SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents wasted effort and downstream bugs by forcing a structured pre‑implementation analysis of any change that touches existing behavior, shared components, or multiple system parts.

Core Features & Use Cases

  • Impact Loading: Maps dependencies, contracts, and hidden consumers of the component to be changed.
  • Blast Radius Estimation: Categorizes risk levels (small, medium, large) and recommends appropriate safety measures.
  • Mental Simulation: Walks through happy, failure, and edge‑case paths to surface hidden issues before code is written.
  • Use Cases: New feature development, bug fixes, refactors, or any task that modifies critical code paths.

Quick Start

Ask the AI to run the “analyze‑before‑coding” skill to generate a pre‑implementation analysis summary before you begin any change.

FAQPage Schema
How do I estimate the blast radius before modifying shared components?▼

To estimate blast radius, map dependencies and hidden consumers of the target component, categorize risk levels as small, medium, or large, and recommend appropriate safety measures before implementation.

What is the best way to assess code change impact for a new feature?▼

Assessing code change impact requires loading dependency mappings, contracts, and hidden consumers, then walking through happy, failure, and edge-case paths to surface hidden issues before writing code.

How do I run a pre-implementation analysis when system architecture context is missing?▼

When architecture context, dependency graphs, or rule sets are unavailable, pre-implementation analysis falls back to manual simulation to identify potential impact and risks for critical code paths.

When should I perform an impact analysis before refactoring existing behavior?▼

Perform impact analysis before any implementation task that modifies existing behavior, touches shared components, or spans multiple system parts, including new features, bug fixes, and refactors.

Why does mental simulation help prevent downstream bugs during software engineering?▼

Mental simulation prevents downstream bugs by walking through failure and edge-case paths during the pre-implementation phase, forcing a structured assessment that surfaces hidden issues before code is written.
