A lightweight, zero-dependency SDK for cryptographically signing AI agent workflows.

governance-hash-sdk provides drop-in integrations for LangChain, LangGraph, and CrewAI to seal every agentic action with a Governance Hash. By generating an immutable SHA-256 audit trail, this SDK transforms opaque LLM executions into tamper-evident, enterprise-ready logs.

⚡ Why Use This SDK?

• Cryptographic Accountability: Seals each agent action with a Governance Hash (SHA-256).
• ISO/IEC 42001 Readiness: Satisfies clauses for AI Traceability and Risk Management.
• Zero Data Retention: Hashes generated locally. Raw prompts and PII never leave your servers.
• Policy-as-Code Enforcement: Validates agent decisions against predefined risk boundaries.

📦 Installation

Python (LangChain, CrewAI)

pip install governance-hash-sdk

TypeScript (LangChain.js)

npm install @scalar-os/governance-hash-sdk

🚀 Quick Start (LangChain)

from governance_hash_sdk.langchain import ScalarCallbackHandler

handler = ScalarCallbackHandler(agent_id="my_agent", policy_ref="ops-policy")
response = agent.run("Process refund $50", callbacks=[handler])
print(f"Hash: {handler.latest_hash}")
