## 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` |

| `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 `` `whisperx` `` 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/pruna-skills@music-2.5 -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/pruna-skills@gemini-3.1-flash-tts -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` |

## Environment

```bash

export REPLICATE_API_TOKEN=r8_...

```

## HTTP / pipeline

Prefer the repo helpers (they upload local audio and write JSON + SRT):

```bash

# Agent: follow phase table in this SKILL.md \

--song output/my-mv/song.mp3 \

--out output/my-mv/whisperx_transcript.json \

--initial-prompt "First few lyric lines help recognition"

# Agent: follow phase table in this SKILL.md \

--cuts output/my-mv/cut_manifest.json \

--transcript output/my-mv/whisperx_transcript.json \

--song output/my-mv/song.mp3

```

In a music-video workflow, run this skill during the **align** phase — see `music-video`.

## Before generating

1. Complete Prerequisites guide reading order.

2. Confirm **`audio_file`** (HTTPS URL — helpers upload local files), **`language`**, and **`align_output: true`** for **word-level** cut alignment. When listing inputs, name **`REPLICATE_API_TOKEN`** (Replicate — not `PRUNA_API_KEY`).

3. **Model notes:** set **`initial_prompt`** to the first lyric lines for better rap/sung recognition. Optional **`diarization`** for multi-voice battles.

## Required input

- `audio_file` (HTTPS URL)

## Common optional fields

- `language` — ISO code, e.g. `en`

- `align_output` — **`true`** for word-level timestamps (required for cut alignment)

- `initial_prompt` — first lyric lines

- `diarization` — speaker labels
