d2-diagram-creator

Quick Review

This skill is a template-based stub with minimal actual implementation. The description is too vague ('Create d2 diagram creator operations') for a CLI agent to understand what D2 is or when to invoke it. Task knowledge is essentially absent—there are no concrete steps, syntax examples, or D2-specific guidance (D2 is a declarative diagramming language, but nothing here explains its syntax, file format, or compilation). Structure is adequate as a basic template. Novelty is low-to-moderate: while D2 diagram generation could save tokens, this implementation provides no actual D2 knowledge, making it no more useful than asking a base LLM about D2. To improve: add D2 syntax primer, common diagram patterns (boxes, connections, labels), example .d2 files, and instructions for rendering diagrams.
