# Prompt Copilot — Generic Model Fallback

Load this file when the user wants help writing or improving a prompt for an AI generation model that **doesn't have a dedicated reference file** — Flux, Midjourney, Kling, Sora, Hailuo, Grok Imagine, ElevenLabs, DeepDub, any other image/video/music/TTS model.

If the model is one we have a dedicated file for (Seedance, GPT Image 2, Nano Banana, Veo, Creative Director, Music/Suno), use that file instead — it has model-tuned rules this generic file lacks.

**Kolbo MCP routing:** route by media type:
- Image → `generate_image` / `generate_image_edit`
- Video → `generate_video` / `generate_video_from_image` / `generate_elements` / `generate_first_last_frame` / `generate_video_from_video` / `generate_lipsync`
- Music → `generate_music`
- TTS → `generate_speech` (call `list_voices` first to pick a voice)
- Sound effects → `generate_sound`
- 3D → `generate_3d`

Always call `list_models({ type: "<tool-type>" })` first when the user hasn't named a specific model — see SKILL.md "Core Workflow".

## Your Expertise

- **Image prompts**: composition, lighting, style, artists, camera settings, negative prompts
- **Video prompts**: motion, timing, transitions, camera movements, physics vocabulary
- **Music prompts**: genre, tempo, instruments, mood, era, structure
- **TTS prompts**: tone, pace, emotion, character voice
- **Model-specific knowledge**: Flux, Midjourney, Kling, Seedance, Suno, ElevenLabs (and whatever else `list_models` returns)

## How to Help

1. Ask what the user is trying to create if it's unclear.
2. Use `list_models` to know which models are available for the type they want.
3. Tailor your advice to the specific model's strengths and prompt format. Different models reward different prompt shapes — short-and-clean (Midjourney), narrative-and-detailed (Flux), structural-and-tagged (Suno), cinematography-led (Veo / Kling).
4. Provide a ready-to-use prompt + explain the key choices.
5. Offer variations if helpful.

## Universal Rules

- **Clean prompts only.** No "Output:", "Tips:", "Notes:", "Resolution:", "Dimensions:", or any instructional/meta language inside the prompt body. The prompt is what the model sees — anything not describing the output is noise.
- **Resolution / aspect ratio / duration are MCP-tool params**, not prompt text. Pass them as separate fields on the tool call.
- **Match prompt length to complexity**: focused 2–3 sentences beats a bloated paragraph for simple cases; only go longer when the concept genuinely needs it. Aim for **under ~200 tokens** — long prompts distort.
- **Order matters**: Subject → action/pose → environment → lighting → style (for image); Subject → Action → Camera → Style → Constraints → Audio (for video).
- **Be specific about style** when it matters: "1970s film photography", "watercolor illustration on rough paper", "3D product render with studio softbox lighting" — not vague descriptors like "beautiful" or "high quality".

## Universal Prompt Basics

Concrete sensory language across four axes — pick what fits, don't stuff every prompt with all four:

| Axis | Vocabulary |
|---|---|
| **Subject + setting + style** | "a red fox curled in a snowy pine forest, golden hour, cinematic" |
| **Camera** | Lens (`35mm`, `85mm`, `wide-angle`, `macro`), angle (`low`, `overhead`, `Dutch tilt`, `eye-level`), motion (`dolly in`, `tracking shot`, `whip pan`, `static`) |
| **Lighting** | `rim light`, `neon glow`, `moody backlight`, `soft window light`, `golden hour`, `three-point softbox`, `Rembrandt key from the right` |
| **Style / medium** | `oil painting`, `watercolor`, `photograph`, `anime`, `3D render`, `editorial`, `documentary`, `1970s film` |

### Image-to-image (`generate_image_edit`)

The prompt describes **what changes**, not what's already there.

- ❌ Bad: "a man with brown hair in a leather jacket holding coffee, made into anime"
- ✅ Good: "transform into anime style, vibrant colors, soft cel shading"

The source image is `@image1` — refer to it explicitly when needed: "in `@image1`, replace the sky with sunset; keep everything else identical."

### Image-to-video (`generate_video_from_image`)

The starting frame anchors what the model sees. The prompt describes **motion**, not the static scene.

- ❌ Bad: "a dancer in a red dress in a studio with golden light"
- ✅ Good: "the dancer spins slowly, fabric trails in slow motion; camera dollies in 4s, locked angle, no shake"

Verbs that work: `zooms in`, `dollies left`, `sweeping pan`, `slow push`, `fast whip`, `tilt up`, `crane up`, `tracks alongside`. Subject motion: "the dancer spins", "smoke rises slowly", "leaves drift through frame".

### Positive framing beats negative phrasing

Most models don't expose a `negative_prompt` parameter. Phrase positively:

- ❌ "no blur" → ✅ "tack sharp"
- ❌ "no people" → ✅ "uninhabited landscape"
- ❌ "no cars" → ✅ "empty street"
- ❌ "no waves" → ✅ "calm glassy water"

For models that DO expose `negative_prompt` (some text-to-image variants), keep it short — a 1-line positive description of what to AVOID (`cartoon, animated, low resolution, watermark, text overlay`).

### Aspect ratio guidance (defaults by use case)

| Aspect | Best for |
|---|---|
| `16:9` | Landscape, cinematic, YouTube, broadcast |
| `9:16` | Vertical, social (TikTok / Reels / Shorts / IG Stories) |
| `1:1` | Square, IG feed, profile / icon, marketplace main |
| `4:5` | IG portrait, Pinterest in-feed |
| `2:3` | Pinterest native pin, vertical editorial |
| `3:4` | Portrait, mobile-first |
| `21:9` | Ultrawide cinematic, banner |
| `3:1` / `1:3` | Hero banner, narrow strip |

Model-dependent — always check `supported_aspect_ratios` on the model via `list_models` before passing a value. See SKILL.md "Resolution / Aspect / Duration — validate against caps".

### Safety / content policy

Models reject prompts that trigger NSFW or IP detection. Avoid:

- Real public figures (describe attributes, never name)
- Sexual / explicit content
- Trademarks / branded characters by name (use generic descriptors)
- Copyrighted material verbatim (style references are fine: "in the style of Studio Ghibli")

When a prompt is refused on policy grounds, **do not retry the same prompt**. Rephrase the sensitive part and resubmit. See `workflows/troubleshooting.md` failure-envelope rules.

## Style

Be creative and direct. Provide actual prompt text in a fenced code block, not just advice. Then a 1-line "why this works" note. Reply explanations in the user's language; prompts themselves in English unless the model handles other languages well.

## When to Defer

If during the conversation it becomes clear the user is actually working with one of the models that has a dedicated reference file, switch to that file:

| User mentions / asks for | Switch to |
|---|---|
| Seedance / Seedance 2 / Bytedance video | `models/seedance.md` |
| GPT Image 2 / gpt-image-2 / OpenAI image | `models/gpt-image.md` |
| Nano Banana / Gemini image / Gemini 3 Pro Image | `models/nano-banana.md` |
| Veo / Veo 3 / Veo 3.1 / Google video | `models/veo.md` |
| Multi-scene set / storyboard / "8 angles" / campaign batch | `models/creative-director.md` |
| Suno / song / lyrics / jingle / soundtrack | `models/music.md` |
| HTML presentation / slide deck | `models/html-presentation.md` |
| Landing page / marketing site | `models/landing-page.md` |
| Dashboard / data viz / interactive widget / game | `models/visual-code.md` |
