At a glance

A skill your agent uses whenever the user wants to generate sound effects, ambient audio, or short audio clips from a text description.

  • The user wants to generate sound effects
  • SKILL.md covers Triggers, Quick Start, Arguments and Configuration, plus 5 more sections
  • Runs Python scripts from its folder; calls python3 and pip; reaches noiz.ai and storage.googleapis.com; needs NOIZ_API_KEY
  • Short audio clips from a text description

What it does

Sound Fx is an agent skill from NoizAI/skills. Use this skill whenever the user wants to generate sound effects, ambient audio, or short audio clips from a text description. Triggers include: any mention of 'sound effect', 'sfx', 'generate sound', 'make a sound', 'audio effect', 'ambient sound', 'foley', 'sound clip', 'noise', or requests to produce a specific sound (e.g. 'make a gunshot sound', 'generate thunder', 'create the sound of rain'). Also use when the user describes an action or scenario and wants the corresponding audio (e.g. 'someone getting…

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `ref_3rd_party.md` and `scripts/sfx.py`).

It sits in Media & Creative, covering Music and audio generation and Text to speech and voice. The repository describes itself as: Allow your 🦞 bot to Shout, Speak, with "human" vibe.

When your agent uses it

  • The user wants to generate sound effects
  • Short audio clips from a text description
  • Include: any mention of sound effect
  • Requests to produce a specific sound (e.g

Example prompts

  • “sound effect”
  • “generate sound”
  • “make a sound”
  • “/sound-fx”

Requirements

  • Python 3
  • A credential in NOIZ_API_KEY
  • A credential in YOUR_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 779f30a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • noiz.ai
    • storage.googleapis.com

    Also links to:

    • developers.noiz.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NOIZ_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sound Fx loads about 1.4k tokens when it runs. Until then it costs about 164 tokens; SKILL.md has 445 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~164
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 445 words (~1,365 tokens).

“Generate any sound effect from a text description — footsteps, explosions, cartoon boings, ambient rain, or whatever you can imagine.”
