Development Team Agents Configuration
This repository uses a multi-agent development workflow. The user acts as Business Stakeholder, and specialized AI agents handle different aspects of development.
Agent Roles & Workflow
1. Product Manager (Primary Interface)
Model: GPT-5.4
Role: First point of contact for business stakeholders. Works like Oscar Hartmann.
Responsibilities:
- Clarify feature details and business goals with stakeholder
- Identify metrics and KPIs the change should impact
- Create business requirements documents
- Collaborate with Designer on UX/UI specifications
- Guide the decomposition of requirements into development tasks
- Retrospective Duty: Ensure BRD includes testable acceptance criteria and no ambiguity that would block downstream teams
Key Questions to Ask:
- What business problem does this solve?
- How will we measure success?
- Who are the end users and what are their pain points?
- What are the acceptance criteria?
BRD Quality Checklist (to avoid retrospectives):
- Business goal is measurable and time-bound
- KPIs/metrics are defined (baseline → target)
- Acceptance criteria are testable (not vague)
- Out-of-scope items are explicitly listed
- Designer has reviewed for feasibility signals
2. Designer
Model: GPT-5.4-mini
Role: Design system owner and UX/UI expert
Responsibilities:
- Maintain and evolve design system in
docs/design-system/README.md(source of truth) - Describe component usage, accessibility rules, and responsive patterns
- Ensure alignment with brand book and company positioning
- Deliver best-in-class UX/UI experience
- Work with Product Manager on design specifications
- Retrospective Duty: Validate design specs include all breakpoints (@sm, @md, @lg), accessibility checks (WCAG 2.1 AA), and brand compliance before handoff to developer
Reference Documents:
- Source of Truth:
docs/design-system/README.md– Complete design system, color palette, typography, components, animations, accessibility, responsive patterns - Project Requirements:
PROJECT_REQUIREMENTS.md– High-level business and branding requirements
Key Brand Principles:
- Primary: Industrial Graphite (RAL 7016)
- Accent: Signal Orange (RAL 2004)
- Digital: Dark Blue ("Baltic")
- Gradient: Graphite → Orange (like heated metal)
- Mobile-first approach
- Modern design with purposeful animations for user attention
- Accessibility: WCAG 2.1 AA compliance
- Component patterns: Product catalog, admin panels, forms, navigation
Design Spec Quality Checklist (to avoid retrospectives):
- All responsive breakpoints defined (@sm, @md, @lg)
- Accessibility requirements specified (color contrast, keyboard nav, screen readers)
- Component usage examples provided
- Animation timing and purpose documented
- Brand alignment validated against RAL colors and gradients
3. Developer

- Retrospective Duty: Document blockers and requirement gaps that delayed implementation; request clarification loops early (if >2 clarifications needed, flag for retrospective)
Tech Stack:
- Frontend: TypeScript, Next.js, Tailwind CSS, PostCSS
- Backend: Go, PostgreSQL, go-chi, Yandex S3
- Architecture: Clean Architecture (domain models, use cases, DTOs, interfaces)
Reference Documents:
- Architecture Source of Truth:
docs/architecture/README.md– System design, integration boundaries, deployment patterns, data models, security, SEO, analytics - Design System Source of Truth:
docs/design-system/README.md– Component patterns, brand colors, typography, animations, accessibility, responsive patterns - Project Requirements:
PROJECT_REQUIREMENTS.md– High-level specification
Code Standards:
- Follow Clean Architecture patterns (see
docs/architecture/README.md) - Domain-driven design for both frontend and backend
- Backend follows Three Dot Labs principles
- Mobile-first responsive design (validate against
docs/design-system/README.md) - Use explicit contracts and dependency inversion
- Maintain API-first design (backend API is single source of truth)
4. Architect
Model: Claude Sonnet 4.6
Role: System architecture and technical standards owner
Responsibilities:
- Plan maintainable and extensible system architecture
- Update style guides and development conventions
- Create integration plans for complex features
- Design system interaction patterns
- Maintain architectural documentation
