SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Decision-making in investing is prone to bias and memory decay. This Skill enforces immediate documentation of key decisions, including explicit assumptions and invalidation signals, creating a verifiable trail for learning and accountability.

Core Features & Use Cases

  • Real-time decision logging: capture target, action, price, and position with up to three core arguments that can be verified later.
  • Explicit hypotheses and invalidation signals: require testable conditions to invalidate decisions and trigger reviews.
  • Reflective learning: automatically branch lessons into tasks/lessons.md for ongoing improvement.

Quick Start

Record a decision the moment it occurs, including the target, action, price, and any invalidation signals.

FAQPage Schema
How do I create an investment decision log to track my reasoning and prevent bias?

An investment decision log captures the target, action, price, position, core arguments, and testable hypotheses at the moment a decision is made. This creates a verifiable trail for learning and accountability by preventing memory decay and bias.

What is a post-mortem reflection in investing and how does it improve future decisions?

A post-mortem reflection analyzes past investment decisions against their original hypotheses and invalidation signals. It automatically extracts lessons into a dedicated file to enforce structured learning and improve ongoing investment workflows.

How do I record invalidation signals and testable hypotheses for an investment position?

You record invalidation signals by defining explicit testable conditions that would invalidate your investment decision. Logging these conditions at the moment of action triggers mandatory reviews when those signals occur.

What is the best way to document investment decisions for post-mortem analysis?

The best way to document investment decisions for post-mortem analysis is using structured templates with mandatory fields. This enforces immediate documentation of the target, action, price, position, and up to three core arguments for later verification.

Do I need specific file naming conventions for investment decision logs and reflections?

Yes, this approach enforces a standardized file naming convention alongside versioned templates for decision logs and reflections. This ensures your investment decision logs are consistently organized and easily retrievable for post-mortem analysis.

Can I automatically extract lessons from my investment decision logs into a tasks file?

Yes, you can automatically branch lessons from your decision logs and post-mortem reflections into a tasks and lessons file. This reflective learning mechanism allows for ongoing improvement of your investment workflows.
