SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When facing technical decisions with multiple viable approaches, it is hard to present trade-offs clearly and commit to a defensible recommendation. This Skill structures that analysis into a consistent 1-3-1 format so stakeholders can quickly understand the problem, compare options, and act on a concrete plan. ## Core Features & Use Cases - Structured Decision Format: Produces one problem statement, exactly three options (A, B, C) with pros and cons, and one direct recommendation. - Actionable Follow-Through: Includes a Definition of Done and an Implementation Plan with concrete steps, commands, and tools for the recommended option. - Adaptive Revision: Updates the recommendation, success criteria, and plan if the user selects a different option. - Use Case: A developer asks for a 1-3-1 on adding retry logic to an API client. The Skill outputs a comparison of a shared backoff utility, a retry library, and a queue-based approach, then recommends one with verifiable success criteria and an implementation plan. ## Quick Start Ask the agent to give you a 1-3-1 for choosing between approaches to your technical decision, such as selecting a migration strategy or architecture pattern.

FAQPage Schema
How do I structure a technical proposal with multiple options?▼

Use the 1-3-1 format: state one problem sentence, present exactly three options with pros and cons each, then give one recommendation with a definition of done and implementation plan. This keeps proposals concise and forwardable to stakeholders.

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

The 1-3-1 framework is a structured communication format with one problem statement, three distinct options with trade-offs, and one concrete recommendation. It forces clear problem framing and direct professional judgment instead of hedging.

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

Use it when a task has multiple viable approaches with meaningful trade-offs, such as architecture or tooling decisions. Do not use it for simple questions with one obvious answer, debugging sessions, or when the approach is already decided.

How many options should a technical trade-off analysis include?▼

This framework requires exactly three options labeled A, B, and C. The options must represent genuinely different strategies with distinct pros and cons, not minor variations of the same approach.

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

The format is unsuitable for simple questions, open-ended debugging, or cases where the decision is already made. It also requires enough context to define three genuinely distinct options and verifiable success criteria.
