Background & analysis
According to a DEV Community post dated October 31, 2026, Hallmark is an MIT-licensed skill aimed at Claude Code, Codex, Cursor and OpenCode, and version 2.0.0 merged on October 22. The author describes it as more than a long prompt: a prompt plus a set of rule scripts. The post says it reached the top of GitHub's trending list on Tuesday with 2,830 stars that day; when the author checked, the GitHub API reported 39,048 stars. Running the rules against the author's own product homepage flagged all six top-level headings for the same tells: a small pill or a line of capitals above each heading and an italic serif word at the end, with two pill phrases matching word for word phrases in the lint's source code. From this the author draws the claim that you cannot write a test for taste, only for the tells. The material covers no maintainer response, no follow-up release and no subsequent fixes.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
