Written by AI, Managed by AI: Semantic Space Control and Index Sickness Elimination Across 391 Consecutive Sessions

arXiv:2606.19121v1 Announce Type: cross Abstract: The prevailing engineering intuition for addressing conceptual drift in long-horizon LLM collaboration is to trade more formal constraints for more reliable outputs -- designing symbolic identifier systems, accumulating defensive rules in System Prompts, expanding context windows. Our engineering record shows that in long-horizon settings, this direction may produce effects contrary to design intent. Using action research methods in a real software project (Bang-v3) spanning approximately one month and 391 collaborative sessions, we document an

Why this matters
Why now

The paper addresses a critical challenge emerging as LLM applications move beyond prototypes into long-term, complex collaborative environments, where conceptual drift and maintenance become significant issues.

Why it’s important

This research provides empirical evidence and a potential solution for managing the inherent instability of long-horizon AI agent interactions, which is crucial for the deployment of reliable autonomous systems.

What changes

The prevailing intuition for managing LLM conceptual drift, relying on more formal constraints, is challenged, suggesting a need for alternative, potentially more dynamic, control mechanisms.

Winners
  • · AI agent developers
  • · Companies implementing autonomous workflows
  • · Researchers in AI collaboration
Losers
  • · Developers relying solely on rigid, constraint-based LLM management paradigms
  • · Systems unprepared for semantic drift
Second-order effects
Direct

Increased exploration and adoption of dynamic semantic control methods for AI agents.

Second

Accelerated development of more robust and less 'sickness-prone' self-managing AI architectures.

Third

Shift in AI development methodologies towards adaptive, learning-based control over static, rule-based systems, potentially simplifying complex AI deployments.
