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 (offline TTS via sherpa-onnx) which makes it distinctive, but it is too terse—lacking specific actions, natural trigger terms users would say, and an explicit 'Use when...' clause. It reads more like a label than a functional description that would help Claude select it from a large skill set.

Suggestions

Add a 'Use when...' clause with explicit triggers, e.g., 'Use when the user asks to convert text to audio, generate speech, read text aloud, or mentions TTS, voice synthesis, or sherpa-onnx.'

List specific concrete actions such as 'Converts text to speech audio files, supports multiple voices/languages, generates WAV/MP3 output' to improve specificity.

Include common natural-language trigger terms like 'TTS', 'read aloud', 'generate audio', 'speech', 'voice' to improve discoverability.

DimensionReasoningScore

Specificity

Names the domain (text-to-speech) and the tool (sherpa-onnx), and clarifies it's offline/local, but doesn't list specific concrete actions like 'convert text to audio files', 'generate speech from documents', etc.

2 / 3

Completeness

Provides a brief 'what' (text-to-speech via sherpa-onnx) but completely lacks a 'Use when...' clause or any explicit trigger guidance, which per the rubric caps completeness at 2, and the 'what' itself is thin enough to warrant a 1.

1 / 3

Trigger Term Quality

Includes 'text-to-speech' and 'sherpa-onnx' which are relevant, but misses common user terms like 'TTS', 'read aloud', 'generate audio', 'speech synthesis', 'convert text to speech', or 'voice'.

2 / 3

Distinctiveness Conflict Risk

Text-to-speech via a specific tool (sherpa-onnx) with the offline qualifier is a clear, distinct niche that is unlikely to conflict with other skills.

Implementation

72%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-structured, concise skill for local TTS setup. Its main weakness is the vague installation step—lacking specific download URLs or commands—which undermines actionability. Adding concrete download instructions and a quick verification step would significantly improve it.

Suggestions

Provide specific download URLs or commands for the runtime and voice model (e.g., `wget <url>` or a link to the releases page) instead of the vague 'Download the runtime for your OS'.

Add a verification step after installation, such as `sherpa-onnx-tts --help` or a test command to confirm the runtime and model are correctly installed.

DimensionReasoningScore

Conciseness

The content is lean and efficient. No unnecessary explanations of what TTS is or how sherpa-onnx works internally. Every section serves a clear purpose and there's no padding.

3 / 3

Actionability

The usage command is concrete and copy-paste ready, and the config JSON is specific. However, the install section is vague—'Download the runtime for your OS' and 'Download a voice model' lack specific URLs, commands, or download instructions, leaving the user guessing.

2 / 3

Workflow Clarity

The install → configure → use sequence is present and logical, but there are no validation checkpoints (e.g., verify the runtime extracted correctly, test that the model loads). For a multi-step setup process, explicit verification steps would improve reliability.

2 / 3

Progressive Disclosure

For a simple, single-purpose skill under 50 lines, the content is well-organized into clear sections (Install, Usage) with notes for advanced overrides. No unnecessary nesting or monolithic walls of text.
