NodeDex: A Reasoning Graph for Agent Decision Tracking

NodeDex: A Reasoning Graph for Agent Decision Tracking

Original: The memory we have now save the summary and Casual links to a certain extend, what about the reasoning behind it the cause and effect? So i built one myself

Short summary

Built NodeDex, a local reasoning graph that tracks agent decision histories, dead-ends, and the rationale behind each choice. Solves the silent failure mode where agents confidently re-propose decisions that were already tried and rejected. Open-source, MCP-integrated, works with Claude and other agents—demo in 60 seconds, no API key required.

  • •NodeDex tracks decision history with supersede edges to prevent stale decision re-proposal
  • •Designed for agents using MCP, works with Claude and other LLM-based agents
  • •Open-source AGPL, local SQLite, includes demo and honest limitation discussion

Generated with AI, which can make mistakes.
