arXiv:2606.06337v1 Announce Type: new Abstract: Large language model (LLM) deployments for long-horizon tasks face a fundamental constraint: context windows are finite while productive work sessions are not. When history exceeds the Maximum Effective Context Window (MECW), critical structured information - architectural decisions, task transitions, file histories - is silently discarded. Existing mitigations treat history as flat text, destroying the relational structure that makes sessions resumable. We present TokenMizer, an open-source proxy system that models LLM session history as a typed
The proliferation of LLMs in complex, long-duration tasks, coupled with the inherent limitations of context windows, makes effective session management a critical bottleneck for further adoption and utility.
Improving LLM context management directly enhances the capability, reliability, and usability of AI systems for sustained productive work, unlocking new applications and improving user experience.
Current LLM interaction paradigms, which treat history as flat text, will evolve to incorporate structured memory, allowing for more intelligent and resumable sessions.

- · AI-powered software companies
- · Knowledge workers using LLMs
- · Inefficient AI context management solutions
- · Users limited by short context windows
More robust and less error-prone LLM applications for complex, multi-step tasks will emerge.
The economic value of LLMs in enterprise settings will increase as they become more capable of handling long-horizon projects.
This could accelerate the development of more sophisticated AI agents that maintain long-term memory and understanding across diverse tasks.
