Happy IMG2 Direct

Generate images with an OpenAI-compatible image provider such as happy/gpt-image-2, with retries and bounded batch concurrency.

Happy IMG2 Direct Skill

Generate real images through an OpenAI-compatible /images/generations endpoint configured in OpenClaw.

Default behavior:

• provider: happy unless OPENCLAW_IMAGE_PROVIDER is set
• model: gpt-image-2 unless OPENCLAW_IMAGE_MODEL is set
• size: 1024x1024
• timeout: 600000ms per image
• output: ~/.openclaw/generated-images/
• no local fake-image fallback
• no built-in message delivery; send or attach files using your normal OpenClaw/channel tools

Single image

python3 skills/happy-img2-direct/scripts/run.py \
  --prompt "A realistic photo of an orange cat sitting by a window, no text, no watermark" \
  --task-name "cat-test" \
  --no-send

Useful flags:

• --prompt required
• --task-name output filename prefix
• --provider provider key in OpenClaw config, default happy
• --model image model, default gpt-image-2
• --size default 1024x1024
• --timeout-ms default 600000
• --output-dir default ~/.openclaw/generated-images
• --max-attempts default 3, maximum 5
• --retry-base-delay, --retry-max-delay, --retry-jitter
• --raw marker for callers that intentionally keep the user prompt unchanged
• --no-send accepted for compatibility; this public skill always leaves delivery to the caller

Successful output is JSON containing ok:true, image_path or output, bytes, model/provider, attempt count, and run directory.

Batch images

python3 skills/happy-img2-direct/scripts/batch_run.py @batch.json

Example:

{
  "batch_name": "article-covers",
  "max_workers": 4,
  "timeout_ms": 600000,
  "send_to_feishu": false,
  "tasks": [
    {"task_name": "cover-1", "prompt": "Realistic shop counter photo, no readable text"},
    {"task_name": "cover-2", "prompt": "Realistic office desk photo, no readable text"}
  ]
}

Batch rules:

• bounded concurrency, current hard maximum 4
• each item has its own task directory and logs
• one failed image does not prevent other images from finishing
• final batch_result.json records success/failure per task
• delivery is disabled in the public version; use OpenClaw/channel tools to send files

Retry behavior

Retries are limited and only used for retryable failures:

• timeout
• upstream failures
• rate limits
• HTTP 408/429/500/502/503/504
• wrapper parse errors

Non-retryable errors, such as invalid requests or auth failures, fail fast with redacted diagnostics.

Safety and publishing notes

This skill intentionally contains no private OpenClaw IDs, no hard-coded user paths, no API keys, and no channel recipient IDs. It reads provider configuration from the local OpenClaw config at runtime.
