update_printer_firmware

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

No annotations are provided, so the description carries full burden. It only says 'Start a firmware update' with no details on prerequisites, side effects (e.g., printer restart, downtime), destructive potential, or required permissions. For a potentially destructive action, far more behavioral context is needed.

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 concise: one line for purpose, one line for usage guidance, and a two-line Args block. Every sentence adds value with no repetition or fluff. Front-loaded with key 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 complexity and potential impact of a firmware update tool (no output schema, 2 parameters), the description lacks completeness. It does not explain what happens after the update is started, how to monitor progress, or how to handle errors. An agent needs more context to use this tool safely and effectively.

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%, so the description must compensate. It adds clear, concise descriptions for both parameters: 'Printer to update' for printer_name and 'Specific version to update to (latest if None)' for target_version. This adds meaningful guidance beyond the schema.

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?

Description clearly states the action ('Start a firmware update'), the resource ('on a specific printer by name'), and distinguishes from sibling tools ('fleet-level'). It explicitly mentions version pinning, making the purpose specific and actionable.

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?

Provides explicit when-to-use ('Use this in multi-printer setups') and when-not-to-use ('For single-printer setups, use update_firmware instead'), directly naming an alternative tool. This is exemplary guidance.

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