iap_test_connection

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

No annotations are supplied, so the description carries the behavioral disclosure burden. It does state the operation is a login plus a 'safe' (read-only) version check, which signals non-destructive behavior and authentication. However, it leaves vague what 'safe' means, what credentials or session assumptions exist, and what happens on connection failure.

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?

One concise sentence with no filler; 'safe' and 'log in' are meaningful signals. It front-loads the action and avoids restating the tool name.

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?

The tool is simple and has an output schema, so return values need not be described in detail. However, the missing parameter semantics and lack of usage guidance leave clear gaps for a two-parameter tool with no annotations, making the description adequate but not complete.

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 input schema has 0% description coverage and the description never mentions iap_ip_addr or cluster_name. The property names are somewhat suggestive, but the description does not explain whether one or both are required, how the target is selected, or how the null defaults behave.

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 uses a concrete action ('Log in ... run a safe version check') with a clear target (the Instant AP), so the agent can tell it is a connectivity/authentication probe rather than a data fetch. It does not explicitly distinguish this from sibling iap_get_version, which also deals with version information, so it stops short of full differentiation.

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?

No guidance is provided on when to use this tool instead of the many sibling getters. It neither states that it should be used as a pre-flight connection check nor lists alternatives such as iap_get_version, so the agent must infer usage largely from the tool name.

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