LangChain Slashes 65% of Default Agent Harness: Why Less Prompt Means More Control

LangChain's Deep Agents v0.7 cuts default harness base input tokens by 65% — from 5,395 to 1,895 — by clearing the default system prompt, trimming tool descriptions 43%, and making TodoListMiddleware opt-in, backed by evaluations across GPT-5.6, Claude Opus 4.8, and GLM 5.2 showing no consistent accuracy gains from these components.

How Deep Agents Implements Skills: Progressive Disclosure & Middleware Ordering

This article analyzes Deep Agents' Skills implementation, revealing a three-layer progressive disclosure loading pattern where metadata loads at startup, full instructions load on activation, and resources load on demand. It explains how before_agent and wrap_model_call hooks inject skill metadata into system prompts, and why SkillsMiddleware positioning differs between main agents (early for coordination) and sub-agents (late for separation of concerns).
