What it does
Ue Code Authoring is an agent skill from JasonMa0012/MooaToon. Use when writing or modifying UE C++ (classes, actors, components, subsystems, interfaces, function libraries) with Rider MCP available. Value over bash/grep: IDE diagnostics catch UHT/reflection errors and missing module deps without a full build; lintfiles enforces cross-file consistency. DO NOT TRIGGER for: Blueprint-only tasks, editor automation with no C++. When Rider MCP is unavailable, runs in reduced mode — standard file tools only, IDE diagnostics skipped.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `reference/rider-mcp-tools.md`, `reference/rider-tools.md` and `reference/ue-cpp-conventions.md`).
It sits in Development, covering Linting and formatting and MCP servers. It works with Model Context Protocol, C++, Bash and Unreal Engine. The repository describes itself as: The Ultimate Solution for Cinematic Toon Rendering in UE5.
When your agent uses it
- Modifying UE C++ (classes
- Function libraries) with Rider MCP available
- : Blueprint-only tasks
- Editor automation with no C++
Example prompts
- “/ue-code-authoring”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash, Write, Edit, ToolSearch
Workflow steps
11 steps, taken from the step headings in SKILL.md.
- UE Project Check
- Task Is Coding-Related Check
- Rider MCP Availability Check
- Clarify (if ambiguous)
- Pre-flight
- Write Code
- Rider Diagnostics (per file)
- Batch Lint (skip for isolated single-file fixes)
- Build
- Post-Build Quality Gate
- Reformat
What it can do on your machine
Read from SKILL.md and the folder at commit 23a255b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepBashWriteEditToolSearch
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 bash).
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
Ue Code Authoring loads about 1.9k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 900 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Glob, Grep, Bash, Write, Edit, ToolSearch
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 900 words (~1,899 tokens).
“Unreal Engine C++ authoring workflow backed by Rider MCP for IDE-grade code quality. Three additions over a plain editor approach: (1) Rider diagnostics catch issues before a full build, (2) lint_files enforces project-wide consistency, (3) get_project_problems surfaces cross-file issues invisible…”
