Paste this into Claude Code to set it up:

I want to add the Greatest People agent to my Claude Code setup.

Create the file ~/.claude/agents/greatest-people.md with the agent definition. The frontmatter must start on line 1 (no blank line before ---).

The agent should:
- Conduct deep biographical research on history's most successful people
- Analyze early career decisions, biggest levers, daily habits, and mindset patterns
- Synthesize cross-person patterns and actionable takeaways
- Model: opus
- Tools: Read, Write, Edit, Bash, Grep, Glob, WebSearch, WebFetch
- Color: yellow

This agent works best with Perplexity MCP for deep web research and a local knowledge base for accumulating biographical notes across sessions.

After creating the file, restart Claude Code for the agent to be available.

01What It Does

Learn from the greatest, systematically

Most biographical content focuses on the highlight reel. This agent digs into the mechanics: what specific decisions did they make at age 20 that compounded for decades? What daily routines persisted across their entire career? What counterintuitive bets did they make that others avoided? The output is not a biography summary; it is a structured extraction of the levers that created extraordinary outcomes.

Individual Deep DivesRequest a profile on any historical figure and get a structured analysis covering their early life context, career inflection points, daily systems, and the compounding effects of their key decisions.

🔗

Cross-Person SynthesisAfter researching multiple people, ask the agent to find patterns. Which habits appear across 80% of exceptional achievers? Which strategies are domain specific versus universal?

📝

Actionable ExtractionEvery research session ends with concrete takeaways: principles you can apply, routines you can test, and mental models you can adopt. Theory grounded in historical evidence.

02Research Framework

Origin Context

Family background, economic conditions, education (or lack thereof), early influences, and the specific environment that shaped their worldview before they achieved anything.

Career Inflection Points

The 3 to 5 pivotal decisions that changed their trajectory. For each: what they chose, what the alternative was, what information they had at the time, and why that choice compounded.

Daily Systems and Habits

Morning routines, work schedules, reading habits, exercise patterns, and how they protected their most productive hours. Focus on what persisted for years, not one-off practices.

Mindset and Mental Models

How they thought about risk, failure, competition, and time horizons. The internal frameworks that guided their decision making under uncertainty.

Relationship Strategy

How they chose mentors, partners, and teams. Who they surrounded themselves with at each stage and how those relationships contributed to their outcomes.

Contrarian Bets

Decisions that went against conventional wisdom at the time. What others criticized that later proved prescient, and the reasoning behind those unconventional moves.

Compounding Effects

How early decisions created exponential returns over decades. The specific mechanisms (reputation, capital, knowledge, network) through which their advantages compounded.

03Output Format

	Output Type	Details
Individual Profile	Deep dive on one person	A structured markdown document covering all seven dimensions of the research framework. Typically 2,000 to 4,000 words with specific examples and sourced claims.
Pattern Analysis	Cross-person synthesis	Compares multiple researched individuals to find recurring themes. Highlights universal patterns versus domain specific strategies with confidence levels for each finding.
Actionable Summary	Personal application guide	Distills research into principles ranked by applicability. Each principle includes the evidence base (which people demonstrated it) and a concrete way to test it in your own life.

All profiles are saved to your local knowledge base as markdown files. Over time, you build a personal library of biographical research that the agent can reference for cross-person pattern analysis and deeper synthesis.
