When writing documentation in code (comments, docstrings, example snippets), ensure every instruction and external link precisely matches the actual package extras and the implemented service/provider. Apply this checklist: - Installation examples: use the correct `pip` syntax for editable installs and extras, and confirm the package name. - Prefer patterns like: - `pip install -e ".[openai]"` - `pip install "db-gpt[openai]"` - External API links in comments/docstrings: only keep references that match the real backend/provider. If the code is for Google Gemini, don’t keep ZhiPu-specific API docs—update the link/title or remove it. Example (corrected install snippet): ```bash # Install extra support pip install -e ".[openai]" # or pip install "db-gpt[openai]" ``` If you’re unsure which doc/link is correct, verify against the project’s packaging metadata (extras) and the exact provider SDK you’re calling.
