🚀 Announcing LangSmith Skills + CLI 🚀 Agent improvements are increasingly driven by coding agents themselves. We're releasing LangSmith Skills alongside the LangSmith CLI to make coding agents experts at the agent engineering lifecycle. LangSmith Skills enable agents to debug traces, create datasets, and run experiments - and thanks... show more

@hwchase17 piping LangSmith traces directly into your coding agent so it debugs your other agents — agents improving agents is a literal workflow now. CLI-first was the right call

Sadi Moodi7 months ago

This is the future of agent engineering. Key insight: when agents can debug their own traces via CLI, you get compounding improvements. My checklist for agentic workflows: 1) instrument every step with trace IDs, 2) build feedback loops where agents learn from failed runs, 3) keep agents in terminal where they're most productive. The 50% VRAM reduction from Unsloth + LangSmith = serious edge deployment potential.

Nice

danfiru7 months ago

the toolchain is eating itself. agents improving agents. the question is whether this feedback loop converges on better software or just more software. best stacks will be the ones that know when to stop generating.

check out to get sqry, ships as an MCP server (33 tools). Claude Code, Codex, Gemini can query the actual call graph instead of guessing. make @LangChain smarter.

Gonna try it Looks good

Thank you! I was making do with the locally hosted MCP server and it was quite finicky.

Agents improving agents via traces + CLI feels like the toolchain finally eating itself in the best way. One thing I'm wondering: how are you all thinking about stopping conditions or 'convergence' in these self-improvement loops so it doesn't just keep generating more code forever?

Vikas Kumar | Agent Engineer7 months ago

We're getting closer to agents running the full engineering loop: build → debug → eval → improve.

Chris Ruppelt7 months ago

Awesome, would be cool to get some example usages. How do i get claude code running to fix a specific langgraph call given the langsmith run/trace id?

VibeCodes7 months ago

Agents improving their own traces via CLI is a huge step. Self-improving workflows > one-shot execution. We're building on this vision at @getvibecodes — AI agents as persistent team members across the full dev lifecycle. LangSmith Skills makes the ecosystem stronger for everyone.

Today, we’re shipping new ways to observe, analyze, and debug agents with LangSmith: • Polly: an AI assistant for AI engineering that helps you understand traces, threads, and improve prompts • LangSmith Fetch: a CLI for pulling trace & thread data straight into your terminal or coding agent Agents are running longer and getting more complex, which demands new debugging workflows beyond simple LLM apps. We wrote a blog on the trends behind this shift— and why tools like Polly and LangSmith Fetch are needed. Shipping reliable agents requires full visibility into agent behavior, with tooling that helps you reason over that data in the UI, the terminal, or alongside coding agents. 📔Learn more about Polly: 📔Learn more about LangSmith Fetch: 📔How to observe deep agents: 📽️ Polly video tutorial: 📽️ LangSmith Fetch video tutorial:

UI Skills are now easier for agents. Introducing UI Skills CLI. ask Codex, Cursor, Claude Code, or any agent to use the CLI, like: "use `npx ui-skills start` to fix the motion in this dialog" it finds the best design-engineering skill for the job and uses it as context

Our latest LangChain Academy course – Building Ambient Agents with LangGraph – is now available! Most agents today handle one request at a time through chat interfaces. But as models have improved, agents can now run in the background – and take on long-running, complex tasks. LangGraph is built for these “ambient agents,” with support for human-in-the-loop workflows and memory. LangGraph Platform provides the infrastructure to run these agents at scale, and LangSmith helps you observe, evaluate, and improve your agents. Together, they make it easier to build reliable, production-ready agents. In this course, you’ll: 📩 Learn the fundamentals of LangGraph and how to build your own email agent 📊 Evaluate your agent using LangSmith ✅ Add human-in-the-loop for reviews, and memory so your agent adapts over time 🚀 Deploy your agent with LangGraph Platform and connect it to Gmail
