X Post with AI-Generated Image

Generate a Gemini AI image from a text prompt, compress it, and post it as a tweet — all in one command.

Prerequisites

• xurl CLI (X/Twitter auth) — see xurl skill
• GEMINI_API_KEY env var
• nano-banana-pro skill installed (OpenClaw)
• uv Python runner

Setup

export GEMINI_API_KEY="your-gemini-api-key"
export X_CONSUMER_KEY="..."
export X_CONSUMER_SECRET="..."
export X_ACCESS_TOKEN="..."
export X_ACCESS_TOKEN_SECRET="..."

Usage

# Post tweet with AI-generated image
python3 scripts/post_with_image.py \
  --text "Your tweet text here" \
  --prompt "AI image prompt — describe the visual"

# Text-only tweet
python3 scripts/post_with_image.py \
  --text "Your tweet text" \
  --no-image

How it works

1. Calls Gemini image generation with prompt → PNG
2. Compresses + resizes to 1200×675 JPEG (Twitter optimal)
3. Uploads via Twitter media API (OAuth1)
4. Posts tweet with media via xurl

Inputs

| Param | Description | |-------|-------------| | --text | Tweet text (required) | | --prompt | Image generation prompt (optional) | | --no-image | Skip image, post text only |

Output

Tweet posted; media ID and confirmation logged to stdout.
