get_device

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

With no annotations present, the description carries full burden. It states 'get full details' but does not clarify what 'full details' includes (e.g., specific properties, response structure) or any edge cases (e.g., device not found). It lacks important behavioral context such as whether the operation is read-only.

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, concise sentence that efficiently conveys the tool's purpose without any unnecessary words or formatting issues.

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 has only one parameter and no output schema, the description adequately conveys the core purpose. However, it could be improved by noting the response behavior (e.g., returns all device properties) or handling of non-existent IDs. For a simple retrieval tool, it is nearly complete.

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 schema already provides a clear description for the 'id' parameter ('Device object ID (GUID) from Azure AD / Entra ID'). The description adds 'by its object ID', which reinforces but does not add new meaning beyond the schema coverage of 100%. Baseline 3 is appropriate.

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 verb 'Get', the resource 'full details of a specific Entra ID device', and the method 'by its object ID'. It effectively distinguishes from sibling tools like list_devices (which returns multiple) and get_computer (different resource).

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?

The description implies usage for retrieving a single device by ID but does not explicitly state when to use this tool over alternatives (e.g., get_computer for computer objects) or mention any exclusions. Context can be inferred from sibling names, but no direct guidance is provided.

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