firmware_status

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

No annotations are provided, so the description carries the burden. The '[READ]' marker communicates this is a safe, non-mutating operation, which is useful given the sibling set includes mutating tools (kill_states, reboot, reconfigure). However, it doesn't disclose return format specifics or edge cases (e.g., what happens if no updates are available, or how update availability is determined).

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 extremely compact—two short sentences that convey the purpose and the single parameter. Function-style header '[READ]' front-loads the operational intent. Zero wasted words.

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 read-only query with 1 optional parameter and no output schema, the description is reasonably complete. The '[READ]' marker compensates for missing annotations. It clearly states what's returned (version + update availability). However, given no annotations and no output schema, slightly more detail on return structure or update-status semantics could improve completeness, but the tool is simple enough that current coverage is adequate.

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?

With only 1 optional parameter at 0% schema description coverage, the description adds meaning by explaining 'target' refers to a 'Firewall target name from config; omit for the default.' This clarifies semantics beyond the bare schema, though the actual details are minimal and there's no example or value format guidance.

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 states a specific verb+resource: "Firmware / OS version and whether updates are available." It clearly identifies what information is returned (firmware/OS version + update availability). It distinguishes from sibling tools like health_status, interface_status, and gateway_status which cover different subjects, though it doesn't explicitly name alternatives.

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's no guidance on when to use this tool versus alternatives. The '[READ]' prefix and description indicate it's a read-only informational query, but there's no mention of when firmware status would be relevant (e.g., before upgrades) or when to prefer sibling tools. No exclusions or alternate tool suggestions are given.

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