Avatar Inspired Poster Generator

What it does

This prompt instructs an AI to act as an image director and design a cinematic, highly detailed movie-poster-style artwork inspired by the Avatar film universe, using provided inputs for title, characters, theme, visual elements, color palette, and optional tagline. The expected outcome is a cohesive, official-looking promotional poster with epic composition, glowing bioluminescent atmosphere, and clear typography placement for the title and tagline, all aligned to the specified mood and palette.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Models and options

This skill's modality is: image.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "image".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required text inputs:
  • Tagline
  • Theme_Mood
  • Poster_Title
  • Color_Palette
  • Main_Characters
  • Visual_Elements
• Optional: model and options.
  • Present the human with the default model gpt-image-1 and its available options. Look up gpt-image-1 in the betterprompt resources output (filtered to modality "image") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {"quality":"high"}.
  • If the human does not specify, defaults are used: model gpt-image-1, options {"quality":"high"}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use avatar-inspired-poster-generator).

Command form:

betterprompt generate avatar-inspired-poster-generator \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gpt-image-1.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"quality":"high"}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate avatar-inspired-poster-generator \
  --input Tagline=<value> \
  --input Theme_Mood=<value> \
  --input Poster_Title=<value> \
  --input Color_Palette=<value> \
  --input Main_Characters=<value> \
  --input Visual_Elements=<value> \
  --model gpt-image-1 \
  --options '{"quality":"high"}'
