management_groups_get_all_devices

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

With no annotations and no output schema, the description carries the full behavioral burden, but it only restates the action at a high level. It does not disclose whether the result can be large, whether pagination occurs, what happens to devices not assigned to any group, or any other runtime behavior beyond 'get all devices'.

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 filler: 'Get all devices across all Management Groups.' Every word earns its place and the core action/scope is immediately visible.

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?

For a zero-parameter read operation, the description conveys the essential operation and scope, but it lacks usage guidance and any note about output shape or large-result behavior. Since there is no output schema or annotations to fill those gaps, the description is minimally viable rather than 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 tool has zero parameters, so there is no parameter semantic weight to carry; the description's phrase 'across all Management Groups' clarifies the implicit scope of the operation. Per the 0-parameter baseline, a 4 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 is specific: 'Get all devices across all Management Groups.' It names the verb ('Get'), the resource ('all devices'), and the scope ('across all Management Groups'), which distinguishes it in intent from sibling tools like devices_list or management_groups_get_contents.

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 gives no guidance on when to choose this tool over alternatives such as devices_list, devices_search, or management_groups_get_contents. No condition, exclusion, or prerequisite is stated, so an agent must infer the right context from the name alone.

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