get_omp_multicast

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' implies a read, but the description does not state that this is read-only and non-destructive, whether results are paginated, or whether both entry types are ever returned together. For a device-scoped query tool with zero annotation coverage, that is a notable gap.

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?

A single front-loaded sentence with no filler; the resource and scope arrive immediately. It is perhaps too terse to earn a 5, but nothing is wasted.

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 simple 3-parameter read tool with full schema coverage and no output schema, the description is minimally adequate. It omits what the response contains and how the two entry types differ, leaving the agent to rely entirely on the schema.

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?

Schema description coverage is 100%, with enums and defaults documented for both 'type' and 'direction', so the baseline is 3. The description only echoes the 'routes or autodiscover' split already present in the schema and adds no further semantics about device_id format or direction meaning.

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?

States a specific verb ('Get') and resource ('OMP multicast routes or multicast auto-discovery entries') scoped to a device, which separates it from the many sibling OMP tools like get_omp_routes and get_omp_peers. It stops short of naming those siblings, so differentiation relies on the word 'multicast' alone.

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?

There is no guidance on when to use this over the closely related get_omp_routes or get_omp_peers, nor on when to pick 'routes' versus 'autodiscover' beyond the bare enumeration. Usage must be inferred entirely from the name and schema.

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