> langsmith

Monitor, trace, debug, and evaluate LLM applications with LangSmith. Use when a user asks to trace LLM calls, debug chain executions, evaluate AI output quality, set up LLM observability, monitor agent performance, run prompt experiments, compare model outputs, create evaluation datasets, track token usage and latency, or build LLM testing pipelines. Covers tracing, datasets, evaluators, annotation queues, prompt hub, and production monitoring.

> braintrust

You are an expert in Braintrust, the evaluation and observability platform for AI applications. You help developers run systematic evaluations, compare model versions, track experiments, log production traces, and measure quality metrics — with a focus on making AI development as rigorous as traditional software testing.

> prometheus-alertmanager

Configure Prometheus Alertmanager for alert routing, grouping, silencing, and notification delivery. Use when a user needs to set up alert receivers (Slack, PagerDuty, email), define routing trees, manage silences and inhibition rules, or troubleshoot alert delivery pipelines.

> envoy

You are an expert in Envoy, the high-performance C++ proxy designed for cloud-native applications. You help teams configure Envoy as an API gateway, service mesh sidecar, and load balancer using its L4/L7 routing, circuit breaking, rate limiting, TLS termination, gRPC support, and observability features — powering Istio, AWS App Mesh, and most modern service mesh implementations.

> helicone

LLM observability proxy that sits between your app and LLM providers. Logs every request, enables caching, rate limiting, and provides cost analytics. Works with OpenAI, Anthropic, and other providers with a one-line integration change.

> betterstack

Expert guidance for Better Stack (formerly Better Uptime + Logtail), the observability platform combining uptime monitoring, log management, incident response, and status pages. Helps developers set up comprehensive monitoring with alerting, on-call schedules, and public status pages.

> structlog-python

Add structured logging to Python with structlog. Use when a user asks to implement structured logging, add context to Python logs, configure log processing pipelines, or replace standard logging with typed output.

> falco

Expert guidance for Falco, the CNCF runtime security tool that detects anomalous behavior in containers and Kubernetes clusters using system call monitoring. Helps developers set up Falco for detecting shell spawns in containers, unexpected network connections, file access violations, and privilege escalation — all in real-time with zero application changes.

> uptime-robot

Monitor website uptime with UptimeRobot. Use when a user asks to monitor website availability, get alerts when a site goes down, create a public status page, or set up HTTP/ping/port monitoring.

> openai-agents

You are an expert in the OpenAI Agents SDK (formerly Swarm), the official framework for building multi-agent systems. You help developers create agents with tool calling, guardrails, agent handoffs, streaming, tracing, and MCP integration — building production-grade AI agents that coordinate, delegate tasks, and execute tools with built-in safety controls.

> railway-deploy

Manage Railway deployments using the CLI. Use when a user asks to deploy to Railway, check deployment status, manage Railway services, set environment variables on Railway, view Railway logs, link a Railway project, add a database on Railway, scale Railway services, manage Railway environments, rollback a Railway deployment, or run commands with Railway env vars. Covers the full deploy lifecycle from project setup to production monitoring.

> spring-boot

Spring Boot is a Java framework that simplifies building production-ready applications. It provides auto-configuration, embedded servers, and opinionated defaults for REST APIs, data access with JPA, security, and monitoring via Actuator.

> 3proxy

Deploy and configure 3proxy — a lightweight universal proxy server. Use when a user asks to set up HTTP, HTTPS, SOCKS4, SOCKS5, or transparent proxies, build proxy chains, configure authentication, set bandwidth limits, manage access control lists, set up proxy rotation, create multi-port proxy servers, configure logging and traffic accounting, or deploy a lightweight proxy without heavy VPN overhead. Covers all 3proxy features including proxy chaining, ACLs, traffic shaping, and multi-protocol

> linkerd

Linkerd lightweight service mesh for Kubernetes. Use when the user needs automatic mTLS, traffic splitting, retries, and observability with minimal resource overhead and operational complexity.

> sentry
