File Refactor Skill

This skill optimizes file sizes by extracting types, utilities, hooks/components, formatters, and constants into separate focused modules. Default target: keep files under 600 lines unless the repo documents a different limit.

When to Trigger

• File exceeds 600 lines (or the repo's documented limit)
• Module has mixed concerns (types, utils, handlers, rendering, constants in one file)
• Screen/component has inline sub-components that could be extracted
• Python service has long pure helpers, dataclasses, or CLI subcommands mixed with orchestration
• File has long utility functions that could be separated
• You need to decouple a monolithic file
