get_logical_port_status

Read-onlyIdempotent

Check the realized state and attachment of up to 50 logical ports on a segment to confirm connectivity or identify unbound ports before deletion.

Instructions

[READ] Check realized state of all ports on a segment (first 50 ports).

Use this after get_segment_port_for_vm has told you which segment a VM sits on, or before delete_segment to see whether ports are still attached. Returns per-port admin_state, attachment (type/id) and realized state: attached, realized_bindings_count, transport_node_ids. NSX does not expose a single UP/DOWN flag per segment port — an attached port with realized bindings on at least one transport node is healthy. Only the first 50 ports are returned.

If bindings are missing everywhere, check get_transport_node_status.

A4.7/5.0
Behavior5/5

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

Annotations already mark this as readOnly, idempotent, and non-destructive, but the description adds important behavioral context beyond them: it explains the returned fields, the 50-port limit, the lack of a single UP/DOWN flag in NSX, and the health criterion of realized bindings on at least one transport node. This meaningfully helps the agent interpret results correctly.

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 front-loaded with the action, then a usage paragraph, a return-value paragraph, a critical NSX semantic clarification, and a fallback pointer. Every sentence earns its place and there is minimal redundancy.

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?

With no output schema, the description carries the burden of explaining return values, and it does so explicitly: admin_state, attachment, realized_bindings_count, transport_node_ids, and the health interpretation. It also flags the 50-port truncation and provides a next-step tool when bindings are missing, making the definition complete for a read-only inspection tool.

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 description coverage is 100%, so the schema already documents both segment_id and target. The description confirms segment_id is the port-inspection scope but adds no additional parameter-level syntax or format details, matching the baseline for fully covered schemas.

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 opens with a specific verb and resource: 'Check realized state of all ports on a segment', and immediately scopes it to the first 50 ports. It distinguishes itself from siblings by explaining when to use it relative to get_segment_port_for_vm and delete_segment, and contrasts with get_transport_node_status for the binding-missing case.

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?

Explicit guidance covers both when to use and when not to use: 'Use this after get_segment_port_for_vm' and 'before delete_segment to see whether ports are still attached.' It also names the alternative path: 'If bindings are missing everywhere, check get_transport_node_status.' This is strong routing behavior for an agent.

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