Log Format String Companion
FreeCode Quality / Logging
Flags a log message whose placeholder count doesn't match its argument count: an error that today only surfaces at runtime: a leftover placeholder stays literal in the log output, or an extra argument is silently dropped, or (worst case) SLF4J misinterprets the last argument as an exception when it isn't one. Deliberately narrow (not a full SAST scanner like Qodana): o
The gap it fixes
An original idea, not a port of an existing competitor — validated against this catalog's own idea-validation discipline before being built: (1) confirmed no plugin in this catalog does exactly this, and a search for "log format" only surfaces MyBatis output formatters — an unrelated tool, not a placeholder/argument mismatch inspector; (2) confirmed buildable in the ~10-day budget with techniques this catalog already has proven — LocalInspectionTool.checkFile doing a whole- document regex scan, the exact mechanism sql-concatenation-companion already proved in this catalog (reused directly,

All Code Quality pluginsPreview 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.
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
