Unraid API isFreshInstall

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

Annotations already mark it readOnly, idempotent, and non-destructive, so no side effects need restating. The description adds the precise behavioral condition checked ('no license key') and implies a boolean outcome via 'Check whether'. It does not overpromise side effects or contradict 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 declarative sentence that front-loads the query action and the condition; no filler or repeated title.

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 zero-parameter read-only predicate, the description supplies the essential semantics and even defines the 'fresh install' condition. It does not explicitly state the return type, but 'Check whether' sufficiently implies a boolean; this is a minor gap given the tool's simplicity.

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 already covers 100%, so there is nothing for the description to add. Baseline of 4 applies for zero-parameter tools.

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 uses a specific verb ('Check whether') and states the exact resource condition ('server has no license key'), which maps directly to the tool name. This distinguishes it from other query siblings that check registration, info, or config.

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 sentence indicates when to prefer this tool over alternatives such as unraid_v4371_query_registration or unraid_v4371_query_info, nor any exclusions. The only context is the purpose itself, so an agent must infer when the check is appropriate.

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