getGridAutoCheckUpgrade

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 without description help. The description adds that results are a plan/check listing rather than live device state, which is mildly useful, but says nothing about pagination behavior, result volume, or whether the list is grid-wide — notable gaps for a paginated list tool.

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?

Two sentences, front-loaded with the core action and scope, with no redundant phrasing. The trailing 'Useful for...' sentence carries real routing value, though it could have been spent on sibling differentiation instead.

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 is adequate but thin. It omits pagination semantics and any hint of the return shape (no output schema exists), and it does not clarify the 'Grid' scope implied by the name, which matters given several overlapping upgrade tools.

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% and both parameters (page, pageSize) are documented with defaults and ranges in the schema itself. The description adds no meaning beyond the schema — it does not even mention that results are paged — 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 gives a specific verb and resource ('Get the auto-check upgrade plan list') and states the scope ('scheduled firmware upgrade checks across devices'). It is clear what the tool returns, but it never distinguishes itself from closely related siblings such as getFirmwareUpgradePlan or getUpgradeLogs, leaving the agent to guess which upgrade view to pick.

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 second sentence supplies use cases ('auditing upgrade schedules', 'identifying devices due for automatic firmware updates'), which is better than nothing. However, there is no explicit when-not guidance and no reference to the alternative upgrade-plan tools in the sibling set, so selection between them is left to inference.

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