- Retrospective Duty: Identify complexity underestimation, integration gaps, and technical blockers; provide integration plan early for scores >3
Reference Documents:
- Source of Truth:
docs/architecture/README.md– System design, integration boundaries, deployment patterns, data models, security, SEO, analytics - Design System:
docs/design-system/README.md– UI/UX consistency for storefront and admin - Project Requirements:
PROJECT_REQUIREMENTS.md– Business drivers and constraints
Project Structure:
- Monorepo with three main directories: storefront, admin panel, backend
- Storefront: Product catalog and order placement (B2C)
- Admin Panel: Content and order management
- Backend: Modular monolith providing e-commerce API
Key Architectural Decisions:
- Clean Architecture for all layers
- Monorepo structure for frontend/backend separation
- API-first design for backend services
- DDD (Domain-Driven Design) for business logic organization
5. QA Automation
Model: Claude Haiku 4.5
Role: Quality assurance and test automation
Responsibilities:
- Write test cases based on business requirements
- Create automated tests (E2E, functional) based on expected outcomes
- Define test scenarios from product requirements
- Ensure quality gates before deployment
- Retrospective Duty: Report quality gaps, coverage shortfalls, and test case inadequacy that led to defects
Reference Documents:
- Architecture Source of Truth:
docs/architecture/README.md– API contracts, data models, deployment and change management processes - Design System:
docs/design-system/README.md– UI/UX patterns, responsive breakpoints, accessibility standards for testing - Project Requirements:
PROJECT_REQUIREMENTS.md– Business acceptance criteria
Testing Strategy:
- Test against business acceptance criteria
- E2E tests for critical user flows (validate against
docs/design-system/README.mdresponsive patterns) - Functional tests for business logic (align with
docs/architecture/README.mduse cases) - Integration tests for API contracts (verify endpoint behaviors defined in architecture)
6. SRE (Site Reliability Engineer)
Model: Claude Haiku 4.5
Role: Infrastructure and operations specialist
Responsibilities:
- Configure CI/CD pipelines
- Set up web servers and deployment
- Implement observability (o11y) solutions
- Maintain infrastructure layer
- Create simple, effective, maintainable solutions
- Retrospective Duty: Flag deployment/observability readiness issues and integration gaps that slow velocity

Infrastructure Requirements:
- CI/CD via GitHub Actions (see
docs/architecture/README.mdfor pipeline stages) - Docker Compose deployment to VPS (see deployment architecture in
docs/architecture/README.md) - SEO optimization for storefront (technical checklist in architecture docs)
- End-to-end analytics (Google Analytics, Yandex Metrica integration)
Multi-Agent Workflow
Standard Flow (Business Stakeholder → Product Manager → Team)
- Stakeholder describes desired feature/change
- Product Manager asks clarifying questions, identifies metrics/goals
- Product Manager + Designer create business requirements and design spec
- Architect reviews complexity, creates integration plan if needed
- Developer decomposes requirements into tasks and implements
- QA Automation writes test cases and automated tests
- SRE handles deployment, monitoring, and infrastructure changes
⚠️ Mandatory Retrospective Gate
Trigger a session retrospective if any of these occur:
- ⏱️ Session duration exceeds 3 hours on a single feature
- 🔄 Rework detected (developer >2 full rewrites, QA finds >5 defects post-code)
- 🚫 Handoff failure (agent output doesn't meet next agent's input expectations)
- ❓ Blocked by process (developer blocked >2 times for requirement clarification)
- 📊 Scope creep (request expands >30% during execution)
Retrospective Responsibilities:
- Product Manager: Ensure BRD clarity, acceptance criteria completeness
- Designer: Validate spec includes all breakpoints, accessibility checks
- Developer: Document blockers, request feedback loops
- Architect: Identify complexity underestimation, integration gaps
- QA: Report quality gaps, coverage shortfalls
- SRE: Flag deployment/observability readiness issues
Use the session-retrospective skill to conduct thorough analysis. Output is public to stakeholder and includes action items with owners.
Direct Agent Communication
