Quality

Content

72%Weight 40%Scale 1-5

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

The skill body is concise and well-structured with clean one-level-deep references to real bundle files, but the STT workflow is stubbed with pseudocode placeholders and neither workflow includes validation checkpoints, capping actionability and workflow clarity at 3. Filling in the transcription snippet and adding verification steps would raise both.

Suggestions

Replace the Workflow 2 stub ('response = speech_client.recognize(...)') with a complete executable snippet, or at minimum inline the recognizer/config setup like tts.md does.

Add a verification step after generation (e.g. confirm the response contains inline_data audio bytes and save to .wav) and after transcription (e.g. check response.results before iterating), since batch/audio output is error-prone.

Make the Quick Start client construction explicit (e.g. note that genai.Client() picks up ADC) so the entry point is copy-paste ready.

DimensionReasoningScore

Conciseness

The ~35-line body is lean, assumes Claude's competence, and avoids explaining what TTS/STT or the SDKs are; every section earns its place with no padding.

5 / 5

Actionability

Workflow 1 is a complete executable snippet, but Workflow 2 is stubbed with '...' and 'See stt.md', and Quick Start leaves the client argument implicit; concrete guidance is present but incomplete.

3 / 5

Workflow Clarity

Workflows are numbered and sequenced, but there are no validation/verification checkpoints for batch transcription or audio output, and batch/destructive contexts cap clarity at 3 per the guideline.

3 / 5

Progressive Disclosure

The body is a clear overview with five well-signaled one-level-deep references, all of which exist as real files; content is appropriately split with easy navigation.

Description

66%Weight 40%Scale 1-5

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 specific and mostly distinctive, naming concrete TTS and STT capabilities, but it omits any explicit 'when to use' trigger guidance, which caps completeness at 3. Adding a 'Use when...' clause with natural trigger phrases would lift completeness and trigger-term quality.

Suggestions

Append an explicit trigger clause, e.g. 'Use when the user wants to generate speech, clone a voice, or transcribe/diarize audio with Google's Gemini-TTS or Chirp 3 models.'

Add common synonyms and concrete triggers (e.g. 'TTS', 'STT', 'voice generation', 'audio transcription', 'read text aloud') to broaden trigger-term coverage.

Optionally list a couple more concrete actions (e.g. 'streaming transcription', 'custom voice cloning') to push specificity toward 5.

DimensionReasoningScore

Specificity

Names the domain and several concrete capabilities ('Generate and transcribe speech', 'Text-to-Speech (Single/Multi-speaker)', 'Instant Custom Voice', 'Speech-to-Text (Transcription/Diarization)') with only minor gaps; not quite the exhaustive action list of a 5.

4 / 5

Completeness

Clearly answers 'what' (generate/transcribe speech, the four sub-features) but has no 'Use when...' clause or explicit trigger guidance, capping completeness at 3 per the guideline.

3 / 5

Trigger Term Quality

Includes natural terms users say (speech, Text-to-Speech, Speech-to-Text, transcription, voices) but lacks synonyms and file/extension-style triggers that a 5 anchor demands.

4 / 5

Distinctiveness Conflict Risk

The Gemini-TTS / Chirp 3 / Instant Custom Voice niche is fairly distinct with low overlap risk; only minor overlap with generic audio skills keeps it below 5.
