Generate Player-Facing Patch Notes

---

name: patch-notes description: "Generate player-facing patch notes from git history, sprint data, and internal changelogs. Translates developer language into clear, engaging player communication." argument-hint: "[version] [--style brief|detailed|full]" user-invocable: true allowed-tools: Read, Glob, Grep, Write, Bash model: haiku agent: community-manager

Phase 1: Parse Arguments

• version: the release version to generate notes for (e.g., 1.2.0)
• --style: output style — brief (bullet points), detailed (with context), full (with developer commentary). Default: detailed.

If no version is provided, ask the user before proceeding.

---

Phase 2: Gather Change Data

• Read the internal changelog at production/releases/[version]/changelog.md if it exists
• Also check docs/CHANGELOG.md for the relevant version entry
• Run git log between the previous release tag and current tag/HEAD as a fallback
• Read sprint retrospectives in production/sprints/ for context
• Read any balance change documents in design/balance/
• Read bug fix records from QA if available

If no changelog data is available (neither production/releases/[version]/changelog.md nor a docs/CHANGELOG.md entry for this version exists, and git log is empty or unavailable):

"No changelog data found for [version]. Run /changelog [version] first to generate the internal changelog, then re-run /patch-notes [version]."

Verdict: BLOCKED — stop here without generating notes.

Phase 2b: Detect Tone Guide and Template

Tone guide detection — before drafting notes, check for writing style guidance:

1. Check .claude/docs/technical-preferences.md for any "tone", "voice", or "style" fields or sections.
2. Check docs/PATCH-NOTES-STYLE.md if it exists.
3. Check design/community/tone-guide.md if it exists.
4. If any source contains tone/voice/style instructions, extract them and apply them to the language and framing of the generated notes.
5. If no tone guidance is found anywhere, default to: player-friendly, non-technical language; enthusiastic but not hyperbolic; focus on what the player experiences, not what the developer changed.

Template detection — check whether a patch notes template exists:

1. Glob for docs/patch-notes-template.md and .claude/docs/templates/patch-notes-template.md.
2. If found at either location, read it and use it as the output structure for Phase 4 instead of the built-in style templates (Brief / Detailed / Full). Fill in the template's sections with the categorized data.
3. If not found, use the built-in style templates as defined in Phase 4.

Phase 3: Categorize and Translate

Categorize all changes into player-facing categories:

• New Content: new features, maps, characters, items, modes
• Gameplay Changes: balance adjustments, mechanic changes, progression changes
• Quality of Life: UI improvements, convenience features, accessibility
• Bug Fixes: grouped by system (combat, UI, networking, etc.)
• Performance: optimization improvements players might notice
• Known Issues: transparency about unresolved problems

Translate developer language to player language:

• "Refactored damage calculation pipeline" → "Improved hit detection accuracy"
• "Fixed null reference in inventory manager" → "Fixed a crash when opening inventory"
• "Reduced GC allocations in combat loop" → "Improved combat performance"
• Remove purely internal changes that don't affect players
• Preserve specific numbers for balance changes (damage: 50 → 45)

- [Feature 2]

**Changes**
- [Balance/mechanic change with before → after values]

**Fixes**

- [Bug fix 2]

**Known Issues**
- [Issue 1]

Detailed Style

# Patch [Version] — [Title]

## Highlights
[1-2 sentence summary of the most exciting changes]

## New Content
### [Feature Name]
[2-3 sentences describing the feature and why players should be excited]

## Gameplay Changes
### Balance
| Change | Before | After | Reason |
| ---- | ---- | ---- | ---- |
| [Item/ability] | [old value] | [new value] | [brief rationale] |

### Mechanics

## Quality of Life
- [Improvement with context]

## Bug Fixes

Full Style

Includes everything from Detailed, plus:

Phase 5: Review Output

Check the generated notes for:

• No internal jargon (replace technical terms with player-friendly language)
• No references to internal systems, tickets, or sprint numbers
• Balance changes include before/after values
• Bug fixes describe the player experience, not the technical cause
• Tone matches the game's voice (adjust formality based on game style)

---

Phase 6: Save Patch Notes

Present the completed patch notes to the user along with: a count of changes by category, and any internal changes that were excluded (for review).

Ask: "May I write these patch notes to docs/patch-notes/[version].md?"

If yes, write the file to docs/patch-notes/[version].md, creating the directory if needed. Also write to production/releases/[version]/patch-notes.md as the internal archive copy.

---

Phase 7: Next Steps

Verdict: COMPLETE — patch notes generated and saved.

• Run /release-checklist to verify all other release gates are met before publishing.
• Share the patch notes draft with the community-manager for tone review before posting publicly.
