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

With no annotations, the description carries the full burden and does disclose important behavior: fixed allowlisted operations, JSON GET only, no URL/header/tenant overrides, no binary downloads, and no writes. It still omits error behavior, auth requirements, and details about what the allowlist contains, so it is strong but not complete.

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 very compact and contains no filler, with each fragment carrying a constraint. It is slightly too terse and begins with restrictions rather than the tool's primary action, but the structure is 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?

For a four-parameter tool with no annotations and no schema descriptions, the definition is missing essential semantics for the required operation_key and company_name parameters and for path_parameters. The output schema exists, so return values need not be explained, but invocation details remain incomplete.

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 must compensate for four undocumented parameters. It only adds 'Query beans are FLAT' for the query parameter and does not explain operation_key, company_name, or path_parameters.

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 the operation is a 'Fixed allowlisted JSON GET only', which implies a read, but it does not explicitly say it reads/executes a named Nextesy operation. It also does not distinguish this tool from siblings such as describe_nextesy_operation, preview_nextesy_operation, or find_nextesy_operations.

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 useful exclusions ('No URLs/headers/tenant overrides, binary downloads or writes') that define when this tool must not be used. However, it does not explain when to choose it over the related describe, preview, or find tools, so guidance is only implied.

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