# Serenity.skill > Researches tech and advanced-manufacturing investment themes by finding supply-chain bottlenecks, then ranks which companies to study first. Serenity.skill is a community Agent Skill by muxuuu that turns the supply-chain research approach seen in the public posts of investor Serenity (@aleabitoreddit) into a research workflow for your agent. It starts from a technology theme, maps the system and its hardest-to-expand inputs, investigates the companies involved, and returns a ranked list of what to research next, with evidence and risks. What you can do with it - Scan a theme, such as A-share AI semiconductors, robotics, CPO or power equipment, layer by layer, then get a short priority list of companies or fund directions - Challenge a claim, such as whether a company is really a core supplier, separating its product role, delivery status, customers and attributable revenue - Compare a few candidate companies on supply-chain position, strength of evidence, valuation pressure and risk - Learn the method one focused question at a time How it works - It asks what demand is putting pressure on the system, which layers are hard to expand or substitute, and what each company actually sells and has delivered. - Claims go back to dated original sources such as announcements, exchange filings, financial reports and earnings calls, and it returns fewer candidates when the evidence is thin. - It's built mainly for A-share themes and adapts to other markets you ask about. - It needs an agent with its own web search, browsing or filing access; it brings the method and reference material, not market data. How to install it - Clone the repo and copy the skill files into ~/.claude/skills/serenity-skill for Claude Code or ~/.agents/skills/serenity-skill for Codex, then start a new session.
