SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When a technical task has multiple viable approaches, unstructured answers bury the decision. This Skill produces a consistent 1-3-1 decision brief so stakeholders get a clear problem statement, comparable options, and a direct recommendation they can act on or forward. ## Core Features & Use Cases - Structured Decision Format: Frames one problem sentence, exactly three options (A, B, C) with pros and cons, and a single recommendation with reasoning. - Actionable Follow-Through: Adds a Definition of Done and an Implementation Plan with concrete steps, commands, and tools for the recommended option. - Adaptive Revision: If the user picks a different option, the recommendation, success criteria, and plan update to match. - Use Case: A developer asks for options on adding retry logic to an API client. The Skill returns three strategies (shared backoff utility, retry library, queue-based retry), recommends one based on call volume, and lists verifiable success criteria plus an implementation plan. ## Quick Start Ask the agent to give you a 1-3-1 for your technical decision, such as choosing an architecture, tool, or migration strategy.

FAQPage Schema
How do I get a structured comparison of technical options?▼

Ask for a 1-3-1 brief on your decision. The response frames the problem in one sentence, presents three distinct options with pros and cons, recommends one with reasoning, and includes a Definition of Done and Implementation Plan.

What is the 1-3-1 decision-making format?▼

The 1-3-1 format is a decision brief structure: one problem statement, three viable options with trade-offs, and one recommendation. It adds success criteria and an implementation plan so the recommended path is immediately actionable.

When should I use a 1-3-1 brief instead of a direct answer?▼

Use it when a task has multiple viable approaches with meaningful trade-offs, or when you need a proposal to forward to a team. Skip it for simple questions with one obvious answer, debugging sessions, or decisions already made.

Can the recommendation change if I pick a different option?▼

Yes. If you select a different option than the one recommended, the Recommendation, Definition of Done, and Implementation Plan sections are revised to align with your chosen approach.

What are the limitations of the 1-3-1 format?▼

The format requires exactly three genuinely distinct options, so it does not fit problems with only one or two real approaches. It is also unsuitable for open-ended debugging or exploratory tasks without a clear decision point.
