calculate_pet_vaccination_schedule

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

No annotations are provided, so the description must disclose behavioral traits like idempotency and side effects. It does not state whether this is a read-only or mutating operation. The mention of a missing input parameter further reduces clarity.

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 brief with two sentences. The first sentence states the purpose, the second gives usage context. It could be more concise by not repeating inputs already in schema, but overall efficient.

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?

With no annotations and output schema not shown, the description mentions return values (upcoming dates and vaccines) but fails to address edge cases like invalid age ranges or future birth dates. The missing 'last vaccine date' parameter creates a significant gap.

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%, but the description adds incorrect parameter info by mentioning 'last vaccine date' which is not in the schema. It adds no meaningful meaning beyond what the schema already provides for pet_type and birth_date.

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 verb 'Generate' and resource 'vaccination schedule for puppy or kitten'. It distinguishes from sibling pet calculators. However, it incorrectly includes 'last vaccine date' as an input, which is not in the schema, causing confusion.

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 suggests use for 'pet care planning' and directs to list_bundles for related calculators. It does not provide explicit when-to-use or when-not-to-use guidance relative to siblings or prerequisites.

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