What is soundscape-builder?

A Foundry VTT soundscape configurator for the fvtt-mod-soundscape module. It combines continuous background audio with occasional sounds separated by random quiet periods.

Use it to add layered day or night ambience to scenes, choose sound pools, set their timing and mix, and keep music assigned to Foundry playlists.

It fills the gap between ordinary ambient sounds and playlists: a scene can have varied sounds such as a crow or distant dog without playing a constant loop.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00237	$0.06313
Opus 5.5	$0.00095	$0.02525
Sonnet 5.5	$0.00047	$0.01263
Haiku 4.5	$0.00024	$0.00631

Security

Grade A, and why

soundscape-builder 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 2mo ago.

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.

Soundscape builder

The judgment layer over configure-soundscape — house module #6, fvtt-mod-soundscape. The module fills a hole core Foundry has no shape for: AmbientSound placeables are positional single-file loops and Playlists have no concept of silence with variation, so neither can do "a crow, then quiet, then a distant dog." A sound set is a pool of files plus a play style; a scene carries several, stacked and independent.

Per design.md §2.1: the tool owns correctness — the flag schema, the clamps, set resolution, the KEEP+WARN 404 check. This skill owns the judgment — what a place should sound like, how many layers before it turns to mud, the timing, the mix, and the day/night gates. Read _shared/authoring-policy.md; the audio clarification from playlist-builder applies here too — audio has no compendium, so this is asset-driven work.

First: is this even Soundscape's job?

Three different audio systems, three owners. Getting this wrong is the most common failure.

The user wants	Owner	Why
Music — a theme, a track, a boss cue, exploration music, a soundboard	`playlist-builder`	Playlists stay the music system. Soundscape's design.md lists playlist integration as an explicit non-goal — it never touches them.
Ambience: a bed + random one-shots, "make it sound like a place"	this skill	Scene-global pools with randomized silence. Nothing else does it.
A sound coming from one spot on the map — that waterfall, this hearth, the door at the end of the hall	`create-sounds` (AmbientSound placeable)	Soundscape sets are scene-global by design ("no positional interval sounds" — non-goal). A point emitter with a radius is a placeable.

They compose: a crypt can have a Soundscape bed, a positional AmbientSound at the fountain, and a Playlist that starts when the fight does. Build each with its own owner.

Step 0 — Look at the scene before you pick a single sound

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.
