Coze Image Generation

Generate one or more images from a prompt using Coze.

This skill runs as a Node CLI wrapper around the backend SDK. Do not use the SDK from client-side code.

Quick start

node {skillDir}/scripts/gen.mjs --prompt "A futuristic city at sunset"
node {skillDir}/scripts/gen.mjs --prompt "A serene mountain landscape" --count 2 --size 4K
node {skillDir}/scripts/gen.mjs --prompt "A hero's journey through magical lands" --sequential --max-sequential 5
node {skillDir}/scripts/gen.mjs --prompt "Transform into anime style" --image "https://example.com/input.jpg"
node {skillDir}/scripts/gen.mjs --prompt "A modern office workspace" --response-format url

Options

• --prompt <text> required prompt text
• --count <n> number of independent generation requests, default 1
• --size <size> image size: 2K, 4K, or WIDTHxHEIGHT, default 2K
• --image <url> reference image URL; repeat the flag to pass multiple images
• --response-format <format> only supports url
• --watermark <true|false> whether to keep watermark
• --optimize-prompt-mode <mode> prompt optimization mode passed through to the SDK
• --sequential enable sequential image generation
• --max-sequential <n> max sequential frames, default 15
• --header <key:value> custom HTTP header; repeatable, alias -H

Notes

• The skill runtime requires plugins.entries.coze-openclaw-plugin.config.apiKey.
• {skillDir} means the directory containing this SKILL.md.
• Successful runs print generated URLs directly.
• Printed image URLs must be kept exactly intact, complete, and accurate. All URL parameters must be preserved without truncation, rewriting, omission, or reordering; in particular, parameters inside the query string such as sign must not be dropped, otherwise the image may be inaccessible.
• Unless the user explicitly asks to download the URL content, only return the complete URL link to the user.
• This skill does not expose base64 output.
