Health

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

readOnlyHint=true already declares the safety profile, so the description doesn't need to restate it. It does add useful context by naming what is probed (server name, version, AD connectivity), which hints the call touches the domain controller and could fail or be slow, but gives no detail on failure behavior or timing.

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 front-loaded sentence with no filler. It is efficient, though it is short enough that it could have spent a few more words on the domain parameter without becoming bloated.

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?

An output schema exists and readOnlyHint covers safety, so the description needn't explain returns. However, the unexplained 'domain' parameter and the absence of any disambiguation from test_connection/get_domain_info leave real gaps for a diagnostic tool in a crowded sibling set.

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?

There is one optional parameter, 'domain', with 0% schema description coverage, and the description never mentions it. An agent cannot tell from either source what supplying a domain does versus leaving it null.

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 and resource ('Server health check: reports server name, mcpAD/msad version and AD connectivity'), which is clearly a diagnostic read. It doesn't differentiate itself from near-siblings like test_connection or get_domain_info, which an agent could plausibly confuse it with.

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 explicit statement of when to use this tool versus test_connection or get_domain_info, both of which overlap in scope (connectivity checking, domain metadata). Usage is only weakly implied by 'health check'.

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