Other notable agents' LOC: Codex (Rust) ~519K, Gemini (TS) ~445K, OpenCode (TS) ~254K, Pi (TS) ~113K LOC. Pi's modular structure makes it simple to see where most of code is. Respectively core, unified API, coding agent CLI, TUI have ~3K, ~35K, ~60K, ~15K LOC. Interestingly, the just uploaded claw-code's Rust version is currently at only 28K.

edit: Claude is actually (TS) 395K. So Gemini is more bloat. Codex is arguable since is written in lower-level language.
