📄 Description

Adds langchain-collapse to the community middleware integrations table.

What it does

Preventive context management middleware that collapses consecutive read/search tool-call groups into a short placeholder, keeping only the most recent result. Reduces context usage before SummarizationMiddleware needs to fire.

  • 92% token reduction on realistic coding sessions
  • SummarizationMiddleware triggers 4.2x later when CollapseMiddleware runs first
  • Stateless, no LLM calls
  • PyPI · Source · CI
