Compares HEAD with the latest published version to analyze real changes, group by type, and recommend version bumps. Use before publishing a release to understand what actually changed.

Release Change Analyzer

Analyzes unpublished changes by comparing HEAD with the latest published version. Reads actual diffs instead of just copying commit messages.

When to Use This Skill

Before publishing a new release
Deciding between major/minor/patch version bump
Writing accurate release notes based on real code changes
Reviewing what changed since last deployment

What This Skill Does

Step 1: Identify Published Version

# npm
npm view <package-name> version 2>/dev/null || echo "not published"

# PyPI
pip index versions <package-name> 2>/dev/null | head -1

# Or use git tags
git tag --sort=-v:refname | head -1

Step 2: Analyze Real Changes

# Get actual diff (NOT just commit messages)
git diff v{published-version}..HEAD --stat
git diff v{published-version}..HEAD

For each commit, MUST:

Read the actual diff to understand WHAT CHANGED
Describe the REAL change in plain language
Explain WHY it matters (if not obvious)

Step 3: Group and Report

## Unpublished Changes (v{published} -> HEAD)

### Features
| Scope | What Changed |
|-------|--------------|
| auth | Added OAuth2 support with Google and GitHub providers |

### Fixes
| Scope | What Changed |
|-------|--------------|
| api | Fixed race condition in concurrent request handling |

### Refactoring
| Scope | What Changed |
|-------|--------------|
| core | Extracted retry logic from 3 services into shared module |

### Breaking Changes
- Removed deprecated `v1/login` endpoint

### Files Changed
42 files changed, 1205 insertions(+), 387 deletions(-)

### Suggested Version Bump
- **Recommendation**: minor
- **Reason**: New features added, no breaking changes in public API

Version Bump Decision

Condition	Bump
Breaking changes in public API	major
New features, no breaking changes	minor
Bug fixes, refactoring, docs only	patch

Anti-Patterns

Copying commit messages verbatim — read the actual diff
Describing "what" without "why" — explain impact
Missing breaking changes — always check public API surface
Guessing at scope — verify from the diff

Example

User: "What changed since last release?"

Output: Reads diff between

v1.2.3

and HEAD, identifies 3 features, 2 fixes, 1 refactor, no breaking changes. Recommends

minor

bump to

v1.3.0
