The gap it fixes

A real Liskov Substitution violation: a caller written assuming one implementation's behavior ("PayPalGateway never throws this") silently breaks when dependency injection hands it a different real implementation at runtime. No PMD/SonarQube/CodeQL rule found with this exact angle (PMD's MissingOverride is about a missing @Override annotation, a different concern); no dedicated Marketplace plugin found.

Refactor Simulator

Refactoring Tools

Preview every refactoring before committing it. Simulates a rename in an isolated, in-memory sandbox (using IntelliJ's own PSI, Find Usages, and refactoring processors, never a custom engine) and shows a full impact report, deterministic validation, and a native side-by-side diff before anything touches a real file.

A cognitive-complexity gutter icon for Java and Kotlin methods/functions: a colored badge with the real number, computed with SonarSource's documented Cognitive Complexity algorithm, never blocking the UI thread.

Shows errors and warnings inline, at the end of the line that has them, instead of only as a gutter icon or a squiggly underline you have to hover to read. One hint per line (most severe diagnostic wins) so it never turns into unreadable clutter.

Feature Flag Reference Companion

Code Quality / Feature Flags

Gutter icon next to every recognized feature-flag-check call's key literal in Java/Kotlin code (isEnabled("checkout_v2"), variation("checkout_v2", false), and similar), showing how many times that exact key is referenced anywhere else in the open project: helps find orphaned flags (dead code left behind after a rollout completed) without connecting to any provider. 100
