How do I install it?
Run `npx skills add himself65/finance-skills --skill yc-reader --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From himself65/finance-skills, a repository with 3,115 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
