verify_cpanel_connection

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

With no annotations, the description carries the full burden; it does disclose that this performs an actual live round-trip and validates credentials, which tells the agent it is not a cached/static read. However, it says nothing about side effects, rate limits, or what a failure looks like (auth error versus unreachable host), which matters for a network-dependent check.

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?

A single short sentence, front-loaded with the action and free of filler. Slight redundancy between 'Test' and 'verify' but it costs almost nothing.

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 diagnostic tool with no annotations and no output schema, the description covers what it does but not how to interpret the result or where it fits in an auth workflow. An agent could call it, but would not know whether a success implies a session, or how it differs from login_cpanel.

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?

The tool takes zero parameters, so the baseline is 4; there is nothing the schema could document that the description omits. No additional parameter meaning is needed or expected.

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 states a specific verb pair ('Test and verify') and resource ('the live connection and credentials to the cPanel server'), so it is clear this is a connectivity/credential check rather than an action on server content. It does not explicitly distinguish itself from other auth-adjacent siblings such as login_cpanel or get_login_status, which keeps it from a 5.

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?

There is no guidance on when to call this versus login_cpanel, get_login_status, or get_ssh_connection_info, all of which sit in similar 'check my access' territory. The word 'live' hints at a real round-trip for diagnostics, but the agent is left to infer that this is a pre-flight/diagnostic call rather than part of the login flow.

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