Karellen

Use this agent when you need deep code understanding across a large codebase, when tracing call chains or type hierarchies would require reading many files, when you need to find all references to a symbol, or when compiler diagnostics would help understand build errors. This agent registers the project with the appropriate LSP server and uses structured code intelligence (definitions, references, hover, call hierarchy, type hierarchy, diagnostics) to investigate code without reading entire files. Supports C, C++ (clangd), Java, and Kotlin (jdtls), Python (pyright), and Rust (rust-analyzer).

Investigate code using LSP tools. Register a project, then use definitions, references, call hierarchies, type hierarchies, hover, and diagnostics to understand code structure, trace bugs, and assess change impact.

Register a project for LSP code intelligence. Auto-detects language and build system, or accepts explicit configuration. Handles C/C++ (clangd), Java/Kotlin (jdtls), Python (pyright), Rust (rust-analyzer), and custom LSP servers.
