Where should I put formatting rules like 'be concise'?

Formatting and tone rules belong in an Output Style (~/.claude/output-styles/). These function at the system prompt level, which has the highest priority in Claude's hierarchy.

What is the U-shaped attention pattern for instructions?

LLMs focus best on the beginning and end of a document. This skill organizes your configuration so safety guardrails are at the top and reference pointers are at the bottom.

Why is my CLAUDE.md file being ignored by Claude?

When CLAUDE.md exceeds 150-200 lines, LLMs often suffer from instruction fatigue. This skill helps you prune the file and move content to higher-priority tiers like Output Styles.

What is the difference between CLAUDE.md and .claude/rules/?

CLAUDE.md is for project-wide safety and core rules, while .claude/rules/ allows you to store topic-specific reference material that Claude auto-loads based on file paths.

Productivity & Workflow

Streamlines Claude Code project configurations by restructuring bloated CLAUDE.md files into high-priority instruction tiers.

This skill provides a systematic framework for auditing and optimizing Claude Code configuration files that have become ineffective or exceed the 150-line performance threshold. By leveraging Claude's internal priority hierarchy, it helps you redistribute instructions across output styles, project rules, and global configurations. This ensures that critical safety guardrails and formatting preferences are correctly prioritized, preventing instruction fatigue and ensuring Claude follows project-specific rules with high reliability.
