sofagent is an open-source FDE Harness for AI coding agents — on entry, write your business judgment into files (workflows, ontology, AI nodes); after departure, audit every change against them. 25 codified audit rules, tamper-evident chain, snapshots, and an MCP toolset (104 tools, 11 plugins). Everything can be FDEing.
DeepSeek Harness (DSH) plugin: a read-only ledger for the plugins you already have installed — a capability inventory with file:line evidence, declared-vs-detected reconciliation, cross-profile version drift, and a diff of what changed since the last scan.
The deny-by-default governance kernel for AI agents — permissions, L0–L4 guardrails, human approvals and an immutable audit chain as an Apache-2.0, framework-neutral library. Gate LangGraph / CrewAI / n8n / Dify or plain scripts in three lines.
