Head Line

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true. The description adds no additional behavioral context beyond the annotations, such as what the 'body' parameter should contain or the nature of the response.

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?

The description is very short and to the point, but it lacks critical information. It is concise but under-specified, earning an average score for structure.

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 large set of palmistry sibling tools and the tool's 1-parameter schema, the description is incomplete. It omits details about the required body payload and does not explain what the output represents. The annotations cover safety but not usage context.

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?

The input schema's description for the 'body' parameter merely points to an example in the tool description, but the provided example is empty. The tool description does not explain what fields are required or what the body object should contain, leaving ambiguity.

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 clearly states 'Intellect, mental approach,' which is a precise and conventional interpretation of the head line in palmistry. This distinguishes it from sibling tools like palmistry_heart_line (emotions) and palmistry_life_line (vitality).

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?

No guidance is provided on when to use this tool versus the numerous other palmistry tools or other tools. There is no mention of prerequisites, alternatives, or context for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
