List Weaviate database users

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the read-only safety profile is known without the description. The description adds nothing beyond that – no note on scope (all users vs per-cluster), pagination, or whether the default namespace is included – so it fails to earn credit even against the lower annotated bar.

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?

The single short sentence is front-loaded and free of waste, but its brevity comes from under-specification rather than disciplined editing. There is no structure to speak of because there is essentially no content.

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 two-parameter list tool with no output schema, the description should at least clarify listing scope and the meaning of the optional namespace; it does neither. An agent can guess the intent from the name but cannot confirm behavior from the definition.

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% overall: the required `cluster` parameter has only a regex pattern and no explanatory text anywhere, and `namespace` is documented only indirectly through the $defs entry. The description supplies none of the missing semantics, such as what a cluster identifier looks like or how omitting `namespace` is interpreted.

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?

Tautological: description restates name/title.

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 the alternative weaviate_user_get for fetching a single user, and no note about whether a namespace is required to scope the listing or whether it defaults to something. Nothing routes the agent between this and its siblings.

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