Validation for skill structure
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 specific tool and approach (local Whisper CLI without API key) which provides good distinctiveness, but lacks concrete action verbs and completely omits trigger guidance. It would benefit significantly from listing specific capabilities and adding explicit 'Use when...' conditions.
Suggestions
Add a 'Use when...' clause with trigger terms like 'transcribe audio', 'convert speech to text', 'audio file', or 'voice recording'
List specific actions such as 'Transcribes audio files, converts speech recordings to text, supports multiple audio formats'
Include common file extensions and natural user terms: '.mp3', '.wav', 'audio', 'recording', 'transcription'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (speech-to-text) and tool (Whisper CLI), and clarifies 'no API key', but doesn't list specific actions like transcribing audio files, converting formats, or handling different languages. | 2 / 3 |
Completeness | Describes what it does (speech-to-text with Whisper) 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 'speech-to-text' and 'Whisper CLI' which are relevant, but misses common user terms like 'transcribe', 'audio', 'voice', 'recording', '.mp3', '.wav', or 'convert speech'. | 2 / 3 |
Distinctiveness Conflict Risk | The combination of 'Whisper CLI', 'local', and 'no API key' creates a clear niche that distinguishes it from cloud-based transcription services or other audio processing skills. | 3 / 3 |
Total | 8 / 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, minimal skill that respects Claude's intelligence and token budget. It provides exactly what's needed: executable commands with practical flags, and brief notes about environment-specific details (cache location, default model). The skill exemplifies good design for simple CLI tools.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations about what Whisper is or how speech-to-text works. Every line provides actionable information Claude wouldn't inherently know (CLI flags, cache location, default model). | 3 / 3 |
Actionability | Provides copy-paste ready commands with real file paths and flags. Two concrete examples cover common use cases (transcription and translation with different output formats). | 3 / 3 |
Workflow Clarity | This is a simple, single-task skill (run a CLI command). The commands are unambiguous and self-contained. No multi-step process requiring validation checkpoints exists here. | 3 / 3 |
Progressive Disclosure | For a skill under 50 lines with no need for external references, the content is well-organized with clear sections (quick start, notes). No unnecessary splitting or monolithic walls of text. | 3 / 3 |
