64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid reference skill with excellent actionability — nearly every section provides complete, executable code examples for CIM symbol creation. The main weaknesses are its length (could benefit from splitting into overview + detailed reference files) and the lack of any workflow guidance around testing/validating symbols. The content is well-organized but could be more token-efficient by consolidating some repetitive structural patterns.
Suggestions
Split detailed examples (line symbols, polygon symbols, animations) into separate reference files and keep SKILL.md as a concise overview with one basic example and clear links to each detailed file.
Add a brief workflow section explaining how to test/validate CIM symbols (e.g., 'Apply symbol to a test graphic, verify rendering in MapView, check console for CIM parsing errors').
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is largely code examples which are useful, but the initial 'CIM Symbol Basics' bullet list is somewhat redundant given the description and the examples that follow. The file is quite long (~350 lines) and some examples could be consolidated. However, it avoids explaining basic concepts Claude would know. | 2 / 3 |
Actionability | The skill provides fully executable, copy-paste ready JavaScript/TypeScript code for every symbol type discussed. Examples are concrete with specific property values, color arrays, and complete object structures. The numbered marker, arrow line, hatched fill, and data-driven examples are all directly usable. | 3 / 3 |
Workflow Clarity | This is primarily a reference/recipe skill rather than a multi-step workflow, so explicit sequencing is less critical. However, there's no guidance on the process of creating and validating CIM symbols (e.g., how to test them, debug rendering issues, or verify correctness). The 'Common Pitfalls' section hints at validation concerns but doesn't provide verification steps. | 2 / 3 |
Progressive Disclosure | The content is well-organized with clear section headers and progresses from basic to advanced (point → line → polygon → animation → data-driven). However, at ~350 lines this is quite long and could benefit from splitting detailed examples into separate reference files. The 'Reference Samples' section at the end provides some navigation but the main content is monolithic. | 2 / 3 |
