Realm is an open-source AI Agent workflow engine that defines workflows via YAML, connects to external tools using the MCP protocol, and provides an evidence chain mechanism to ensure every output can be traced back to its real source.
Section 01
Realm is an open-source AI Agent workflow engine developed by Sensigo HQ, with its core design philosophy centered on "verifiability" as the first principle. It defines workflows via YAML, integrates the MCP protocol to connect to external tools, and provides an evidence chain mechanism to ensure every output can be traced back to its real source, aiming to address the credibility crisis of AI Agents.
Section 02
As LLM capabilities improve, AI Agents are evolving toward autonomously executing complex tasks, but autonomy brings trust issues: users find it hard to be confident in the accuracy of outputs and the compliance of execution processes. In enterprise scenarios like finance and healthcare, verifiability and auditability are essential needs, and Realm is a solution born to address this pain point.
Section 03
Realm uses declarative YAML to describe task sequences, with advantages including: high readability (understandable by non-technical personnel), version control (suitable for Git management), and ease of testing (independent verification of logic).
It implements the MCP standard proposed by Anthropic, standardizing interactions between LLMs and external tools. It can connect to databases, APIs, file systems, etc., and is not tied to any specific LLM provider.
Section 04
Realm's core innovation is the evidence chain mechanism, which generates tamper-proof audit logs for each workflow execution, including:
Section 05
As a unified knowledge retrieval system, it returns answers with cited sources and verification paths, solving the hallucination problem of traditional RAG systems.
Financial analysts can automatically generate research reports, with the evidence chain available for compliance teams to audit, ensuring data accuracy and completeness.
Handles complex customer requests (e.g., multi-system account issues), with traceable operations for quick problem localization in case of disputes.
Section 06
Realm's implementation highlights include:
Section 07
Realm is an open-source project. Its GitHub repository provides complete documentation, examples, and development guides, and uses a permissive license allowing commercial use. The community is developing extended tools: a visual workflow editor, pre-built tool sets, and integration adapters for LangChain/LlamaIndex.
Section 08
Realm represents the shift of AI Agents from maximizing capability to maximizing trustworthiness. The roadmap includes: support for distributed execution, fine-grained permission control, and blockchain integration to enhance the tamper-proof nature of the evidence chain. For technical decision-makers, Realm addresses the core question of "whether it's done correctly" and is a worthy option to consider.

Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
This project explores how to use Large Language Models (LLMs) to detect logical vulnerabilities in Ethereum smart contracts, especially business logic flaws that are difficult for traditional static analysis tools to capture, such as economic manipulation and execution order errors.
This article introduces an open-source project for building modern large language models from scratch. The project evolves from a GPT-2-style basic architecture to a Llama 2/3-style production-level implementation, covering complete tutorial implementations of key technologies such as RMSNorm, RoPE, SwiGLU, GQA, and MoE.
