dcs_server_registry

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

The [READ] tag merely restates the readOnlyHint=true annotation, adding no new behavioral information. Nothing is said about pagination behavior, the default page size of 100, ordering of results, or what fields a 'registered server' record contains.

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 short sentence with zero padding and the key information front-loaded. Brevity is appropriate here; the shortfall is missing content, not excess wording.

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 low-complexity list tool with no output schema and undocumented parameters, the description should at least state what a returned server record represents and how limit affects results. As written, an agent can call it but cannot reason about its output or scope.

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 parameter (limit) with 0% schema description coverage, so the description carries the full burden of explaining it — yet it never mentions the parameter, its default of 100, or any maximum value. A single clause on paging limits would have resolved this entirely.

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 pairs a specific verb with a specific resource ('List registered servers') and the [READ] prefix signals the operation class. It does not, however, differentiate this from close siblings such as dcs_assets or dcs_status, so an agent cannot tell what a 'registered server' is versus a managed asset.

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 when-to-use guidance, no mention of prerequisites, and no pointer to an alternative sibling tool. The agent must infer from the name alone whether this is the right listing endpoint among ~35 siblings.

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