Show HN: Provena: Open-Source Library for AI Agent Context Governance

https://github.com/rajfirke/provena
2•rfirke•10h ago
Looking for contributors! We have 7 contributors and We have 11 "good first issue" labels and 17 "help wanted" issues. All well-scoped with code examples.

Project: Nobody governs the context input layer. Tools exist to govern what agents DO (Microsoft AGT), what agents SAY (Guardrails AI), and how agents COMMUNICATE (NeMo). But the data flowing INTO the context window — retriever results, tool outputs, agent messages — is completely ungoverned. That's what Provena fixes
