���� Description

Summary

Reorganizes the deepagents and langchain docs around the four-component harness framework introduced at Interrupt 2026.

New: langchain/harness.mdx

A new page in the LangChain Core components section that establishes the conceptual foundation:

  • agent = model + harness framing: the harness is the capability layer (tools, execution environment, context management, delegation, steering) that turns a model loop into a deep agent
  • create_agent positioned as the minimal, opt-in harness—extensible via middleware
  • Full capability matrix across 6 categories (execution environment, context management, planning & delegation, fault tolerance, guardrails, steering)
  • Progressive create_agent + middleware example building a research assistant layer by layer
  • Tip linking to create_deep_agent as the pre-assembled harness for deep agents

Updated: deepagents/harness.mdx

Restructures the existing page around the same four components:

  • Replaces flat capability list with a summary table linking to each component section
  • Four H2 sections: Execution environment, Context management, Delegation, Steering
  • Skills, memory, and summarization moved under Context management
  • Planning (write_todos) and subagents moved under Delegation

Updated: deepagents/customization.mdx

  • New overview table at the top grouping every create_deep_agent parameter by harness category
  • Links to langchain/harness for custom composition from scratch
  • Expanded Profiles section intro (what profiles are for, what they can carry)
  • Simplified ## Advanced section to a one-line pointer to langchain/harness

Updated: deepagents/overview.mdx

  • Adds the four-component table early so users see the framework on first landing

Updated: langchain/agents.mdx

  • Adds a bridge paragraph connecting the agent loop to the harness concept, with a link to langchain/harness

Cross-references fixed

  • Three pages linked to #planning-capabilities (removed in restructure); updated to #task-planning
