At a glance

Ranks the changes in a release manifest and writes a scored features file that release notes, docs and blog posts can each cut at their own threshold.

  • Works in 6 steps: Start from changes.json → Resolve revert state before scoring → Score what shipped → …
  • Ranking shipped changes before drafting release notes
  • SKILL.md covers Purpose, Schema contract, Default scoring guidance and Process, plus 1 more section
  • Calls jq and gh; reaches github.com

What it does

Triage is the job here: the skill reads `changes.json`, which lists what shipped, and writes `features.json`, which lists what is worth telling people about. The new file keeps the same top-level fields, change IDs, repo and product keys and commit objects, so the two files can be joined, diffed and compared without conversion.

Change entries gain optional fields: a numeric `score`, a short `score_reason`, a per-dimension `score_breakdown`, a `breaking_changes` flag kept apart from the score, and `reverted_by` and `reverts` links. A 0-10 scale is suggested, where the top score marks a lead story and lower bands become grouped release-note material. Scoring follows the shared `editorial-scoring` rubric, and regenerating diffs or writing final markdown belong to other skills.

When your agent uses it

  • Ranking shipped changes before drafting release notes
  • Flagging breaking changes that need a short upgrade note
  • Producing one scored file that docs and blog posts filter by different cutoffs

Example prompts

  • “Generate features.json from changes.json for the upcoming .NET release.”
  • “Score every change in changes.json and mark the ones that break upgrades.”
  • “Rank this release's changes so the blog post only gets the top scoring items.”

Requirements

  • A `changes.json` manifest of shipped changes

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Start from changes.json
  2. Resolve revert state before scoring
  3. Score what shipped
  4. Use API evidence to refine the score
  5. Merge incrementally when features.json already exists
  6. Write features.json

What it can do on your machine

Read from SKILL.md and the folder at commit 44927bc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Release Feature Scoring loads about 2.2k tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 1,058 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Generate `features.json` from `changes.json` by ranking and annotating shipped changes. `features.json` keeps the same schema as `changes.json` and adds optional scoring fields so release notes, docs, and blog posts can apply different cutoffs. Uses the shared `editorial-scoring` rubric. DO NOT USE FOR: regenerating VMR diffs (use generate-changes) or writing final markdown (use release-notes).

Generate features.json

Create a scored, reusable feature list from changes.json.

This is the triage stage of the release notes pipeline. It turns the comprehensive manifest of shipped changes into a ranked set of candidates for external communication.

Use editorial-scoring as the canonical rubric. Do not invent a different notion of importance for this step.

Purpose

changes.json answers what shipped.

features.json answers what is worth talking about, while staying schema-compatible with changes.json so the two files can be joined, diffed, and compared easily.

Schema contract

features.json intentionally mirrors changes.json:

  • same top-level fields: release_version, release_date, changes, commits
  • same id, repo, product, and commit key structure
  • same commits{} object so cross-file joins still work

The only additions are optional enrichment fields on change entries, such as:

  • score (number) — higher means more likely to be documented
  • score_reason (string) — short explanation of the score
  • score_breakdown (object) — optional per-dimension scoring details
  • breaking_changes (bool) — mark changes that users may need to react to, even when they are not headline items
  • reverted_by (array<string>) — optional PR URLs or refs that later backed out this change
  • reverts (array<string>) — optional change IDs or PR URLs that this entry reverts or partially reverts

This schema is intentionally loose and can grow as the workflow learns what it needs.

breaking_changes is separate from score. A change might only be a 3 or 4 on reader interest, but still need to be carried forward as a short migration note because it can affect people upgrading.

Default scoring guidance

Use a consistent numeric scale within a file. The recommended starting point is 0-10:

ScoreReader reactionTypical outcome
10"This is the first feature I'll enable or test."Lead story
8+"I'm going to use this when I upgrade."Strong release-note feature
6+"I'm glad I know about this."Good grouped release-note material
4+"Someone will care; I can look it up later."Optional mention or grouping candidate
2+"This is a mystery to me."Usually skip
0Internal gobbledygookNever document

See editorial-scoring for the shared rubric and feature-scoring.md for the detailed heuristics.

