panelica_ssh_users_get_v1_ssh_users

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the 'Read-only' line only restates existing metadata. However, the description adds a meaningful auth requirement not present in annotations — 'Required scopes: accounts:read' — and specifies the GET endpoint, giving the agent extra context about access and mechanics.

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 compact at four short lines and front-loads the core purpose: 'List SSH users'. Minor redundancy exists because 'Read-only' and the title restate annotation values, but the overall size is still efficient and scannable.

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?

For a zero-parameter, read-only collection endpoint, the description covers endpoint, category, auth scope, and safety, and the annotations complete the safety profile. It does not describe the response shape or pagination, but for a simple SSH-user listing this is a modest gap rather than a blocking one.

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?

This tool accepts zero parameters and has 100% schema description coverage, so there is no parameter information missing. With no parameters to document, the description appropriately needs no param-level detail.

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 starts with the specific verb 'List' and the exact resource 'SSH users', making the operation immediately clear. It is naturally distinguished from the sibling panelica_ssh_users_get_v1_ssh_users_id, which fetches a single SSH user rather than enumerating all of them.

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 gives useful context such as HTTP method, category, and required scope, but it does not explicitly state when to use this tool versus alternatives. An agent must infer from the verb 'List' that this is for enumerating SSH users rather than fetching, creating, or modifying a specific one.

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