Frequently Asked Questions about L4-deep-research

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

What is encyclopedic investment research and when do I need multi-framework validation?▼

Encyclopedic investment research applies Turn Every Page deep dives across 8+ frameworks for high-stakes holdings. You need it when allocating over 5% portfolio weight, entering new markets, or resolving severe multi-framework signal divergences.

How do I perform a full due diligence deep dive on a complex stock?▼

Perform a full due diligence deep dive by triggering the L4 analysis with commands like '@L4 [Company]' or 'Turn Every Page [Company]', executing multi-framework cross-validation, value chain mapping, and historical analogue comparisons.

Does L4 deep research require real-time market data feeds?▼

Yes, L4 deep research strictly requires real-time data feeds from yfinance and akshare. It enforces a zero-memory rule for numbers, demanding multi-source cross-validation where every key data point is double-checked against annual reports.

What is the difference between L3 and L4 investment analysis depth?▼

L3 analysis determines if a stock is worth watching, whereas L4 deep research ensures no blind spots remain. L3 requires 3 years of historical data, while L4 mandates 5 years and full encyclopedic coverage across 9 dimensions.

When should I avoid using encyclopedic deep research for stock valuation?▼

Avoid encyclopedic deep research for quick queries, routine analysis, or simple valuation updates. These lightweight tasks are better suited for L1, L2, L3, or dedicated valuation modules to save processing time.

Can I get multiple separate reports for different business segments from a deep dive?▼

No, a deep dive enforces a single deliverable policy. It outputs exactly one fully documented Markdown file containing all multi-framework analyses, historical precedents, and cross-checks, prohibiting any fragmented or interim reports.
