Phase 1: Parse Arguments

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.

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.

---

Phase 2: Gather Change Data

Read the git log since the last tag or release:

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

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

Read sprint reports from

production/sprints/

for the relevant period to understand planned work and context behind changes.

Read completed design documents from

design/gdd/

for any new features implemented during this period.

---

Phase 3: Categorize Changes

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
• Miscellaneous: Changes that do not fit the above categories, or commits whose messages are too vague to classify confidently

For each commit, check whether the message contains a task ID or story reference (e.g.

[STORY-123]

,

TR-

,

#NNN

, or similar). Count commits that lack any task reference and include this count in the Phase 4 Metrics section as:

Commits without task reference: [N]

.

Phase 5: Generate Player-Facing Changelog

# 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.]

Phase 6: Output

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.

---

Phase 7: Offer File Write

After presenting the changelogs, ask the user:

"May I write this changelog to

docs/CHANGELOG.md

? [A] Yes, append this entry (recommended if the file already exists) [B] Yes, overwrite the file entirely [C] No — I'll copy it manually"

• Check whether

  docs/CHANGELOG.md

  exists before asking. If it does, default the recommendation to [A] append.
• If the user selects [A]: append the new internal changelog entry to the top of the existing file (newest entries first).
• If the user selects [B]: overwrite the file with the new changelog.
• If the user selects [C]: stop here without writing.

After a successful write: Verdict: CHANGELOG WRITTEN — changelog saved to

docs/CHANGELOG.md

. If the user declines: Verdict: COMPLETE — changelog generated.

---

Phase 7: Next Steps

• Use

  /patch-notes [version]

  to generate a styled, saved version for public release.
• Use

  /release-checklist

  before publishing the changelog externally.

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
