⏱️ Estimated effort to review [1-5]	2
🧪 Relevant tests	No
🔒 Security concerns	No
⚡ Key issues to review	Possible Bug: The string concatenation in the agent.chat call uses a '+' operator without spaces around the concatenated strings. This might lead to a concatenated string without proper spacing, which could affect the output or processing. Consider adding spaces around the concatenated parts: python "Database description = " + human_description + " Task to perform: " + human_input

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Add error handling for missing environment variables ___ **Consider adding error handling when accessing environment variables to provide a clear message if the COMPOSIO_API_KEY is not set.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [11]](https://github.com/ComposioHQ/composio/pull/193/files#diff-0a4f1947c27e6fa99c9965d43d845b6a8dee01782ba14f51e3c24ac45ff9e021R11-R11) ```diff -toolset = ComposioToolSet(api_key=os.environ['COMPOSIO_API_KEY']) +api_key = os.environ.get('COMPOSIO_API_KEY') +if not api_key: + raise EnvironmentError("COMPOSIO_API_KEY environment variable not set") +toolset = ComposioToolSet(api_key=api_key) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 9 Why: Adding error handling for missing environment variables is crucial for debugging and user experience, preventing runtime errors and providing clear error messages. This suggestion significantly improves the robustness of the code.	9
Enhancement	Simplify string concatenation by using an f-string ___ **The string concatenation in the agent.chat call can be simplified and made more readable using an f-string.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [39-40]](https://github.com/ComposioHQ/composio/pull/193/files#diff-0a4f1947c27e6fa99c9965d43d845b6a8dee01782ba14f51e3c24ac45ff9e021R39-R40) ```diff response = agent.chat( - "Database description ="+ human_description +"Task to perform:" + human_input + f"Database description = {human_description} Task to perform: {human_input}" ) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 8 Why: Using f-strings improves readability and maintainability of the code. The suggestion correctly identifies a less readable string concatenation and provides a cleaner alternative.	8
Best practice	Move the dotenv.load_dotenv() call to the top of the file after imports ___ **The dotenv.load_dotenv() call should be moved to the top of the file after the imports to ensure environment variables are loaded before they are accessed.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [9-11]](https://github.com/ComposioHQ/composio/pull/193/files#diff-0a4f1947c27e6fa99c9965d43d845b6a8dee01782ba14f51e3c24ac45ff9e021R9-R11) ```diff dotenv.load_dotenv() -... toolset = ComposioToolSet(api_key=os.environ['COMPOSIO_API_KEY']) ``` Suggestion importance[1-10]: 7 Why: Moving `dotenv.load_dotenv()` to the top ensures all environment variables are available when needed. This is a good practice, especially in a script that relies on environment variables early in its execution.	7
Maintainability	Fix a typo in the guide description ___ **Fix the typo "queriesm" to "queries" in the guide description.** [python/examples/sql_agent/sql_agent_plotter_llama_index/readme.md [3]](https://github.com/ComposioHQ/composio/pull/193/files#diff-358ceca7f7e9d219132e3f08c1b1b3145e1af322e277400667029cb2f9ff7d28R3-R3) ```diff -This guide provides detailed steps to create a SQL agent that leverages LlamaIndex, Composio, and ChatGPT to execute SQL queriesm, document them and plot graphs based on them. +This guide provides detailed steps to create a SQL agent that leverages LlamaIndex, Composio, and ChatGPT to execute SQL queries, document them and plot graphs based on them. ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 6 Why: Correcting typos improves the professionalism and readability of documentation. This is a minor text correction but enhances the quality of the document.	6
