Debug, develop, and operate apps hosted on Railway (railway.com) from the CLI — list projects/services, tail and filter build/deploy/HTTP logs, read metrics, inspect and set variables, deploy from the current directory, redeploy / restart / roll back, run local commands with the service's env, SSH into containers, and open a DB shell. Authenticates via the `RAILWAY_TOKEN` environment variable (account token, or project-scoped token). Optional bundled scripts (`scripts/preflight.sh`, `scripts/debug.sh`, `scripts/smoke.sh`) are Onsager-specific wrappers — other repos can ignore them or fork. Triggers include "deploy to railway", "railway deploy this", "railway logs", "tail railway logs", "why is my railway service crashing", "why did the build fail on railway", "railway 500s", "railway latency", "show railway http logs", "redeploy on railway", "restart my railway service", "roll back railway", "set a railway env var", "list railway variables", "railway metrics", "is my railway service healthy", "connect to my railway postgres", "ssh into railway", "run this locally with railway env", "list railway projects/services/deployments", and (Onsager-specific) "check railway", "preflight", "smoke test", "is the deploy healthy".
Guides cybersecurity asset modeling, inventory, and vulnerability assessment using MITRE D3FEND. Covers asset inventory (hardware, software, network, data, containers), network mapping, vulnerability enumeration, dependency mapping, and operational risk assessment. Use when building CMDBs, running asset discovery, mapping network topology, assessing vulnerabilities, or modeling organizational cyber posture—not for hardening controls (d3fend-harden), detection engineering (d3fend-detect), or incident response (d3fend-evict).
Create optimized Docker containers with multi-stage builds, security best practices, and minimal image sizes. Use when containerizing applications, creating Dockerfiles, optimizing container images, or setting up Docker Compose services.
Advanced log analysis for Docker containers using signal extraction.
Generate optimized Docker images for Bun applications. Use when deploying to containers, minimizing image sizes, setting up CI/CD pipelines, or deploying to Kubernetes.
Deploy containers on ECS and Fargate. Configure task definitions, services, and load balancing. Use when running containerized workloads on AWS.
Docker containerization for development and production. Covers Dockerfiles, multi-stage builds, layer caching, Compose services, networking, volumes, health checks, security hardening, and production deployment patterns. Use when writing Dockerfiles, optimizing image size, configuring Compose services, debugging container networking, setting up health checks, hardening containers for production, or troubleshooting build cache issues.
Use when building charts, data visualisations, or dashboards with Recharts. Also use when integrating Recharts with HeroUI, reviewing chart components, or creating responsive chart containers. Generates Recharts charts styled with HeroUI v3 design tokens and Tailwind CSS v4.
Web animations with Motion (formerly Framer Motion) for React -- gestures, scroll effects, spring physics, layout animations, SVG, micro-interactions, loading states. Use when: drag-and-drop, scroll animations, modals, carousels, parallax, page transitions, hover effects, staggered lists, loading spinners, number counters. Troubleshoot: AnimatePresence exit, list performance, Tailwind conflicts, Next.js "use client", layout in scaled containers.
Executes comprehensive health checks and generates status reports for network infrastructure services. Verifies Docker containers, validates Caddy reverse proxy, checks Pi-hole DNS, confirms Cloudflare Tunnel connectivity, and validates SSL certificates. Use when verifying infrastructure status, diagnosing connectivity issues, checking service health, or troubleshooting network problems. Triggers on "check health", "infrastructure status", "is everything running", "diagnose network", "service health", or "verify SSL".
Apply modern Swift language patterns and idioms for non-concurrency, non-SwiftUI code. Covers if/switch expressions (Swift 5.9+), typed throws (Swift 6+), result builders, property wrappers, opaque and existential types (some vs any), guard patterns, Never type, Regex builders (Swift 5.7+), Codable best practices (CodingKeys, custom decoding, nested containers), modern collection APIs (count(where:), contains(where:), replacing()), FormatStyle (.formatted() on dates, numbers, measurements), and string interpolation patterns. Use when writing core Swift code involving generics, protocols, enums, closures, or modern language features.
Cross-cutting infrastructure security audit skill that checks cloud infrastructure, DNS, TLS, endpoints, access control, network security, containers, CI/CD pipelines, secrets management, logging, and physical security against ALL major compliance frameworks. Use for infrastructure audit, cloud security audit, infrastructure compliance, DNS security audit, TLS audit, endpoint security, access control audit, network security assessment, infrastructure security, cloud compliance, Vanta alternative, compliance automation, security posture assessment, hardware security keys, YubiKey compliance.
