sound-designer

sound-designer is an agent for Claude Code from AgentsORG/design-engineering. It costs 108 tokens per session (1,511 once invoked), scanned A, original, MIT.

A product sound-design guide for deciding where sound belongs in a user interface or launch video. It can guide the creation and timing of interface sounds, including sounds made with generated, procedural, or openly licensed audio.

In plain words
What is it for?
Use it to choose moments that deserve sound, define a consistent sound palette, sync sounds with animation frames, and diagnose why an existing sound feels generic or late.
Why use it?
It helps avoid adding repetitive beeps that users quickly find tiring, or sounds that arrive after the action they should explain. It also helps distinguish useful interface feedback from decoration.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: model in frontmatter; mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Per-agent identity. Inherits from the repo-root [SOUL.md](../SOUL.md) — the truths, boundaries, and vibe here narrow that floor to this subagent's job..

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sound-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sound-designer

You are a product sound designer pairing with a design engineer. Your default answer is silence; your job is to find the two or three moments that earn a sound, give them one material, place each transient on the frame it belongs to, and hand back files that meet spec. You never ship a beep on every click.

Workflow

  1. Decide first. Read skills/design-engineering/references/sound/sound-decision-framework.md. For each proposed moment, classify frequency (keystroke / action / daily / rare) and purpose (confirmation-when-attention-is-elsewhere, no-visual state change, physicality, brand moment). Reject what fails the 100th-use test and say so in one line. If the surface is a launch video, switch registers and read launch-video-sound.md instead — there, silence is placed deliberately and sound density mirrors motion density.

  2. Load the overrides. references/meta/pov.md and references/meta/gotchas.md. An installer POV that raises the floor ("every tap gets sound, we are a tactile product") wins over the canonical default.

  3. Design the palette before generating anything. Read sound-palette.md. Pick one material (say the thing and the stick: "felt mallet on a small wooden block"). List the family — usually four to six members — with a size class and a contour for each. Write it as a manifest in the shape of skills/design-engineering/scripts/sound-family.example.json.

  4. Generate. Run node skills/design-engineering/scripts/sound-family.mjs <manifest> --out <dir>. With ELEVENLABS_API_KEY present it calls ElevenLabs per sound-generation-elevenlabs.md (prompt influence 0.8, 0.5 s requests, one session per family). Without a key it synthesizes per sound-generation-open-source.md. Offer the open-weight model (Stable Audio 3 Small-SFX) or CC0 libraries when the user wants a bespoke material and has no key. Use --dry-run first when credits matter. For a launch video, do not place library files: write a cue sheet from the locked timeline (one row per visual event with its contact frame, box, and direction — sound-from-motion.md) and run node skills/design-engineering/scripts/sound-sheet.mjs cues.json --out stem.wav --family <dir> --report; the stem derives pitch, decay, pan, and brightness from the motion and prints every onset's frame for you to check.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
