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.

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

This is a solid, actionable skill with executable examples across multiple languages and well-documented parameters. Its main weakness is token efficiency — the exhaustive output format list, basic error handling patterns, and triple-language examples add bulk without proportional value. The skill would benefit from trimming the output formats to the key ones and moving the full list to a reference file.

Suggestions

Move the full output format list to a reference file and keep only the 4 main formats in the SKILL.md body

Remove or significantly trim the error handling section — Claude already knows try/except patterns and HTTP error codes

Consider showing only one primary language example in Quick Start and referencing others in a separate file to reduce token usage

Dimension	Reasoning	Score
Conciseness	Generally efficient but includes some unnecessary content: the full list of output formats is excessive, the error handling section is basic knowledge Claude already has, and showing three language examples (Python, JS, cURL) for the same operation adds bulk. The prompt tips section, while useful, could be more concise.	2 / 3
Actionability	Provides fully executable, copy-paste ready code in Python, JavaScript, and cURL. Parameters are clearly documented in a table with types, defaults, and constraints. Examples with parameters show concrete usage patterns for different scenarios.	3 / 3
Workflow Clarity	This is a single-task skill (generate sound effect from text) with no multi-step destructive operations. The workflow is unambiguous: create client, call convert with parameters, write output to file. Error handling with common error codes provides adequate validation guidance for an API call.	3 / 3
Progressive Disclosure	References an installation guide at references/installation.md (though no bundle files confirm its existence), but the main content includes a lot of inline detail (full output format list, all parameter variations) that could be split into reference files. The structure is reasonable but the output formats section especially bloats the main file.	2 / 3

Description

100%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is an excellent skill description that hits all the marks. It clearly states what the skill does (generate sound effects from text via ElevenLabs), when to use it (with an explicit 'Use when' clause covering multiple natural trigger scenarios), and distinguishes itself from speech-related audio skills. The inclusion of specific capability details like looping and duration control adds useful specificity without being verbose.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions: generating sound effects from text descriptions, looping, duration control, and prompt influence tuning. Also enumerates specific types of outputs (audio textures, ambient sounds, cinematic impacts, UI sounds).	3 / 3
Completeness	Clearly answers both 'what' (generate sound effects from text descriptions using ElevenLabs with looping, duration control, prompt influence tuning) and 'when' (explicit 'Use when' clause listing multiple trigger scenarios including sound effects, audio textures, ambient sounds, etc.).	3 / 3
Trigger Term Quality	Excellent coverage of natural terms users would say: 'sound effects', 'audio textures', 'ambient sounds', 'cinematic impacts', 'UI sounds', 'audio that isn't speech'. Also includes the tool name 'ElevenLabs' which users might reference directly.	3 / 3
Distinctiveness Conflict Risk	Highly distinctive with a clear niche: non-speech audio generation via ElevenLabs. The explicit exclusion 'any audio that isn't speech' helps differentiate from TTS/voice synthesis skills, and the specific tool mention (ElevenLabs) further reduces conflict risk.	3 / 3
