ClawCodex
A production-oriented, token-efficient Python rebuild of Claude Code's reference TypeScript implementation, adding persistent multi-agent teams, a session supervisor and measured token-compression of command output.
ClawCodex is described as a production-oriented Python rebuild of Claude Code, ported from its TypeScript reference implementation and extended with a Python-native runtime, aiming for token-efficient operation at scale. Its multi-agent teams feature lets a session become a leader that creates named teammates who stay alive between assignments, message each other and the leader, and pull work from a shared, dependency-aware task board, while one session-scoped supervisor admits, tracks and can interrupt every subagent, foreground or background; background workers resume with their history under the same ID, and worktree isolation runs in a real Git checkout or fails before the model runs.
Its /eco token-compression feature applies deterministic filters to command output, failure-focused test summaries, stripped git/pip/npm ceremony output, log deduplication, and recoverable head-caps for long output, reducing Bash-output tokens by a measured 80 percent on one benchmark set of real command outputs, with anything trimmed still available on disk.
The project reports 80.9 percent on the verified 89-task Terminal-Bench 2.1 suite running headless on Claude Opus 5, reproducible from an open-source Harbor adapter.
