Deep Agents Managed Deep Agents v0.9: schedules, per-run configuration, and Slack reactions October 7, 2026 4 min Go back to blog Create agents Create agents Key Takeaways Agent-created schedules: agents can set up reminders and recurring tasks from a conversation. Per-run configuration: one deployment can pick its model, skills, and tools for each run. Slack reactions: agents acknowledge messages before they reply. Today we're releasing Managed Deep Agents v0.9, with new capabilities that let agents schedule their own follow-ups, reconfigure themselves on every run, and react to Slack messages. These updates make it easier to build internal agents that live in Slack or your own channels and work more like teammates. Let agents schedule their own work The new Schedules SDK lets agents create reminders, follow-ups, and recurring tasks mid-conversation, so they can handle requests like "Remind me about this tomorrow." The agent creates the schedule itself during a conversation, the schedule runs as the person who asked using their set of permissions and connections, and results come back to the same channel. Create a schedule from inside a run: await schedules.create(owner={"type": "user"}, cron="0 9 * * 1-5", timezone="America/Los_Angeles", prompt="Write the daily digest.") It’s most useful behind a tool, so your agent’s users can create, list, update, and delete schedules just by chatting. Here’s a reminder tool: from langchain.tools import tool from managed_deepagents import schedules @tool async def remind_me(prompt: str, cron: str, timezone: str = "UTC") -> str: """Run a prompt for the current user on a cron schedule.""" item = await schedules.create( owner={"type": "user"}, cron=cron, timezone=timezone, prompt=prompt, ) return f"Created schedule {item['id']}." The agent passes a prompt and a cron expression, and each time the cron fires, LangSmith starts a new run with that prompt. Schedules inherit the channel they were created in, so results post back where the request came from: a weekday reminder requested in Slack posts a new message to that conversation on every run. One-time schedules (at instead of cron) reply in the original thread, which suits follow-ups like "check on this deploy in an hour." Configure agents per run An agent can now be configured dynamically per run. Set up the agent as a callable function: it receives the runtime at the start of each run and returns a define_deep_agent definition, choosing the model, instructions, skills, MCP servers, and sandbox for that run. Instead of maintaining a near-copy of the same agent for every team or repo, you run one deployment. This enables your deployment to operate more flexibly, in which a single agent deployment can be customized for different teams or use cases based on the context, such as the channel or user that originates the request. Say one internal Slack agent serves several teams. Your agent function can check which channel a run came from and load billing skills for finance, or an incident-response MCP server for the platform team. That’s different from instructions telling the model when to use a skill: the configuration is set before the model runs, so the agent never sees skills or MCP tools outside its configuration. That keeps its context small, doubles as access control, and lets you pick the model itself, which the model can’t do. In general, it prevents non-deterministic outputs where the model is tasked with choosing the toolkit in cases where we know exactly what set of tools should be available to the agent. The same idea works for a coding agent that loads different skills and a cheaper or more capable model for each repository: # agent.py: one coding agent, configured per repo at the start of each run from dataclasses import dataclass from managed_deepagents import ManagedServerRuntime, define_deep_agent REPOS = { "payments-service": { "model": "openai:gpt-5", "instructions": "Python service. Run pytest before opening a PR.", "skills": ["./skills/python-service"], }, "storefront": { "model": "openai:gpt-5-mini", "instructions": "Next.js app. Run web tests and an a11y check before opening a PR.", "skills": ["./skills/typescript-web"], }, } @dataclass class AppContext: repository: str = "" def agent(runtime: ManagedServerRuntime[AppContext]): execution = runtime.execution_runtime context = execution.context if execution is not None else None repo = context.repository if context is not None else None config = REPOS.get(repo, REPOS["storefront"]) return define_deep_agent(name="open-swe", context_schema=AppContext, **config) The function reads runtime.execution_runtime.context and falls back to a default when there is none, such as on channel runs or when Agent Server loads the agent to read its schema. Callers pick the configuration with the run’s context: # Same deployment, different repo: just change the run context await client.runs.create( thread_id, "open-swe", input={"messages": [{"role": "user", "content": "Fix the flaky refund test."}]}, context={"repository": "payments-service"}, ) React to Slack messages Slack reactions show the sender right away that the agent picked up their message, even while it spends a while reasoning and calling tools before it replies. Reactions are on by default (👀), and the new reactions option on your Slack channel lets you turn them off, pick another emoji, or choose one per message. This example uses 🐛 when a message mentions something broken, and 👀 otherwise: from managed_deepagents import channels async def choose_emoji(context: dict) -> str: return "bug" if "broken" in context["text"].lower() else "eyes" channel = channels.slack(name="Support Bot", reactions=choose_emoji) Reactions can be simple. However, it is possible to configure your reaction response with a function that calls a model to pick a more precise emoji. A decision model like Jev keeps that fast and cheap; the Slack channel docs walk through a full example. Getting started Managed Deep Agents v0.9 is available in Public Beta today.
