Context Optimizer

About

Context Optimizer is a specialized Claude Code skill designed to manage and reduce token usage during complex development tasks. By adhering to MECW (Minimal Essential Context Window) principles, it monitors context pressure and triggers optimization strategies when usage exceeds 50% of the window. It facilitates subagent-based workflows and selective data reading to prevent context saturation, ensuring Claude remains performant and accurate during long-running or multi-file operations. The skill includes automated lifecycle hooks to audit context usage and provides strategies for handling large command outputs via file references.

Key Features

• MECW-compliant task decomposition and subagent coordination
• Dynamic token budget allocation across specialized modules
• Detailed audit logging via PreToolUse and PostToolUse lifecycle hooks
• Proactive context monitoring and pressure assessment
• Intelligent large output handling using file references to avoid truncation
• 123 GitHub stars

Use Cases

• Analyzing large build or test logs using selective file reading techniques like head, tail, and grep
• Managing multi-file code analyses and long-running tool chains without hitting context limits
• Decomposing complex architectural refactors into modular sub-tasks for better token efficiency
