hosts_get

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It states it's a read operation ('Get'), but doesn't disclose error conditions (e.g., invalid UUID), authentication requirements, rate limits, or what data is returned. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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?

The description is a single, efficient sentence with zero wasted words. It front-loads the core purpose ('Get a specific host') and specifies the key identifier ('by UUID'), making it immediately actionable without unnecessary elaboration.

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?

Given the lack of annotations and output schema, the description is insufficiently complete. It doesn't explain what a 'host' entails in this context, what data is returned, or potential side effects. For a tool that likely returns structured host data, more context is needed to guide effective use.

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?

The description mentions 'by UUID', aligning with the single parameter 'uuid' in the schema. Since schema description coverage is 100% (the parameter is fully documented as 'Host UUID'), the description adds no additional semantic value beyond what the schema provides, meeting the baseline for high 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?

The description clearly states the action ('Get') and resource ('a specific host by UUID'), making the purpose immediately understandable. It distinguishes this from hosts_list (which retrieves multiple hosts) but doesn't explicitly differentiate from other 'get' operations like nodes_get or users_get, which follow the same pattern.

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 guidance is provided on when to use this tool versus alternatives. While the description implies it's for retrieving a single host by UUID, it doesn't mention prerequisites (e.g., needing a valid UUID), when not to use it (e.g., for listing hosts), or how it relates to siblings like hosts_list or hosts_update.

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