printer_status

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

No annotations exist, so description carries full burden. It discloses supported brands and sentinel value handling but omits critical behaviors: required SNMP version/community, read-only nature, error handling (unreachable host), or potential side effects.

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?

Description is concise with three sentences, front-loading main purpose and supported brands. No redundant information, though could benefit from structured details about parameters.

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?

Covers reported components (supplies, trays, bins, alerts) and sentinel value handling, which aids understanding. However, lacks behavioral context (e.g., authentication, timeout) and does not describe return format despite missing output schema.

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 has one required parameter 'host' with no description coverage (0%). The tool description does not explain the parameter's format (IP, hostname, SNMP community) or any constraints, leaving agents to infer meaning solely from the schema type.

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 tool reports printer status via PRINTER-MIB (RFC 3805) covering supplies, trays, bins, alerts, and supports multiple brands. It includes handling of sentinel values, making the purpose specific and distinct from sibling tools like system_info or interfaces_list.

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?

No explicit guidance on when to use this tool over alternatives (e.g., snmp_walk, snmp_get) or prerequisites like SNMP configuration. The description only lists supported printer brands but does not differentiate use cases.

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