AI Workflow Automation & Observability - N8N is an AI workflow builder that allows users to string together nodes into AI agents and set up external triggers for automated execution [1] - Langsmith is an AI observability and evaluation product designed to monitor the performance of AI applications [2] Integration & Setup - Connecting N8N to Langsmith requires generating a Langsmith API key and setting it in the N8N deployment environment [3][8] - Additional environment variables can be set to enable tracing to Langsmith, specify the trace destination, and define the project name [4] Monitoring & Debugging - Langsmith traces provide visibility into the workflow, including requests to OpenAI, model usage, latency, and token consumption [6] - Langsmith offers a monitoring view to track app usage, latency spikes, error rates, and LLM usage/spending [7]

Agent Architecture & Functionality - The Langchain deep research agent is highly configurable and open source, allowing for customization to specific use cases [1] - The agent operates in three main phases: scoping the problem, research, and report writing [3] - The research phase utilizes a supervisor to delegate tasks to sub-agents for in-depth research on specific subtopics [4] - Sub-agents use a tool calling loop, which can be configured with default or custom tools (like MCP servers) for searching flights, hotels, etc [17][18] - A compression step is used by sub-agents to synthesize research findings into comprehensive mini-reports before returning to the supervisor, mitigating context window overload [21][23] - The supervisor analyzes findings from sub-agents to either complete research or continue with follow-up questions [25] - Final report generation is done in a single shot using all condensed research findings [5][27] Implementation & Configuration - The agent is built on Langraph and can be run locally by cloning the Open Deep Research repository [29] - Configuration involves setting API keys for models (default OpenAI) and search tools (default Tavily) [30] - Langraph Studio can be used for iterating and testing the agent with different configurations [32] - The agent is highly configurable, allowing users to choose between default or model provider native search tools, connect to MCP servers, and select models for different steps [33][34] Application & Output - The agent can be used for complex research tasks, such as planning a trip, by iteratively calling tools and searching the web [2] - The agent provides a final report with an overview, flight options, transportation options, accommodation options with booking links, a sample itinerary, and a list of sources [36] - Open Agent Platform provides a UI to configure and try out the research agent without cloning the code [37]

Agentic Platform Engineering Implementation - Outshift by Cisco is redefining platform engineering with agentic platform engineering, aiming to automate workflows and allow platform engineers to focus on high-value work [1][2] - The company built Jarvis, a genai-powered multi-agentic system, to automate tasks and improve efficiency [2] - Langraph, combined with Langsmith's observability tools, enables debugging agentic applications and improving reasoning capabilities at scale [6] Efficiency Improvement - Implementing Jarvis allows developers to self-service through genai-powered automation, eliminating manual toil [4] - CI/CD pipeline setup time reduced from a week to less than an hour [7] - Resource provisioning time (e.g., S3 buckets, EC2 instances, access keys) reduced from half a day to nearly instantaneous [7] - The company has eliminated unnecessary back and forth between developers and SREs [7] Workflow Transformation - The company shifted from traditional automation to agentic reasoning-based workflows by adopting Langraph [5] - Developers interact with Jarvis for platform-related questions and configurations, retrieving information autonomously [8] - The new system allows the company to handle a higher volume of requests with the same team while reducing burnout [8] Technology Evaluation - Langraph's tight integration with Langsmith, especially for debugging and evaluations, is a significant advantage [9] - The company found Langraph to be superior compared to other agentic solutions or custom-built alternatives [9]
