Discovery
40%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description identifies a clear, distinctive niche (GLSL shaders for JARVIS-style holographic effects) but lacks actionable detail. It fails to specify concrete capabilities and completely omits trigger guidance, making it difficult for Claude to know when to select this skill over others.
Suggestions
Add a 'Use when...' clause with trigger terms like 'shader', 'GLSL', 'holographic UI', 'graphics effects', 'WebGL', or 'visual effects'
List specific concrete actions such as 'Create fragment and vertex shaders, implement glow effects, animate holographic displays, debug shader compilation errors'
Include common keyword variations users might say: 'graphics programming', 'WebGL shaders', '3D effects', 'visual effects code'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (GLSL shader programming) and a specific application (JARVIS holographic effects), but doesn't list concrete actions like 'create shaders', 'debug rendering', or 'optimize performance'. | 2 / 3 |
Completeness | Only addresses 'what' at a high level (GLSL shader programming for holographic effects) but completely lacks any 'Use when...' clause or explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes relevant keywords like 'GLSL', 'shader', and 'holographic', but misses common variations users might say like 'graphics programming', 'WebGL', 'fragment shader', 'vertex shader', or 'visual effects'. | 2 / 3 |
Distinctiveness Conflict Risk | The combination of 'GLSL shader programming' with 'JARVIS holographic effects' is highly specific and unlikely to conflict with other skills - it targets a clear niche of graphics programming for a particular visual style. | 3 / 3 |

Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong skill document with excellent actionability and workflow clarity. The TDD-first approach with explicit verification steps is well-executed, and the code examples are complete and executable. The main weakness is moderate verbosity - some explanations of basic GLSL concepts and performance patterns could be more concise given Claude's existing knowledge.
Suggestions
Trim explanatory text in sections 5.1-5.6 - the code examples are self-explanatory and the prose descriptions of why branching is bad or what precision qualifiers do are unnecessary for Claude
Remove or condense the Technology Stack section (4.1-4.2) - Claude knows GLSL versions and basic shader setup
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary explanations (e.g., explaining what precision qualifiers are, basic GLSL concepts Claude would know). The overview section and some table explanations could be tightened. | 2 / 3 |
Actionability | Excellent actionability with fully executable GLSL code examples, complete TypeScript test examples, specific bash commands for verification, and copy-paste ready shader implementations for multiple use cases. | 3 / 3 |
Workflow Clarity | Clear 4-step TDD workflow with explicit validation checkpoints (Step 4 verification commands), pre-implementation checklists organized by phase, and feedback loops for error recovery. The workflow is well-sequenced with clear validation gates. | 3 / 3 |
Progressive Disclosure | Well-organized with clear sections progressing from overview to implementation to advanced patterns. References external file (references/advanced-patterns.md) appropriately, and content is logically structured with numbered sections for easy navigation. | 3 / 3 |

Validation
75%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
