Play Style + Toys

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely useful operational context the annotations lack — the POST endpoint, required fields, and the 10-credit Tier 1 cost — but says nothing about what the report contains or how results are scoped.

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?

Very short and the bracketed metadata lines are consistently formatted and easy to scan. Nothing is wasted, though the brevity comes at the cost of substance rather than being earned by it.

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?

An output schema exists so return values need not be described, but for a 13-parameter tool with 23% schema coverage the description leaves the astrological configuration parameters and the report's scope unaddressed. An agent cannot tell which optional parameters matter for this specific pet report.

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 only 23% across 13 parameters, so the description should compensate and does not. Its '[Required: date, time, latitude, longitude]' line merely repeats the schema's required array, and the undocumented optional astrological switches (houseSystem, zodiacType, cosmogram, ayanamsaId) get no explanation at all.

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 play and toy types' essentially restates the title 'Play Style + Toys' and the tool name, without a verb or any indication that this generates a pet-astrology report from birth data. It does not distinguish the tool from close siblings such as astroway_pet_exercise_needs, astroway_pet_training_style, or astroway_pet_temperament.

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 statement of when to use this versus the many other pet tools; the bracket metadata gives required inputs and credit cost but nothing about selection. An agent must infer usage entirely from the name.

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