C2.7/5.0
Behavior2/5

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

Annotations already flag destructiveHint=true and idempotentHint=false, so the safety profile is covered. The description adds only the word 'validate', leaving the important behaviors unstated: whether the CT is stopped/restarted, downtime, what happens if migration fails mid-transfer, and how wait/wait_timeout affect the call.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short sentence with no filler and the action front-loaded. It is terse rather than padded; the problem is under-specification, not verbosity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive migration operation with 7 parameters, no output schema, and three undocumented parameters, the description is far too thin. An agent cannot tell how failures are reported or how wait/timeout semantics apply without reading the schema and guessing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 57%, with wait, wait_timeout, and validate_only undocumented anywhere. The description does not explain these or resolve the confusing overlap between the required 'target' and the optional 'node' parameter (documented as 'omit for cluster-wide'), which looks like a genuine ambiguity an agent could get wrong.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb pair (validate and migrate) and resource (Jail) plus the destination scope (another cluster node). It clearly differs from sylve_vm_migrate by naming Jail, though it never explicitly contrasts the two.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no prerequisites (e.g. is the target node required to be drained or in the cluster?), and no mention of when to prefer validate_only or a different sibling. The agent must infer all of this from the parameter names.

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