get_firmware_update_status

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

With no annotations provided, the description carries the full burden. It discloses that the tool sends a GET request to a specific endpoint, implying read-only behavior, and describes the returned UpdateStatus object. However, it does not explicitly state that there are no side effects, permission requirements, or error conditions, which would improve transparency.

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 concise and well-structured, starting with a clear purpose statement, then explaining the endpoint and return object, and ending with a 'Use case' section. Every sentence adds value without unnecessary verbosity.

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?

Since there is no output schema, the description compensates by explaining the UpdateStatus object and its fields (install and check). It also provides a practical use case. It could add details on error handling or fields' meanings, but for a zero-parameter read tool, it is largely complete.

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 tool has zero parameters, so there is nothing to document. The description appropriately focuses on the return value instead of parameter details, which aligns with the baseline 4 for zero-parameter tools.

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 'Retrieve firmware update state from the Busy Bar device' with a specific verb and resource. It further clarifies the purpose by explaining the endpoint and the returned object, distinguishing it from sibling tools like get_firmware_info and get_update_changelog.

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 'Use case' section explicitly indicates when to use this tool: 'Verify which firmware is running and whether a new update has been detected but not yet installed — useful for maintenance and rollout planning.' It provides clear context but does not mention when not to use it or name alternatives, so it stops short of a 5.

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