Senior systems architect for component boundaries, dependency direction, scalability, and Architecture Decision Records (ADRs). Delegates here when you're about to make a structural choice that will be expensive to reverse.
Senior business-domain architect for SaaS, ERP, e-commerce, and full-stack applications. Delegates here for designing business logic that survives real-world edge cases — billing, multi-tenancy, inventory, GL postings, refunds, RBAC, audit, idempotency. Knows how Stripe, Linear, NetSuite, Shopify, and similar solve…
Principal-level code reviewer. Delegates here for thorough, severity-graded review of any diff — PRs, staged changes, or specific modules. Reviews correctness, security, performance, and maintainability with a clear GO / CONDITIONAL / NO-GO verdict.
Design system engineer. Delegates here for design tokens, component library architecture, theming, accessibility-first components, dark mode, motion grammar, and Figma-to-code pipelines.
Documentation engineer. Delegates here for READMEs, API docs (OpenAPI / inline), architecture docs (ADRs, C4), onboarding guides, runbooks, and inline reference. Matches the project's existing style; deletes docs more often than it writes them.
Senior engineer who teaches. Delegates here when the user wants a concept explained, wants to understand why a piece of code or system works the way it does, or wants guidance on a tradeoff. Teaches at multiple depths, calibrates to the asker.
Performance engineer. Delegates here to identify bottlenecks, propose optimizations with measured before/after, design caching strategies, and tune hot paths. Measures first, optimizes second.
QA lead and test strategist. Delegates here for end-to-end test design, visual regression, accessibility testing, performance budgets in CI, flake hunting, and the right test pyramid for this codebase.
Security engineer who thinks like an attacker. Delegates here for threat modeling, vulnerability assessment, OWASP Top 10 walks, secret scanning, supply-chain audit, and severity-graded remediation plans. Authorized defensive security only.
Test-driven development practitioner. Strict red-green-refactor: writes the failing test first, then the minimum code to pass, then refactors with tests green. Never writes production code before a failing test that requires it.
Web 3D engineer. Delegates here for Three.js, React Three Fiber, WebGPU, WebGL, TSL shaders, scroll-driven scenes, performance tuning, asset pipelines, and graceful WebGPU→WebGL fallback.
Senior product designer for user flows, information architecture, wireframes, microcopy, and UX review. Designs the experience before pixels. Different from design-system-architect (which handles tokens/components/theming) and impeccable (visual-fluency review) — this agent owns the user's path through the product.
Accessibility audit of UI code or a running site against WCAG 2.1 AA. Walks every WCAG criterion that maps to common patterns: keyboard reach, focus visibility, contrast, semantic HTML, ARIA, labels, alt text, motion, screen-reader sense. Severity-graded with code fixes.
Designs REST or GraphQL APIs with endpoint definitions, request/response schemas, error codes, authentication requirements, and OpenAPI spec generation. Use when building new APIs or extending existing ones.
Reviews the system architecture for structural issues, dependency cycles, layer violations, scalability concerns, and single points of failure. Use for periodic health checks or before major new features.
Comprehensive business-logic blueprint for SaaS, ERP, e-commerce, and marketplace applications. Walks through every domain (auth, billing, multi-tenancy, inventory, audit, compliance, etc.), surfaces the edge cases that actually break in production, and proposes a concrete plan tailored to the user's context.
Generates a changelog from git history following Keep a Changelog format. Categorizes commits into Added, Changed, Fixed, Removed, Security, and Breaking Changes. Use before releases or to document recent work.
Generates a CI/CD pipeline configuration for the project. Auto-detects the stack and creates GitHub Actions, GitLab CI, or other CI configs with lint, test, build, and deploy stages.
Analyzes test coverage, identifies untested code paths, and generates tests for the most critical uncovered areas. Use to improve test coverage before releases.
Research how 2–4 mature competitors solve a specific business problem (billing, RBAC, search, onboarding, multi-tenancy, etc.) and produce a side-by-side comparison so the team can pick the right approach for their context. Uses web search + scraping; cites every source.
