start_firmware_upgrade

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

The description prominently discloses a critical behavioral consequence—router reboot and network disconnection—which is especially important given no annotations are provided. However, it omits other behavioral details such as upgrade duration, failure modes, or whether the process is irreversible.

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?

The description is a single, front-loaded sentence with clear action followed by a prominent warning. It is excessively concise with zero filler or redundant information.

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?

Although an output schema exists, the description lacks essential context for a high-stakes operation like firmware upgrade: no prerequisites, no mention of the confirm parameter's role, no expected duration, and no post-conditions. The user is left with only the warning, making the description insufficient for reliable tool invocation.

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?

The only parameter, 'confirm', has no schema description and is not mentioned in the tool description. The warning implies caution but does not explain how the boolean controls the upgrade initiation. At 0% schema coverage, the description fails to compensate for this gap.

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 clearly states the action 'Start firmware upgrade' with a specific verb and resource, and the warning about reboot/network loss distinguishes it from sibling tools like 'upgrade_ap_firmware' or read-only queries. It unambiguously identifies what the tool does.

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 description implies this is for the router's own firmware upgrade via the warning about reboot and network disconnect, but it does not explicitly mention when to use it versus alternative upgrade tools (e.g., AP firmware upgrade) or provide any when-not-to-use guidance. Usage is implied rather than stated.

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