Send a one-shot prompt to xAI Grok and receive its reply. Designed for stateless, single-turn queries.
Send a one-shot prompt to xAI Grok and return its reply. Stateless — for multi-turn use grok_consult.
| Name | Required | Description | Default |
|---|---|---|---|
| prompt | Yes | The prompt to send to Grok. | |
| model | No | Override default Grok model (e.g. 'grok-4'). | |
| timeout | No | Per-call timeout in seconds. Defaults to 300. Raise for long grok-4 reasoning. |

+}v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but the description fully covers behavioral traits: stateless, one-shot, returns reply. No contradictions; the description is sufficient for understanding the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no waste. Every part is necessary and informative, front-loaded with the core purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple stateless nature, 3 parameters, and no output schema, the description covers all needed context: purpose, statelessness, usage guidance, and parameter details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, baseline 3. The description adds value by explaining model parameter overrides and timeout details ('Defaults to 300. Raise for long grok-4 reasoning'), going beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Send a one-shot prompt to xAI Grok and return its reply', clearly identifying the action and resource. It distinguishes from sibling tools by noting 'Stateless — for multi-turn use grok_consult'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear guidance: use for one-shot stateless queries, and directs to grok_consult for multi-turn interactions, naming the specific alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
