 2. Read and analyze the feature specification to understand:
    - The feature requirements and user stories
    - Functional and non-functional requirements

 2. Load `templates/spec-template.md` to understand required sections.
 3. Write the specification to SPEC_FILE using the template structure, replacing placeholders with concrete details derived from the feature description (arguments) while preserving section order and headings.
 4. Report completion with branch name, spec file path, and readiness for the next phase.
