Stable Audio Prompting is an agent skill from nodetool-ai/nodetool. Prompt Stability's Stable Audio line — the genre/instruments/mood/BPM order its training metadata expects, the TrackType and VocalType tags that separate music, stems and sound effects on Stable Audio 3, matching duration to what you described, which checkpoints guidancescale and step count actually affect, and prompting the inpaint, outpaint and audio-to-audio variants where the surrounding audio outranks the prompt. Use whenever the model id names Stable Audio (fal-ai/stable-audio-25/text-to-audio…
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Music and audio generation. It works with fal and Stable Diffusion. The repository describes itself as: Agent-first Creative Workspace. The licence is AGPL-3.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 339f069. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
stability.aigithub.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Stable Audio Prompting loads about 1.8k tokens when it runs. Until then it costs about 206 tokens; SKILL.md has 928 words of instructions outside code blocks.
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.
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); files beside SKILL.md are not scanned.

.claude/skills/stable-audio-prompting/SKILL.md (or your agent's skills folder).Stable Audio was trained on library-music metadata, so it responds to prompts shaped like library-music metadata: what the genre is, what is playing, how it feels, how fast it goes. Poetic descriptions of a feeling get a generic bed.
Reach the music endpoints with find_model for text_to_music, then
generate_music. The SFX checkpoints and the audio-to-audio, inpaint and
outpaint variants are not in the music catalog — run those nodes with
search_nodes and invoke_node.
Four elements, in this order:
An exciting breakbeat instrumental for a fast-paced game, funky electric guitar chords, steady break drums, smooth electric piano and supporting bass. Fresh, modern and adventurous, 105 BPM.
Two habits that measurably help: vary the vocabulary instead of repeating the same adjective, and reference an era to describe production — "80s gated reverb", "90s grunge distortion" — which encodes a whole chain in three words.
On Stable Audio 3, prefix the type. TrackType: Music, VocalType: Instrumental
is the tag pair for instrumental beds and is worth setting explicitly; the
model otherwise decides whether to bring in a vocal.
Start with TrackType: Instrument, then the instrument, genre, mood and BPM.
This is the path for something that has to sit in a mix rather than be the mix.
Playing technique, recording environment and effects all read: "close-mic'd
upright bass, fingered, small wooden room, light tape saturation".
TrackType: SFX, then three things:
TrackType: SFX. A steel toolbox lid slamming shut on a concrete workshop floor, sharp metallic impact with a short rattling decay, close mic, small room with a hard early reflection.
Then set a short duration. Most effects are under two seconds, and a 30-second request for a door slam gets you a door slam followed by 28 seconds of room.
Match the duration to what you described. The Stable Audio 3 medium checkpoint
goes to 380 seconds, but a prompt describing a loop or a hit produces its best
result when the length fits the description; for a music bed, 60–90 seconds is
the range the guide recommends. Note the field changes name — seconds_total
on 2.5, duration on 3 — and 2.5 defaults to 190 seconds, which is three
minutes of audio nobody asked for.
| Parameter | What it does | Where to sit |
|---|---|---|
num_inference_steps | Sampling steps | The distilled checkpoints are tuned for the default 8 and gain little above it; raise it only on a base checkpoint |
guidance_scale | Prompt adherence | On Stable Audio 3, effective only on base (non-distilled) checkpoints — raising it on a distilled one changes nothing |
negative_prompt | Qualities to avoid (Stable Audio 3 only) | Name the artifact you hear: "clipping", "muddy low end", "vocal chops" |
enable_prompt_expansion | LLM prompt rewrite | Off by default; useful for a three-word prompt, harmful once your prompt is already metadata |
seed | Comparability | Pin it while you change one element at a time |
The base versus distilled split is the one that catches people: on a
distilled Stable Audio 3 checkpoint the two dials most people reach for do
nothing, and the prompt is the whole instrument.
Audio-to-audio seeds generation from a clip, and the dial has two names.
Stable Audio 3 takes init_noise_level (0.9 default): 0.1 keeps the source
close, 1.0 replaces it with noise and generates outright. Stable Audio 2.5
takes strength (0.8 default), which runs the same way — 0 returns the input.
Low keeps melody and rhythm; high strips them and keeps only broad character.
Inpaint and outpaint hold everything outside a masked region and regenerate
inside it — mask_start_seconds / mask_end_seconds on Stable Audio 3,
mask_start / mask_end on 2.5. Here the surrounding audio matters more than
the prompt: a short mask is pulled hard toward its context regardless of what
you wrote, and only a wide mask gives the prompt room. If an inpaint is
ignoring you, widen the mask before rewriting the prompt.
| What went wrong | What to change |
|---|---|
| A generic bed | Rewrite as genre, instruments with character, mood, BPM |
| An unwanted vocal | Add TrackType: Music, VocalType: Instrumental to the prompt |
| The effect is padded with room tone | Cut the duration to the length of the actual event |
| Raising guidance changed nothing | You are on a distilled checkpoint — switch to base or fix the prompt |
| An inpaint ignores the prompt | Widen the masked region |
| Two takes are not comparable | Pin the seed and change one element |
Check the result with analyze_audio, analyze_audio_spectrum and
detect_audio_events rather than listening for it — a missing instrument or a
clipped peak shows up there faster than by ear.
A bed from here is the "track of your own" build in video-audio-continuity:
one clip on its own audio track for the whole runtime, with the generated shots
muted under it. Because the prompt states the BPM, beat-sync-editing starts
with a grid it can predict and then confirms with detect_audio_events on the
file. A TrackType: SFX hit of 1–3 s is what logo-reveal lands a mark on.
motion-graphics carries the timeline ops that lay the clip down.
