Quality

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 niche (local Whisper CLI speech-to-text) which makes it distinctive, but it lacks specific actions, natural trigger terms users would say, and an explicit 'Use when...' clause. It reads more like a tagline than a functional skill description that would help Claude select it appropriately.

Suggestions

Add a 'Use when...' clause with explicit triggers, e.g., 'Use when the user wants to transcribe audio or video files locally, generate subtitles, or convert speech to text without an API key.'

List concrete actions such as 'Transcribes audio/video files, generates SRT/VTT subtitles, supports multiple languages and formats (.mp3, .wav, .m4a).'

Include natural user terms like 'transcribe', 'audio', 'transcription', 'subtitle', 'voice to text', '.mp3', '.wav' to improve trigger term coverage.

DimensionReasoningScore

Specificity

Names the domain (speech-to-text) and the tool (Whisper CLI), and notes 'no API key', but doesn't list specific actions like transcribing audio files, generating subtitles, converting formats, etc.

2 / 3

Completeness

Describes what at a high level (speech-to-text with Whisper CLI) but has no 'Use when...' clause or explicit trigger guidance, which per the rubric should cap completeness at 2, and the 'what' is also quite thin, placing this at 1.

1 / 3

Trigger Term Quality

Includes 'speech-to-text', 'Whisper', and 'CLI' which are relevant, but misses common user terms like 'transcribe', 'audio', 'transcription', '.mp3', '.wav', 'subtitle', 'SRT', or 'voice to text'.

2 / 3

Distinctiveness Conflict Risk

The combination of 'Whisper CLI', 'local', and 'no API key' creates a clear niche that is unlikely to conflict with other skills such as cloud-based transcription or general audio processing.

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 does exactly what it needs to. It's concise, actionable, and well-structured for a simple CLI tool. The two example commands cover the main use cases (transcribe and translate) with different output formats, and the notes add only non-obvious, environment-specific information.

DimensionReasoningScore

Conciseness

Extremely lean — no unnecessary explanations, no description of what Whisper is or how speech-to-text works. Every line adds value. The notes section is brief and contains only non-obvious, install-specific details.

3 / 3

Actionability

Provides fully executable, copy-paste-ready commands with realistic flags and file paths. Two concrete examples cover the primary use cases (transcription and translation) with different output formats.

3 / 3

Workflow Clarity

This is a simple, single-purpose skill (run a CLI command). The single action is unambiguous, and there's no multi-step or destructive process that would require validation checkpoints.

3 / 3

Progressive Disclosure

For a skill under 50 lines with no need for external references, the content is well-organized into a quick start section and notes. No bundle files are needed for this simple CLI wrapper skill.
