Systematic methodology to reduce skill file size through externalization,
consolidation, and progressive loading patterns.
Triggers: large skill, skill optimization, skill size, 300 lines, inline code,
skill refactoring, skill context reduction, skill modularization
Use when: skills exceed 300 lines, multiple code blocks (10+) with similar
functionality, heavy Python inline with markdown, functions >20 lines embedded
DO NOT use when: skill is under 300 lines and well-organized.
DO NOT use when: creating new skills - use modular-skills instead.
Consult this skill when skills-eval shows "Large skill file" warnings.
