SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Check whether code changes silently broke API contracts, behavior, schemas, or compatibility expectations. Use when reviewing endpoint changes, SDK updates, or public interface diffs.

Core Features & Use Cases

Compare diffs, configs, and interfaces to identify regression surfaces across endpoints, SDKs, and public contracts.
Prioritize high-impact gaps, regressions, or improvement opportunities with supporting repo evidence.
Propose minimal, verifiable fixes and validation steps to prevent recurrence.

Quick Start

Run the API regression guard against your change set to surface compatibility gaps and suggested fixes.

Frequently Asked Questions about api-regression-guard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I catch API regressions before they break clients?▼

Identify API regressions by comparing diffs, configs, and public interface changes across repositories to surface schema breaks, validate contracts, and prioritize high-impact compatibility gaps with supporting repo evidence.

How do I validate SDK updates and public interface diffs across repositories?▼

Validate SDK updates by comparing public interface diffs across repositories and services to identify regression surfaces, ensuring contract compatibility and behavioral consistency for clients consuming your endpoints.

What is the best way to review endpoint changes for silent contract breaks?▼

Review endpoint changes by applying a regression guard to compare diffs against existing API contracts, surfacing silent schema or behavioral breaks and proposing minimal, verifiable fixes to prevent recurrence.

Can I prioritize high-impact API compatibility gaps using code review?▼

Prioritize high-impact API compatibility gaps during code review by evaluating endpoint diffs and SDK changes, using supporting repo evidence to rank regression severity and propose targeted remediation steps.

When do I need to run an API contract validation against my code changes?▼

Run API contract validation when code changes modify endpoints, SDKs, or public interfaces, ensuring that diffs do not silently break compatibility expectations or alter schemas that clients depend on.
