Grooming by Element

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds genuinely useful operational context — the POST endpoint, the 10-credit Tier 1 cost, and the required field set — but says nothing about output shape or what the element is computed from.

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?

Every line is short and front-loaded, with no padding, but the brevity results from under-specification rather than economy — the one sentence of prose is too thin for a 13-parameter tool.

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 no explanation, but the description never clarifies the core interpretive premise (whose element, and how it maps to grooming focus/frequency). For a domain-specific pet-astrology endpoint amid hundreds of siblings, that gap is material.

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 must compensate and does not. It merely restates the four required parameters (date, time, latitude, longitude) already enumerated in the schema's required array, leaving at least seven optional parameters (city, name, cosmogram, zodiacType, houseSystem, ayanamsaId, timezoneOffset) explained only by the schema or not 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 phrase 'Grooming focus + frequency by element' does name a resource and a dimension, but 'element' is never defined (pet's natal element? current transit element?) and no sibling such as astroway_pet_birth_chart or astroway_pet_diet_by_sign is distinguished. An agent learns roughly what comes back but not what it is derived from.

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 statement of when to pick this over the many other astroway_pet_* tools, nor any prerequisite or exclusion. The bracketed metadata (group, endpoint, required fields, cost) is procedural, not usage guidance.

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