What is serenity-reply?

This is an AI agent skill that lets you consult an artificial reconstruction of Serenity, a market analyst with over 360,000 followers who specializes in AI and semiconductor supply chains. The project distilled his publicly visible thinking from over 1,700 posts, interviews, and third-party commentary into a set of mental models and decision rules that an AI agent can apply when you ask stock-related questions. The analyst's core approach involves finding small, often overlooked companies that are chokepoints in the AI supply chain. These are suppliers that institutions and retail investors alike tend to miss, but whose absence would halt production across an entire industry segment. His past analyses include calls on several small companies that later saw large price moves and attracted coverage from major financial press. The skill captures five mental models, eight decision rules, and a detailed record of his writing and response style. When activated, you can ask it to evaluate a stock from his perspective, and it will reason using his framework rather than generic financial analysis. It works in two modes: first-person where the AI speaks as the analyst, or an advisor mode where it describes how he would likely reason about the question in the third person. The skill is built on the Agent Skills protocol and can be installed in compatible AI agent runtimes including Claude Code. Installation takes a single command or a manual file copy. The underlying research files are included in the repository with source citations so you can see how each conclusion was reached. The README is unusually forthcoming about limitations. It notes that the analyst's credentials have not been independently verified, that no public record of acknowledged mistakes was found in the research, that survivorship bias likely inflates the apparent accuracy of his calls, and that his valuation discipline has a known weak point around high-revenue-multiple positions. The skill intentionally reproduces these weaknesses rather than correcting them. All outputs carry a disclaimer that nothing constitutes investment advice.
