DevOps patterns: containerization, CI/CD, deployment strategies, monitoring. Use when containerizing apps, setting up pipelines, or deploying services.

Extracts reusable patterns from sessions. Use at session end to capture debugging insights and project-specific knowledge.

Strategic compaction skill: suggests context compression at logical breakpoints. Use to suggest compaction at logical intervals during development sessions.

Git version control best practices: branching, commits, merging, conflict resolution, PR workflows. Use when managing branches, creating commits, merging code, or resolving conflicts.

Backend development patterns for services, error handling, logging, caching. Use when building backend services, APIs, or microservices.

Cross-validate code, architecture or design decisions using a second model. Use for critical decisions, complex refactoring, security reviews.

Code quality assurance strategies. Parent skill for quality-related skills: security (security review) and debug (systematic debugging).

Security review skill: comprehensive security checklist and patterns. Use when adding authentication, handling user input, working with secrets, or creating API endpoints.

Systematic debugging methods, log analysis, and performance diagnostics. Use when debugging issues, analyzing errors, or troubleshooting incidents.

Database design, query optimization, migrations, and indexing. Use when designing schemas, writing queries, or managing migrations.

Code exploration strategies for understanding unfamiliar codebases. Use when exploring unknown code, debugging, or analyzing architecture.

RESTful API design patterns and best practices. Use when creating endpoints, designing APIs, or implementing routes.

Native app development strategies including iOS/macOS (Apple platforms), Tauri desktop apps. Use when developing native mobile or desktop applications.

Session lifecycle management. Parent skill for session-related skills: learning (pattern extraction) and compact (context compression).

Frontend patterns: component design, state management, performance, accessibility. Use when building web frontends, components, or client-side apps.

Guide for building, configuring, and deploying microfrontends on Vercel. Use this skill when the user mentions microfrontends, multi-zones, splitting an app across teams, independent deployments, cross-app routing, incremental migration, composing multiple frontends under one domain, microfrontends.json, @vercel/microfrontends, the microfrontends local proxy, or path-based routing between Vercel projects. Also use when the user asks about shared layouts across projects, navigation between microfrontends, fallback environments, asset prefixes, or feature flag controlled routing.

End-to-end Solana development playbook (Jan 2026). Prefer Solana Foundation framework-kit (@solana/client + @solana/react-hooks) for React/Next.js UI. Prefer @solana/kit for all new client/RPC/transaction code. When legacy dependencies require web3.js, isolate it behind @solana/web3-compat (or @solana/web3.js as a true legacy fallback). Covers wallet-standard-first connection (incl. ConnectorKit), Anchor/Pinocchio programs, Codama-based client generation, LiteSVM/Mollusk/Surfpool testing, and security checklists.

Coordinates planning, delegation, and evaluation across architect and code agent workspaces. Use when asked to "write instructions for code agent", "initialize architect workspace", "grade code agent work", "send instructions", or "verify code agent setup".

Create MATLAB plain text Live Scripts (.m files) following specific formatting rules. Use when generating MATLAB scripts, educational MATLAB content, Live Scripts, or when the user requests .m files with rich text formatting.

Assesses team fitness and composes agent teams. Use when "set up a team", "team for this", "should I use agents", "design a team", "how many agents", "agent team".
