SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This skill solves the problem of unexamined assumptions and cognitive bias in complex, high-stakes decision-making by enforcing a visible, sequential reasoning process.

Core Features & Use Cases

Sequential Reasoning: Breaks complex problems into numbered, challengeable thought steps.
Assumption Surfacing: Explicitly identifies and tests assumptions before reaching a conclusion.
Use Case: Use this when evaluating a high-stakes market entry, resolving contradictory signals in a deal, or determining strategy under uncertainty to ensure every recommendation is backed by a transparent chain of logic.

Quick Start

Activate the deep-think skill by asking the agent to think through the strategic implications of the current deal.

FAQPage Schema

How do I structure reasoning for high-stakes decisions involving multiple variables?▼

To surface and test assumptions in complex reasoning, this skill explicitly identifies and challenges hidden assumptions during the sequential thinking process, ensuring recommendations are backed by a transparent chain of logic rather than cognitive bias.

How do I validate strategic reasoning against existing evidence in my workspace?▼

To validate strategic reasoning against existing evidence, this skill integrates with workspace context files and data stores, cross-referencing your sequential thought steps with available data to ensure logical consistency.

What is the best way to determine strategy under uncertainty and contradictory market signals?▼

The best way to determine strategy under uncertainty is to use a structured reasoning process that explores alternative paths and surfaces assumptions, generating maritime-framed course recommendations to navigate contradictory signals.

Can I use sequential reasoning for evaluating a high-stakes market entry?▼

Yes, you can use sequential reasoning for evaluating a high-stakes market entry by activating the skill to think through the strategic implications of the current deal, breaking the evaluation into visible, challengeable steps.
