# 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).

```
Generated Files/ReleaseNotes/
├── milestone_prs.json           # Raw PR data from GitHub
├── sorted_prs.csv               # Sorted PR list with Copilot summaries
├── prs_with_milestone.csv       # Milestone assignment tracking
├── grouped_csv/                 # PRs grouped by label (one CSV per label)
├── grouped_md/                  # Generated markdown summaries per label
└── v{VERSION}-release-notes.md  # Final consolidated release notes
```

## 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](./references/step1-collection.md) 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](./scripts/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` |

| 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 |

## Available Scripts

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

- [Detailed Instructions](./references/Instruction.md) - Legacy full documentation

## 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 |
