Hey @Mamurbakhromov — cool to see crypto/macro/equities coverage, this fills a genuine gap!

A couple things need fixing before we can merge:

1. Emoji format — the emoji values in your frontmatter are hex codepoints (e.g., emoji: f4c9) instead of actual emoji characters. They need to be the rendered glyphs (e.g., emoji: 📊). This will break our conversion tooling as-is.

2. Vibe diversity — "disciplined" appears in nearly every agent's vibe. Each agent should have a distinct personality. Take a pass and give each one a unique voice — what makes the Crypto Derivatives Risk Analyst feel different from the Macro Policy Regime Analyst?

Content quality is solid otherwise. Fix those two things and we're good to go!
