When the user wants to reduce churn, improve user engagement, or increase lifetime value. Also use when the user mentions "retention", "churn", "users leaving", "engagement", "DAU/MAU", "user activation", or "why are users uninstalling". For onboarding-specific issues, see app-launch. For monetization, see monetization-strategy.
Build interfaces with design engineering craft — the intersection of design and code. Use this skill when the user asks to build UI components, interactive elements, animations, micro-interactions, or polished web experiences. Triggers on mentions of "design engineer", "interaction design", "micro-interactions", "craft", "polish", "delight", "animation", "motion design", "haptics", "toast", "command palette", "design system components", or requests for interfaces that feel alive, responsive, and meticulously detailed. This skill should also be used when the user wants to add invisible details, fine-tune interactions, or make something "feel right". Complements the frontend-design skill by focusing specifically on interaction quality, motion, and engineering craft.
Expert guidance for Django REST Framework class-based views using Classy DRF (https://www.cdrf.co). Use when selecting or debugging APIView, GenericAPIView, concrete generic views, mixin combinations, or ViewSet/GenericViewSet/ModelViewSet behavior; tracing method resolution order (MRO); understanding which method to override (`create` vs `perform_create`, `update` vs `perform_update`, `destroy` vs `perform_destroy`, `get_queryset`, `get_serializer_class`); and comparing behavior across DRF versions. Do not use for function-based views, GraphQL, FastAPI/Flask, frontend work, or non-DRF backend frameworks.
When the user wants to design or optimize the funnel that takes web visitors into installing and onboarding the app — including smart app banners, web-to-app deep links, deferred deep links, web onboarding (Stripe-paid web flow before app install), QR codes, "open in app" CTAs, and the trade-off between paying on web vs in-app. Use when the user mentions "web to app", "smart app banner", "Stripe before app", "web paywall before install", "Branch web SDK", "web funnel for app", "AppsFlyer OneLink web", "Universal Links", "App Links", "QR code to app", "open in app", "deferred deep link from web", or "should I sell on web first then push to app". For pure in-app onboarding, see onboarding-optimization. For deep link infra, see attribution-setup.
Raise frontend visual judgment for web interfaces with a bias toward refined product-grade composition, precise component craftsmanship, disciplined interaction states, controlled motion, and coherent depth systems. Use when generating, reviewing, or refactoring web UI that feels generic, cluttered, flat, over-styled, theatrically animated, visually imprecise, or AI-generated.
Transform approved requirements into comprehensive technical designs. Define system architecture, component interactions, data models, and interfaces to create a blueprint for implementation.
Conduct a full-spectrum public intelligence (OSINT) investigation on any individual given their name, job title, and company. Produces a structured intelligence dossier. Use when asked to research a person, build a profile, investigate a contact, create a dossier, or gather publicly available intelligence on an individual.
Add and update the documentation website for Syncpack. Use when making user-facing changes to the codebase.
Self-improving agent architecture using ChromaDB for continuous learning, self-evaluation, and improvement storage. Agents maintain separate memory collections for learned patterns, performance metrics, and self-assessments without modifying their static .md configuration.
Subscribe to real-time stock market data via WebSocket (A-shares, HK stocks, ETFs). Use this skill when the user wants to monitor live stock prices, set up real-time alerts, or stream minute-level K-line data. Requires a valid real-time subscription token purchased from the management platform.
Design RESTful APIs with clear endpoints, proper HTTP methods, and consistent response formats. Use when planning or building APIs.
Review healthcare and EHR software interfaces against a comprehensive design style guide grounded in NIST, FDA, IEC 62366, ISO 9241, ISO 14971, WCAG 2.1, ONC SAFER, and HL7 FHIR standards. Produces a report-only assessment without modifying code or designs. Use when an agent needs to evaluate clinical UI screens, data display, forms, alerts, or workflows for patient-safety, usability, accessibility, and data-clarity compliance.
