Quality

Content

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 for local TTS that is concise and well-organized. Its main weakness is the vague installation instructions—lacking specific download URLs or commands—which undermines actionability. Adding a verification step (e.g., testing the binary runs) would improve workflow clarity.

Suggestions

Provide specific download URLs or commands for the runtime and voice model (e.g., `wget <url>` or a script reference) 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 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 underspecified.	2 / 3
Workflow Clarity	The sequence (install → configure → use) is clear and logical. However, there are no validation checkpoints—no way to verify the runtime installed correctly, that the model is in the right place, or that the config is valid before attempting to generate speech.	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, and the skill doesn't need external references given its scope.	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 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 the skill can perform and entirely omits a 'Use when...' clause, making it hard for Claude to know when to select it over other skills.

Suggestions

Add a 'Use when...' clause with trigger terms like 'Use when the user asks to convert text to speech, generate audio from text, TTS, speech synthesis, or read text aloud offline'.

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

Include common user-facing synonyms and variations like 'TTS', 'speech synthesis', 'generate audio', 'voice generation', 'read aloud'.

Dimension	Reasoning	Score
Specificity	Names the domain (text-to-speech) and the tool (sherpa-onnx), and mentions key characteristics (offline, no cloud), but does not list specific concrete actions like 'convert text to audio files', 'adjust speech rate', etc.	2 / 3
Completeness	Provides a brief 'what' (text-to-speech via sherpa-onnx) but completely lacks any 'Use when...' clause or explicit trigger guidance for when Claude should select this skill.	1 / 3
Trigger Term Quality	Includes 'text-to-speech' and 'sherpa-onnx' which are relevant keywords, but misses common user variations like 'TTS', 'speech synthesis', 'read aloud', 'generate audio', or 'voice output'.	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
