Expert guidance for Arcjet, the developer-first security platform that provides rate limiting, bot protection, email validation, and attack detection as a code-first SDK. Helps developers add security layers to Next.js, Node.js, and other JavaScript/TypeScript applications without managing infrastructure.

You are an expert in Arize and its open-source Phoenix library for AI observability. You help developers monitor LLM applications with tracing, evaluation, embedding analysis, drift detection, and retrieval quality metrics — using Phoenix for local development (open-source, self-hosted) and Arize platform for production monitoring at scale.

When the user wants to perform load testing or performance testing using Artillery with YAML-based scenario definitions. Also use when the user mentions "artillery," "YAML load test," "WebSocket testing," "Socket.io load test," "scenario-based load testing," or "artillery run." For JavaScript-based load testing, see k6.

You are an expert in Atuin, the Rust-based shell history tool that replaces your shell's built-in history with a searchable, syncable, context-aware database. You help developers set up fuzzy search across shell history, sync history across machines, filter by directory/host/session, and analyze command usage — turning shell history from a flat text file into a powerful productivity tool.

Implement tamper-evident audit logs for compliance (SOC 2, HIPAA, PCI DSS). Use when building compliance audit trails, tracking who did what and when, or implementing immutable event logs that satisfy regulatory retention requirements.

You are an expert in Auth.js (formerly NextAuth.js), the authentication library for web frameworks. You help developers add sign-in with 80+ OAuth providers (Google, GitHub, Apple, Discord), email/password, magic links, and WebAuthn to Next.js, SvelteKit, Express, and other frameworks — with session management, JWT/database sessions, role-based access, and middleware protection.

AWS Bedrock — fully managed foundation models on AWS infrastructure. Use when deploying AI in AWS-native environments, needing enterprise compliance (SOC2, HIPAA), running Claude, Llama, Titan, or Mistral on AWS, leveraging Knowledge Bases for RAG, or applying Guardrails for content safety.

Configure Amazon CloudFront for global content delivery. Set up distributions with S3 and ALB origins, define cache behaviors and TTLs, invalidate cached content, and use Lambda@Edge for request/response manipulation at the edge.

Build with Amazon DynamoDB for fast, scalable NoSQL storage. Design tables with partition and sort keys, create GSI and LSI for flexible queries, enable streams for change data capture, and apply single-table design patterns for efficient data modeling.

Testing strategies, patterns, and tools for robotics software. Use this skill when writing unit tests, integration tests, simulation tests, or hardware-in-the-loop tests for robot systems. Trigger whenever the user mentions testing ROS nodes, pytest with ROS, launch_testing, simulation testing, CI/CD for robotics, test fixtures for sensors, mock hardware, deterministic replay, regression testing for robot behaviors, or validating perception/planning/control pipelines. Also covers property-based testing for kinematics, fuzz testing for message handlers, and golden-file testing for trajectories.

Real-time face swap and video deepfake using a single source image. Use when: building face-swap applications, real-time video effects, virtual try-on features, AI video effects pipelines.

Create ZIP and TAR archives programmatically with Archiver — bundle files, directories, and streams into compressed archives with progress tracking. Use when tasks involve generating downloadable bundles, backing up directories, creating deployment packages, or building export features that zip multiple files together.

Argo CD for GitOps continuous delivery on Kubernetes. Use when the user needs to define applications declaratively, sync Kubernetes manifests from Git repositories, manage sync policies, and implement progressive delivery workflows.

Define runtime-validated types with ArkType — TypeScript's 1:1 validator. Use when someone asks to "validate data in TypeScript", "runtime type checking", "ArkType", "type-safe validation", "alternative to Zod", "faster validation library", or "validate with TypeScript syntax". Covers type definitions, validation, morphs (transforms), scopes, and comparison with Zod.

AssemblyAI API for speech recognition, transcription, and audio intelligence. Use when transcribing audio or video files, performing speaker diarization, running sentiment analysis on calls, detecting unsafe content in audio, or asking LLM-powered questions about recorded content with LeMUR.

Generate waveform visualizations from audio files. Use when a user asks to create waveform images, build audio player visualizations, generate waveform data for web players, create podcast episode previews, build audio thumbnails, render waveform PNGs for social media, extract peak data as JSON, or integrate waveform generation into audio processing pipelines. Covers audiowaveform CLI, JSON/binary data output, and web player integration.

When the user wants to set up authentication and authorization for a web application. Use when the user mentions "auth," "login," "OAuth," "SSO," "single sign-on," "role-based access," "RBAC," "permissions," "user roles," "access control," "authentication," or "authorization." Covers OAuth 2.0 provider integration, session management, and role/permission architecture. For JWT-specific tasks, see jwt-handler. For security review, see security-audit.

Feature-rich Stable Diffusion Web UI for image generation. Supports txt2img, img2img, inpainting, outpainting, LoRA, extensions, upscaling, and batch processing. Widely used desktop interface with an extensive extension ecosystem and API access.

AWS Command Line Interface for managing Amazon Web Services. Use when the user needs to interact with S3, EC2, Lambda, CloudWatch, IAM, and other AWS services directly from the terminal for operations, scripting, and automation.

Implement authentication with Amazon Cognito. Create user pools for sign-up and sign-in, configure identity pools for AWS access, handle JWT tokens, set up social federation with Google and Facebook, and secure APIs with Cognito authorizers.
