firmware_status

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

The readOnlyHint annotation already tells the agent this is a safe read, and the '[READ]' prefix merely restates it. The description adds useful behavior (it reports update availability, not just a version string) and the default-target fallback, but says nothing about auth requirements, rate limits, or return shape for a tool with 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?

One sentence of purpose plus a short Args note — front-loaded, tight, and every line carries information. The '[READ]' tag is mild redundancy against readOnlyHint, but the cost is negligible.

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 single-optional-param read tool with no output schema, the essential call-time information (what it returns conceptually, how to supply or omit target) is present. The only real gap is what the returned payload looks like, which the agent must discover empirically.

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 0% and the schema only carries a bare 'Target' title, so the description carries the full burden — and it does well by explaining that the value is a firewall target name from config and that omission selects the default target. It stops short of giving format examples or listing valid target names.

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 clear resource (firmware/OS version) and outcome (whether updates are available), which is specific enough to distinguish it from status siblings like health_status or interface_status. It does not explicitly name those siblings, but the resource is unambiguous.

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?

Usage is only implied by the tool's nature — an agent can infer it should call this when firmware/OS version or update availability is needed. There is no explicit when/when-not, no prerequisites, and no mention of alternative status tools (health_status, interface_status) for adjacent questions.

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