hcl_get_device_details

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

The annotations already establish that this is a safe, read-only, idempotent operation. The description adds a cryptic caveat about never claiming guest CLI verification, which is useful context but not clearly explained; it does not describe data source, limitations, or freshness.

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, front-loads the read action, and contains no filler. However, the second clause about guest CLI verification is opaque and may not earn its place without more context.

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?

An output schema exists and annotations cover safety, reducing what the description must explain. Still, the single required parameter is undefined and the purpose is somewhat ambiguous between 'device details' and 'default interfaces', leaving minimum-viable but noticeable gaps.

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 compensate for the required 'model' parameter. It only says 'one installed model', which does not clarify whether 'model' is a device model name, identifier, label, or something else.

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 gives a specific verb ('Read') and resource ('installed model's default interfaces'), but it is ambiguous because the tool name says 'device details' while the description talks about a 'model' and only mentions interfaces. It partially distinguishes from list-style siblings but does not clearly establish that this retrieves device details.

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?

There is no explicit guidance on when to use this tool versus alternatives such as hcl_list_devices, hcl_inspect_project, or hcl_console_exec. The phrase 'one installed model' implies singular retrieval, but no conditions, exclusions, or sibling routing are stated.

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