nexterm_list_identities

Read-onlyIdempotent

Lists accessible Nexterm identity metadata without returning credential material, so you can review available identities before managing server entries.

Instructions

List accessible Nexterm identity metadata. Credential material is never returned.

A3.6/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, open-world behaviour, so the bar is lowered. The description still adds real value by disclosing that credential material is never returned, which tells the agent this tool is safe for inspection without secret exposure. It stops short of describing result shape or pagination.

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?

Two short sentences, zero filler. The purpose is front-loaded and the security caveat follows as the single most decision-relevant detail.

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

Completeness3/5

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

With no output schema present, the description carries more burden for explaining return content, yet 'identity metadata' is left vague – the agent cannot tell what fields (usernames, key fingerprints, labels) come back. For a zero-parameter list tool the definition is adequate but thin on what the caller will receive.

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; there are no parameter semantics for the description to explain and it correctly says nothing misleading about inputs.

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

Purpose4/5

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

Uses a specific verb ('List') and resource ('Nexterm identity metadata') with a scope qualifier ('accessible'). An agent immediately knows this is a read-only enumeration of identities, though the description does not contrast it with any sibling (there is no other identity tool in the sibling list, so the differentiation need is low).

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

Usage Guidelines2/5

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

No statement of when to call this versus alternatives, and no mention of prerequisites such as which permissions determine 'accessible'. The term 'accessible' hints at permission scoping but the agent must infer it.

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