Input
+
+1. Parse `$ARGUMENTS` to extract `{major}` and `{minor}` from the `dev/{major}.{minor}.x` pattern
+2. If the format is invalid, display an error and stop:
+   - Must match `dev/{number}.{number}.x`
+3. Set the following variables:
+   - `DEV_BRANCH`: `dev/{major}.{minor}.x`
+   - `RELEASE_BRANCH`: `release/{major}.{minor}.x`
+   - `TAG_NAME`: `v{major}.{minor}.x-base`
+   - `RELEASE_TITLE`: `v{major}.{minor}.x Base Release`
+
+### Step 2: Create and Push the Development Branch
+
+1. Confirm with the user before proceeding
+2. Create and push `DEV_BRANCH` from the current HEAD:
+   ```bash
+   git checkout -b {DEV_BRANCH}
+   git push origin {DEV_BRANCH}
+   ```
+
+### Step 3: Create GitHub Release
+
+1. Create a GitHub Release using `gh release create`:
+   ```bash
+   gh release create {TAG_NAME} \
+     --target {DEV_BRANCH} \
+     --title "{RELEASE_TITLE}" \
+     --notes "The base release for release-drafter to avoid \`Error: GraphQL Rate Limit Exceeded\`
+   https://github.com/release-drafter/release-drafter/issues/1018" \
+     --latest=false \
+     --prerelease=false
+   ```
+   - `--latest=false`: Do NOT set as latest release
+   - `--prerelease=false`: Do NOT set as pre-release
+
+### Step 4: Verify targetCommitish
+
+1. Run the following command and confirm that `targetCommitish` equals `DEV_BRANCH`:
+   ```bash
+   gh release view {TAG_NAME} --json targetCommitish
+   ```
+2. If `targetCommitish` does not match, display an error and stop
+
+### Step 5: Create and Push the Release Branch
+
+1. From the same commit (still on `DEV_BRANCH`), create and push `RELEASE_BRANCH`:
+   ```bash
+   git checkout -b {RELEASE_BRANCH}
+   git push origin {RELEASE_BRANCH}
+   ```
+
+### Step 6: Summary
+
+Display a summary of all created resources:
+
+```
+Created:
+  - Branch: {DEV_BRANCH} (pushed to origin)
+  - Branch: {RELEASE_BRANCH} (pushed to origin)
+  - GitHub Release: {RELEASE_TITLE} (tag: {TAG_NAME}, target: {DEV_BRANCH})
+```
+
+## Error Handling
+
+- If `DEV_BRANCH` already exists on the remote, warn the user and ask how to proceed
+- If `RELEASE_BRANCH` already exists on the remote, warn the user and ask how to proceed
+- If the tag `TAG_NAME` already exists, warn the user and ask how to proceed
+- If `gh` CLI is not authenticated, instruct the user to run `gh auth login`
