What it does

Orchardcore Theme Creator is an agent skill from OrchardCMS/OrchardCore. Creates new OrchardCore themes with proper structure, manifest, layouts, and assets. Use when the user needs to create a new theme, customize layouts, or set up frontend assets.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/assets.md` and `references/theme-structure.md`).

It sits in Frontend & Design. The repository describes itself as: Orchard Core is an open-source modular and multi-tenant application framework built with ASP.NET Core, and a content management system (CMS) built on top of that framework. The licence is BSD-3-Clause.

When your agent uses it

  • The user needs to create a new theme
  • Customize layouts
  • Set up frontend assets

Example prompts

  • “Use the orchardcore-theme-creator skill to create new OrchardCore themes with proper structure, manifest, layouts, and assets”
  • “/orchardcore-theme-creator”

Requirements

  • Node.js

Workflow steps

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

  1. Create Theme Directory
  2. Create Required Files
  3. Create Manifest.cs
  4. Create Project File
  5. Create Layout
  6. Add Assets (Optional)
  7. Build and Activate

What it can do on your machine

Read from SKILL.md and the folder at commit 545c6a0. 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

    Shell commands in SKILL.md call:

    • dotnet
    • yarn

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

  • Network

    No URLs in SKILL.md. Its commands use yarn, which can reach the network depending on how they are called.

    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

Orchardcore Theme Creator loads about 941 tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 172 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~941
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.2k

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.

OrchardCore Theme Creator

This skill guides you through creating new OrchardCore themes following project conventions.

Prerequisites

  • OrchardCore repository at D:\orchardcore
  • .NET SDK 10.0+ installed
  • Node.js 22.x and Yarn 4.x (for asset compilation)

Theme Creation Workflow

Step 1: Create Theme Directory
bash
mkdir src/OrchardCore.Themes/YourTheme
cd src/OrchardCore.Themes/YourTheme
Step 2: Create Required Files

Every theme needs these files:

  1. Manifest.cs - Theme metadata
  2. YourTheme.csproj - Project file
  3. Views/Layout.cshtml - Main layout
  4. Views/_ViewImports.cshtml - Razor imports
Step 3: Create Manifest.cs
csharp
using OrchardCore.DisplayManagement.Manifest;
using OrchardCore.Modules.Manifest;

[assembly: Theme(
    Name = "Your Theme",
    Author = ManifestConstants.OrchardCoreTeam,
    Website = ManifestConstants.OrchardCoreWebsite,
    Version = ManifestConstants.OrchardCoreVersion,
    Description = "Your theme description."
)]

Extending a base theme:

csharp
[assembly: Theme(
    Name = "Your Theme",
    BaseTheme = "TheBlogTheme",  // Inherit from base
    // ... other properties
)]
Step 4: Create Project File
xml
<Project Sdk="Microsoft.NET.Sdk.Razor">
  <PropertyGroup>
    <AddRazorSupportForMvc>true</AddRazorSupportForMvc>
    <Title>Your Theme</Title>
    <Description>Your theme description.</Description>
  </PropertyGroup>

  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\..\OrchardCore\OrchardCore.Theme.Targets\OrchardCore.Theme.Targets.csproj" />
  </ItemGroup>
</Project>
Step 5: Create Layout

Create Views/Layout.cshtml:

html
<!DOCTYPE html>
<html lang="@Orchard.CultureName()">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title>@RenderTitleSegments(Site.SiteName, "before")</title>
    <resources type="StyleSheet" />
</head>
<body>
    <zone Name="Header" />
    <main>
        <zone Name="Messages" />
        <zone Name="Content" />
    </main>
    <zone Name="Footer" />
    <resources type="FootScript" />
</body>
</html>
Step 6: Add Assets (Optional)

Create asset structure:

Assets/
├── scss/site.scss
├── js/site.js
└── package.json
Assets.json

See references/assets.md for configuration details.

Step 7: Build and Activate
bash
# Build theme
cd D:\orchardcore
dotnet build src/OrchardCore.Themes/YourTheme

# Build assets (if added)
yarn && yarn build

# Run application
cd src/OrchardCore.Cms.Web
dotnet run -f net10.0

# Activate theme in Admin → Design → Themes
