What is the 50% rule in MECW?

The 50% rule states that no more than half of an LLM's total context window should be filled with input content. This ensures the model has sufficient remaining 'working memory' for reasoning and generating accurate responses without hallucinating.

How does this skill prevent hallucinations?

It monitors 'context pressure'—the ratio of used tokens to the total window. When pressure exceeds the 50% MECW threshold, the skill alerts the user, as high pressure is statistically linked to increased model errors and hallucinations.

Can I integrate MECW monitoring into my own automated scripts?

Yes, the skill provides Python utilities like MECWMonitor and check_mecw_compliance that can be imported to handle token budgets programmatically in automated workflows.

What are the different pressure levels defined by this skill?

Pressure is categorized into four levels: LOW ( 70% - high hallucination risk requiring a context reset).

分析と監視

Optimizes LLM accuracy by monitoring context pressure and enforcing the 50% Maximum Effective Context Window rule to prevent hallucinations.

概要

This skill implements Maximum Effective Context Window (MECW) patterns to proactively manage token usage and maintain model reasoning quality. By enforcing the critical 50% rule—leaving half the context window available for reasoning and responses—it provides developers with real-time pressure monitoring, compliance checks, and automated warnings. It is essential for managing long-running sessions and data-heavy workflows where performance degradation typically occurs as context limits are approached.
