draft-release-notes

A development skill that writes or updates the [Unreleased] part of CHANGELOG.md, the file that records what changed between software releases. It bases the draft on commits, generated GitHub release notes, and change statistics since the last version tag.

In plain words
What is it for?
Use it to prepare a readable changelog section from recent Git changes and revise that section repeatedly before a release.
Why use it?
It keeps the release story current while work is still in progress, without changing version numbers or creating release tags.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

draft-release-notes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Draft Release Notes

Goal

Update the [Unreleased] section at the top of CHANGELOG.md with a narrative release story based on the real changes since the last tag. This is a non-destructive working copy — run it as many times as you want during development.

Workflow

  1. Identify the last release tag and gather changes.

    LAST_TAG=$(git tag --list "v*" --sort=-v:refname | head -n 1)
    echo "Last tag: $LAST_TAG"
    

    Then collect raw material from three sources:

    a. Commit log since last tag:

    git log --oneline "$LAST_TAG"..HEAD
    

    b. GitHub-generated release notes preview (PR titles, new contributors):

    gh api repos/:owner/:repo/releases/generate-notes \
      -f tag_name="vNEXT" \
      -f target_commitish="$(git rev-parse HEAD)" \
      -f previous_tag_name="$LAST_TAG" \
      --jq '.body'
    

    c. Diff stat for theme analysis:

    git diff --stat "$LAST_TAG"..HEAD
    
  2. Draft the release narrative.

    Write markdown for the [Unreleased] section following the format below. Do not include the ## [Unreleased] heading itself — just the body content.

  3. Update CHANGELOG.md.

    Replace everything between ## [Unreleased] and the next ## [ heading with the new draft. Preserve the HTML comment header and all existing release sections below.

    The [Unreleased] section must always exist and always be the first section after the header comments.

  4. Do NOT commit, tag, or bump versions. Just leave the file modified in the working tree.

Release Story Format

Structure the [Unreleased] section like this:

## [Unreleased]

<One strong opening paragraph: what this release is about and why it matters.
Tie it to concrete shipped changes. No vague hype.>

<One paragraph on major technical shifts, if applicable.>

### <Feature/Theme Group>
- Bullet points with specifics
- Reference PRs where available: ([#123](https://github.com/jamiepine/voicebox/pull/123))

### <Another Group>

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
