get_printer

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

No annotations are provided, so the description carries the burden. It does disclose what the response contains (mods, assigned filament), but it does not mention error handling, read-only implications, or permission requirements. The name implies a read operation, but the description adds limited behavioral context beyond that.

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 sentence for purpose and one for the parameter. No filler or redundancy. It is appropriately front-loaded and every sentence earns its place.

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 simple tool (one parameter) and the presence of an output schema, the description is largely complete. It explains the purpose and parameter sufficiently. A slight improvement would be referencing list_printers for obtaining printer_id, but this is not essential for correct invocation.

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 input schema has no parameter descriptions (0% coverage), so the description must compensate. It defines 'printer_id' as 'The ID of the printer', adding semantic meaning that the schema alone lacks. This is helpful, though it does not specify how to obtain the ID (e.g., via list_printers).

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 with a specific verb ('Get') and resource ('full details on a specific printer'), and even specifies the details include mods and assigned filament. This distinguishes it from siblings like 'list_printers' (listing all) and 'update_printer' (modifying).

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 context is clear: use this tool when needing full details for a single printer. The modifier 'specific' implies it is not for listing all printers, but no explicit alternative is named. This provides good situational guidance without exclusions.

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