Use when working with *.excalidraw or *.excalidraw.json files, user mentions diagrams/flowcharts, or requests architecture visualization - delegates all Excalidraw operations to subagents to prevent context exhaustion from verbose JSON (single files: 4k-22k tokens, can exceed read limits)

Excellent skill addressing a real problem: Excalidraw files consume 4k-22k tokens with poor signal-to-noise ratio. The description clearly triggers on file extensions and diagram keywords. Task knowledge is comprehensive with concrete templates for read/modify/create/compare operations, anti-patterns to avoid, and detailed token cost analysis (98% savings demonstrated). Structure is logical with quick reference tables and clear escalation from problem to solution. High novelty: this delegation pattern meaningfully prevents context exhaustion that a CLI agent would suffer (45% budget on single file). Minor improvement possible: could separate reference tables into a separate quick-reference file for very large skills, but current length is justified by the teaching component (overcoming agent rationalizations). The 'Common Rationalizations' section is particularly valuable for preventing agents from bypassing the delegation.
