patch-notes— agent skill

When this skill is invoked:

1. Parse the 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.

1. Gather change data from multiple sources:

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

1. 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

1. 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)

1. Generate the patch notes using the appropriate style:

Full Style

Includes everything from Detailed, plus:

## Developer Commentary
### [Topic]
> [Developer insight into a major change — why it was made, what was considered,
> what the team learned. Written in first-person team voice.]

1. Review the output 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)

1. Save the patch notes to production/releases/[version]/patch-notes.md,

creating the directory if needed.

1. Output to the user: the complete patch notes, the file path, a count of

changes by category, and any internal changes that were excluded (for review).
