Tech & Development Prompts Add meaningful comments that explain WHY — not narrate WHAT — in your language's documentation conventions. This AI code comment generator prompt writes meaningful comments — inline notes, function docstrings, and module headers — in the correct format for your language (JSDoc, Python docstrings, Javadoc, Godoc, rustdoc, TSDoc, YARD), focused on why the code exists rather than what it does. Paste into Claude, ChatGPT, or any AI chat, drop in your code, and get it back properly commented with a diff summary and quality notes. Most generated comments are worse than nothing because they narrate the obvious — "// increment i by 1." This prompt bans that class of comment by rule and adds only what future engineers will thank you for: business context, non-obvious decisions, trade-offs made, workarounds with ticket references, and performance-critical gotchas. If a comment would be better served by a rename or refactor, it flags it instead. Works with Claude, ChatGPT, or any AI chat model.
