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.

Content

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

A well-organized, highly actionable skill body with executable examples in multiple languages and solid error guidance. The main weakness is a large inline reference enumeration that could be split into a referenced file.

Suggestions

Move the full output-format enumeration (the "Full list: mp3_22050_32, ..." line) into a dedicated reference file and link to it, keeping only the common formats inline in the table.

Add a one-line note in the Quick Start confirming authentication is handled via ELEVENLABS_API_KEY so users know the setup prerequisite before running the first example.

Dimension	Reasoning	Score
Conciseness	The body is lean with executable code in three languages, compact parameter/format tables, and no explanation of concepts Claude already knows; the inline format list is concrete reference data rather than padding.	3 / 3
Actionability	Fully executable Python, JavaScript, and cURL snippets plus a parameter table with types/defaults and copy-paste-ready examples with parameters make the guidance directly usable.	3 / 3
Workflow Clarity	As a simple single-task skill the setup→convert→save flow is unambiguous, and the error-handling section enumerates 401/422/429 recovery guidance; no destructive/batch step requires an explicit validate-retry loop.	3 / 3
Progressive Disclosure	There is one real, clearly signaled one-level reference (references/installation.md, linked in both the setup note and References section), but the long inline enumeration of every output format string is content that would fit better in a separate reference file.	2 / 3

Description

100%

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 strong, third-person description that pairs concrete capabilities with an explicit, diverse trigger clause and a clear non-speech niche. It answers both what and when without padding.

Dimension	Reasoning	Score
Specificity	"Generate sound effects from text descriptions" and "Supports looping, duration control, and prompt influence tuning" list multiple concrete, specific actions rather than vague domain mention.	3 / 3
Completeness	It states what the skill does (generate sound effects from text via ElevenLabs) and gives an explicit "Use when..." trigger clause answering when to invoke it.	3 / 3
Trigger Term Quality	"creating sound effects, generating audio textures, producing ambient sounds, cinematic impacts, UI sounds, or any audio that isn't speech" gives broad coverage of natural terms a user would actually say.	3 / 3
Distinctiveness Conflict Risk	The non-speech audio niche and the "audio that isn't speech" qualifier clearly separate it from TTS/speech skills, making wrong-skill triggering unlikely.	3 / 3
	Total	12 / 12 Passed
