list_media_grabbers_devices

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

Annotations already cover the safety profile (readOnlyHint, openWorldHint, idempotentHint, destructiveHint), so the description carries little burden. It adds only the HTTP method/path ('GET /media/grabbers/devices'), which is marginal context beyond the annotations. No contradiction exists between description and annotations.

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 extremely compact—one sentence plus an endpoint line—with no filler. The information is front-loaded and every line earns its place, though it borders on under-specification rather than deliberate 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?

Given the low complexity (zero params, output schema present, full annotations), the description is minimally adequate. However, it lacks any definition of the media grabbers device domain, does not differentiate from sibling list tools, and offers no guidance on expected result scope—gaps an agent would need to resolve elsewhere.

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 and schema description coverage is 100%, so the schema fully documents the input surface. With no parameters to explain, the description adds nothing but nothing is required; the baseline of 4 for zero-parameter tools applies.

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 states a clear verb and resource ('Get all devices') and the endpoint path provides confirmatory scope. However, it does not explain what a 'media grabbers device' is, and the phrasing is generic enough that it does not distinguish this tool from siblings like list_devices or list_media_grabbers without relying on the tool name.

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?

No guidance is provided on when to use this tool versus alternatives such as list_devices, list_media_grabbers, or the closely related list_media_grabbers_devices_discover. There is no stated context, no exclusions, and no indication of what makes this particular list the right choice.

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