Frontend

Processes research branches from Claude Code Web sessions - merges content, moves docs to docs/research/, and creates GitHub issues. Use when /popkit:next detects research branches or when manually processing research from mobile sessions. Do NOT use for regular feature branches - only for branches matching claude/research-* or containing research documentation.

Expert Next.js - App Router, Server Components, Server Actions, data fetching, rendering strategies, optimization et déploiement

React/Next.js best practices for modern, performant applications.

Design LLM applications using the LangChain framework with agents, memory, and tool integration patterns. Use when building LangChain applications, implementing AI agents, or creating complex LLM workflows.

Work on Rust crates in packages/rust_viterbo. Use for crate layout, commands (fmt/clippy/test/bench), and coding conventions.

Forensic, high-fidelity context handover for seamless continuation in a new chat. Produces a single Markdown transfer artifact plus reusable templates, preserving decisions, requirements, non-negotiables, and open loops without truncation by judgment. Not for code continuation unless explicitly stated.

Use Open Props CSS custom properties for consistent design tokens. Use when setting up design systems, choosing spacing/color values, or wanting battle-tested CSS variables without heavy dependencies.

Build production agentic applications on OCI using Oracle Agent Development Kit with multi-agent orchestration, function tools, and enterprise patterns

Memory preservation for Claude Code sessions. Use when approaching token limits, needing to /reset or /compact, switching between complex tasks, or preserving critical session state before context loss. Creates comprehensive memory dumps at /tmp/total-recall containing current state, decisions, artifacts, and next steps for seamless context restoration.

TanStack Start specialist for file-based routing, SSR, and server functions with React

Evaluates Catz Android coding challenge submissions against SWORD Health requirements. Use when reviewing or assessing this coding challenge. Produces a structured markdown report with seniority level assessment (Junior/Mid/Senior/Staff) and confidence rating, covering requirements compliance, architecture, code quality, testing, and documentation.

Apply YAGNI (You Aren't Gonna Need It) principle when evaluating feature requests, reviewing speculative code, or preventing over-engineering. Use when assessing whether to build functionality now vs later.

Implements CSS-in-JS styling with styled-components using tagged template literals, theming, and dynamic props. Use when wanting component-scoped CSS-in-JS, dynamic styling based on props, or theming support.

Use when researching AI agents, LLMs, hosting solutions, OCR technologies, video generation models, or evaluating technology stacks. Apply when user asks to research, compare, evaluate, or investigate technologies, frameworks, models, or tools. Use proactively when technical decisions require research backing.

Use when implementing Weavr UI components for secure payment flows, authentication (password/passcode), KYC/KYB verification, or card display

Use PROACTIVELY when developing Claude Code hooks to implement content-based deduplication and prevent duplicate insight storage across sessions

Adds BetterAuth authentication to Apso backends. Handles entity setup, code generation, auto-fixes, and verification. Triggers when user needs to add authentication, setup auth, or integrate BetterAuth.

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Guide through REFACTOR phase - improve code while maintaining green

This skill activates when you're debugging TypeScript/JavaScript build errors, compilation failures, or type mismatches. Provides patterns for common errors, root cause analysis techniques, and fixes for type-related issues across frameworks.
