sound-effects

Generate sound effects from text descriptions using ElevenLabs. Use when creating sound effects, generating audio textures, producing ambient sounds, cinematic impacts, UI sounds, or any audio that isn't speech. Supports looping, duration control, and prompt influence tuning.

Quality

Content

88%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.

A tight, highly actionable skill body with runnable code across three languages, a clear parameter reference, and a properly linked installation reference. The only weakness is moderate verbosity from the inline output-format list that could live in a reference file.

Suggestions

Move the full output-format enumeration (line 95) into a references file (e.g. references/output-formats.md) and keep only the default plus a pointer inline, improving both conciseness and progressive_disclosure.

Consider relocating the detailed Parameters table to a reference once it grows, leaving the Quick Start as the primary inline payload.

Add a one-line note in Error Handling linking to the installation reference for API-key/401 troubleshooting to keep the main body focused on generation.

Dimension	Reasoning	Score
Conciseness	The body is lean with no concept padding and assumes Claude's competence, but the full enumeration of ~20 output-format strings (line 95) is a token cost that could be trimmed or moved to a reference, keeping it just below the top anchor.	4 / 5
Actionability	Fully executable, copy-paste-ready code is provided in Python, JavaScript, and cURL, plus a parameterized examples block and an error-handling snippet — covering the common cases concretely.	5 / 5
Workflow Clarity	This is a simple single-purpose skill (one API call) where the action is unambiguous; the simple-skill exception applies and no destructive/batch validation is required, so it earns the top score.	5 / 5
Progressive Disclosure	Good structure with well-signaled one-level-deep reference to the existing references/installation.md, but the long output-format enumeration and parameter details inline represent a minor organization gap rather than the ideal split of the top anchor.	4 / 5

Description

100%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.

A textbook-quality description that pairs a concrete capability statement with an explicit, trigger-rich 'Use when' clause and a sharp boundary against speech skills. It mirrors the rubric's top-anchor example closely with no vagueness or over-claiming.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Generate sound effects', 'creating sound effects, generating audio textures, producing ambient sounds, cinematic impacts, UI sounds', plus 'looping, duration control, and prompt influence tuning' — giving comprehensive coverage rather than 1-2 actions.	5 / 5
Completeness	Explicitly answers both 'what' ('Generate sound effects from text descriptions using ElevenLabs') and 'when' ('Use when creating sound effects...') with concrete trigger phrases, matching the top anchor exactly.	5 / 5
Trigger Term Quality	Comprehensive natural-term coverage with synonyms ('sound effects', 'audio textures', 'ambient sounds', 'cinematic impacts', 'UI sounds') plus the catch-all 'any audio that isn't speech' — terms a user would naturally say.	5 / 5
Distinctiveness Conflict Risk	Clear niche with an explicit boundary — 'any audio that isn't speech' — that cleanly distinguishes it from TTS/speech skills, giving minimal conflict risk.	5 / 5
