test_host_connection

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it is read-only, what connection protocol it exercises, whether it requires stored credentials, what happens on failure, or whether it has side effects.

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?

It is short, but it is short by virtue of restating the tool name verbatim rather than by being efficient. No sentence earns its place beyond the title, so this is under-specification rather than conciseness.

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?

With no annotations, no output schema, an undocumented required parameter, and an ambiguous sibling (test_host_connection_by_info), the description is not complete enough for an agent to invoke the tool confidently or know what a result means.

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 single parameter 'id' is a bare number with 0% schema description coverage, and the description adds no clarification of what the id refers to (presumably a host id) or what happens if it is invalid. With one undocumented required parameter, the description should compensate but does not.

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 names a specific verb and resource ('Test host connection'), so the basic action is identifiable. However, it is nearly identical to the tool name and gives no differentiation from the sibling test_host_connection_by_info, which clearly tests a host that isn't yet saved. An agent cannot tell which of the two to pick from the description alone.

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 statement of when to use this tool versus alternatives, no prerequisites, and no mention of test_host_connection_by_info for unsaved hosts. Usage must be inferred entirely from the name.

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