hosts_bulk_disable

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

Annotations declare readOnlyHint=false and destructiveHint=false, so the safety profile is partly covered, but the description adds nothing: it does not say whether disabling is reversible, whether it affects active connections, or how partially invalid UUID lists are handled in a bulk operation.

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 front-loaded sentence with no filler; it is appropriately sized for the operation, though there is essentially nothing beyond the minimum statement.

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 one-parameter mutation with no output schema and a bulk scope, the description is adequate but thin — it omits reversibility, bulk failure semantics, and any permission requirement.

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 carry the param burden. 'By UUIDs' correctly identifies the input as a list of host identifiers, but adds no format, limit, or failure-mode detail beyond the schema's uuid array type.

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?

Names a specific verb ('Disable') and resource ('hosts'), plus the scoping mechanism ('by UUIDs'), so it is immediately distinguishable from hosts_bulk_enable and hosts_bulk_delete. It stops short of explicitly contrasting with those siblings.

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 when-to-use guidance, no mention of the single-host counterpart or the enable/disable pairing. The bulk nature is implied only by the name and the plural 'UUIDs'.

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