HF Release Notes

Overview

Generate release notes for huggingface_hub from cached PR JSON files. This skill reads PR metadata, categorizes entries, and produces a formatted markdown release notes document.

Output directory: The prompt will specify the output directory as <output_dir>. All paths below use this placeholder.

Workflow

1. Read PR data

Read all PR JSON files from <output_dir>/tmp/pr_*.json. Each file contains:

{
  "number": 1234,
  "title": "...",
  "author": "username",
  "merged_at": "2026-01-15T10:30:00Z",
  "body": "...",
  "labels": ["highlight", "cli"],
  "url": "https://github.com/huggingface/huggingface_hub/pull/1234",
  "doc_diffs": [
    {
      "filename": "docs/source/en/guides/cli.md",
      "status": "modified",
      "patch": "@@ -10,6 +10,10 @@ ..."
    }
  ]
}

The doc_diffs field contains unified diffs for any .md files under docs/ that were changed in the PR. This is empty ([]) for PRs with no documentation changes.

2. Identify highlights

A PR should be highlighted if:

• It has the "highlight" label on GitHub, or
• You judge it significant enough to deserve a detailed section (e.g., a major new feature, a meaningful UX improvement, or a notable breaking change) even without the label.

Use your judgment — not every feature PR needs a highlight, but don't limit highlights to only labeled PRs. Each highlight section follows this structure:

1. Emoji header — e.g., ## 🖥️ New CLI commands
2. Prose summary — 2-5 sentences describing the user-visible change in flowing text. Avoid bullet points here; write natural sentences. Only use bullets if the content truly calls for a list (e.g., enumerating 4+ distinct sub-features).
3. Code examples — if the PR introduces new commands or APIs, include a fenced code block with a concrete usage example (cherry-pick from doc diffs when available).
4. PR attribution lines — one bullet per PR that contributed to this highlight: - PR title by @author in #1234
