The "Check for existing changeset" step is checking whether any.changeset/*.md file exists in the repo, which will be true on branches created from main (this repo already contains many changesets). As a result, exists will almost always be true and the workflow will never create a changeset for Dependabot PRs.

Instead, detect whether the PR introduces a changeset relative to the base branch (e.g. reuse the same logic as CI: pnpm exec changeset status --since origin/${{ github.base_ref }}), or at least check for the presence of the specific file you intend to create (.changeset/dependabot-pr-<number>.md).

Copilot uses AI. Check for mistakes.
