Expert guide for Unreal Engine 5.x C++ development, covering UObject hygiene, performance patterns, and best practices.

  • Works in 3 steps: Robust Component Lookup → Interface Implementation → Async Loading (Soft References)
  • Game Development work in your project
  • SKILL.md covers When to Use, Core Principles, Naming Conventions (Strict) and Common Patterns, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Unreal Engine Cpp Pro is an agent skill from aiskillstore/marketplace. Expert guide for Unreal Engine 5.x C++ development, covering UObject hygiene, performance patterns, and best practices.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `skill-report.json`).

It sits in Game Development. It works with Unreal Engine and C++. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “/unreal-engine-cpp-pro”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Robust Component Lookup
  2. Interface Implementation
  3. Async Loading (Soft References)

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are cpp).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unreal Engine Cpp Pro loads about 1.1k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 434 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 434 words (~1,127 tokens).

“This skill provides expert-level guidelines for developing with Unreal Engine 5 using C++. It focuses on writing robust, performant, and standard-compliant code.”
