Builds and debugs Letta Code channels, including first-party channel adapters and dynamic user channel plugins under ~/.letta/channels. Use when adding Telegram, WhatsApp, Bluesky, Slack, Discord, or custom channel support; testing channel routing, pairing, MessageChannel, runtime dependencies, or channel plugin manifests.
Configures AWS Transit Gateway: creating a hub and attaching VPCs, segmenting traffic with route tables, centralizing egress and inspection through a hub (appliances or a Gateway Load Balancer endpoint), forcing east-west traffic between VPCs through AWS Network Firewall, connecting on-premises networks over the transit-gateway side of a Site-to-Site VPN or Direct Connect attachment (including ECMP to aggregate bandwidth across multiple VPN tunnels), peering transit gateways across Regions, migrating from a VPC peering mesh, and routing IP multicast. Applicable when connecting many VPCs through one router, isolating environments, forcing VPC-to-VPC traffic through a central Network Firewall, reaching on-premises over the hub, linking Regions, or moving off a peering mesh. Not applicable for single-VPC routing, VPC peering between two VPCs (vpcpeering skill), Direct Connect gateway or virtual interface setup (directconnect skill), or Route 53 DNS work.
.NET 10 minimal APIs — the default for building HTTP endpoints. Covers MapGroup, endpoint filters, TypedResults, OpenAPI metadata, parameter binding, and route conventions. Load this skill when creating API endpoints, configuring routing, setting up OpenAPI documentation, or when the user mentions "endpoint", "MapGet", "MapPost", "MapGroup", "TypedResults", "route", "minimal API", "OpenAPI", "swagger", "rate limiting", or "output caching".
Train Mixture of Experts (MoE) models using DeepSpeed or HuggingFace. Use when training large-scale models with limited compute (5× cost reduction vs dense models), implementing sparse architectures like Mixtral 8x7B or DeepSeek-V3, or scaling model capacity without proportional compute increase. Covers MoE architectures, routing mechanisms, load balancing, expert parallelism, and inference optimization.
Expert skill for prompt engineering and task routing/orchestration. Covers secure prompt construction, injection prevention, multi-step task orchestration, and LLM output validation for JARVIS AI assistant.
Expert Coordinator pattern decisions for iOS/tvOS: when coordinators add value vs overkill, parent-child coordinator hierarchy design, SwiftUI vs UIKit coordinator differences, and flow completion handling. Use when designing navigation architecture, implementing multi-step flows, or decoupling views from navigation. Trigger keywords: Coordinator, navigation, flow, parent coordinator, child coordinator, deep link, routing, navigation hierarchy, flow completion
Execute real actions across 1000+ applications (Gmail, Slack, GitHub, Notion, etc.) using Composio's tool routing. Stop suggesting—start doing.
Async communication patterns using message brokers and task queues. Use when building event-driven systems, background job processing, or service decoupling. Covers Kafka (event streaming), RabbitMQ (complex routing), NATS (cloud-native), Redis Streams, Celery (Python), BullMQ (TypeScript), Temporal (workflows), and event sourcing patterns.
Route AI coding queries to local LLMs in air-gapped networks. Integrates Serena MCP for semantic code understanding. Use when working offline, with local models (Ollama, LM Studio, Jan, OpenWebUI), or in secure/closed environments. Triggers on local LLM, Ollama, LM Studio, Jan, air-gapped, offline AI, Serena, local inference, closed network, model routing, defense network, secure coding.
Implement LangGraph error handling with current v1 patterns. Use when users need to classify failures, add RetryPolicy for transient issues, build LLM recovery loops with Command routing, add human-in-the-loop with interrupt()/resume, handle ToolNode errors, or choose a safe strategy between retry, recovery, and escalation.
Use when committing code, managing branches, pushing to remote, creating pull requests, or performing version control operations. Conforms to packages/shared/schemas/skill-routing-value-standard.md.
Linux networking expert for iptables, nftables, routing, DNS, and network troubleshooting
