For examples and defaults, see [Connectors](/langsmith/managed-deep-agents-connectors). - -### Schedules - -Declare managed cron schedules under `schedules/`. Each direct child schedule file must export a named `schedule` declaration from `defineSchedule(...)` or `define_schedule(...)`. - -Deploy extracts schedule declarations from static literals, arrays, objects, and top-level literal constants. A schedule can deliver its final response to a configured Slack channel with `deliver_to` / `deliverTo`. After the deployment reaches `DEPLOYED`, `mda deploy` replaces the existing managed LangSmith cron jobs with the current local schedule declarations. For examples and constraints, see [Schedules](/langsmith/managed-deep-agents-schedules). - -### Sandbox - -To configure a managed sandbox, export `sandbox` from `sandbox/index.ts` for TypeScript or `sandbox/__init__.py` for Python. Scope defaults to one sandbox per thread; `scope: "agent"` shares one across the agent process. `sandbox/setup.sh`, when present, runs once when a new managed sandbox is provisioned. - -For configuration examples and lifecycle behavior, see [Configure a sandbox](/langsmith/managed-deep-agents-deploy#configure-a-sandbox). - -### Evals - -Put Harbor-style eval tasks under `evals/`. Each task directory includes `instruction.md`, `task.toml`, an `environment/` image, and a `tests/test.sh` verifier. When the project declares [identity](/langsmith/managed-deep-agents-identity), each task also needs `identity.json`. - -`mda init` scaffolds starter evals under `evals/`. For existing projects, use `mda evals init`. Compile a Harbor handoff with `mda evals compile`, then run trials with Harbor. Artifacts land under `.mda/evals/` and are not part of the deploy archive. For the full workflow, see [Evals](/langsmith/managed-deep-agents-evals). - -### Ignored paths - -The project loader skips these directories: - -```text -node_modules, .git, .mda, .deepagents, memories, dist, build -``` - -It also skips `.env` and `.env.*` files when copying files into the compiled build. `mda dev` stages the root `.env` into `.mda/build/.env` for local development only; deploy still forwards non-reserved `.env` entries as hosted secrets instead of archiving the file. - -## Agent definition reference - -`define_deep_agent` and `defineDeepAgent` accept the full Deep Agents `create_deep_agent` configuration surface except the managed keys.

Threads are always user-owned. Without identity, the deployment uses shared agent memory. - -Scheduled runs choose their thread behavior explicitly. An ephemeral thread is cleaned up after the run, while a persistent thread reuses a stable thread ID so state accumulates. For the thread modes and when to use each, see [Schedules](/langsmith/managed-deep-agents-schedules). - -## Sandboxes - -A [sandbox](/langsmith/sandboxes) gives the agent an isolated environment for code execution and filesystem work. Configure one by exporting `sandbox` from `sandbox/index.ts` or `sandbox/__init__.py`, and use `sandbox/setup.sh` to provision it the first time it is created. Sandboxes default to one per thread; set `scope` to `agent` to share one across the agent process. Connectors can also provision files, CLIs, and credentials when a sandbox starts. For configuration options and examples, see [Configure a sandbox](/langsmith/managed-deep-agents-deploy#configure-a-sandbox). - -## Connectors - -Optional modules directly under `connectors/` extend the agent with external tools and capabilities. Discovery is name-agnostic: each file is a connector, and you do not register connectors in the agent entry. The runtime loads each connector when it compiles and starts the deployment: - -- **MCP** (`connectors/mcp.{py,ts}`): the runtime creates the MCP client, loads tools from the declared remote servers, and appends them to the authored tools at runtime. -- **LangSmith** (`connectors/langsmith.{py,ts}`): the runtime mounts one HTTP route per capability on the Agent Server and runs each call server-side with the workspace key, so untrusted callers never receive `LANGSMITH_API_KEY`. Requires a root identity declaration. -- **GitHub** (`connectors/github.{py,ts}`): when the project declares a sandbox, the runtime clones the configured repositories, installs the `gh` CLI, and injects credentials as the sandbox starts. - -For authoring, defaults, and provider setup, see [Connectors](/langsmith/managed-deep-agents-connectors). - -## Provider events - -The Slack and GitHub connectors can mount public provider Events URLs on the Agent Server (for example Slack at `POST /connectors/slack/events`, or GitHub at `POST /connectors/github/events`).

