Ping

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: it says nothing about timeouts, latency, what a failed ping means, or what happens when a federated device is unreachable.

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?

A single front-loaded sentence with no filler; it is appropriately sized for a simple probe tool. It does not pad or bury the point.

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 low-complexity ping tool with annotations covering safety and no output schema, the description is broadly adequate. However, the two parameters remain entirely undefined in both schema and description, which is a real gap for target selection.

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% and neither parameter (deviceId, deviceName) is explained in the description. The phrase 'configured federated device' hints that a device can be targeted, but it doesn't clarify how deviceId/deviceName select that target or what happens if both are omitted.

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 a specific verb (verify) and resource (Raccoon online status) with scope ('locally or on a configured federated device'). It is clear on its own, though it does not distinguish itself from siblings like system_info or who_am_i, which also relate to environment/identity checks.

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 is only implied: an agent can infer this is a connectivity/health check before other operations, but the description gives no explicit when-to-use, exclusions, or named alternatives relative to the many sibling tools.

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