Standards

What are Standards?

Standards are project decisions that inform AI code generation. They ensure consistency across all generated code and documentation.

Standards are established during project initialization and guide every agent interaction. They’re the “rules of the road” for your project.

Standard Types

Tech Stack

Languages, frameworks, databases, infrastructure

Coding Standards

Formatting, linting, naming, testing strategy

Architecture

Architecture style, API design, state management

UX Guide

Design system, styling, accessibility

Establishing Standards

During project initialization:

/specsmd-master-agent
> project-init

The Master Agent guides you through each standard category with facilitation guides.

Tech Stack Standard

Defines your technology choices:

# Tech Stack

## Languages
- **Primary**: TypeScript 5.x
- **Secondary**: Python 3.11+ (for ML pipelines)

## Frontend
- **Framework**: React 18 with Next.js 14
- **Styling**: Tailwind CSS
- **State**: Zustand

## Backend
- **Runtime**: Node.js 20 LTS
- **Framework**: Express.js
- **ORM**: Prisma

## Database
- **Primary**: PostgreSQL 15
- **Cache**: Redis 7
- **Search**: Elasticsearch 8

## Infrastructure
- **Cloud**: AWS
- **Containers**: Docker
- **Orchestration**: ECS Fargate
- **CI/CD**: GitHub Actions

Coding Standards

Defines how code should be written:

# Coding Standards

## Formatting
- Use Prettier with default config
- 2-space indentation
- Single quotes for strings
- Trailing commas in multiline

## Naming Conventions
- **Files**: kebab-case (user-service.ts)
- **Classes**: PascalCase (UserService)
- **Functions**: camelCase (getUserById)
- **Constants**: SCREAMING_SNAKE_CASE (MAX_RETRIES)

## Testing Strategy
- **Unit Tests**: Vitest for business logic
- **Integration Tests**: Supertest for APIs
- **E2E Tests**: Playwright for critical paths
- **Coverage Target**: 80% minimum

## Error Handling
- Use custom error classes extending BaseError
- Always include error codes
- Log errors with structured logging
- Never expose internal errors to clients

Architecture Standard

Defines system design decisions:

# Architecture

## Style
- **Pattern**: Clean Architecture
- **API**: REST with OpenAPI 3.0
- **Communication**: Synchronous HTTP, async via SQS

## Layers
1. **Presentation**: Controllers, DTOs
2. **Application**: Use cases, services
3. **Domain**: Entities, value objects, events
4. **Infrastructure**: Repositories, external services

## API Design
- Resource-based URLs
- HTTP methods for actions
- JSON request/response bodies
- Pagination with cursor-based approach

## State Management
- Server state: React Query
- Client state: Zustand
- Form state: React Hook Form

UX Guide (Optional)

Defines design system and styling:

# UX Guide

## Design System
- Based on custom design tokens
- Component library: shadcn/ui

## Colors
- Primary: #2563eb
- Secondary: #64748b
- Success: #10b981
- Error: #ef4444

## Typography
- Headings: Inter, sans-serif
- Body: Inter, sans-serif
- Mono: JetBrains Mono

## Spacing
- Base unit: 4px
- Scale: 4, 8, 12, 16, 24, 32, 48, 64

## Accessibility
- WCAG 2.1 AA compliance
- Keyboard navigation required
- Screen reader support
- Color contrast 4.5:1 minimum

How Standards Are Used

Agents reference standards when generating code:

Context Loading

Agent reads all standards from Memory Bank

Decision Making

Standards inform architecture and design choices

Code Generation

Generated code follows coding standards

Validation

Output is checked against standards

Updating Standards

Standards can evolve. To update:

Edit the relevant file in memory-bank/standards/
Commit the change with clear rationale
Consider an ADR for significant changes
Inform the team

Changing standards affects all future code generation. Major changes should be documented in an ADR and reviewed by the team.

Best Practices

Be Specific

Vague standards lead to inconsistent code. “Use good naming” is useless. “Use camelCase for functions” is clear.

Document Rationale

Explain why, not just what. Future team members will thank you.

Keep Current

Update standards when the team adopts new practices. Outdated standards are ignored.

Start Simple

You don’t need every detail on day one. Add specifics as patterns emerge.

Standards Catalog

Standards are defined in .specsmd/aidlc/templates/standards/catalog.yaml. This catalog controls:

Which standards exist and their importance
Decisions within each standard
Dependencies between standards
Project type presets

standards:
  tech-stack:
    description: Core technology choices
    facilitation: templates/standards/tech-stack.guide.md

    recommended_standards: [system-architecture, ux-guide]

Extensibility

The catalog is designed for extensibility:

Add New Standards

Add entries to standards: with facilitation guides

Custom Decisions

Add decisions to existing standards

Project Types

Define custom project type presets

Dependencies

Control order via depends_on_standards

Each standard has a facilitation guide (.guide.md) that defines the questions asked during project-init. Customize these to match your team’s decision-making process.
