PR Reviewer Guide 🔍

⏱️ 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 in main.py might not include proper spacing between concatenated strings, which could lead to a malformed output. Consider adding spaces around + operators.
	Code Consistency: The use of single quotes for 'COMPOSIO_API_KEY' and double quotes for other strings in main.py should be made consistent to follow best practices.

PR Code Suggestions ✨

Category	Suggestion	Score
Best practice	Use f-strings for better readability and to avoid potential issues with string concatenation ___ **The string concatenation in the agent.chat call can be improved for better readability and to avoid potential issues with missing spaces. Using an f-string would make the code cleaner and more readable.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [39-40]](https://github.com/ComposioHQ/composio/pull/194/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: The suggestion correctly identifies a readability and potential error issue with string concatenation and proposes a cleaner solution using f-strings, which is a best practice in Python.	8
Possible issue	Add error handling for missing COMPOSIO_API_KEY environment variable ___ **The ComposioToolSet initialization should handle the case where the environment variable COMPOSIO_API_KEY is not set, to avoid potential runtime errors.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [11]](https://github.com/ComposioHQ/composio/pull/194/files#diff-0a4f1947c27e6fa99c9965d43d845b6a8dee01782ba14f51e3c24ac45ff9e021R11-R11) ```diff -toolset = ComposioToolSet(api_key=os.environ['COMPOSIO_API_KEY']) +api_key = os.getenv('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]: 7 Why: Proper error handling for missing environment variables is crucial for avoiding runtime errors. The suggestion to check and raise an error if `COMPOSIO_API_KEY` is not set is valid and improves the robustness of the code.	7
	Add error handling for missing OPENAI_API_KEY environment variable ___ **The OpenAI initialization should handle the case where the environment variable OPENAI_API_KEY is not set, to avoid potential runtime errors.** [python/examples/sql_agent/sql_agent_plotter_llama_index/main.py [17]](https://github.com/ComposioHQ/composio/pull/194/files#diff-0a4f1947c27e6fa99c9965d43d845b6a8dee01782ba14f51e3c24ac45ff9e021R17-R17) ```diff -llm = OpenAI(model="gpt-4o") +openai_api_key = os.getenv('OPENAI_API_KEY') +if not openai_api_key: + raise EnvironmentError("OPENAI_API_KEY environment variable not set") +llm = OpenAI(model="gpt-4o", openai_api_key=openai_api_key) ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 7 Why: This suggestion is important for ensuring the application handles missing critical configuration properly. However, the existing code does not use `OPENAI_API_KEY`, which makes the suggestion slightly out of context but still a good practice for future-proofing.	7
Enhancement	Correct a typo in the documentation for better readability ___ **Fix the typo "queriesm" to "queries" for better readability and professionalism.** [python/examples/sql_agent/sql_agent_plotter_crewai/readme.md [3]](https://github.com/ComposioHQ/composio/pull/194/files#diff-e8bfd3023bb50ee93be91aa853ff2a5d139af9df20183df227de3cdc58dec9e0R3-R3) ```diff -This guide provides detailed steps to create a SQL agent that leverages CrewAI, 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 CrewAI, Composio, and ChatGPT to execute SQL queries, document them and plot graphs based on them. ``` - [ ] **Apply this suggestion** Suggestion importance[1-10]: 5 Why: Fixing typos in documentation is important for professionalism and clarity. This suggestion correctly identifies and fixes a typo, enhancing the readability of the document.	5
