What This Skill Does

The drawthings skill provides a powerful interface for OpenClaw to interact with the DrawThings application, a high-performance local Stable Diffusion engine optimized for Mac hardware using MLX and CoreML. This skill allows users to trigger text-to-image generation directly through the OpenClaw agent by acting as a client for the DrawThings API. It enables sophisticated image creation workflows including parameter tuning, batch processing, and reproducibility through fixed seeding. Because the generation occurs locally, it leverages your Mac's internal GPU acceleration to provide fast, private, and high-quality visual outputs without needing to upload data to cloud services.

Installation

To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/dustinparsons/drawthings. Once installed, you must define the DRAWTHINGS_URL environment variable, which defaults to http://127.0.0.1:7860. You can configure this easily by running openclaw config set env.DRAWTHINGS_URL "http://127.0.0.1:7860". Ensure the DrawThings application is running on your machine with the API server enabled before attempting to trigger generation tasks.

Use Cases

• Rapid Prototyping: Quickly generate visual concepts and mood boards from descriptive text prompts.
• Batch Asset Creation: Create multiple variations of a game asset or social media banner simultaneously by setting the batch-size parameter.
• Technical Testing: Compare different samplers and guidance scales to find the optimal aesthetic for specific art styles.
• High-Fidelity Rendering: Utilize high step counts and increased resolution settings for final production-ready images.
• Reproducible Design: Use the seed parameter to maintain consistency when refining characters or specific design elements over multiple iterations.

Example Prompts

1. "Generate a cyberpunk cat in a neon city, make sure the resolution is 768x768 and use the DPM++ 2M Karras sampler."
2. "Create 5 variations of a fantasy landscape, with a cfg-scale of 7.5 to ensure it matches my prompt closely."
3. "Generate a portrait photo using the 'quality' preset and set the seed to 42 so I can experiment with variations later."

Tips & Limitations

• Resource Management: Image generation is compute-intensive. If your Mac becomes unresponsive, reduce the resolution or step count.
• Model Compatibility: The skill depends on the models currently loaded within the DrawThings application. Ensure you have your desired checkpoints (e.g., SDXL or SD 1.5) active in the UI.
• Parameter Tuning: Use the 'fast' preset for iterative sketching, as it lowers step counts to 8, while reserving the 'quality' preset for final outputs to avoid wasting compute cycles.
• Privacy: Since this runs locally, your prompts and generated images stay on your machine, making this a highly secure tool for confidential projects.
