# Splitting Notes ## Overview Split large monolithic note files into focused, single-topic files with index-based navigation. Reduces cognitive load and improves discoverability through progressive grouping. ## When to Use ```dot digraph when_refactor { "Note file size > 1000 lines?" [shape=diamond]; "Topics mixing unrelated concepts?" [shape=diamond]; "Hard to find specific information?" [shape=diamond]; "Refactor notes" [shape=box]; "Keep as-is" [shape=box]; "Note file size > 1000 lines?" -> "Refactor notes" [label="yes"]; "Note file size > 1000 lines?" -> "Topics mixing unrelated concepts?" [label="no"]; "Topics mixing unrelated concepts?" -> "Refactor notes" [label="yes"]; "Topics mixing unrelated concepts?" -> "Hard to find specific information?" [label="no"]; "Hard to find specific information?" -> "Refactor notes" [label="yes"]; "Hard to find specific information?" -> "Keep as-is" [label="no"]; } ``` **Use when:** - Note files exceed 1000 lines - Single file mixes unrelated topics - Navigation and search are difficult - Content needs better organization **Don't use when:** - Files are already under 500 lines - Topics are tightly coupled - Splitting would harm coherence ## Prerequisite **Complex multi-step refactoring** - Must complete planning phase first. If not currently in **plan mode**, invoke `EnterPlanMode` before starting. - **In plan mode**: Complete analysis and create migration plan - **After plan mode**: Execute split and v
