## What it does

This skill finds the latest Git tag, establishes the change boundary, and asks GitHub CLI for merged PRs with `gh pr list`. It assigns each PR to Added, Fixed, Security, Changed, Deprecated, or Removed using its title prefix and labels. Items without a matching rule go to Changed.

It then checks non-merge commits after the tag and looks for related PRs. Commits with no PR are placed under `Ungrouped commits`. The skill rewrites the `[Unreleased]` block in `CHANGELOG.md`, keeps the `<!-- next-header -->` marker, and adds a link for every PR.

Before replacing entries that an operator edited, it asks for approval. It also displays the generated section for review. The skill runs only after an explicit request, and `gh pr list` needs access to the repository’s live GitHub data.

## When to use it
- collect PRs merged after the latest tag
- sort changes into Keep a Changelog sections
- find commits that have no linked PR
- rewrite `[Unreleased]` with PR links
- prepare a changelog section for review

## Example prompts
- Build the next changelog from every PR merged after the latest tag.
- Check commits after the previous release and put ones without a PR under `Ungrouped commits`.
- Update `[Unreleased]` in `CHANGELOG.md`, then show me the section before release work continues.

# jackin-release-notes

**Classify** every PR merged since the last release tag into a Keep a Changelog bucket, then write the `[Unreleased]` section of `CHANGELOG.md`. The bar is exhaustive — every merged PR accounted for, none dropped, none doubled.

## When to use

- Before a release, to populate the changelog.
- When the operator asks to preview what the next release would contain.

## When NOT to use

- Cutting the release itself → `jackin-release` (it runs this skill as its notes step).

## Process

1. **Find the boundary.** `LAST_TAG=$(git describe --tags --abbrev=0)`; if none, start from the initial commit (`git rev-list --max-parents=0 HEAD`). `TAG_DATE=$(git log -1 --format=%aI "$LAST_TAG")`.

   *Done when* you hold the boundary commit and its date.

2. **Gather merged PRs.** `gh pr list --state merged --base main --search "merged:>$TAG_DATE" --json number,title,labels,mergedAt`.

   *Done when* every PR merged after the tag is in the list.

3. **Classify each.** Sort by Conventional Commits prefix and label:

   | Prefix / label | Bucket |
   |---|---|
   | `feat:` / `feature` | **Added** |
   | `fix:` / `bug` | **Fixed** |
   | `security:` | **Security** |
   | `refactor:`, `chore:`, `docs:`, `ci:`, `build:` | **Changed** |
   | `deprecate:` | **Deprecated** |
   | `remove:` | **Removed** |
   | no match | **Changed** (default) |

   Strip the prefix from the title; capitalize the first word (`feat: add TUI launcher` → `Add TUI launcher`).

   *Done when* every PR sits in exactly one bucket.

4. **Catch ungrouped commits.** `git log <last-tag>..HEAD --oneline --no-merges`; for each, `gh pr list --state merged --search "<sha>"`. Commits with no PR land under **Ungrouped commits**.

   *Done when* every non-merge commit since the tag is matched to a PR or listed.

5. **Write `[Unreleased]`.** Keep a Changelog format: one section per non-empty bucket, each entry linking its PR (`[#N](…/pull/N)`). Replace the existing `[Unreleased]` block (between `## [Unreleased]` and the next `## [`) — ask before overwriting entries an operator already edited. Keep the `<!-- next-header -->` marker intact.

   *Done when* `CHANGELOG.md` carries every merged PR under the right bucket, empty buckets omitted, and the marker survives.

6. **Present for review.** Show the section; let the operator re-classify or reword. Do not proceed to a release until approved.
