VRC Skills Renovator
Overview
A guide for renovating (filling knowledge, refreshing, and improving quality of) VRChat-related skills in this repository.
Three Pillars of Renovation
| Pillar | Description | Examples |
|---|---|---|
| Fill | Adding missing knowledge | Undocumented APIs, patterns, tips |
| Refresh | Updating outdated information | New SDK version support, removing deprecated APIs |
| Quality Improvement | Improving accuracy and coverage of existing knowledge | Adding code examples, improving explanations |
Target Skills
Path notation:skills/refers to theskills/directory at the repository root.rules/refers to files underskills/unity-vrc-udon-sharp/rules/. This skill itself resides at.claude/skills/unity-vrc-skills-renovator/(dev-only, not distributed via npm).
| Skill | Directory | Content |
|---|---|---|
unity-vrc-udon-sharp | skills/unity-vrc-udon-sharp/ | UdonSharp coding, networking, events |
unity-vrc-world-sdk-3 | skills/unity-vrc-world-sdk-3/ | VRC components, layer settings, world optimization |
Renovation Procedure
Phase 1: Current State Analysis
- Check the current SDK version support for each skill
Read: skills/unity-vrc-udon-sharp/SKILL.md
Read: skills/unity-vrc-world-sdk-3/SKILL.md
→ Check the "Supported SDK version" line in each file- Check the file list for each skill
Glob: skills/unity-vrc-udon-sharp/**/*
Glob: skills/unity-vrc-world-sdk-3/**/*Phase 2: Information Gathering
Execute the following search queries in parallel to collect the latest information:
# Required searches (parallel execution recommended)
1. "VRChat SDK {current year} new features updates changelog"
2. "UdonSharp VRChat SDK 3.{next minor version} changes"
3. "VRChat Worlds SDK {current year} UdonSharp"
4. "VRChat World SDK components new features {current year}"
# Supplementary searches (as needed)
5. "VRChat SDK NetworkCallable parameters"
6. "VRChat SDK persistence PlayerData"
7. "VRChat SDK PhysBones Contacts worlds"See references/search-queries.md for details.
Phase 3: Renovation Plan
Classify collected information by the 3 pillars and target skills:
Classification by Pillar
| Pillar | Content | Action |
|---|---|---|
| Fill | Information not yet in the skill | Add new sections, add code examples |
| Refresh | Outdated information | Update version references, remove deprecated APIs |
| Quality Improvement | Inaccurate or insufficient descriptions | Improve explanations, add patterns |
Classification by Skill
| Category | Target Skill | Examples |
|---|---|---|
| C# API, networking, sync variables | unity-vrc-udon-sharp | NetworkCallable, new events |
| Components, layers, optimization | unity-vrc-world-sdk-3 | New components, setting changes |
| Affects both | Both | SDK version references, Persistence |
Phase 4: Update unity-vrc-udon-sharp
| Priority | File | Update Content |
|---|---|---|
| 1 | SKILL.md | SDK version support, new feature summary |
| 2 | references/constraints.md | Newly available features |
| 3 | references/networking.md | New networking features |
| 4 | references/events.md | New events |
| 5 | references/api.md | New APIs |
| 6 | CHEATSHEET.md | Quick reference update |
| 7 | references/patterns.md | New feature usage patterns |
| 8 | references/troubleshooting.md | Troubleshooting |
Phase 5: Update unity-vrc-world-sdk-3
| Priority | File | Update Content |
|---|---|---|
| 1 | SKILL.md | SDK version support, new feature summary |
| 2 | references/components.md | New components, property changes |
| 3 | references/layers.md | Layer/collision changes |
| 4 | references/performance.md | New optimization guidelines |
| 5 | references/lighting.md | Lighting-related changes |
| 6 | references/audio-video.md | Audio/video-related changes |
| 7 | references/upload.md | Upload procedure changes |
| 8 | CHEATSHEET.md | Quick reference update |
| 9 | references/troubleshooting.md | Troubleshooting |
Phase 6: New File Creation (if needed)
When major new features are added:
- Create a dedicated reference file in the corresponding skill's
references/ - Add a link in the corresponding SKILL.md Resources section
Phase 7: Rules & Enforcement Layer Sync
When the Knowledge layer (references/*.md) changes, always sync the Rules layer and Enforcement layer as well.
7a. Rules Layer — Auto-loaded Rules (skills/unity-vrc-udon-sharp/rules/)
Read: skills/unity-vrc-udon-sharp/rules/udonsharp-constraints.md
Read: skills/unity-vrc-udon-sharp/rules/udonsharp-networking.md
Read: skills/unity-vrc-udon-sharp/rules/udonsharp-sync-selection.md
→ Check for differences with the Knowledge layer and reflect the same facts| Change Type | Target Rule File | Action |
|---|---|---|
| Blocked feature added/removed | udonsharp-constraints.md | Update block list / available list |
| Networking changes | udonsharp-networking.md | Update sync modes, limits, patterns |
| Data budget changes | udonsharp-sync-selection.md | Update budget values, decision tree |
7b. Enforcement Layer — Validation Hooks (hooks/)
Read: skills/unity-vrc-udon-sharp/hooks/validate-udonsharp.sh
Read: skills/unity-vrc-udon-sharp/hooks/validate-udonsharp.ps1
→ Add/remove/modify rules based on constraint changes| Change Type | Hook-side Action |
|---|---|
| Feature unblocked | Remove the corresponding grep pattern |
| New constraint added | Add a new grep pattern |
| Limit value changed | Update threshold (synced_count, etc.) |
| New anti-pattern | Add a new warning rule |
Important: .sh and .ps1 must maintain the same rule set (don't update only one).
7c. Enforcement Layer — Templates (assets/templates/)
Read: skills/unity-vrc-udon-sharp/assets/templates/BasicInteraction.cs
Read: skills/unity-vrc-udon-sharp/assets/templates/SyncedObject.cs
Read: skills/unity-vrc-udon-sharp/assets/templates/PlayerSettings.cs
Read: skills/unity-vrc-udon-sharp/assets/templates/CustomInspector.cs
→ Remove deprecated patterns and reflect new best practices| Change Type | Template-side Action |
|---|---|
| New API becomes recommended | Update template to use the new API |
| Pattern becomes deprecated | Rewrite to the recommended pattern |
| New best practice | Reflect in the relevant template, or create a new template |
Phase 8: Validation
- Unify SDK version references across all files
- Verify cross-reference links between both skills
- Check code sample syntax
- 3-layer consistency check: Verify that Knowledge / Rules / Enforcement reflect the same facts
- Constraint lists are consistent across all 3 layers - Limit values (synced variable count, string length, etc.) are consistent across all 3 layers - Templates do not use blocked features
