AI Code Toolkit

AI Code Toolkit

This repo provides:

• project and feature scaffolding via templates
• file-level design guidance before edits
• rule-based review after edits
• design-system discovery for frontend work

Why This Exists

As projects scale, conventions in docs like CLAUDE.md, AGENTS.md, and style guides become hard to keep concise and consistently applied by AI agents. This toolkit moves those conventions into reusable template configs (scaffold.yaml, architect.yaml, RULES.yaml) so agents can discover only the relevant guidance when needed.

Quick Start

Requirements:

• Node.js >= 18
• an MCP-compatible agent such as Claude Code, Cursor, or Gemini CLI

1. Initialize a Workspace

# Existing project
npx @agiflowai/aicode-toolkit init

# New project
npx @agiflowai/aicode-toolkit init --name my-app --project-type monolith

This creates templates/ and .toolkit/settings.yaml. Projects reference templates through sourceTemplate in project.json or .toolkit/settings.yaml.

2. Configure MCP

init can configure MCP automatically. For manual setup, add the servers you need to your agent config.

Example for Claude Code:

{
  "mcpServers": {
    "scaffold-mcp": {
      "command": "npx",
      "args": ["-y", "@agiflowai/scaffold-mcp", "mcp-serve", "--admin-enable"]
    },
    "architect-mcp": {
      "command": "npx",
      "args": [
        "-y", "@agiflowai/architect-mcp", "mcp-serve",
        "--admin-enable",
        "--design-pattern-tool", "codex",
        "--review-tool", "gemini-cli"
      ]
    },
    "style-system": {
      "command": "npx",
      "args": ["-y", "@agiflowai/style-system", "mcp-serve"]
    }
  }
}

Useful flags:

• --admin-enable: enable admin/template-authoring tools
• --design-pattern-tool <tool>: use an LLM to filter design patterns
• --review-tool <tool>: use an LLM for review output

3. Verify

Ask the agent:

What boilerplates are available?

It should call list-boilerplates. If not, restart the agent.

scaffold-mcp

Generates projects and feature boilerplate from templates.

Core tools:

• list-boilerplates
• use-boilerplate
• list-scaffolding-methods
• use-scaffold-method

Admin tools:

• generate-boilerplate
• generate-feature-scaffold
• generate-boilerplate-file

architect-mcp

Provides file-specific patterns before edits and reviews changes against RULES.yaml.

Core tools:

• get-file-design-pattern
• review-code-change

Admin tools:

• add-design-pattern
• add-rule

style-system

Provides theme, CSS class, and component discovery tools.

Core tools:

• list_themes
• get_css_classes
• get_component_visual
• list_shared_components
• list_app_components

one-mcp

Provides progressive tool discovery to reduce MCP prompt overhead.

Typical Workflow

Create a Project

User: "Create a Next.js app called dashboard"

Agent:
1. list-boilerplates
2. use-boilerplate
3. Project is generated

Add a Feature

User: "Add a products API route"

Agent:
1. list-scaffolding-methods
2. use-scaffold-method
3. Feature files are generated

Edit a File Safely

User: "Add a products page"

Agent:
1. get-file-design-pattern
2. edit the file using the returned patterns and rules
3. review-code-change
4. fix any violations

Style a Component

User: "Style the button with our theme colors"

Agent:
1. get_css_classes
2. list_shared_components
3. update the component
4. get_component_visual

Template Structure

└── nextjs-15/

    ├── RULES.yaml
    └── boilerplate/

scaffold.yaml

Defines boilerplates and feature scaffolds.

boilerplates:
  - name: nextjs-15-app
    description: "Next.js 15 with App Router"
    targetFolder: apps
    includes:
      - boilerplate/**/*

features:
  - name: add-route
    description: "Add route with page and layout"
    variables_schema:
      name: { type: string, required: true }
    includes:
      - features/route/**/*

architect.yaml

Defines file-level patterns that should be shown before edits.

patterns:
  - name: server-component
    description: "Default for page components"
    file_patterns:
      - "**/app/**/page.tsx"
    description: |
      - Use async/await for data fetching
      - Keep components focused on rendering
      - Move business logic to server actions

RULES.yaml

Defines review rules. Rules can be inherited from a global templates/RULES.yaml.

version: '1.0'
template: typescript-lib
rules:
  - pattern: src/services/**/*.ts
    description: Service Layer Implementation Standards
    must_do:
      - rule: Create class-based services with single responsibility
        codeExample: |-
          export class DataProcessorService {
            async processData(input: string): Promise<ProcessedData> {
              // Implementation
            }
          }
      - rule: Use dependency injection for composability
    must_not_do:
      - rule: Create static-only utility classes - use functions
        codeExample: |-
          // ❌ BAD
          export class Utils {
            static format(s: string) {}
          }

          // ✅ GOOD
          export function format(s: string): string {}

Project Types

│   └── web-app/
│       └── project.json
├── packages/
│   └── shared-lib/
│       └── project.json
└── templates/

Monolith

Monoliths use .toolkit/settings.yaml.

version: "1.0"
projectType: monolith
sourceTemplate: nextjs-15
