Tools

Functions exposed to the LLM to take actions

NameDescription
ask_grokB

Ask Grok a question and get a response. Default model: grok-4.3. Supports system prompts and sampling parameters (temperature, max_tokens, top_p). Run list_models to see all available model options.

generate_imageB

Generate an image using Grok's Aurora image model and save it to a local file. Default model: grok-imagine-image-quality. Use the optional 'model' parameter to use a different image model.

list_modelsA

List all xAI models available to your account, including their IDs and capabilities. Use this to discover which models you can pass to ask_grok or generate_image. You can also filter by type: 'chat' for language models or 'image' for image generation.

grok_consensusA

Runs a full iterative Consensus Validation Protocol (CVP) between Claude and Grok. Returns a structured final summary. Default 3-5 rounds. Supports custom round count via the 'rounds' argument.

grok_validateA

Runs a rigorous Validation Protocol on any artifact (code, plan, research, prompt, PR, architecture, etc.). Produces a scored scorecard, identifies weaknesses, and returns an improved version. Use this as your mandatory quality gate before shipping complex work. Default model: grok-4.3.
