printer_ams

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

No annotations are provided, so the description carries the full burden of explaining behavior. It lists observable fields but does not state that the tool reads current state, whether it is safe/read-only, what the response shape is, or whether any side effects occur. This is a meaningful gap for a tool with no output schema.

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 terse, with no filler or redundant phrasing, and the resource name is front-loaded. However, it is a fragment rather than a complete sentence, so it sacrifices a little clarity for brevity.

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 zero-parameter tool, the listed fields provide reasonable situational context, but the lack of an explicit verb, output schema, or relationship to printer_status leaves some ambiguity about what invoking the tool actually returns. It is minimally viable but not fully 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 and the schema is empty, so there are no parameter semantics to explain. The description adds enough context by indicating that the tool concerns AMS/external spool trays and their attributes, matching the baseline for a no-parameter tool.

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 identifies a specific resource — AMS / external spool trays — and names concrete data fields: type, color, empty, active tray. It is not a tautology, but it lacks an explicit verb such as 'get' or 'return', and does not directly contrast with printer_status.

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 is no explicit statement about when to use this tool instead of siblings like printer_status or printer_doctor. The intended use is only implied by the resource name and listed fields, with no exclusions or alternative routing guidance.

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