get_managed_device_by_id

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

No annotations are provided, so the description carries the full burden. 'Get full details' implies a read-only operation, and the 'beta endpoint' note adds useful context. However, it does not disclose any potential caveats (e.g., permissions, deprecation risk), so transparency is adequate but not rich.

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, front-loaded sentence with no redundant words. Every term ('full details', 'single', 'beta endpoint') adds value, making it a model of conciseness.

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?

The tool is simple (one parameter, no nested objects) and has an output schema, so return values need not be described. The description covers the core action and endpoint status. It lacks explicit usage exclusions but is otherwise complete for a straightforward get-by-id operation.

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?

With 0% schema description coverage, the description must compensate. It clarifies that the device is an 'Intune managed device,' adding meaning beyond the bare 'device_id' string. However, it does not explain how to obtain the ID or any format constraints, so it only partially compensates.

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?

Description uses specific verb 'Get full details' with resource 'single Intune managed device', clearly distinguishing from sibling list tools like get_all_managed_devices and get_managed_devices_by_user. The 'by_id' suffix is reinforced, making the tool's scope 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?

The description specifies 'single' device, providing clear context that this is for fetching one device rather than a list. While it doesn't explicitly name alternative tools, the singular scope is explicit and sufficient for an agent to choose this over list-oriented siblings.

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