get_host

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the HTTP verb and endpoint path ('GET /api/hosts/:uuid'), which confirms the read nature but discloses nothing about lookup behavior such as what happens on a missing UUID.

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 short lines, front-loaded with purpose and zero filler. The endpoint line is arguably redundant with the annotations but no more than one line wasted.

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?

A simple single-parameter read tool with no output schema and annotations covering safety, so the burden is light. Still, the description never says what a 'host' is or what an absent/not-found UUID yields, which an agent would benefit from knowing.

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%, but the single uuid parameter is heavily constrained in the schema itself (uuid format plus regex pattern). The description's 'by UUID' only maps the parameter to the purpose and adds no format or sourcing detail beyond the schema.

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 verb and resource ('Get a host by UUID'), which distinguishes it from the list sibling get_hosts by implying single-item lookup. However, it does not explicitly name get_hosts as the alternative, so an agent must infer the singular/plural distinction.

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 prerequisites, and no mention of alternatives. The only hint is the implicit 'by UUID' lookup semantics, leaving the agent to infer that get_hosts is the plural counterpart.

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