Release Note Generation Skill

Generate professional release notes for PowerToys milestones by collecting merged PRs, summarizing each PR with the local CLI agent, grouping by label, and producing user-facing summaries.

Output Directory

All generated artifacts are placed under Generated Files/ReleaseNotes/ at the repository root (gitignored).

When to Use This Skill

Generate release notes for a milestone
Summarize PRs merged in a release
Generate per-PR review summaries locally for release-notes copy
Assign milestones to PRs missing them
Collect PRs between two commits/tags
Update README.md for a new version
Prepare GitHub release assets (download installers/symbols + compute hashes)

Prerequisites

GitHub CLI (gh) installed and authenticated — The collection script uses gh pr view and gh api graphql to fetch PR metadata and co-author information. Run gh auth status to verify; if not logged in, run gh auth login first. See Step 1.0.0 for details.
MCP Server: github-mcp-server installed (used to fetch PR diffs/files for the local-agent review step)
For prepare-release-assets.ps1 only: Azure CLI authenticated against the Microsoft tenant (az login) with the azure-devops extension; access to the microsoft/Dart ADO project

Required Variables

⚠️ Before starting, confirm {{ReleaseVersion}} with the user. If not provided, ASK: "What release version are we generating notes for? (e.g., 0.98)"

Variable	Description	Example
`{{ReleaseVersion}}`	Target release version	`0.98`

Workflow Overview

┌────────────────────────────────┐
│ 1.0 Verify gh auth + MemberList │

Step	Action	Details
1.0	Verify prerequisites	`gh auth status` must pass; generate MemberList.md
1.1	Collect PRs	From previous release tag on `stable` branch → `sorted_prs.csv`
1.2	Assign Milestones	Ensure all PRs have correct milestone
2.1–2.4	Label PRs	Auto-suggest + human label low-confidence
3.1–3.3	Reviews & Grouping	Local agent summarizes each PR diff into `CopilotSummary` → (optional refresh) → group by label
4.1–4.2	Summaries & Final	Generate grouped summaries, then consolidate

Detailed workflow docs

Do not read all steps at once—only read the step you are executing.

Available Scripts

Script	Purpose
dump-prs-since-commit.ps1	Fetch PRs between commits/tags
group-prs-by-label.ps1	Group PRs into CSVs
collect-or-apply-milestones.ps1	Assign milestones
diff_prs.ps1	Incremental PR diff
prepare-release-assets.ps1	Download installers + symbols from an ADO build, compute SHA256, emit the "Installer Hashes" markdown table for the GitHub release page

Conventions

Terminal usage: Disabled by default; only run scripts when user explicitly requests
Batch generation: Generate ALL grouped_md files in one pass, then human reviews
PR order: Preserve order from sorted_prs.csv in all outputs
Label filtering: Keeps Product-*, Area-*, GitHub*, *Plugin, Issue-*

Troubleshooting

Issue	Solution
`gh` command not found	Install GitHub CLI and add to PATH
No PRs returned	Verify milestone title matches exactly
Empty `CopilotSummary` for many PRs	Run Step 3.1 (local-agent summaries). Do not use `mcp_github_request_copilot_review` from a CLI/coding agent — the GitHub API rejects bot-initiated review requests, so the column will stay empty.
Many unlabeled PRs	Return to labeling step before grouping
`prepare-release-assets.ps1` fails with "Failed to acquire ADO access token"	Run `az login` and ensure you have access to the `microsoft/Dart` ADO project
