SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The one-three-one-rule skill helps you make a clear, defensible choice when multiple technical or strategic options all seem viable, reducing confusion and debate overhead.

Core Features & Use Cases

  • Structured decision framing: Produces a one-sentence problem statement that stays focused on the decision to be made.
  • Exactly three distinct options: Generates three labeled approaches (A, B, C) with pros and cons to surface trade-offs.
  • Single actionable recommendation: Selects one option and explains the rationale in a direct, non-hedging way.
  • Execution-ready output: Includes a Definition of Done and an implementation plan aligned to the recommended path.
  • Use cases: Architecture decisions, tool selection, refactoring strategies, and migration paths where stakeholders need a concise proposal.

Quick Start

Ask for a 1-3-1 decision by saying: "Give me a 1-3-1 for choosing between these options for my system design: [brief context and constraints]."

FAQPage Schema
How do I structure technical proposals to present architecture trade-offs clearly?▼

Structure technical proposals by defining exactly one problem sentence, presenting three labeled options with pros and cons, and selecting a single recommendation with reasoning. This format surfaces architecture trade-offs clearly for stakeholder review.

What is the best way to decide between multiple viable refactoring strategies?▼

The best way to decide between refactoring strategies is to compare exactly three distinct approaches. Evaluating pros and cons for each option ensures a defensible choice while reducing debate overhead and confusion among stakeholders.

How do I create a decision-making framework for tool selection that includes an implementation plan?▼

Create a decision-making framework for tool selection by comparing three options, choosing one recommendation, and aligning it with a definition of done. This produces an execution-ready implementation plan tailored to the selected tool.

Can I use the one-three-one rule for migration paths where approaches must be compared rather than iterated?▼

Yes, the one-three-one rule applies directly to migration paths where distinct approaches must be compared rather than iterated. It converts ambiguous technical trade-off decisions into a single, actionable, stakeholder-ready recommendation.

When do I need a structured decision framing format for technical trade-off decisions?▼

You need structured decision framing for technical trade-off decisions when multiple viable options cause confusion. It produces a focused problem statement and a non-hedging recommendation to reduce debate overhead during architecture or tool selection.

Does this decision-making approach force a single recommendation even if options are close?▼

Yes, this decision-making approach forces a single actionable recommendation. It selects one option from the three presented and explains the rationale directly without hedging, ensuring a clear path forward for stakeholders.
