-2. **Check for existing branches before creating new one**:
+2. **Create the feature branch** by running the script with `--short-name` (and `--json`). In sequential mode, do NOT pass `--number` — the script auto-detects the next available number. In timestamp mode, the script generates a `YYYYMMDD-HHMMSS` prefix automatically:
 
-   a. First, fetch all remote branches to ensure we have the latest information:
+   **Branch numbering mode**: Before running the script, check if `.specify/init-options.json` exists and read the `branch_numbering` value.
+   - If `"timestamp"`, add `--timestamp` (Bash) or `-Timestamp` (PowerShell) to the script invocation
+   - If `"sequential"` or absent, do not add any extra flag (default behavior)
 
-      ```bash
+   - Bash example: `.specify/scripts/bash/create-new-feature.sh "$ARGUMENTS" --json --short-name "user-auth" "Add user authentication"`
-      git fetch --all --prune
+   - Bash (timestamp): `.specify/scripts/bash/create-new-feature.sh "$ARGUMENTS" --json --timestamp --short-name "user-auth" "Add user authentication"`
-      ```

-
+   - PowerShell (timestamp): `.specify/scripts/bash/create-new-feature.sh "$ARGUMENTS" -Json -Timestamp -ShortName "user-auth" "Add user authentication"`
-   b. Find the highest feature number across all sources for the short-name:
-      - Remote branches: `git ls-remote --heads origin | grep -E 'refs/heads/[0-9]+-<short-name>$'`
-      - Local branches: `git branch | grep -E '^[* ]*[0-9]+-<short-name>$'`
-      - Specs directories: Check for directories matching `specs/[0-9]+-<short-name>`
-
-   c. Determine the next available number:
-      - Extract all numbers from all three sources
-      - Find the highest number N
-      - Use N+1 for the new branch number
-
-   d. Run the script `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS"` with the calculated number and short-name:
-      - Pass `--number N+1` and `--short-name "your-short-name"` along with the feature description
-      - Bash example: `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS" --json --number 5 --short-name "user-auth" "Add user authentication"`
-      - PowerShell example: `.specify/scripts/bash/create-new-feature.sh --json "$ARGUMENTS" -Json -Number 5 -ShortName "user-auth" "Add user authentication"`
 
    **IMPORTANT**:
-   - Check all three sources (remote branches, local branches, specs directories) to find the highest number
+   - Do NOT pass `--number` — the script determines the correct next number automatically
-   - Only match branches/directories with the exact short-name pattern
+   - Always include the JSON flag (`--json` for Bash, `-Json` for PowerShell) so the output can be parsed reliably
-   - If no existing branches/directories found with this short-name, start with number 1
    - You must only ever run this script once per feature
