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, lean skill that exemplifies token efficiency and actionability. It provides exactly what Claude needs—executable commands and non-obvious configuration notes—without explaining concepts Claude already knows. The simplicity of the task is matched by appropriately minimal documentation.

Dimension	Reasoning	Score
Conciseness	Every token earns its place. No unnecessary explanations of what Whisper is or how speech-to-text works. The notes section contains only non-obvious, install-specific details.	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 there are no destructive or batch operations requiring 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 or referenced.	3 / 3

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 and distinct niche (local Whisper CLI transcription without an API key), which is its main strength. However, it lacks specific concrete actions, natural trigger terms users would say, and an explicit 'Use when...' clause, making it insufficient for Claude to reliably select this skill from a large pool.

Suggestions

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

Include natural trigger terms users would say: 'transcribe', 'audio', 'transcription', '.mp3', '.wav', '.m4a', 'subtitle', 'SRT', 'voice to text', 'convert audio to text'.

List specific concrete actions, e.g., 'Transcribes audio/video files to text, generates SRT/VTT subtitles, supports multiple languages and file formats using the local Whisper CLI.'

Dimension	Reasoning	Score
Specificity	Names the domain (speech-to-text) and the tool (Whisper CLI), and clarifies 'no API key' which is a useful detail, but doesn't 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 has no 'Use when...' clause or explicit trigger guidance, which per the rubric should cap completeness at 2, and since the 'what' is also quite thin, this lands at 1.	1 / 3
Trigger Term Quality	Includes 'speech-to-text', 'Whisper', and 'CLI' which are relevant keywords, 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 'speech-to-text', 'Whisper CLI', and 'no API key' creates a very specific niche that is unlikely to conflict with other skills. It clearly distinguishes itself from API-based transcription or other audio processing skills.	3 / 3
