Where's the Fault (WTF)?

When an alert pops up in your monitoring channel, figuring out its source can be a hassle. Maybe someone is new to the team? Maybe you just forgot the correct procedure to follow during an incident? Where’s the Fault (WTF)? is a terminal-based assistant designed to help dev teams trace the origin of an issue through an interactive, structured workflow.

Built with Svelte, it provides a streamlined way to navigate through possible causes and solutions.

How It Works

At its core, WTF is an interactive flowchart presented in a terminal interface. It guides users through a series of prompts, allowing them to answer questions, get additional information, or jump directly to relevant documentation.

Configuring the Workflow

The workflow is defined in src/lib/prompts.ts as an array called promptCollection. Each prompt represents a step in the troubleshooting process and can be one of the following:

Questions → Directs the user to the next step based on their answer.
Information messages → Provides additional context or explanations.
Links to documentation → Guides the user to external resources for deeper insights.

All prompts are type-assisted, ensuring consistency and maintainability.
