Rudhyar — Lunation Phase

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

Annotations provide readOnlyHint, destructiveHint, and idempotentHint. The description adds the behavioral detail that it performs an '8-phase classification', which is beyond annotations but still lacks specifics on the output or process.

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, but the example request body is incomplete and not informative. While brevity is valued, the lack of substance reduces effectiveness.

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 11 parameters with no descriptions, no output schema, and the tool performing a specific astrological classification, the description is severely incomplete. It fails to explain what the 8 phases are, how to use the parameters, or what the output contains.

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 description coverage is 0% and the description does not explain any of the 11 parameters. The example body with '{...chart:...}' is vague and does not map to actual parameters.

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 states '8-phase lunation classification', which clearly identifies the tool's purpose as classifying lunation phases into 8 phases. The group label 'Modern Psychological' helps distinguish it from other Rudhyar tools.

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?

There is no guidance on when to use this tool versus alternatives. No context is provided about prerequisites, when not to use it, or comparisons with similar tools like 'moon_phase' or other modern_rudhyar_* tools.

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