Validation for skill structure
Discovery
100%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 is an excellent skill description that excels across all dimensions. It provides specific actions, comprehensive trigger terms covering both natural language and technical terminology, explicit use/don't-use guidance, and clear boundaries with other skills. The DO NOT USE FOR section with skill cross-references is particularly effective for disambiguation.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple concrete actions: 'Build and deploy GitHub Copilot SDK apps to Azure', 'scaffold copilot project', 'deploy copilot app', 'host on azure'. Also mentions specific technical components like 'CopilotClient', 'createSession', 'sendAndWait'. | 3 / 3 |
Completeness | Clearly answers both what ('Build and deploy GitHub Copilot SDK apps to Azure') and when with explicit 'USE FOR:' and 'DO NOT USE FOR:' clauses that provide comprehensive trigger guidance and boundary conditions. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'build copilot app', 'create copilot app', 'copilot SDK', 'bring your own model', 'BYOM', 'use my own model', 'chat app with copilot'. Includes both casual phrases and technical terms like '@github/copilot-sdk' and 'DefaultAzureCredential'. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with explicit exclusions ('DO NOT USE FOR: Copilot Extensions, Azure Functions without Copilot, Foundry agent hosting') and cross-references to related skills ('use microsoft-foundry skill'). Clear niche focused specifically on Copilot SDK development. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an exemplary skill file that demonstrates excellent token efficiency through routing tables, clear actionable commands, and well-organized progressive disclosure. The workflow is clear with explicit step sequencing and appropriate delegation to reference files for detailed implementation guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. Uses tables for routing decisions, minimal prose, and delegates details to reference files. Every token serves a purpose with no explanation of concepts Claude already knows. | 3 / 3 |
Actionability | Provides concrete, executable commands (azd init with specific template), clear routing tables for decision-making, and specific configuration patterns. The scaffold command is copy-paste ready. | 3 / 3 |
Workflow Clarity | Clear numbered steps with explicit routing table at the start. Step 4 explicitly sequences deployment through three skills in order. The workflow handles multiple entry points cleanly with clear branching. | 3 / 3 |
Progressive Disclosure | Excellent structure with concise overview and well-signaled one-level-deep references to detailed docs (copilot-sdk.md, deploy-existing.md, azure-model-config.md). Appropriately delegates complexity to reference files. | 3 / 3 |
Total | 12 / 12 Passed |
