changelog

When this skill is invoked:

1. Read the argument for the target version or sprint number. If a version is given, use the corresponding git tag. If a sprint number is given, use the sprint date range.

1b. Check git availability — Verify the repository is initialized:

• Run git rev-parse --is-inside-work-tree to confirm git is available
• If not a git repo, inform the user and abort gracefully

2. Read the git log since the last tag or release:

   Copy

   git log --oneline [last-tag]..HEAD
   

   If no tags exist, read the full log or a reasonable recent range (last 100 commits).

3. Read sprint reports from production/sprints/ for the relevant period to understand planned work and context behind changes.

4. Read completed design documents from design/gdd/ for any new features that were implemented during this period.

5. Categorize every change into one of these categories:

   • New Features: Entirely new gameplay systems, modes, or content
   • Improvements: Enhancements to existing features, UX improvements, performance gains
   • Bug Fixes: Corrections to broken behavior
   • Balance Changes: Tuning of gameplay values, difficulty, economy
   • Known Issues: Issues the team is aware of but have not yet resolved

6. Generate the INTERNAL changelog (full technical detail):

# Internal Changelog: [Version]
Date: [Date]
Sprint(s): [Sprint numbers covered]
Commits: [Count] ([first-hash]..[last-hash])

## New Features
- [Feature Name] -- [Technical description, affected systems]
  - Commits: [hash1], [hash2]
  - Owner: [who implemented it]
  - Design doc: [link if applicable]

## Improvements
- [Improvement] -- [What changed technically and why]
  - Commits: [hashes]
  - Owner: [who]

## Bug Fixes
- [BUG-ID] [Description of bug and root cause]
  - Fix: [What was changed]
  - Commits: [hashes]
  - Owner: [who]

## Balance Changes
- [What was tuned] -- [Old value -> New value] -- [Design intent]
  - Owner: [who]

## Technical Debt / Refactoring
- [What was cleaned up and why]
  - Commits: [hashes]

## Known Issues
- [Issue description] -- [Severity] -- [ETA for fix if known]

## Metrics
- Total commits: [N]
- Files changed: [N]
- Lines added: [N]
- Lines removed: [N]

7. Generate the PLAYER-FACING changelog (friendly, non-technical):

# What is New in [Version]

## New Features
- **[Feature Name]**: [Player-friendly description of what they can now do
  and why it is exciting. Focus on the experience, not the implementation.]

## Improvements
- **[What improved]**: [How this makes the game better for the player.
  Be specific but avoid jargon.]

## Bug Fixes
- Fixed an issue where [describe what the player experienced, not what was
  wrong in the code]
- Fixed [player-visible symptom]

## Balance Changes
- [What changed in player-understandable terms and the design intent.
  Example: "Healing potions now restore 50 HP (up from 30) -- we felt
  players needed more recovery options in late-game encounters."]

## Known Issues
- We are aware of [issue description in player terms] and are working on a
  fix. [Workaround if one exists.]

8. Output both changelogs to the user. The internal changelog is the primary working document. The player-facing changelog is ready for community posting after review.

Guidelines

• Never expose internal code references, file paths, or developer names in the player-facing changelog
• Group related changes together rather than listing individual commits
• If a commit message is unclear, check the associated files and sprint data for context
• Balance changes should always include the design reasoning, not just the numbers
• Known issues should be honest -- players appreciate transparency
• If the git history is messy (merge commits, reverts, fixup commits), clean up the narrative rather than listing every commit literally
