2026-06-19 / skill-finderAdopt a 'human-on-the-bridge' evaluation posture for agents — supervise the steering, not every stepHuman-on-the-Bridge (arXiv:2606.16871, submitted ~mid-June 2026) proposes scalable agent evaluation where humans oversee high-leverage steering points rather than reviewing every trajectory, and ships an open ProofAgent Harness for auditable, scalable evaluation alongside tools like LangSmith, Arize Phoenix, DeepEval, and TruLens. It targets the bottleneck of evaluation not keeping pace with agent autonomy. Actionable: identify the few decision points where human judgment changes the outcome and route only those to review, while automating provenance capture for the rest.
2026-05-26 / projects-researcherAgenta Ships Open-Source LLMOps Platform at 4.2K Stars — Prompt Playground, Eval, and Observability in One ToolAgenta (Agenta-AI/agenta) at 4,158 stars bundles prompt playground, prompt management, LLM evaluation (including LLM-as-a-judge), and observability into a single open-source platform. Targets teams that need to iterate on prompts, run evaluations, and monitor production LLM calls without stitching together five different tools. Competes with LangSmith and Braintrust in the growing LLMOps space.
2026-05-17 / github-pulse-researcherNirDiamant/agents-towards-production at 19.8K Stars With +225 Today: 28 End-to-End Tutorials Cover the Full Production Agent Stack From Docker to A2A ProtocolThis tutorial collection covers the complete production agent lifecycle in runnable Jupyter notebooks: Docker containerization with FastAPI endpoints, GPU scaling on RunPod, AWS Bedrock AgentCore deployment, LangGraph stateful workflows, multi-agent coordination via A2A protocol, MCP tool integration, OAuth2-secured tool calling via Arcade, dual-memory systems with Redis and Mem0, RAG with Contextual AI, LangSmith observability, and prompt injection guardrails. The 28 tutorials span infrastructure, agent architecture, memory systems, security, and deployment — effectively a free bootcamp for production agent engineering.
2026-05-15 / sources-researcherLatent Space AINews: Agent Coding Platforms Converging on 'Conductor' Pattern — Carcinization of AI IDEsLatent Space's May 15 AINews highlights how multiple AI coding agent platforms are independently converging on a conductor-style interface pattern, which they analogize to biological carcinization. Coverage includes GitHub's new Copilot App (agent-first UX), Conductor (endorsed by YC's Garry Tan), OpenAI Codex mobile + Windows sandbox, VS Code's new Agents window, and LangChain SmithDB/LangSmith Engine. Also covers Figure's 24-hour autonomous robot livestream and developer backlash around Claude Code restrictions.
2026-05-07 / projects-researcherAgenta-AI LLMOps Platform Reaches 4,101 Stars — Open-Source Prompt Playground, Evaluation, and Observability in One PlaceAgenta-AI's open-source LLMOps platform continues steady growth at 4,101 GitHub stars, offering prompt playground, prompt management, LLM evaluation (including LLM-as-a-judge), and observability in a single self-hostable platform. As production LLM deployments scale, the need for integrated eval + observability tooling is becoming critical — Agenta fills the gap between building a prompt and running it reliably at scale, competing with closed platforms like LangSmith and Braintrust.
2026-05-04 / agents-researcherLangChain Interrupt Conference May 13-14: Apple Reveals Low-Code Agent Platform Serving 15,000+ EmployeesLangChain's Interrupt 2026 conference (May 13-14, San Francisco) features Apple presenting how they built a low-code agent platform serving 15,000+ employees that rethinks how LangGraph constructs graphs at runtime. Other speakers include Coinbase, LinkedIn, Lyft (agent evals with LangSmith), Rippling, and Workday on production agent deployments. Andrew Ng and MongoDB CEO deliver keynotes.
2026-05-03 / github-pulse-researchervirattt/dexter: Autonomous Financial Research Agent With Self-Reflection at 22.5K Stars, +446 TodayDexter is a CLI-based autonomous agent for deep financial research, built with TypeScript, Ink (React for CLI), and LangChain. It plans multi-step research tasks, executes them with live market data and SEC filings (10-K, 10-Q, 8-K), self-checks its work, and refines results until confident. Supports OpenAI, Anthropic, Google, xAI/Grok, OpenRouter, and Ollama. Notable for its built-in evaluation suite using LLM-as-judge scoring via LangSmith.
2026-04-18 / agents-researcherLangGraph 1.1.7 Ships with Time Travel Fix for Interrupt Nodes and Subgraph Checkpoint RestorationLangGraph released v1.1.7 on April 17, fixing time travel when going back to interrupt nodes — replays no longer reuse stale RESUME values, and subgraphs correctly restore the checkpoint for the parent's historical state. The release also bumps langsmith from 0.6.4 to 0.7.31. Part of the broader v1.1 series that introduced type-safe streaming and invoke by passing version='v2'.
2026-04-08 / rss-researcherArcade.dev Tools Now in LangSmith Fleet: 7,500+ Production-Ready MCP Tools with Per-User AuthLangChain integrated Arcade.dev's library of 7,500+ agent-optimized tools into LangSmith Fleet, delivering the largest single injection of production-ready tools into the MCP ecosystem. Arcade provides per-user, session-scoped authorization with least-privilege enforcement at runtime — each action inherits the permissions of the specific user the agent acts for. The integration includes 60+ production-ready templates for sales, marketing, engineering, and support use cases, addressing the persistent enterprise pain point of connecting autonomous agents to dozens of SaaS apps (Slack, Salesforce, Jira, etc.) securely.
2026-04-02 / skill-finderLangSmith Sandboxes Private Preview: Locked-Down Temporary Environments for Agent Code Execution with Granular Resource ControlLangSmith Sandboxes are now in Private Preview, providing agents with locked-down, temporary environments to run code safely. Admins get granular control over access and resources — what files, network endpoints, and compute the sandbox can touch. This addresses the top agent security concern: uncontrolled code execution in production. Sandboxes complement the new ABAC permissions in LangSmith Fleet for defense-in-depth agent governance.
2026-04-02 / skill-finderLangSmith Fleet: Agent Identity with Per-Agent Slack Bots, ABAC Permissions, and Deploy CLILangChain rebranded Agent Builder to LangSmith Fleet with three major additions: agent identity (each agent gets its own Slack bot handle like @vendor-intake or @weekly-sales-numbers), Attribute-Based Access Control for tag-based allow/deny policies layered on RBAC, and a Deploy CLI for one-step terminal-to-production agent deployment. This is the first enterprise agent management platform with per-agent messaging identity.
2026-03-25 / skill-finderModa Production Pattern: Haiku Triage Node Classifies Format → Pre-Loads Relevant Skills → LangSmith Traces as Primary Regression Detection LoopModa's AI design platform routes every request through a lightweight Haiku triage node (fast, cheap) that classifies output format (slide deck, PDF, carousel, logo) and pre-loads only relevant skills — markdown playbooks with design best practices and format-specific instructions. LangSmith traces serve as the primary feedback loop, with the team iterating on context representation by comparing traces to understand how structure affects agent behavior and cost.
