 ## Screenshot Verification
 
 The screenshot verification workflow allows you to capture screenshots of web pages and verify their appearance using LLMs. The following tools are available:
 
 1. Screenshot Capture:
 ```bash
-venv/bin/python tools/screenshot_utils.py URL [--output OUTPUT] [--width WIDTH] [--height HEIGHT]
+venv/bin/python3 tools/screenshot_utils.py URL [--output OUTPUT] [--width WIDTH] [--height HEIGHT]

 ```bash
-venv/bin/python tools/llm_api.py --prompt "Your verification question" --provider {openai|anthropic} --image path/to/screenshot.png

 ## User Specified Lessons
 
-- You have a python venv in ./venv. Use it.
-- Include info useful for debugging in the program output.
-- Read the file before you try to edit it.
+- You have a python venv in ./venv. Always use (activate) it when doing python development. First, to check whether 'uv' is available, use `which uv`. If that's the case, first activate the venv, and then use `uv pip install` to install packages. Otherwise, fall back to `pip`.
 - Due to Cursor's limit, when you use `git` and `gh` and need to submit a multiline commit message, first write the message in a file, and then use `git commit -F <filename>` or similar command to commit. And then remove the file. Include "[Cursor] " in the commit message and PR title.
 
 ## Cursor learned
 
 - For search results, ensure proper handling of different character encodings (UTF-8) for international queries
-- Add debug information to stderr while keeping the main output clean in stdout for better pipeline integration
 - When using seaborn styles in matplotlib, use 'seaborn-v0_8' instead of 'seaborn' as the style name due to recent seaborn version changes
 - Use 'gpt-4o' as the model name for OpenAI's GPT-4 with vision capabilities
 - When searching for recent news, use the current year (2025) instead of previous years, or simply use the "recent" keyword to get the latest information