That is fine for a personal prototype. It breaks as soon as real users show up: - -| What goes wrong | Example | -| --- | --- | -| **Shared memory** | Alice asks the agent to remember her API preferences. Bob opens a new chat and the agent already "knows" Alice's details. | -| **Wrong credentials** | The agent calls GitHub or another API with one shared token, so every user acts as the same account, or you have no safe way to act *as* the signed-in user. | - -Deep Agents without identity keep durable memory and call tools on the user's behalf. Identity turns "who is calling?" into enforced isolation instead of hoping the prompt or the UI keeps people apart. - -A key benefit of identity is that downstream tool calls can act **as the signed-in user** rather than as a shared bot account. For example, with user-scoped credentials, the agent calls GitHub as Alice, not as a single bot token shared across all users. - -For deployments with compliance requirements such as SOC 2, GDPR, or HIPAA, identity scoping provides the data segregation boundaries that auditors expect: each caller's memory and credentials are isolated, and `runtime.identity` gives you an audit trail of who triggered each run. - -Adding identity to a project that previously had none does not delete existing threads or memory. Existing memory remains in Context Hub, and new runs use the memory slices from your identity declaration. Threads are always user-owned; identity scope controls memory and credentials. - - -## Understand three core concepts - -Learn these three concepts before you write any identity config: - -| Idea | Plain meaning | Example | -| --- | --- | --- | -| **User** | The person or service this run is for | `user_123`, a GitHub login, a guest id | -| **Auth** | How the runtime learns who is calling for this request | Your backend sends identity headers, or the browser sends a verified login token | -| **Scope** | Which memory slices and credentials the run can use | Per-user memory and credentials, shared agent memory, or no managed memory | - -A few important clarifications: - -- **User** is not the agent. It is the caller the run represents, and it can be a person or a service (`user.kind`). -- **Organization-scoped identity is not supported**. The runtime ignores organization headers, and `define_identity(...)` rejects organization scopes. -- **Fail closed** means the runtime rejects any request that is missing a required user. It never falls back to shared memory. - -From the authenticated user, Managed Deep Agents derives two scoped outcomes: - -- **Memory**: which durable [Context Hub](/langsmith/managed-deep-agents-memory) slices the run can see -- **Credentials**: whose token the agent uses for downstream tool calls, the signed-in user, one shared agent token, no token, or a custom resolver - -```mermaid -flowchart LR - Caller["Caller"] --> Auth["Auth authenticates request"] - Auth --> Resolve["Resolve user"] - Resolve --> Scope["Scope memory and credentials"] - Resolve --> Reject["Reject: 403"] - Scope --> Run["Run agent with runtime.identity"] - - classDef process fill:#E5F4FF,stroke:#006DDD,stroke-width:2px,color:#030710; - classDef trigger fill:#F6FFDB,stroke:#6E8900,stroke-width:2px,color:#2E3900; - classDef output fill:#EBD0F0,stroke:#885270,stroke-width:2px,color:#441E33; - classDef alert fill:#F8E8E6,stroke:#B27D75,stroke-width:2px,color:#634643; - class Caller trigger; - class Auth,Resolve,Scope process; - class Run output; - class Reject alert; -``` +## Add identity -## Choose a scope - -`scope` is the isolation boundary for memory and credentials.

The runtime mounts enabled memory slices under `/memories/agent/` and `/memories/user/` (hot `AGENTS.md` files plus optional cold files). Deploy syncs `instructions.md` and `skills/**`, but preserves existing `memories/**` and does not overwrite runtime-created memory. Set `disableMemory: true` or `disable_memory=True` to disable managed memory. For more information about hot/cold tiers and identity remounts, see [Memory](/langsmith/managed-deep-agents-memory).
