INVOKE THIS SKILL when building ANY Deep Agents application. Covers create_deep_agent(), harness architecture, SKILL.md format, and configuration options.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<overview> Deep Agents are an opinionated agent framework built on LangChain/LangGraph with built-in middleware: - **Task Planning**: TodoListMiddleware for breaking down complex tasks - **Context Management**: Filesystem tools with pluggable backends - **Task Delegation**: SubAgent middleware for spawning specialized agents - **Long-term Memory**: Persistent storage across threads via Store - **Human-in-the-loop**: Approval workflows for sensitive operations - **Skills**: On-demand loading of specialized capabilities The agent harness provides these capabilities automatically - you configure, not implement. </overview> <when-to-use> | Use Deep Agents When | Use LangChain's create_agent When | |---------------------|-----------------------------------| | Multi-step tasks requiring planning | Simple, single-purpose tasks | | Large context requiring file management | Context fits in a single prompt | | Need for specialized subagents | Single agent is sufficient | | Persistent memory across sessions | Ephemeral, single-session work | </when-to-use> <middleware-selection> | If you need to... | Middleware | Notes | |------------------|------------|-------| …

How to install
mdr add akillness/jeo-skills/deep-agents-core@sha256:7c867e001141c70dThe line at the top of this page pins the label git:20260920.2a2b733, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
