discover_lan_devices

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

Annotations provide idempotentHint true and destructiveHint false. The description adds 'reconcile identities,' implying state changes, but lacks further context on side effects or prerequisites. Adequate given annotations.

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?

Single sentence, no fluff, front-loaded with action. Could be clearer but efficient for a single-parameter tool.

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?

Output schema covers return values, annotations cover safety. Description omits usage scenarios and parameter constraints, but overall adequate for a simple discovery tool with a single optional parameter.

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 compensates by noting target may be an IP/broadcast address. However, it omits format, required vs optional, and default behavior, leaving gaps.

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 states the tool scans LAN ACs and reconciles identities, providing a specific verb and resource. It distinguishes from siblings like list_devices (known devices) by focusing on discovery, though 'LAN ACs' is somewhat cryptic.

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 versus alternatives like list_devices or get_device. The context of target being an IP/broadcast address is implied but not elaborated.

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