SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides an impact-analysis-first workflow for modifying existing features, including backward-compatibility assessment and breaking-change detection. It auto-executes when the user clearly intends to modify how a feature behaves (not for bug fixes or refactoring).

Core Features & Use Cases

  • Impact Analysis: Evaluates how a modification affects dependent components and downstream behavior.
  • Backward Compatibility & Breaking Changes: Detects potential compatibility issues and proposes migration strategies.
  • Automated Execution Flow: Orchestrates the modify process, from extracting the modification intent to implementing changes and validating results.

Quick Start

Example:

  • User: "Change authentication from session to JWT"
  • Then invoke the modify workflow to apply the change, generate a migration plan, and verify outcomes.

FAQPage Schema
How do I modify a feature's behavior while detecting breaking changes?▼

Impact-driven feature modification automatically detects breaking changes by analyzing how behavior shifts affect dependent components. The workflow evaluates backward compatibility, identifies migration requirements, and generates a change specification before implementation.

What's the best way to change API behavior without breaking existing clients?▼

Assess impact first: evaluate dependent systems, propose migration strategies, and validate backward compatibility. This Skill orchestrates that workflow—from extracting modification intent through implementing changes and running regression validation.

How do I plan a feature change like switching authentication or pagination logic?▼

Define the modification (e.g., session to JWT, offset to cursor pagination), invoke impact analysis to map affected components, generate a migration plan, update specifications, and execute implementation with automated regression testing.

Can I automate detection of what breaks when I modify an existing feature?▼

Yes. Automated impact analysis identifies compatibility issues, breaking changes, and downstream effects across dependent components. The workflow generates task lists for migration and validates outcomes through regression testing.

When should I use impact analysis before modifying feature behavior?▼

Use it when a feature must change how it behaves—authentication, search, response formats, or pagination logic. It's designed for intentional behavior shifts, not bug fixes or refactoring, and includes breaking-change detection and migration planning.
