Create ZFS pool

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

Discloses destructive behavior and disk wiping, which goes beyond the destructiveHint annotation. Provides clear behavioral context for agent decision-making.

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?

Two sentences, front-loaded with purpose, immediately followed by critical warning. No redundancy or unnecessary words.

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?

Adequate for a destructive creation tool but lacks description of return value or behavior beyond creation. Missing parameter details reduce completeness for parameter-heavy tool.

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 only 43% (3 of 7 params have descriptions). Description adds no extra parameter information, leaving ashift, raidlevel, compression, and node undocumented. Fails to compensate for low schema coverage.

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?

Description clearly states it creates a ZFS pool across disks. Distinguishes from sibling create_pool by name but lacks explicit differentiation. However, verb+resource is specific and unambiguous.

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?

Includes destructive warning and user confirmation instruction, but no guidance on when to use this tool vs alternatives like create_pool or init_node_disk. Context for when not to use is missing.

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