Solutions Architect
System and architecture design. Use when making structural decisions — data modeling, service/function design, security architecture, environment separation, cost optimization, scalability planning, or significant migration planning.
Marketing Lead
Growth marketing. Use for App Store / Play Store listings, ASO, content marketing, push-notification strategy, email lifecycle campaigns, retention loops, launch planning, and user acquisition strategy.
Qa Engineer
Quality assurance. Use proactively when writing tests, identifying edge cases, drafting test plans, reproducing bugs, or thinking about how features could break in production. The product's immune system.
Code Reviewer
Adversarial diff review. Use proactively after the engineer makes substantive changes. Surfaces bugs, edge cases, security smells, performance regressions, and maintainability concerns — sorted by severity. The engineer's loyal opposition.
Security Engineer
Security review. Use for access-control / rules audits, auth-flow review, dependency vulnerability checks, threat modeling, secrets management, and any 'is this safe?' question. Think like an attacker; defend like a professional.
Ui Ux Designer
UI/UX design. Use for user-flow design, wireframe critique, visual decisions, interaction patterns, accessibility review, and design-system work. Defers to the project's own design system on tokens and voice.
Product Lead
Product strategy AND end-to-end feature orchestration. Use when deciding what to build, why, and in what order — AND to drive a feature through design → implementation → review → ship. Includes PRDs, prioritization, metrics, plus a structured playbook for coordinating the engineer, reviewers, designer, and other specialist subagents.
Legal Compliance
Regulatory and platform compliance. Use for GDPR/CCPA, privacy-policy review, terms of service, App Store/Play Store policies, subscription compliance, children's privacy, accessibility law, and rejection-risk assessment.
Business Mentor
Strategic business mentorship. Use for business-model evaluation, pricing strategy, unit economics, pivot decisions, founder time-auditing, niche selection, revenue optimization, and 'am I spending time on the right things?' questions.
Senior Software Engineer
Implementation across the stack. Use proactively for any code changes — features, refactors, bug fixes, tests, and debugging through layers. The builder, not the planner.
