What people warn about
Each mark is one comment
Unclear examples and guidelines
“I don't understand the code in the examples after simply reading it.”
Comment from 14 Jul 2026 in “Show HN: Jacquard, a programming language for AI-written, human-reviewed code” “This system does not demonstrate this. It needs clear guidelines”
Comment from 14 Jul 2026 in “Show HN: Jacquard, a programming language for AI-written, human-reviewed code” Claims not fully implemented
“This system does not demonstrate this. It needs clear guidelines”
Comment from 14 Jul 2026 in “Show HN: Jacquard, a programming language for AI-written, human-reviewed code” “it doesn't look like it properly implemented those”
Comment from 14 Jul 2026 in “Show HN: Jacquard, a programming language for AI-written, human-reviewed code” Better suited to OS or libraries
“This feels like more of an OS problem (or library problem) than a language problem.”
