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.

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 -

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
templates/
└── nextjs-15/
├── scaffold.yaml
├── architect.yaml
├── 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 {}
