TokenEconomizer: Microsoft Research and UC Berkeley tool for saving tokens in coding agents
TokenEconomizer is a Microsoft Research and UC Berkeley tool published on GitHub that integrates with Claude Code, Codex, Copilot CLI, and Pi, helping AI coding agents save tokens by learning from repository session history.
Microsoft Research and the University of California, Berkeley (UC Berkeley) introduced TokenEconomizer, a GitHub-published tool that integrates with Claude Code, Codex, Copilot CLI, and Pi.
TokenEconomizer learns from the history of previous sessions in a repository:
- remembers commands that work successfully in a given project;
- excludes unused tools;
- helps the AI agent escape loops of repeated errors.
As a result, the agent can spend fewer tokens on retries and unnecessary actions, while developers get more stable behavior when working with a codebase.

Why it matters
AnalysisIt shows how session-aware memory can reduce cost and latency for AI coding agents, especially in large repositories where repeated errors quickly consume tokens.
