Site: List_root_sites

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

Annotations only declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds conceptual scoping ('no parent') but nothing about pagination behavior, result ordering, or what happens with offset/pageSize beyond interacting with an empty root set.

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 tight sentence with the key scoping qualifier front-loaded in parentheses. No filler, nothing to trim.

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 read-only list endpoint with full schema coverage, the description covers the essentials. It would benefit from stating how root-site listing relates to List_sites and whether parent/child hierarchy is returned.

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%, so filter syntax, offset, and pageSize defaults/max are fully documented in the schema. The description adds no parameter-level meaning, so baseline 3 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?

States a specific verb (List) and resource (Brivo root sites) and defines the scope inline as 'top-level sites with no parent'. This implicitly differentiates it from the broader List_sites sibling, but does not name or contrast that sibling explicitly.

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 when-to-use guidance and no mention of the obvious alternative, List_sites, which lists sites generally. The agent must infer from the parenthetical alone whether root-only filtering is desired.

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