get_host

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

Annotations are absent, so the description carries full burden. It discloses nothing beyond the core action: it's a read operation (get). It does not mention side effects, authentication needs, rate limits, or error handling (e.g., if host_id not found). This is insufficient for a tool with no annotation support.

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 very short (one line plus arg/return notes). It is front-loaded with the core action. However, it is under-specified and lacks detail, making it less useful than a longer, more informative description would be.

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 tool's simplicity (one param, likely returns a host object) and the presence of an output schema, the description could still be more complete. It omits any mention of error cases, response formats, or unique behavior. In a context with many sibling tools, more context would aid selection.

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 input schema has one parameter, host_id, with no description (0% coverage). The description adds 'Host identifier,' which is essentially a restatement of the parameter name. It provides no additional semantic value, such as format, constraints, or examples.

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 tool's purpose: 'Get host details by ID.' This distinguishes it from sibling tools like list_hosts (which returns all hosts) and get_site_details (different resource). The verb-resource pair 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?

No guidance is provided on when to use this tool vs alternatives. There is no mention of prerequisites, exclusions, or scenarios where another tool would be more appropriate. The description simply states what it does without context.

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