User Guide

• When to use: Generate release notes from git history, sprint data, and internal changelogs. Game: player-facing patch notes. Product: developer-facing release notes with API/CLI/UI categories.
• Inputs: Command arguments: /patch-notes [version] [--style brief|detailed|full] [--audience players|developers|all]; project artifacts referenced below; user decisions and approvals before writes.
• Outputs: Primary artifacts, reports, or conversation guidance described below; write files only after user approval.
• Memory-bank writes: None.
• Next steps: Follow the workflow hand-off or next-step guidance below; recommendations do not auto-run and require explicit user command/approval.

Phase 0: Domain Detection

Detect the project domain by checking for concept documents in design/cdd/:

• Game: design/cdd/game-concept.md exists → use [Game] paths below
• Product: design/cdd/product-concept.md exists → use [Product] paths below
• Neither: default to game paths (preserves backward compatibility)

---

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.
• --audience: [Game] players (default). [Product] developers (for API/CLI users), users (for end-user features), all (both). Default: developers for product, players for game.

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
• [Game] Read any balance change documents in design/balance/
• [Game] Read bug fix records from QA if available
• [Product] Read migration files and API spec diffs 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 standards/technical-preferences.md for any "tone", "voice", or "style" fields or sections.
2. Check docs/PATCH-NOTES-STYLE.md if it exists.
3. [Game] 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 domain-appropriate tone:
   • [Game] Player-friendly, non-technical language; enthusiastic but not hyperbolic; focus on what the player experiences, not what the developer changed.
   • [Product] Developer-friendly, precise language; include breaking changes prominently; include migration steps; focus on what changed and why.

Template detection — check whether a release notes template exists:

1. Glob for docs/patch-notes-template.md and templates/patch-notes-template.md.
2. If found at either location, read it and use it as the output structure for Phase 4.
3. If not found, use the built-in style templates as defined in Phase 4.

Phase 3: Categorize and Translate

[Game] Player-Facing Categories

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)

[Product] Developer-Facing Categories

Categorize all changes into developer/user-facing categories:

• Breaking Changes: API changes that require consumer updates, removed endpoints, changed behaviour
• New Features: new endpoints, new CLI commands, new SDK methods, new capabilities
• Improvements: performance gains, error message improvements, documentation updates
• Bug Fixes: grouped by component (API, CLI, SDK, UI)
• Deprecations: features/endpoints that will be removed in a future version (with timeline)
• Security: security fixes (include CVE references if applicable)
• Dependency Updates: notable dependency changes (major versions, security patches)
• Migration Guide: step-by-step instructions for upgrading (if breaking changes exist)
• Known Issues: transparency about unresolved problems

Translate developer-internal language to release note language:

• Internal refactoring that doesn't affect the API surface → omit
• "Changed the auth middleware" → "Authentication now requires X-API-Key header (see migration guide)"
• Include specific error code changes, response shape changes, CLI flag renames
• Always state upgrade impact: "No action required" / "Action required: [what to do]"

Phase 5: Review Output

[Game] 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)

[Product] Check the generated notes for:

• Breaking changes are prominently flagged with migration steps
• Deprecations include timeline and replacement
• Bug fixes describe the observable symptom, not the root cause
• Links to docs/migration guides are functional
• No exposed internal paths, credentials, or infrastructure details
• Upgrade impact is clearly stated for each change

---

Phase 6: Save Release Notes

Present the completed release 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 release 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 — release notes generated and saved.

• Run /release-checklist to verify all other release gates are met before publishing.
• [Game] Share the patch notes draft with the community-manager for tone review before posting publicly.
• [Product] Share the release notes draft with the product owner and developer relations for review before publishing.
