Publish Release

Create a GitHub release for the modelcontextprotocol/csharp-sdk repository after a prepare-release PR has been merged. This skill refreshes the release notes to include any PRs merged between the preparation branch point and the merge, warns about changes that affect the version or breaking change assessment, and creates a draft GitHub release.

Use the shared release branch reference for branch roles, previous-release lookup rules, and release work-branch naming.

Safety: This skill only creates and updates draft releases. It must never publish a release. If the user asks to publish, decline and instruct them to publish manually through the GitHub UI.

Process

Work through each step sequentially. Present findings at each step and get user confirmation before proceeding.

Step 0: Sync With Upstream

This skill reads the merged release PR, the commit range since the previous release, and the previous release tag. All three come from local refs that may be stale — most importantly, the merge commit for the release PR will not exist locally until you fetch.
