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 to be effective for skill selection. It lacks specific actions, common trigger terms users would naturally use, and critically missing a 'Use when...' clause to guide Claude on when to select this skill.

Suggestions

Add a 'Use when...' clause such as 'Use when the user asks to convert text to speech, generate audio from text, or needs offline/local TTS without cloud APIs.'

Include common trigger term variations like 'TTS', 'speech synthesis', 'generate audio', 'read aloud', 'voice generation'.

List specific concrete actions such as 'Converts text to speech audio files, selects voice models, adjusts speech parameters using sherpa-onnx locally without cloud dependencies.'

Dimension	Reasoning	Score
Specificity	Names the domain (text-to-speech) and the tool (sherpa-onnx), and mentions key attributes (offline, no cloud), but does not list specific concrete actions like 'convert text to audio files', 'adjust voice parameters', or 'select language models'.	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 for when Claude should select this skill. Per rubric guidelines, missing 'Use when' caps completeness at 2, and the 'what' is also weak, so this scores 1.	1 / 3
Trigger Term Quality	Includes 'text-to-speech' and 'sherpa-onnx' which are relevant, but misses common user variations like 'TTS', 'speech synthesis', 'read aloud', 'generate audio', 'voice', or 'convert text to speech'.	2 / 3
Distinctiveness Conflict Risk	The combination of text-to-speech, sherpa-onnx, and offline/local constraints creates a very clear niche that is unlikely to conflict with other skills.	3 / 3

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 reasonably well-structured skill that is concise and well-organized for its scope. Its main weaknesses are the vague installation steps (no download URLs or specific commands) and the lack of any validation/verification steps to confirm the setup works. The usage section is concrete and actionable.

Suggestions

Add specific download URLs or commands for the runtime and voice model (e.g., `wget <url>` or a script reference) to make the install steps fully actionable.

Add a verification step after installation, such as `sherpa-onnx-tts --help` or a test command, to confirm the setup is working before proceeding to usage.

Dimension	Reasoning	Score
Conciseness	The content is lean and efficient. It doesn't explain what TTS is or how sherpa-onnx works internally. Every section serves a purpose: install, config, usage. The notes section is compact and covers edge cases without over-explaining.	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 scripts to execute. This leaves a critical step incomplete.	2 / 3
Workflow Clarity	The install → configure → use sequence is clear, but there are no validation checkpoints. There's no way to verify the runtime installed correctly, no test command to confirm the model works, and no error recovery guidance if the TTS command fails.	2 / 3
Progressive Disclosure	For a simple, single-purpose skill under 50 lines, the content is well-organized into clear sections (Install, Usage, Notes). No bundle files are provided, but the skill is compact enough that external references aren't needed. The structure is easy to scan.	3 / 3
