firmware_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 returns a list of firmware components with versions and update availability, and that some printers will return an 'UNSUPPORTED' error. However, it does not mention behavior for cases like no default printer or disconnection, which would add further 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, with two short paragraphs that front-load the main purpose. Every sentence adds value—defining the scope, providing an alternative, describing the output, and noting unsupported backends. No 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?

Given the tool has no parameters, no output schema, and no annotations, the description is self-contained. It adequately explains what the tool does, what it returns, and important exceptions (unsupported backends). The sibling comparison further contextualizes its use. No gaps are evident.

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, and the schema is empty. With a baseline of 4 for no parameters, the description adds value by clarifying that the tool operates on the default/connected printer without needing any input, which is implicit from the schema but explicitly stated.

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 tool's purpose: checking firmware updates on the default/connected printer. It uses specific verbs ('Check') and identifies the resource ('firmware updates on the default/connected printer'). It also distinguishes itself from the sibling tool 'check_firmware_status' by noting the difference in scope (default vs. specific printer by name).

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 explicitly tells when to use this tool (for the default/connected printer) and when to use an alternative ('For fleet setups... use check_firmware_status instead'). It also provides context on unsupported backends (Bambu and Prusa Link), helping the agent decide when the tool might be inappropriate.

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