Is the Unreal Blueprint Codegen skill free?

Yes. The skill itself is free from maystudios/claude-skills. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Unreal Blueprint Codegen SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Unreal Blueprint Codegen?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Unreal Blueprint Codegen with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 9.6/10

Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 3937d95

No UE5 environment available to compile, so this was scored on evidence: a naive baseline C++ generator reproduces 5 distinct real UE Blueprint-compiler bugs (pinless nodes, pruned exec chain, (0,0) node collision, wrong Modified-vs-StructurallyModified call, missing two-pass compile) that the skill's own 'Critical rules' section explicitly names and fixes, so the skill isn't just restating public docs — it's encoding hard-won debugging knowledge.

What Unreal Blueprint Codegen does

A reference/cookbook skill for writing C++ editor-module code that authors Blueprint and Widget Blueprint assets (event graphs, K2 nodes, UMG hierarchies and animations) instead of hand-clicking them in the UE5 editor. Triggers on tasks like building a Blueprint generator, Fab/Marketplace sample content pipelines, or any call touching FKismetEditorUtilities::CreateBlueprint, UWidgetBlueprintFactory, or UMovieScene tracks; documents the non-obvious two-pass-compile requirement and several UE5.7-specific gotchas.

How to install Unreal Blueprint Codegen

git clone https://github.com/maystudios/claude-skills
mkdir -p ~/.claude/skills
cp -r claude-skills/unreal-blueprint-codegen ~/.claude/skills/unreal-blueprint-codegen

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
