Training Style

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety. The description adds that it returns 'training style + 3 tips' but provides no further behavioral details (e.g., output format, pagination, or astrological basis). Minimal additional value beyond annotations.

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 extremely concise with no wasted words. The group label aids categorization. However, it is slightly terse and could benefit from a one-sentence elaboration. Example is appropriate but separate.

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 7 parameters, full schema coverage, and annotations, the description is adequate. The group and example clarify that astrology data is used. However, the output format is vaguely described ('3 tips'), and without an output schema, more detail would help. Score 3 for meeting minimum needs.

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%, so parameters are fully documented. The example request body illustrates usage but does not add meaning beyond the schema. Baseline 3 is appropriate.

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 'Preferred training style + 3 tips' clearly states the tool's output. The group label '[Group: Pet Astrology]' and sibling tool names (e.g., pet_personality, pet_communication_style) disambiguate that this is for pets. Purpose is specific and distinct.

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 like pet_personality or pet_communication_style. The description does not mention exclusions, prerequisites, or context. The agent must infer usage solely from the tool name and group.

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