release-notes

name: release-notes description: Generate and maintain .NET release notes from features.json. Uses generate-changes for authoritative shipped-change data, generate-features for scoring/triage, update-existing-branch for incremental reruns on populated branches, editorial-scoring for the shared rubric, api-diff/dotnet-inspect for API verification, and a multi-model review-release-notes pass for final editorial QA. compatibility: Requires GitHub MCP server or gh CLI for cross-repo queries. Pairs with the generate-changes, generate-features, update-existing-branch, editorial-scoring, api-diff, and review-release-notes skills. Claude Opus 4.6 is the default workflow model; the preferred final reviewer pair is Claude Opus 4.6 + GPT-5.4 for broader editorial feedback.

.NET Release Notes

Generate and maintain release notes for .NET preview, RC, and GA releases.

This skill is the editorial writing stage of the pipeline. It turns a scored features.json file into the markdown that ships in this repository.

How it works

1. generate-changes diffs source-manifest.json between VMR refs to produce changes.json
2. generate-features reads changes.json, resolves revert/backout relationships, and emits features.json with optional scores using the shared editorial-scoring rubric
3. update-existing-branch handles incremental reruns when a milestone branch already exists, merging deltas instead of restarting from scratch
4. api-diff / dotnet-inspect verifies public APIs and confirms suspect features still exist in the shipped build
5. release-notes writes curated markdown using the higher-value entries from features.json
6. review-release-notes runs a final multi-model editorial QA pass against the scoring rubric and examples
7. Output is a set of pull requests per release milestone in dotnet/core: a base PR that holds shared metadata (changes.json, features.json, README.md, build-metadata.json) and one PR per component file. Each component PR targets the base branch so component teams review and edit their file in isolation. See pr-layout.md for the full layout and naming scheme.

Local testing (no PRs)

To dry-run the skill against a milestone, only create the branch set locally. Don't push the branches or create the PRs.

Existing-branch reruns

When the milestone branch set already exists and contains drafted markdown, invoke update-existing-branch. That shared skill is the canonical playbook for refreshing changes.json, merging the delta into features.json, integrating new material into existing sections, and handling review comments without clobbering human edits.
