Discovery
0%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is critically underdeveloped, providing almost no useful information for skill selection. It lacks specific actions, natural trigger terms, explicit use cases, and any distinguishing characteristics that would help Claude choose this skill appropriately from a pool of alternatives.
Suggestions
Add specific concrete actions the skill performs (e.g., 'Scaffolds new projects, configures build systems, sets up directory structures, integrates dependencies').
Include a 'Use when...' clause with natural trigger terms users would say (e.g., 'Use when the user wants to create a new app, start a project, scaffold an application, or set up a codebase').
Specify the type of applications or technologies covered to distinguish from other development-related skills (e.g., 'web applications', 'React projects', 'Python CLI tools').
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description uses vague, abstract language ('orchestrator') without listing any concrete actions. It does not specify what the skill actually does beyond the generic term 'building.' | 1 / 3 |
Completeness | Missing both 'what' (no specific actions listed) and 'when' (no trigger guidance or use cases). The description fails to answer either question meaningfully. | 1 / 3 |
Trigger Term Quality | Contains no natural keywords users would say. 'Orchestrator' is technical jargon, and 'main application building' is not how users naturally phrase requests. | 1 / 3 |
Distinctiveness Conflict Risk | 'Application building' is extremely generic and could conflict with any skill related to coding, development, project setup, or software creation. No distinct niche is established. | 1 / 3 |
Total | 4 / 12 Passed |
Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill excels at organization and token efficiency, serving as a clean orchestration hub with excellent progressive disclosure through its content map and template tables. However, it lacks concrete executable guidance for the actual orchestration process and misses validation checkpoints that would be critical for coordinating multi-agent workflows on complex application builds.
Suggestions
Add concrete commands or code showing how to invoke agent coordination (e.g., specific tool calls or command patterns)
Include validation checkpoints in the workflow example, such as 'Verify schema before proceeding to API routes' or 'Run type-check after frontend generation'
Add a brief error recovery section for when agent coordination fails mid-process
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. Uses tables for quick scanning, no unnecessary explanations of concepts Claude knows. Every section serves a clear purpose with minimal prose. | 3 / 3 |
Actionability | Provides good structural guidance with clear file references and template links, but the usage example is illustrative rather than executable. No concrete commands or code snippets for actually invoking the orchestration process. | 2 / 3 |
Workflow Clarity | The usage example shows a numbered process flow, but lacks explicit validation checkpoints or error handling steps. For an orchestrator coordinating multiple agents on complex builds, there should be verification steps between agent handoffs. | 2 / 3 |
Progressive Disclosure | Excellent structure with clear content map, one-level-deep references to specific files, and well-organized tables. The 'When to Read' column provides perfect navigation guidance for selective reading. | 3 / 3 |
Total | 10 / 12 Passed |
Validation
90%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
