listUpgradeFirmwares

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 usefully discloses that only *uploaded* firmware eligible for manual upgrade is returned, but it says nothing about result format, ordering, or whether pagination metadata is returned despite exposing page/pageSize.

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 short sentence with the scope qualifier front-loaded and no filler. It is efficient, though its brevity is partly the reason other gaps (pagination, differentiation) exist rather than a sign of completeness.

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 two-parameter, read-only list tool with full schema coverage and annotations, the description covers the essentials. It falls short on how results relate to the sibling firmware tools and on any hint about pagination or volume, which matters at pageSize up to 1000.

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 and pageSize both documented (defaults, ranges) in the schema itself. The description adds no syntax, default, or filtering semantics beyond what the schema already provides, so the baseline of 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?

The description uses a specific verb ('List') plus a qualified resource ('uploaded firmware files available for manual upgrade'), which is much clearer than the bare name. It does not, however, distinguish itself from the similarly named sibling 'listUpgradeOverviewFirmwares' or from 'getFirmwareInfo', so an agent must infer the boundary.

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 phrase 'available for manual upgrade' implies the usage context (choosing a firmware image to push manually), but there is no explicit when-to-use, when-not-to-use, or named alternative. The reader must infer that this is the source list feeding a manual upgrade action.

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