• The tool ID rename here (github-pull-request_openPullRequest -> github-pull-request_pullRequestInViewport) removes the old contributed tool name. If any prompts/skills/users still reference the old ID, they will break. Consider contributing a deprecated alias for the previous name (alongside the new name) and/or registering both IDs in code during a transition period.

Renaming the contributed language model tool name values is a breaking change for any existing prompts/skills/users that reference the previous tool IDs (github-pull-request_activePullRequest / github-pull-request_openPullRequest). Since the old IDs are removed from package.json, those references will stop resolving. Consider adding deprecated aliases (keep the old name entries alongside the new ones, or register both IDs in code and continue contributing the old IDs for at least one release) to preserve backward compatibility, and optionally document the deprecation timeline.
