zpa_list_application_segments

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

Annotations already declare readOnlyHint=true, and the description confirms 'read-only'. It adds client-side filtering capability via JMESPath. However, it does not disclose behavioral details like pagination defaults, rate limits, or result limits beyond what annotations provide.

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 sentence with two clauses, efficiently conveying the core purpose and key feature. It is front-loaded and contains no redundant words.

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?

With an output schema present, the description need not detail return values. It covers the listing and filtering aspects. However, it omits default pagination behavior and does not clarify the distinction from the singular get tool, which would enhance completeness.

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?

The input schema has 100% coverage with detailed descriptions for all 6 parameters. The tool description only mentions the query parameter for JMESPath, adding little beyond the schema. Baseline is 3 given high coverage.

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 verb 'List', the resource 'ZPA application segments', and that it supports optional filtering and is read-only. It distinguishes itself from sibling tools like get_zpa_application_segment (singular) and zpa_list_application_segments_ba/pra by being the generic listing tool.

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 mentions JMESPath filtering but does not provide explicit guidance on when to use this tool versus alternatives like get_zpa_application_segment for a single segment or the BA/PRA variants. No 'when not to use' or selection criteria are given.

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