What its author says it does

Copied from the file, not written here

Use when someone wants light instrumental background music — an ambient bed under dialogue or underscore for reels and explainers.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Prerequisites

Install and load these skills before generating (skip if already in context via @pruna):

Skill	Description	Install
`generation-diversity`	Use when writing any generative prompt — ritual seed, explicit structure, scenario axes, and quality gates before paid API calls.	`npx skills add PrunaAI/pruna-skills@generation-diversity -y`
`audio-prompting`	Use when crafting TTS, music, or bed prompts for any generative audio model — director style, song structure, and post-production layering.	`npx skills add PrunaAI/pruna-skills@audio-prompting -y`
`pruna-api`	Use before any Pruna or Replicate HTTP call — credentials, upload/poll/download, parallel batches, and agent safety.	`npx skills add PrunaAI/pruna-skills@pruna-api -y`

Or install the full suite once: npx skills add PrunaAI/pruna-skills@pruna -y

Follow each skill's Before generating / craft sections — do not restate guide content here.

Agent habit

In the first reply, name `stable-audio-2.5` in backticks, confirm REPLICATE_API_TOKEN (or stop with signup links from pruna-api), then ask for required inputs. Redirect when When NOT to use fits better.

When NOT to use

Use a different skill instead:

Skill	Description	Install
`music-2.5`	Use when someone wants an original AI song with vocals — sung lyrics, a style prompt track, or source audio for a music video.	`npx skills add PrunaAI/[email protected] -y`
`gemini-3.1-flash-tts`	Use when someone needs spoken narration or voiceover — explainer tracks, documentary lines, or voice to pair with generated video.	`npx skills add PrunaAI/[email protected] -y`

Environment

export REPLICATE_API_TOKEN=r8_...

Requires ffmpeg and ffprobe on PATH for the mix step.

HTTP (curl)

curl -s -X POST \
  -H "Authorization: Bearer ${REPLICATE_API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "input": {
      "prompt": "Instrumental light electronic pop bed, soft groove and mellow synth pads, calm positive tech atmosphere, understated background music, no vocals, 94 BPM",
      "duration": 90,
      "steps": 8,
      "cfg_scale": 1
    }
  }' \

Before generating

Complete Prerequisites guide reading order — bed prompt craft: audio-prompting Worked examples (instrumental bed).
Confirm prompt, duration (match or slightly exceed reel length), and mix volume (~0.08–0.15 under VO). When listing fields, name REPLICATE_API_TOKEN (Replicate — not PRUNA_API_KEY).
Model notes: lead with Instrumental and no vocals. Duration 1–190s. Prefer understated beds (BPM ~88–98 for tech launch reels) so music does not compete with dialogue.

Required input

prompt (string)

Common optional fields

duration — seconds, 1–190
steps — 4–8 (default 8)
cfg_scale — 1–25 (default 1)
seed — optional integer

Typical next steps

Common follow-ons after this skill:

Skill	Description	Install
`gemini-3.1-flash-tts`	Use when someone needs spoken narration or voiceover — explainer tracks, documentary lines, or voice to pair with generated video.	`npx skills add PrunaAI/[email protected] -y`
`visual-transition-reel`	Use when someone wants a montage with transitions between shots — action-sequence reel or multi-scene piece where narration is optional.	`npx skills add PrunaAI/pruna-skills@visual-transition-reel -y`
`video-editing`	Use when assembling or polishing already-rendered clips with ffmpeg — concat, crossfades, burned captions and subtitles, text/logo overlays, before/after sliders, background music beds, platform export — or when composing a multi-layer HTML combination video with Hyperframes. Not for AI video generation, prompt craft, or model-based video edits.	`npx skills add PrunaAI/pruna-skills@video-editing -y`
