docs: add langchain-integration-health tool documentation

[sadiqkhzn]

Summary

This PR adds documentation and package registration for the LangChain Integration Health Framework, a comprehensive testing and monitoring solution for LangChain integrations.

What this framework provides:

• Automated Integration Testing: Tests for bind_tools(), streaming, structured output, and async support
• Real-time Dashboard: Web-based monitoring of integration compatibility
• MLXPipeline Fix: Complete solution for missing bind_tools functionality
• CLI Tools: Command-line interface for testing and reporting
• CI/CD Integration: GitHub Actions workflows for automated monitoring

Key Features:

✅ Tests 50+ LangChain integrations automatically
✅ Identifies compatibility issues before runtime
✅ Provides visual compatibility matrix
✅ Includes performance benchmarking
✅ Exports results in JSON/CSV/Markdown formats

Package Information:

• PyPI: langchain-integration-health
• GitHub: sadiqkhzn/langchain-integration-health
• Installation: pip install langchain-integration-health

Changes Made:

1. Added comprehensive documentation notebook at docs/docs/integrations/tools/langchain_integration_health.ipynb
2. Registered package in libs/packages.yml

This framework addresses critical pain points in the LangChain ecosystem, particularly around integration compatibility and testing gaps.

Test plan:

• Package successfully installs via pip
• CLI commands work correctly
• Dashboard launches and displays compatibility matrix
• Documentation notebook runs without errors
• Examples demonstrate MLXPipeline fix functionality

CodSpeed WallTime Performance Report

Merging #32788 will improve performances by 18.87%

_{Comparing sadiqkhzn:master (12be049) with master (338d3d2)}

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

Hello, thanks for this. Looks really interesting! I don't think it has a place in the langchain docs at the moment— it is not a langchain component. I see it's been documented under tools but it is not a tool in the langchain sense.

I'd encourage you to check out the langchain-tests library if you haven't already:

• docs
• API ref

It captures supported chat model features (e.g., support for tool calling, structured outputs, image/PDF/audio inputs, etc). It is not designed runtime checks in the same way as this is, though this is something we've considered developing.

[sadiqkhzn]

You're right, this fits better in the ecosystem around LangChain rather than core docs. I hadn't seen langchain-tests before, but after checking it out, there's definitely overlap in what we're solving. I'm interested in your mention of considering runtime checks for langchain-tests, that's exactly what my framework focuses on.

Would there be interest in discussing how the runtime testing capabilities could complement langchain-tests instead of maintaining separate efforts? I'd much rather contribute to existing ecosystem tools than promote a standalone project.

Thanks for taking the time to review and for the guidance!
