gum-formsFRB Gum Forms codegen and how Forms controls take cursor input.
Gum Forms is an agent skill from vchelaru/FlatRedBall. FRB Gum Forms codegen and how Forms controls take cursor input. Triggers: XxxForms.Generated.cs, FormsClassCodeGenerator, UserControl, Cursor.WindowOver, clicks eaten by Gum UI.
Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Project scaffolding. The repository describes itself as: Cross-platform 2D game engine focused on ultimate productivity built in .NET. The licence is MIT.
Read from SKILL.md and the folder at commit fa654ab. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Gum Forms loads about 367 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 143 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.
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.
The full file from vchelaru/FlatRedBall at commit fa654ab, republished under its MIT licence (© vchelaru). 143 words, ~367 tokens.
.claude/skills/gum-forms/SKILL.md (or your agent's skills folder).FRB's Gum codegen makes two classes for each Gum element: a Visual runtime (GumRuntimes\XxxRuntime.Generated.cs) and a Forms class (Forms\...\XxxForms.Generated.cs). A Gum screen paired with an FRB screen gets both. MonoGameGum and FRB2 merged the two, so don't carry this split over from them. See [[gum-integration]] for the rest of the Gum plugin.
| Piece | Location |
|---|---|
| Forms class per element | FRBDK\Glue\GumPlugin\GumPlugin\CodeGeneration\FormsClassCodeGenerator.cs |
| Forms instance on an FRB screen | FormsObjectCodeGenerator.cs (same folder) |
| Forms controls (Button, UserControl...) | Engines\Forms\FlatRedBall.Forms\FlatRedBall.Forms.Shared\Controls\ |
FormsClassCodeGenerator makes each component's Forms class inherit FlatRedBall.Forms.Controls.UserControl, including plain layout panels. So "is this a Forms control?" says nothing about whether it's interactive.GumCursorLogic.ShouldGumBlockWorldSelection). Gum controls still receive the click either way.

FRB Gum Forms codegen and how Forms controls take cursor input. Gum Forms is an agent skill from vchelaru/FlatRedBall. FRB Gum Forms codegen and how Forms controls take cursor input.
Gum Forms fits situations like: tasks that involve Project scaffolding.
Run `npx skills add vchelaru/FlatRedBall --skill gum-forms -a claude-code`. Or copy the skill folder (.claude/skills/gum-forms in vchelaru/FlatRedBall) into .claude/skills/gum-forms in your project. Claude Code loads it when a task matches its description.
Run `npx skills add vchelaru/FlatRedBall --skill gum-forms -a codex`. Or copy the skill folder (.claude/skills/gum-forms in vchelaru/FlatRedBall) into .agents/skills/gum-forms in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add vchelaru/FlatRedBall --skill gum-forms -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gum-forms, .gemini/skills/gum-forms, .github/skills/gum-forms and .opencode/skills/gum-forms in your project.
SKILL.md names no scripts, command-line tools or credentials: Gum Forms is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Gum Forms is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 367 tokens (SKILL.md is roughly 1.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Gum Forms: Hz New Project Creation (meta-quest/agentic-tools, 215 stars), Godot Project Templates (thedivergentai/GD-Agentic-Skills, 816 stars), Godot Project Setup (jame581/GodotPrompter, 799 stars) and Gm Scaffold (RandallLiuXin/GodotMaker, 550 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
vchelaru (a GitHub user) maintains it in vchelaru/FlatRedBall, which has 578 GitHub stars. The repository holds 32 skills in this directory. The repository was last updated on October 8, 2026.
