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

Annotations declare destructiveHint=true and readOnlyHint=false, but the description lumps safe reads (list/status) together with scrub without saying which action is destructive or what scrub does to a live pool. It also omits whether scrub is synchronous, long-running, or permission-gated — context the annotations alone cannot supply for a mixed-mode tool.

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 compact sentence with no filler, which is good, but its brevity comes at the cost of omitting an entire action rather than trimming redundancy. Efficient shape, insufficient 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?

No output schema and a destructive, multi-action tool with a required enum and cluster/node scoping: the description should explain action behavior and return expectations. It leaves the agent unable to predict what a scrub returns or how node omission affects results.

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 coverage is 75%, but the single uncovered element is the required `action` discriminator, whose four enum values carry no descriptions anywhere. The description's parenthetical '(resolves pool names to GUIDs)' only partially clarifies the `pool` parameter, so the most important parameter semantics remain unexplained.

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 specific verbs (list, inspect, scrub) against a specific resource (ZFS storage pools) and distinguishes itself from the sibling dataset/snapshot tools by resource. However, the fourth supported action, disks_usage, is never mentioned, so the stated purpose under-describes the tool.

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?

No indication of when to choose list vs status vs scrub vs disks_usage, and no mention of prerequisites, node scoping, or that scrub is a mutating/long-running operation while the others are reads. An agent must open the enum and guess the intended workflow.

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