get_managed_devices_by_user

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

The description communicates a read operation ('Get') and scoping to a user, but does not disclose any additional behavioral traits such as permissions required, what happens if the user ID is invalid, or whether the result is paginated. Since no annotations are provided, the description carries the full burden and falls short of full transparency.

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, succinct sentence that delivers the core information without fluff. It is appropriately short for a tool with one parameter.

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 has a simple signature with one parameter and an output schema, so a short description is acceptable. However, it could be more complete by mentioning that this operation is read-only or naming alternative tools for all-device or single-device queries, which are nearby siblings.

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 provides a single required parameter user_id with no further description (0% coverage). The description only restates 'a specific userId' and does not clarify the expected format (e.g., GUID, UPN, email) or any constraints, leaving the agent to guess.

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 uses the specific verb 'Get' and identifies the resource 'managed devices' scoped to 'a specific userId'. It clearly distinguishes itself from sibling tools like get_all_managed_devices (no user filter) and get_managed_device_by_id (single device by ID).

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 clearly indicates the intended use case (devices for a specific user) but does not explicitly state when to use an alternative tool. The sibling names suggest a family of device tools, but without explicit guidance, the agent must infer exclusions.

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