Triplicity Rulers

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

Annotations already provide read-only and idempotent hints. Description adds no further behavioral traits, but does not contradict annotations. Adequate given annotations, but description could disclose more about computation or side effects.

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?

Description is very short and front-loaded with the key term, but the example is poorly formed and overall lacks substance. Not wasteful, but too minimal to be effective.

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?

For a tool with 11 parameters, no output schema, and many siblings, the description is critically incomplete. It fails to specify return values, parameter roles, or when to select this tool over similar hellenistic tools.

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 0%, and the description provides no meaning for any of the 11 parameters. The example request body is vague ('...chart...') and does not compensate. Agent has no guidance on parameter semantics.

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?

Description states 'Dorothean triplicity rulers' which identifies the specific resource but lacks a verb indicating the action (e.g., calculates, returns). The grouping and example are present, but purpose is only vaguely implied.

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 on when to use this tool vs alternatives. No mention of prerequisites, context, or exclusions. The example request body is incomplete and does not aid decision-making.

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