What it does
Score and enhance image/video generation prompts before spending a credit. Use before calling any image or video generator (Veo, Sora, Kling, Runway, Seedance, Midjourney, Flux, Ideogram, Firefly, etc.) — grades the prompt 0-100, and if it's below 70 (community data shows 84% of prompts are grade F or D), rewrites it using model-specific rules before generating.
The skill document
Dali Creative Intelligence — Proactive Prompt Scoring
You have access to the Dali MCP (dali.getlulu.dev). Use it BEFORE any image or video generation.
The golden rule: never spend a generation credit on an unscored prompt.
When to activate
Any time the user's intent involves generating, creating, rendering, or making an image or video:
- Keywords: generate, create, make, draw, render, animate, illustrate, design, produce
- Media types: image, photo, picture, video, clip, footage, reel, scene, animation
Also activate when a user pastes a raw prompt without asking to score it — score it anyway.
The Flow
Step 1: Detect model
If the user doesn't specify a model, infer from context:
Video:
- Cinematic brand/narrative →
veo3 - UGC, TikTok, social →
seedance - Character animation, facial performance →
kling - VFX, motion-first →
runway - Native audio, 4K →
wan - Cinematic storytelling with camera control →
minimax - Physics-driven (cloth, hair, fluid) →
higgsfield
Image:
- Photorealistic, product photography →
flux - Artistic, editorial, stylized →
midjourney - Typography, logos, text-in-image →
ideogram - IP-safe commercial →
firefly
If still ambiguous: "Which model are you targeting?" and list: veo3, seedance, kling, runway, wan, minimax, higgsfield, flux, midjourney, ideogram, firefly
Step 2: Score immediately
Call score_prompt(prompt=, model=).
Present concisely:
- Grade + score: "Grade C — 58/100"
- 2–3 bullet points of what's missing (from
missingarray) - One-line verdict
Step 3: Decision
| Grade | Score | Action |
|---|---|---|
| A | 90+ | Confirm and generate |
| B | 70–89 | Confirm and generate |
| C | 50–69 | Offer to enhance. If user agrees or doesn't object → enhance |
| D/F | < 50 | Enhance automatically. Show before/after. Use enhanced prompt. |
Step 4: Enhance (when triggered)
Call enhance_prompt(prompt=, model=).
The tool returns a rewrite brief — not a finished prompt. YOU write the enhanced prompt using it.
The brief contains:
native_language_rules— how this model thinksstructure_template— the prompt format to followpriority_fixes— what to add, by weight × gaplength_target— target word countwhat_to_add— specific missing elements
Your job: write the enhanced prompt using these rules. Then call score_prompt on what you wrote to verify improvement.
Show:
- Score delta: "8 → 91 (+83 pts)"
- What changed (key additions from the brief)
- Enhanced prompt in a code block
- Score verification result
Step 5: Generate
Always use the highest-scoring prompt (your enhanced version, not a raw API field).
Output format (keep it tight)
Scored: **Grade F — 8/100** for Veo3
Missing: camera move, motion description, lighting · 8 words only
Verdict: Generic stock footage guaranteed. Enhancing...
Brief applied:
① camera move first: "Slow orbital push"
② physics: "drop falls", "liquid ripples", "glass refracts"
③ lighting: "warm backlight", "rim-lit edges"
Enhanced prompt:
"Slow orbital push around a glass serum bottle on white marble. A single amber drop falls in extreme slow motion, catching warm backlight. Macro: liquid gold ripples outward from impact. Rim-lit edges, soft studio diffusion. Premium, clinical. No text."
Re-scored: **Grade A — 91/100** ✓ Safe to generate.

Rules
- Score FIRST, always — before generating anything
- Don't ask permission to score — just do it
- Do ask permission to enhance if grade is C (auto-enhance D/F)
- Never dump raw JSON — translate to human-readable output
- Lead with grade + missing — not the full dimension breakdown
- You write the enhanced prompt from the brief — don't look for an
enhanced_promptfield in the response - Always re-score your enhanced version to show the delta
Community tools (bonus)
- Grade C or below → call
community_benchmark(prompt, model)to show missing A-grade patterns - "What makes a good [model] prompt?" → call
creative_patterns(model)and summarize top 5 - "Show my history" → call
my_story() - "What models do you support?" → call
list_models()
