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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive. The description adds that the tool reads prescriptions and lists models, and supports bulk operations. This provides mild behavioral context beyond annotations, but nothing deep like auth needs or side effects. No contradiction with 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 relatively short and includes the key action and exclusions early. However, it redundantly lists actions and then says '[Flattened action: list_models]', which could be streamlined. Still, it is not overly verbose.

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 there is no output schema and 8 undocumented parameters, the description fails to explain what the tool returns or how to use most parameters. It also does not describe the format of the list or templates. This is inadequate for correct invocation.

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 0% so description must compensate. It only mentions patient_ids and prescription_ids for bulk, ignoring skip, take, search, account, patient_id, prescription_id. Most parameters are unexplained, making it hard for an agent to know how to use them correctly.

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 states it reads supplement/herbal medicine prescriptions and lists models, and explicitly distinguishes from meal plans. However, it lists multiple actions (list, get, list_models) which may confuse the tool's specific purpose given the name 'list_models'. That said, it is clear enough that the tool handles listing of template models.

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 provides a clear exclusion (not meal plans, use dietbox_meal_plan) and mentions bulk support for batched execution. However, it does not explicitly guide when to use this tool over the sibling tools dietbox_prescription_list or dietbox_prescription_get, which have overlapping purposes. Usage context is implied but not fully clarified.

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