📄 Description

Summary

Adds documentation for the hindsight-langgraph package — an open-source (MIT) long-term memory engine integration for LangChain and LangGraph agents.

Hindsight gives agents the ability to store, recall, and synthesize memories across conversations using four parallel retrieval strategies (semantic, BM25, graph traversal, temporal).

Pages added

  • Provider page (providers/hindsight.mdx): Overview, local setup (Docker/pip), installation, and links to component pages
  • Tools page (tools/hindsight.mdx): create_hindsight_tools() — retain/recall/reflect tools for agent-driven memory, plus LangGraph nodes for automatic memory injection
  • Store page (stores/hindsight.mdx): HindsightStore — drop-in BaseStore replacement for InMemoryStore with semantic search

Index updates

  • Added Hindsight card to stores/index.mdx
  • Added Hindsight card to tools/index.mdx
  • Added Hindsight card to providers/all_providers.mdx

Package details

Test plan

  • Verify all three pages render correctly
  • Verify internal links resolve (/oss/integrations/tools/hindsight, /oss/integrations/stores/hindsight, /oss/integrations/providers/hindsight)
  • Verify cards appear in tools index, stores index, and all providers listing
  • Run make broken-links to check for broken links
