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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description adds meaningful behavioral context: the OData endpoint and batch/ids execution behavior. It does not cover limits or error cases, but the annotation coverage is strong enough for a simple read operation. No contradiction detected.

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 two short, front-loaded sentences conveying the endpoint, the id lookup, $expand usage, and bulk support. Every sentence earns its place without unnecessary filler.

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?

The description is adequate for a basic get-by-id tool but the gap around 'query', '$select', return shape, and any batch-size limitations leaves the agent without enough detail to confidently use more advanced OData behavior. Given the absences of output schema and schema descriptions, more detail would help.

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 0%, so the description needs to compensate. It explains 'id' implicitly and explicitly explains 'ids' and '$expand', but the 'query' and '$select' parameters are not described. The nested query object especially deserves more detail.

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 retrieves an appointment by id: 'Busca um(a) Compromissos/agenda por id (OData /Appointments/{id})'. It also distinguishes itself from list/create siblings by being id-based and from the list appointments endpoint by mentioning bulk support.

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?

It gives direct usage guidance: 'Use $expand para sub-recursos' and 'Bulk support: accepts ids for batched execution.' It does not explicitly name alternatives such as legalone_list_appointments or state when not to use it, so it misses a 5.

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