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

stable-audio-2.5 scanned grade A with 1 finding 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 today.

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.

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. Open intake → generation-diversity clarification intake before the first POST. 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.
