To merge delta specification changes without archiving, apply the delta specs directly to your main specification files to add, modify, remove, or rename requirements idempotently while preserving existing content.

Yes, applying delta specification changes to main specification files requires the openspec CLI, which reads both delta and main spec files to merge changes idempotently.

Update a feature spec from an active change branch by applying delta specifications through an intelligent merge that preserves existing content and scenarios while updating only the requested parts.

When you sync a delta spec into the main documents, existing requirements and content are preserved while only the parts requested by the delta are updated, preventing duplication or loss of prior scenarios.

Yes, you can partially add scenarios to a capability-level document because the intelligent merge process supports partial scenario additions alongside requirement modifications and renames.

To know which changes are available, you can prompt the workflow to list available changes if you do not know which one to apply, and it will prompt for a change selection when needed.
