⏱️ Estimated effort to review: 4 🔵🔵🔵🔵⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Async Implementation The recover_shards function uses await for API calls but the main function itself isn't properly defined as async, which could cause issues when called from non-async contexts. async def recover_shards( address: str, cid: str, auth_token: AuthToken, num_of_shards: int = 3, dynamic_data: Optional[Dict[str, Any]] = None, ) -> RecoverShards: Import Path The import statement uses an absolute path 'src.lighthouseweb3.functions.config' which may cause issues in different environments or when the package is installed. from src.lighthouseweb3.functions.config import Config Missing Docstring The recoverShards method in the Kavach class lacks a docstring explaining its purpose, parameters, and return values, unlike other methods in the class. def recoverShards(address: str, cid: str, auth_token: AuthToken, num_of_shards: int = 3, dynamic_data: Optional[Dict[str, Any]] = None): try: return recoverShards.recover_shards(address, cid, auth_token, num_of_shards, dynamic_data) except Exception as e: raise e

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Fix import path The import statement uses an absolute import path starting with 'src', which will cause import errors when the package is installed. Replace it with a relative import to ensure the code works correctly in all environments. src/lighthouseweb3/functions/kavach/util.py [6] -from src.lighthouseweb3.functions.config import Config +from ...config import Config Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies that using an absolute import path starting with src will cause ModuleNotFoundError when the package is installed, and proposes a valid relative import fix.
