ad_get_sysvol_status

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

No annotations are provided, so the description carries the full burden; the [READ] tag usefully substitutes for readOnlyHint. Beyond that it discloses nothing: it is unclear whether this actively probes a DC (and might be slow or time out), which server/DC scope is defaulted when `server` is null, whether a non-available SYSVOL raises an error or is reported in the result, or what permissions are required.

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 the category and read marker up front; nothing is padded. Brevity here is close to under-specification rather than waste, but the structure itself is clean.

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 (0 required params, no nesting, output schema present so return values need not be explained), but with zero schema coverage and zero annotations the one-line description is not enough: parameter meaning, target scope, and probe/error behavior are all missing.

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?

Schema description coverage is 0% — both parameters carry only bare titles. The description does not mention `server` (presumably the target DC) or `correlation_id` at all, so an agent gets no guidance on defaults, format (hostname vs FQDN), or what correlation_id is for.

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?

States a specific verb and resource: check SYSVOL availability and state. The bracketed tag [Replication, Health & Diagnostics] disambiguates it from the other diagnostics siblings (replication status, DC services, directory health), and no sibling covers SYSVOL, so confusion risk is low. It loses a point only because the description is in Portuguese while the tool name and siblings are English, and it never names the sibling it differs from.

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 when-to-use, when-not-to-use, or alternative named. The category tag implies a diagnostics/replication-health scenario, but an agent must infer that ad_get_directory_health or ad_get_replication_status is a different check. No prerequisites (domain membership, credentials, target DC) are mentioned.

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