zpa_get_application_segment_pra

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

Annotations already declare readOnlyHint=true, so no safety ambiguity exists. The description adds the single-object scope implied by 'Get one,' but it does not describe return format, error behavior, or any other behavioral nuances beyond that.

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 a single, efficient sentence that immediately states the action and resource. There is no filler, redundant wording, or unnecessary detail.

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 simple single-item getter, this description is minimally sufficient: it names the resource and implies retrieval by ID. However, with no output schema and no parameter semantics, the agent gets no information about what the returned segment contains or how microtenant_id should be used.

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%, but the description provides no explanation of segment_id or microtenant_id. The parameter names are somewhat self-explanatory, but the description fails to clarify what these IDs refer to or how microtenant_id affects the lookup.

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 a specific verb+resource construction: "Get one ZPA privileged-remote-access application segment." It clearly identifies both the action and the exact resource type, and the 'privileged-remote-access' qualifier distinguishes it from sibling tools like zpa_get_application_segment and zpa_get_application_segment_ba.

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 phrase 'Get one' implies this tool is for retrieving a single application segment by ID, but there is no explicit guidance about when to use this versus the list variant or the other segment getters. No alternatives or exclusions are stated.

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