Feature Request: Kevros Governance Tool Integration

Description

Governance-as-a-service tools for LangChain agents. Verify actions before executing, create tamper-evident audit trails, and generate compliance evidence bundles.

Tools

  • GovernanceVerifyTool — Verify action against policy bounds (ALLOW/CLAMP/DENY)
  • GovernanceAttestTool — Create hash-chained provenance record
  • GovernanceBindTool — Bind intent to command cryptographically
  • GovernanceVerifyOutcomeTool — Verify action achieved its intent
  • GovernanceBundleTool — Generate compliance evidence package

Integration Code

Already built and tested: https://github.com/ndl-systems/kevros-governance-sdk/blob/main/kevros_tools.py

```python from kevros_tools import get_governance_tools

tools = get_governance_tools(api_key="kvrs_...") agent = initialize_agent(llm, tools + your_other_tools, ...) ```

Use Case

Any agent taking high-stakes actions (trades, deployments, data mutations) where you need to prove what the AI decided and why. EU AI Act, NYC Law 144, SEC/FINRA audit compliance.

Kevros Governance Tool Integration Fix Plan

Step 1: Install Kevros Governance SDK

pip install git+https://github.com/ndl-systems/kevros-governance-sdk.git

Step 2: Import Kevros Governance Tools

from kevros_tools import get_governance_tools

Step 3: Initialize Kevros Governance Tools

tools = get_governance_tools(api_key="kvrs_...")

Step 4: Integrate Kevros Governance Tools with LangChain Agent

agent = initialize_agent(llm, tools + your_other_tools, ...)

Step 5: Verify Action with GovernanceVerifyTool

governance_verify_tool = tools["GovernanceVerifyTool"]
action = {"intent": "trade", "params": {"amount": 100}}
result = governance_verify_tool.verify(action)
print(result)  # ALLOW, CLAMP, or DENY

Step 6: Create Hash-Chained Provenance Record with GovernanceAttestTool

governance_attest_tool = tools["GovernanceAttestTool"]
record = governance_attest_tool.create_provenance_record(action)
print(record)  # Hash-chained provenance record

Step 7: Bind Intent to Command Cryptographically with GovernanceBindTool

governance_bind_tool = tools["GovernanceBindTool"]
intent = {"intent": "trade", "params": {"amount": 100}}
signature = governance_bind_tool.bind_intent(intent)
print(signature)  # Cryptographic signature

Step 8: Verify Action Achieved Its Intent with GovernanceVerifyOutcomeTool

governance_verify_outcome_tool = tools["GovernanceVerifyOutcomeTool"]
outcome = {"result": "success"}
result = governance_verify_outcome_tool.verify_out
