Defines product requirements, user stories, acceptance criteria, and MVP scope. Activates when planning features, writing user stories, defining requirements, creating product specs, scoping MVPs, or answering 'what should we build'. Does not handle technical architecture, API design, database schema, or implementation decisions (architect).
Plans and executes comprehensive testing strategy across frontend, backend, and AI tiers. Activates when writing tests, testing features, setting up test infrastructure, checking coverage, running E2E tests, or performance testing. Does not handle writing production code (backend-developer or frontend-developer), vulnerability/security review (security), or infrastructure deployment (devops).
Integrates one contributor branch at a time into the integration branch: semantic merge of curated KG files and tracker tables, unconditional regeneration of generated projections, full validation, and an append-only integration evidence run ending in a prepared merge commit. Activates when merging contributor PRs, running the merge train, or reconciling knowledge-graph/tracker state at merge time. Does not resolve semantic conflicts (architect or product-manager own those), review code (code-reviewer), test features (quality-engineer), or push to any branch (maintainer).
Builds the AI intelligence layer including LLM integrations, agentic workflows, MCP servers, and intelligent automation in Python. Activates when adding AI features, building agents, implementing MCP servers, integrating LLMs, creating prompts, or adding intelligence to the app. Does not handle core business logic or APIs (backend-developer), frontend UI (frontend-developer), infrastructure (devops), or security review (security).
Designs system architecture, data models, API contracts, and technical specifications. Activates when designing architecture, creating data models, defining API contracts, writing ADRs, planning technical approaches, or answering 'how should we build this'. Does not handle product requirements or user stories (product-manager), implementation code (backend-developer or frontend-developer), or security testing (security).
Implements backend services, APIs, data access, and domain logic using C# .NET and Clean Architecture. Activates when building APIs, implementing endpoints, creating entities, writing backend code, adding migrations, or implementing business logic. Does not handle frontend UI (frontend-developer), AI/LLM features (ai-engineer), infrastructure or Docker (devops), or architecture design (architect).
Writes technical blog posts, devlogs, tutorials, and retrospectives based on completed project work. Also produces channel-specific amplification content (LinkedIn, Reddit, dev.to, etc.) derived from a completed primary post. Activates when writing blog posts, creating devlogs, writing about features, summarizing builds, writing retrospectives, documenting learnings, or producing social amplification content. Does not handle official API or operations documentation (technical-writer), writing production code (backend-developer or frontend-developer), or security reviews (security).
Reviews code quality, architecture compliance, test adequacy, and acceptance criteria mapping. Activates when reviewing code, checking PRs, reviewing changes, assessing code cleanliness, or verifying acceptance criteria coverage. Does not handle security vulnerability scanning (security), writing production code (backend-developer or frontend-developer), or writing tests (quality-engineer).
