FAQPage Schema
How do I update Spec Kit templates in a local repository without losing my custom conventions?▼

To update Spec Kit templates safely, this Skill applies upstream release diffs while preserving your local conventions like Japanese localization, SPEC-[UUID8] identifiers, and non-branch-based workflows. It automates template and script synchronization to maintain consistency across your repository.

What does synchronizing upstream Spec Kit releases actually protect in my local environment?▼

Synchronizing upstream Spec Kit releases protects your existing localization rules and SPEC-[UUID8] identifiers by performing safe diffs and merges. It targets templates, commands, and scripts, ensuring your local governance rules are maintained without overwriting your customized operational standards.

Can I sync Spec Kit updates if my repository uses a non-branch-based workflow?▼

Yes, you can sync Spec Kit updates with a non-branch-based workflow. This Skill is specifically designed for local repositories that avoid branch operations, applying upstream changes through safe diffs and merges while keeping your localized templates and scripts fully intact.

Do I need specific identifiers to apply Spec Kit updates to my local repository?▼

Yes, you need SPEC-[UUID8] identifiers set up in your local environment to apply Spec Kit updates safely. This Skill requires access to upstream sources and relies on these identifiers to reconcile changes accurately while preserving your existing localized conventions.

What is the best way to automate template and script synchronization for Spec Kit?▼

The best way to automate template and script synchronization is using a workflow that fetches the latest upstream release and applies safe diffs. This Skill automates the reconciliation of templates, commands, and scripts, ensuring upstream alignment while preserving local governance and SPEC-[UUID8] identifiers.

Why does my Spec Kit update workflow fail to preserve localization during merges?▼

Spec Kit updates fail to preserve localization when standard merges overwrite custom conventions. This Skill prevents this by targeting repositories with specific localization rules and SPEC-[UUID8] identifiers, using safe diffs to reconcile upstream changes without losing your localized templates and scripts.
