Feature Description

Add a langchain-ai-identity partner package at libs/partners/ai-identity/ for agent governance. Provides per-agent cryptographic identity, fail-closed gateway enforcement, HMAC-SHA256 tamper-evident audit trails, and forensic session replay for LangChain agents. Components include AIIdentityGovernanceMiddleware, AIIdentityChatOpenAI (drop-in replacement), AIIdentityToolkit, AIIdentityCallbackHandler, and a create_ai_identity_agent factory function. 30 unit tests, published on PyPI as langchain-ai-identity 0.1.0.

Use Case

Teams deploying LangChain agents in regulated industries (finance, healthcare, legal) need forensic-grade evidence of what agents did — not just logs. AI Identity provides cryptographic proof via HMAC-SHA256 hash-chained audit entries that can be independently verified. Currently, there's no governance middleware in LangChain's partner ecosystem for this.

Proposed Solution

Reference PR #36590 as the ready implementation

extent analysis

TL;DR

The proposed solution is to integrate the langchain-ai-identity package into LangChain to provide agent governance and forensic-grade audit trails.

Guidance

  • Review the proposed implementation in PR #36590 to understand the changes required for integrating langchain-ai-identity into LangChain.
  • Verify that the langchain-ai-identity package meets the requirements for regulated industries, such as finance, healthcare, and legal, by reviewing the documentation and testing the package.
  • Evaluate the benefits of using langchain-ai-identity over other potential solutions, considering factors such as security, scalability, and maintainability.
  • Reopen PR #36590 and address any outstanding issues or concerns to move the implementation forward.

Example

No code snippet is provided as the issue is focused on a feature request and package integration.

Notes

The implementation of langchain-ai-identity is already available in PR #36590, but it was auto-closed due to a missing issue link. The package has been published on PyPI and documentation is available, which can be reviewed to understand its functionality and potential benefits.

Recommendation

Apply the workaround by reopening PR #36590 and addressing any outstanding issues to integrate the langchain-ai-identity package into LangChain, as it provides a ready implementation for agent governance and forensic-grade audit trails.
