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`
`video-prompting`	Use when crafting video or motion prompts for any generative model — dramaturgy, camera, physics-safe motion, frame anchors, and clip chaining.	`npx skills add PrunaAI/pruna-skills@video-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 `gemini-3.1-flash-tts` 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 (locale, voice, script) before the first POST. Redirect when When NOT to use fits better.

When NOT to use

Use a different skill instead:

Skill	Description	Install
`p-video-avatar`	Use when someone wants a person on camera speaking a script — lip-synced host, spokesperson, or narrated avatar from a portrait photo.	`npx skills add PrunaAI/pruna-skills@p-video-avatar -y`
`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/pruna-skills@music-2.5 -y`
`stable-audio-2.5`	Use when someone wants light instrumental background music — an ambient bed under dialogue or underscore for reels and explainers.	`npx skills add PrunaAI/pruna-skills@stable-audio-2.5 -y`

Environment

export REPLICATE_API_TOKEN=r8_...

Requires ffmpeg / ffprobe when trimming, concatenating scene VO, or mixing with a bed.

HTTP (curl)

curl -s -X POST \
  -H "Authorization: Bearer ${REPLICATE_API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "input": {
      "text": "[warmly] The plush went flying. [short pause] And then it was gone.",
      "voice": "Sulafat",
      "prompt": "Warm storybook narrator, gentle pace, empathetic, no announcer voice.",
      "language_code": "en-US"
    }
  }' \
  "https://api.replicate.com/v1/models/google/gemini-3.1-flash-tts/predictions"

Poll urls.get until status is succeeded; download output (audio URL). Shared client: follow pruna-api (Replicate HTTP in the tool skill).

Before generating

Complete Prerequisites guide reading order.
Confirm text, voice, prompt, and language_code with the user. text, prompt, and inline [tags] must align — same emotional direction (see audio-prompting tts-style-prompting). When listing fields, name REPLICATE_API_TOKEN (Replicate — not PRUNA_API_KEY).
Model notes: combined text + prompt ≤ ~8,000 bytes; output capped ~655s. When TTS feeds p-video as input.audio, keep each line ≤ ~19s (ffprobe) — P-API clips audio at 20s. Common voices: Kore, Aoede, Sulafat, Achird, Charon, Puck, Vindemiatrix — full list on the Replicate readme.

Required input

text (string) — spoken copy; supports inline [tags]. Max ~4,000 bytes.

Common optional fields

voice (default Kore)
prompt — style / director notes (max ~4,000 bytes)
language_code — BCP-47 (default en-US)

Inline tags (examples): [sigh] [laughing] [whispering] [short pause] [medium pause] [long pause] [excitedly].

Typical next steps

Common follow-ons after this skill:

Skill	Description	Install
`p-video`	Use when someone wants a simple short clip from text or images — quick B-roll, drafts, or start/end frame animation. Not when the brief needs cinematic generation, highest quality, tight lip-sync, or imported audio at 1080p.	`npx skills add PrunaAI/pruna-skills@p-video -y`
`p-video-avatar`	Use when someone wants a person on camera speaking a script — lip-synced host, spokesperson, or narrated avatar from a portrait photo.	`npx skills add PrunaAI/pruna-skills@p-video-avatar -y`
`stable-audio-2.5`	Use when someone wants light instrumental background music — an ambient bed under dialogue or underscore for reels and explainers.	`npx skills add PrunaAI/pruna-skills@stable-audio-2.5 -y`
`narrated-multi-scene`	Use when someone wants a multi-part story with voiceover — episodic B-roll, chaptered promo, or several linked video scenes without on-camera dialogue.	`npx skills add PrunaAI/pruna-skills@narrated-multi-scene -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`
