Validation for skill structure
Discovery
32%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 the core technology (ElevenLabs TTS) and references a UX pattern but lacks explicit trigger guidance and comprehensive action verbs. It's too terse to reliably guide skill selection among multiple options, and the absence of a 'Use when...' clause significantly limits its effectiveness.
Suggestions
Add a 'Use when...' clause with trigger terms like 'speak', 'read aloud', 'TTS', 'voice generation', 'audio output'
List specific actions such as 'Convert text to speech audio', 'Generate voice files', 'Speak text aloud using ElevenLabs voices'
Include common user phrases and file types like '.mp3', 'audio file', 'voice synthesis' to improve trigger term coverage
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (text-to-speech) and references a specific service (ElevenLabs) and UX pattern (mac-style say), but doesn't list concrete actions like 'convert text to audio', 'generate voice files', or 'speak text aloud'. | 2 / 3 |
Completeness | Provides a brief 'what' (text-to-speech with ElevenLabs) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes 'text-to-speech' and 'ElevenLabs' which are relevant, but misses common natural terms users would say like 'TTS', 'voice', 'audio', 'speak', 'read aloud', or 'generate speech'. | 2 / 3 |
Distinctiveness Conflict Risk | ElevenLabs is a specific service which helps distinguish it, but 'text-to-speech' is broad enough to potentially conflict with other TTS or audio skills without clearer trigger boundaries. | 2 / 3 |
Total | 7 / 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 excellent skill file that exemplifies token efficiency while maintaining full actionability. It assumes Claude's competence with CLI tools and APIs, provides concrete examples throughout, and organizes information logically for quick reference. The inclusion of the 'Chat voice responses' workflow with specific voice character tips adds practical value.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what TTS is or how APIs work. Every line provides actionable information Claude needs. | 3 / 3 |
Actionability | Provides concrete, copy-paste ready commands throughout. Examples are executable (`sag "Hello there"`, `sag -v Clawd -o /tmp/voice-reply.mp3`), and specific tags/flags are clearly documented. | 3 / 3 |
Workflow Clarity | For this simple CLI tool, the workflow is appropriately clear. The 'Chat voice responses' section shows a clear two-step process (generate then include). The 'Pronunciation + delivery rules' section provides a logical troubleshooting sequence (first fix respelling, then normalization, then language). | 3 / 3 |
Progressive Disclosure | Well-organized with clear sections. For a skill under 50 lines with no need for external references, the structure is appropriate. Quick start, model notes, rules, and special use cases are logically separated. | 3 / 3 |
Total | 12 / 12 Passed |
