13 legendary investors. One command. Zero setup.

Market Sages summons a council of the world's greatest investors to analyze any stock — Warren Buffett, Charlie Munger, Benjamin Graham, Michael Burry, Nassim Taleb, and 8 more. No API keys. No Python environment. No financial data subscription. Just a ticker symbol.

You type:

/sages NVDA

You get a full council deliberation:

╔══════════════════════════════════╗
║  🧠 Warren Buffett               ║
║  Signal: NEUTRAL                 ║
║  Confidence: 55%                 ║
║  Reasoning: Exceptional moat     ║
║  (gaming ecosystem), but current ║
║  P/E leaves no margin of safety. ║
╚══════════════════════════════════╝

╔══════════════════════════════════╗
║  🧠 Michael Burry                ║
║  Signal: BEARISH                 ║
║  Confidence: 72%                 ║
║  Reasoning: FCF yield ~1.8%,     ║
║  EV/EBIT ~80x — no deep value    ║
║  here, this is momentum not math.║
╚══════════════════════════════════╝

... (11 more sages)

╔══════════════════════════════════════════════╗
║  🏦 PORTFOLIO MANAGER — FINAL VERDICT        ║
║  Action: WATCH                               ║
║  Conviction: MEDIUM                          ║
║  Entry Strategy: Wait for 20-25% pullback    ║

Copy the contents of skill.md as your system prompt in any LLM interface — ChatGPT, Claude.ai, Gemini, Perplexity, or any custom app. Then start chatting.

1. Paste your own data for sharper analysis

/sages AAPL

Revenue: $391B (+2% YoY)
Net Income: $94B
FCF: $107B
P/E: 28x, EV/EBITDA: 22x
Debt: $104B, Cash: $65B
Recent news: Vision Pro sales disappointing...

The sages will use your data instead of potentially stale training knowledge.

2. Ask follow-up questions

What would make Buffett upgrade to bullish on AAPL?
What's Taleb's worst-case scenario for NVDA?
How does Burry's AAPL thesis compare to his typical deep-value plays?

3. Sector sweeps

/sages compare AAPL MSFT GOOG META AMZN  (Big Tech council)
/sages compare JPM BAC GS                (Banking council)

4. Portfolio review

Review my portfolio: 40% AAPL, 30% NVDA, 20% TSLA, 10% BTC
Which sages would be most concerned?

Q: /sages command not found after installation

# Re-copy and verify the file is in the right place
cp skill.md ~/.claude/skills/market-sages.md
ls ~/.claude/skills/market-sages.md

Then restart Claude Code and try again.

Q: The sages are using outdated data Paste current financial data directly in your message — the sages will prioritize it over training knowledge:

/sages NVDA
Revenue $60.9B, P/E 55x, Gross Margin 74.6%...

Q: Can I use only a subset of sages? Yes — use @ to name them:

/sages AAPL @buffett @graham @burry

Q: The analysis is in the wrong language The skill auto-detects your input language. Write your prompt in the language you want the response in.

Q: How do I run the tests?

# Structure validation (no API key needed)
uv run tests/validate_structure.py --verbose

# Prompt evaluation (requires ANTHROPIC_API_KEY)
export ANTHROPIC_API_KEY=sk-...
uv run tests/run_evals.py
