getSitesDeviceWhiteList

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond that: no mention of pagination behavior (despite page/pageSize), result ordering, or what an empty whitelist looks like, which is all the more relevant since there is no output schema.

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 zero filler. It is efficient, though its brevity is partly the cause of the missing usage and behavioral detail rather than a sign of disciplined compression.

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 read-only, zero-required-parameter list tool with fully documented schema and no output schema, the description is minimally viable. However, it omits pagination semantics and return shape, and gives no hint about how 'device whitelist' differs from the many adjacent allow-list tools, leaving real gaps.

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 page, pageSize, and siteId all fully documented including defaults, bounds, pattern, and the listSites discovery pointer. The description contributes no additional parameter meaning, so the 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 and resource: retrieve the device whitelist for a site. It is clear what the tool returns conceptually, but it does not differentiate itself from nearby defensive/allow-list siblings such as getGridAllowList, getGridBlockList, or getUrlFilterWhitelist, so an agent must infer the distinction from names 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 tool versus alternatives — nothing distinguishes it from the many other whitelist/ACL retrieval tools in the sibling list. The only implied usage is the schema's note that siteId falls back to a configured default, which is not repeated or expanded in the description.

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