Apply the 80/20 rule from that document: prefer features that make sense to most upgraders, and only keep niche items when the broader audience can still appreciate why they matter.

Process

1. Start from changes.json

Do not invent features from memory, roadmaps, or PR titles found elsewhere. Everything in features.json must trace back to changes.json.

2. Resolve revert state before scoring

Do a quick mechanical revert pass before assigning any positive scores. This step exists because the original PR may appear in the current changes.json while the revert lands in a later preview and therefore does not appear in the same file.

Start with the obvious cases:

bash
jq -r '.changes[] | select(.title | test("(?i)^(partial(ly)?\\s+)?revert\\b|\\bback out\\b")) | [.repo, .title, .url] | @tsv' changes.json

Then, for each candidate you might promote into the draft, search the source repo for later merged PRs that explicitly revert or back out that PR number or URL:

bash
gh search prs --repo dotnet/<repo> --state merged \
  "\"This reverts https://github.com/dotnet/<repo>/pull/<number>\" OR \"revert <number>\" OR \"back out <number>\"" \
  --json number,title,mergedAt,url

When a revert is found:

  • annotate the original entry with reverted_by
  • annotate the revert entry with reverts, when both are present in the file
  • set the original score to 0 unless you can verify the shipped build still contains the feature

Do not promote an item to section-worthy status until this pass is complete.

3. Score what shipped

Look for signals such as:

  • new public APIs or meaningful behavioral changes
  • developer productivity wins
  • performance work with clear user impact
  • compatibility or migration significance
  • changes that need docs or samples to be usable
  • features whose value is obvious to a broad slice of users

If a change is important mainly because users need to adjust to it, set breaking_changes: true even if the score stays low. Do not inflate the score just to keep the item visible.

If several individually modest changes cluster around one theme, keep that cluster in mind as you score. Do not inflate each entry, but do preserve the related items so downstream writing can roll them up into one coherent feature writeup. Title prefixes and labels are often useful clues here, such as a set of [browser] runtime changes or multiple "Unsafe evolution" items.

Down-rank or exclude:

  • infra and dependency churn
  • test-only changes
  • internal refactors with no user-facing impact
  • items that violate the product-boundary rule in editorial-rules.md
  • reverts and partial work that did not survive into the build
  • items that mostly require insider knowledge to understand why they matter

4. Use API evidence to refine the score

If a change depends on public APIs, use api-diff / dotnet-inspect to confirm the API exists in the actual build. Missing or reverted APIs should be scored down or excluded.

5. Merge incrementally when features.json already exists

If the milestone branch already has a features.json, do not throw that work away just because changes.json was regenerated. For the full rerun workflow, follow update-existing-branch.

Use the existing file as the editorial baseline:

  • preserve prior scores and annotations for unchanged entries
  • score only the newly added or materially changed IDs
  • revisit older scores only when new evidence or review feedback justifies it
  • keep useful human edits instead of flattening them back to a machine pass

This should feel like a merge operation, not a full restart.

6. Write features.json

The output typically lives next to changes.json:

text
release-notes/{major.minor}/preview/{previewN}/features.json
release-notes/{major.minor}/{major.minor.patch}/features.json

Complete this stage before drafting component markdown. Write the actual changes[] and commits{} from changes.json, with the same change IDs and optional editorial annotations. A placeholder with only a release version or a note that feature selection will happen on component branches is not a features.json output. Score and explain the noteworthy candidates before handing them to the writing stage; individual low-value entries do not need scores. When review identifies a noteworthy candidate that should be left out, record the editorial reason in that entry's score_reason and adjust its score if needed. Even when nothing is worth a feature writeup, keep the real shipped changes in the file so the final review can check the editorial cut.

Keep the file mechanically friendly:

  • preserve every shipped change ID and commit key from changes.json
  • make score optional, not required
  • keep score_reason brief and evidence-based

How downstream skills use it

  • release-notes uses higher-scored entries to draft markdown
  • release-notes can also surface low-scored entries with breaking_changes: true as one-line callouts in a breaking-changes section
  • review-release-notes re-checks the scores against editorial examples and trims over-scored items
  • Docs/blog workflows can apply their own cutoffs later
  • Humans can adjust scoring without changing the source-of-truth shipped data
