cluster_status

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

readOnlyHint=true already declares the safe-read profile, so the '[READ]' tag adds nothing new. The description does add value by listing the data categories returned (nodes, drives, capacity, buckets, objects), which helps an agent judge the payload, but it says nothing about freshness, pagination, or failure behavior on an unreachable target.

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?

Very short and front-loaded: purpose first, then the single arg with its default. No filler sentences. The redundant '[READ]' prefix is the only wasted token, and it is minor.

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 simple annotated read with one optional param and no output schema, the description covers purpose and the parameter, but leaves the agent guessing how this overlaps with fleet_overview, server_info, node_status, and drive_status, and gives no sense of the return shape despite aggregating five distinct categories.

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%, so the description must compensate for the single 'target' parameter, and it does: it explains the value is a MinIO target name drawn from config and that omission selects the default. That is meaningful beyond the bare string/null schema, though it gives no naming/format example.

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 resource and enumerates exactly what is summarized (nodes, drives, capacity, buckets, objects), so an agent can tell it is an aggregate dashboard read rather than a per-entity query. However, it does not differentiate itself from close siblings like fleet_overview, server_info, or node_status, which also report cluster-level state.

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 prerequisites, and no named alternative among the many sibling status/overview tools. The only instruction is about the target parameter's default, which is parameter semantics, not usage routing.

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