calculate_dog_pregnancy

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

No annotations are provided, so the description must disclose behavior. It states the tool returns a due date window and milestone dates, which is informative. However, it does not clarify that the tool is a pure computation (no data mutation) or mention any side effects, leaving some ambiguity.

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 concise with three sentences, each adding value: purpose, usage, inputs/outputs, and a cross-reference. No wasted words, and it is front-loaded with essential information.

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 simple calculator tool with one parameter and an existing output schema, the description covers the key aspects (gestation period, output, target audience). It could mention edge cases or format examples, but overall it is sufficiently complete.

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 100% (the only parameter has a description). The description repeats 'Inputs: mating date' but adds no additional semantic detail beyond the schema. According to rules, baseline is 3, and the description does not exceed it.

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 clearly states the tool computes dog due date from mating date with a specified gestation of 63 days, which is a specific verb-resource combination. However, it does not explicitly differentiate from sibling calculators like 'calculate_cat_pregnancy' or 'calculate_breeding_due_date', though the name and reference to 'animaux' calculators provide some context.

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?

The description mentions 'Use for breeders' as a usage context but does not provide explicit when-to-use or when-not-to-use guidance. It references 'list_bundles' for related calculators but stops short of specifying alternatives or exclusion criteria.

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