Make Claude Code 10x More Powerful (Only Plugins You Need)
The code intelligence plugin for Claude Code, which activates a built-in language server, is the only feature in the cost table that reduces file reads and context usage rather than charging per turn. It has been sitting in the binary since December 2025, switched off by default, and requires installing a separate language server binary (e.g., Pyrite, rust-analyzer, gopls) before it works. The real upgrade is not the plugin itself but the fact that the language server gives Claude diagnostics and precise navigation, fixing errors in the same turn and avoiding the context bloat of grep-based search. The most practical install set is the language server plugin for your language, Claude Code Setup, Context 7, Hookify, and one security reviewer—anything beyond that risks hoarding untested community plugins.
