OnceMesh Open Source System Safely Reuses Exact LLM Agent Work
Critical_Molasses844 · reddit · 2026-08-25
The author released OnceMesh, an open-source system designed to avoid redundant expensive computations in LLM agent workflows (e.g., downloading sources, parsing documents). It identifies computations using every input affecting the result, storing outputs as content-addressed artifacts. It reuses results only after verifying authorization, freshness, provenance, and integrity. It is not a semantic prompt cache. The v0.1.0 alpha release supports private, organizational, and federated meshes, with adapters for LangGraph, LangChain, and LlamaIndex.
