zscaler_get_toolset_tools

Read-only

Retrieve tools from a specific toolset and check their current availability. Filter results by name or description substring.

Instructions

Drill into a specific toolset to see its tools and whether each one can be called right now. Use after zscaler_list_toolsets has identified the relevant toolset. Each result row has 'available' and (when false) 'unavailable_reason'. Treat 'available: false' as authoritative and report the situation to the user instead of attempting to call the tool. Supports name / description substring filters to narrow the result.

Behavior4/5

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

Annotations declare readOnlyHint=true, and description adds context about result fields ('available', 'unavailable_reason') and behavior on unavailable status. No contradiction; description enriches beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with purpose, each sentence adds value: purpose, usage guidance, result interpretation, filter support. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Output schema exists and description covers key result fields. Tool has 3 params, 1 required. Description adequately covers what the tool returns and how to use filters, but could specify toolset parameter format for completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 0% description coverage. Description mentions substring filters for name_contains and description_contains, adding meaning. However, the required 'toolset' parameter lacks format or example explanation, which would be helpful.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states verb ('drill into') and resource ('specific toolset to see its tools and whether each one can be called right now'), and distinguishes from sibling 'zscaler_list_toolsets' by specifying usage order.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says 'Use after zscaler_list_toolsets has identified the relevant toolset.' Also provides clear instructions on how to handle 'available: false' results (report to user, do not attempt call).

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