Quality

Content

87%

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-crafted, concise skill that provides immediately actionable guidance for using the `sag` CLI tool. Its strengths are token efficiency and concrete examples with real commands and flags. The main weakness is the lack of error handling or validation guidance, particularly around API key issues, voice availability, or failed generations.

Suggestions

Add a brief error handling note (e.g., what to do if the API key is missing/invalid or if a voice ID isn't found) to improve workflow robustness.

DimensionReasoningScore

Conciseness

The content is lean and efficient. It assumes Claude knows how to use CLI tools and doesn't waste tokens explaining what TTS is or how APIs work. Every section delivers actionable information concisely.

3 / 3

Actionability

Provides concrete, copy-paste-ready commands throughout (e.g., `sag "Hello there"`, `sag -v Clawd -o /tmp/voice-reply.mp3 "Your message here"`). Specific flags, model names, voice IDs, and audio tags are all directly usable.

3 / 3

Workflow Clarity

The 'Chat voice responses' section has a clear two-step workflow (generate then include), but there's no validation or error handling guidance. For a tool that requires an API key and network calls, missing feedback on failures (invalid key, network errors, voice not found) is a gap. The pronunciation/delivery rules are listed but not sequenced as a troubleshooting workflow.

2 / 3

Progressive Disclosure

For a skill of this size and scope (under 50 lines, single-purpose CLI tool), the content is well-organized into logical sections (quick start, models, pronunciation, audio tags, voice responses) without needing external references. The built-in `sag prompting` command serves as a progressive disclosure mechanism for model-specific tips.

Description

22%

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 is extremely terse and reads more like a title than a functional skill description. It lacks concrete actions, explicit trigger guidance, and natural keyword coverage. While 'ElevenLabs' and 'text-to-speech' provide some specificity, the description fails to communicate what the skill actually does or when Claude should select it.

Suggestions

Add a 'Use when...' clause with trigger terms like 'text-to-speech', 'TTS', 'voice generation', 'read aloud', 'generate audio', 'ElevenLabs'.

List specific concrete actions such as 'Converts text to speech audio using ElevenLabs API, plays audio with macOS say-style interface, supports voice selection and audio file output'.

Expand natural keyword coverage to include variations users might say: 'speak', 'narrate', 'voice', 'audio output', 'speech synthesis', '.mp3'.

DimensionReasoningScore

Specificity

The description mentions 'text-to-speech' and 'mac-style say UX' but does not list any concrete actions like generating audio files, converting text, or specifying output formats. It's more of a label than a capability description.

1 / 3

Completeness

The description weakly addresses 'what' (text-to-speech) but completely lacks any 'when' clause or explicit trigger guidance. There is no 'Use when...' or equivalent instruction for Claude to know when to select this skill.

1 / 3

Trigger Term Quality

Includes 'text-to-speech' and 'ElevenLabs' which are relevant keywords a user might use, and 'say' references the macOS command. However, it misses common variations like 'TTS', 'voice generation', 'audio', 'speech synthesis', or 'read aloud'.

2 / 3

Distinctiveness Conflict Risk

Mentioning 'ElevenLabs' and 'mac-style say UX' provides some distinctiveness, but the description is too terse to clearly carve out a niche. It could overlap with other audio or TTS-related skills without clearer boundaries.
