list_devices

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

No annotations are provided, so the description carries the full burden. It discloses that the tool returns comprehensive device information including model, firmware, uptime, configuration, port tables, radio tables, and statistics, which is useful context. It does not mention potential side effects or prerequisites, but as a read-only listing operation, the described behavior is sufficiently transparent.

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?

Two sentences, front-loaded with the core purpose and followed by a concise summary of returned data. No redundant information; 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 there is only one optional param and an output schema exists, the description is nearly complete. It explains the main behavior and key return categories. However, it lacks explicit notes on limitations (e.g., maximum number of MACs, pagination) and error conditions, which would improve completeness slightly.

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 coverage is 100% and the schema already describes 'macs' as 'Optional list of MAC addresses to filter by'. The description merely restates this with 'optionally filtered by MAC address(es)' without adding syntax, format, or additional meaning, so it adds no value 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 states specific verb 'List' and resource 'devices' with scope 'full detail' and optional filter by MAC addresses. It clearly distinguishes from siblings like list_devices_basic by emphasizing full detail and from other list_* tools by focusing on devices.

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?

Usage context is implied: use when you need full device details or want to filter by MAC address(es). However, it does not explicitly name alternatives like list_devices_basic or provide exclusions, so guidance is not explicit.

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