When is the best time to use the /compact command?

You should run /compact after completing a distinct phase of work, after heavy browser automation, or when switching focus to a different part of the codebase.

How can I check what is filling up my current session?

Use the /context-analyzer:analyze-context command to parse your project's JSONL history and get a detailed breakdown of token consumption by category.

What is the biggest consumer of context in Claude Code?

Surprisingly, message metadata and progress streaming can account for 50-70% of context. Large uncompressed PNG screenshots are the next biggest contributor.

Why is 'Edit' more context-efficient than 'Write'?

The Edit tool only sends specific string changes into the context, whereas the Write tool sends the entire file content, which can quickly fill your window if used repeatedly on large files.

Optimizes Claude Code session efficiency by identifying context consumers and providing strategies to minimize token bloat.

Context Optimization is a specialized skill designed to help developers manage Claude Code's finite context window. It provides a comprehensive framework for diagnosing what consumes tokens—ranging from hidden message metadata and progress events to large image payloads and redundant file reads. By offering actionable strategies like screenshot compression, optimized Bash usage, and proactive compaction patterns, this skill ensures that your coding sessions remain productive longer and prevents the common 'context full' errors that disrupt complex workflows.
