se_list

Read-onlyIdempotent

List all Service Engines (AVI data-plane VMs) on the Controller to inventory capacity or locate an SE by name and management IP. Returns status and SE Group for each engine in a single call.

Instructions

[READ] List Service Engines (AVI data-plane VMs) on the Controller.

Returns Name, management IP, status (e.g. OPER_UP) and SE Group per SE, in one call that cannot be paged or filtered. Use to inventory capacity or find an SE's name and IP — use se_health instead for degraded VS health.

TDQS

A4.7/5.0
Behavior4/5

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

Annotations already indicate readOnly, idempotent, and non-destructive behavior. The description adds useful behavioral context by stating the call cannot be paged or filtered and enumerates what it returns, going beyond the annotation signal.

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?

The description is compact, front-loaded with the [READ] intent, and each sentence adds meaningful information. There is no fluff or repetition.

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

Completeness5/5

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

For a zero-parameter read-only list operation with an output schema present, the description covers the purpose, usage, limitations, and alternative. Nothing essential is missing for an agent to invoke it correctly.

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

Parameters4/5

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

The tool takes zero parameters, so the baseline is 4. The description adds no parameter details because none are needed; it instead explains the output fields and constraints.

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?

The description names a specific verb and resource ('List Service Engines ... on the Controller') and states the returned fields. It also differentiates this tool from se_health by noting the health-focused sibling.

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?

It gives explicit use cases ('inventory capacity or find an SE's name and IP') and explicitly directs the agent to se_health for degraded VS health. This provides clear when-to-use and when-not-to-use guidance.

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