By autonomous-ai/openharness (GitHub) · coding · 1,487 stars · scanned at commit 92aa766

Use this skill when migrating a Phaser 3 project to Phaser 4, or when a user asks about breaking changes, API differences, or how to update their v3 code. Covers renderer changes (pipelines to render nodes), FX/masks to filters, tint system, camera matrix, texture coordinates, DynamicTexture, shaders, lighting, removed game objects, and a full migration checklist. Triggers on: migrate, upgrade, v3 to v4, breaking changes, Phaser 3 to 4, migration guide, update from v3.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'v3-to-v4-migration' ] || [ -L ~/.agents/skills/'v3-to-v4-migration' ]; then echo 'A skill folder named v3-to-v4-migration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/autonomous-ai/openharness' "$d" && git -C "$d" checkout --quiet '92aa7660f44e222456248fc9ad16ed0e0f19d43f' -- 'store/agents/phaser/skills/v3-to-v4-migration' && mkdir -p ~/.agents/skills && cp -R "$d"/'store/agents/phaser/skills/v3-to-v4-migration' ~/.agents/skills/'v3-to-v4-migration' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'v3-to-v4-migration' ~/.claude/skills/'v3-to-v4-migration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
