Walkthrough

This update optimizes the HostWorkspace class by implementing lazy initialization for the SSH client. A boolean flag and a private method are introduced to manage the setup state, ensuring the SSH client is only initialized when necessary, thereby enhancing resource efficiency.

Changes

File(s)	Summary
python/composio/tools/env/host/workspace.py	Introduced lazy initialization for the SSH client with a boolean flag _is_ssh_client_set_up and a private method _setup_ssh_client. This change optimizes resource usage by setting up the SSH client only when needed.

Code Review Summary

The changes implement lazy initialization for the SSH client, which is a good improvement to the codebase. Here's my assessment:

Positive Aspects ✅

• Good separation of concerns by extracting SSH client setup into a dedicated method
• Proper implementation of lazy initialization pattern
• Maintains existing error handling and fallback mechanisms
• Clean and focused changes

Suggestions for Improvement 🔧

• Add proper type annotations and documentation for new class attributes
• Move _is_ssh_client_set_up initialization to __init__
• Add docstrings for the new _setup_ssh_client method

Testing Recommendations 🧪

• Add unit tests to verify lazy initialization behavior
• Test both successful SSH setup and fallback scenarios
• Verify SSH client is only initialized when needed

Overall, this is a good improvement that makes the code more efficient. With the suggested minor improvements in documentation and initialization, this PR is ready to be merged.
