New Chat Agent with Full Tool Access
LangSmith Agent Builder now includes an always-available Chat agent that can access every connected tool in your workspace—including Slack, Gmail, Linear, Pylon, and remote MCP servers. This eliminates the need to create specialized agents for one-off tasks. Users can ask natural language questions like "What are my open Linear tickets?" or "Summarize today's support requests," and the agent will plan, execute, and request approval before taking sensitive actions.
The Chat agent can orchestrate multiple tools in sequence. For example, you can ask it to summarize the last 10 emails, then automatically create calendar events for any meeting requests it finds. Multiple independent chat threads can run simultaneously, allowing users to manage multiple workflows and return to any conversation to approve actions or ask follow-up questions.
Convert Conversations Into Reusable Agents
A major workflow improvement lets you turn any chat conversation directly into a recurring agent with a single click. Rather than requiring prompt engineering or conditional logic, the conversation itself becomes the agent's setup. This pattern works particularly well for research, content writing, summarization, and outreach workflows. Created agents can be triggered manually, scheduled on a cadence, or configured to respond to external events like Slack messages or emails.
File Upload Capabilities
Users can now upload CSVs, images, and text files directly into chat for data analysis, image processing, and reference material. For example, uploading a CSV of sales data lets the agent analyze trends and share reports; uploading a screenshot enables conversion to formatted documents; importing style guides or existing prompts helps bootstrap new agent configurations.
Centralized Tool Management
A new workspace tool registry provides a single location to view all connected tools, authenticate new integrations, and manage remote MCP servers. Re-authentication needs are surfaced immediately. Only workspace administrators can add tools, providing governance controls while making new tools instantly available to all agents in the workspace.
