zpa_get_application_segment

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

The annotations already declare readOnlyHint=true and openWorldHint=false, so the safe read-only nature is covered. The description adds no additional behavioral context beyond that, such as error behavior, required permissions, or the distinction between standard and BA/PRA segments, but it does not contradict the 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 one short, front-loaded sentence with no filler or redundancy. However, it essentially restates the tool name with minimal added information, so it is concise but not exemplary in delivering extra value.

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 tool with no output schema and no behavioral details, the description is too sparse. It does not explain what the returned segment contains, how microtenant_id affects the lookup, or how this getter relates to the many application-segment sibling tools, leaving important context missing.

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 needed to compensate by explaining what segment_id and microtenant_id mean or how they are used, but it provides no parameter information whatsoever. The agent is left entirely to the schema's field titles.

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 uses the specific verb 'Get' plus the resource 'ZPA application segment' and the qualifier 'one', clearly indicating a single-segment retrieval. It distinguishes from the zpa_list_application_segments siblings, but does not explicitly differentiate it from the specialized _ba/_pra application segment getters, so sibling differentiation is incomplete.

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 gives no guidance on when to use this tool instead of nearby alternatives such as zpa_list_application_segments, zpa_get_application_segment_ba, or zpa_get_application_segment_pra. There is no context about prerequisites, scoping, or exclusions.

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