Quality

Content

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 provides executable commands, avoids explaining concepts Claude already knows, and includes just enough operational notes (cache location, default model) to be useful. The only minor improvement would be using markdown headers (##) instead of plain text for 'Quick start' and 'Notes' sections for better structure.

DimensionReasoningScore

Conciseness

Very lean and efficient. No unnecessary explanations of what Whisper is or how speech-to-text works. Every line provides actionable information Claude wouldn't inherently know (CLI flags, cache path, default model).

3 / 3

Actionability

Provides fully executable, copy-paste-ready commands with real flags and file paths. The two 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 the notes provide relevant operational context (model caching, defaults). No multi-step process or destructive operations require validation checkpoints.

3 / 3

Progressive Disclosure

For a simple 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 scope.

Description

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 is too terse. It lacks specific actions the skill can perform and entirely omits explicit trigger guidance ('Use when...'), making it harder for Claude to know when to select it from a large skill set.

Suggestions

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

List specific concrete actions such as 'Transcribes audio/video files, generates subtitles/SRT files, supports multiple languages and output formats.'

Include natural trigger terms users would say: 'transcribe', 'audio', 'transcription', '.mp3', '.wav', 'voice to text', 'subtitles'.

DimensionReasoningScore

Specificity

Names the domain (speech-to-text) and the tool (Whisper CLI), and clarifies 'no API key', but does not list specific concrete 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 completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric, missing 'Use when' caps completeness at 2, and the 'what' is also weak, so this scores 1.

1 / 3

Trigger Term Quality

Includes useful terms like 'speech-to-text', 'Whisper', and 'CLI', but misses common user-facing variations such as 'transcribe', 'audio', 'transcription', '.wav', '.mp3', 'subtitles', or 'voice to text'.

2 / 3

Distinctiveness Conflict Risk

The combination of 'speech-to-text', 'Whisper CLI', and 'no API key' creates a very clear niche that is unlikely to conflict with other skills. It's distinctly about local Whisper-based transcription.
