Licensing

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description's added value is the inventory of what actually comes back (license type subscription/perpetual, expiration date, seat count, usage, activation status), which is genuinely useful given there is no output schema. It does not mention permissions or freshness, so not a 5.

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, no filler. The resource is front-loaded and the enumerable return fields are listed compactly, followed by the usage triggers. Every clause 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?

With no output schema and no inputs, the description is the only place an agent can learn what this call yields, and it lists the major fields. It does not spell out the shape (e.g., single object vs. per-server rows) or whether unlicensed state returns an error, leaving minor gaps.

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 takes zero parameters, so there is nothing for the description to disambiguate. A 4 is the baseline for a parameterless tool, and the description correctly avoids inventing filtering options that the schema does not support.

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 names a specific resource (RAS licensing status) and enumerates the exact facets it exposes: license type, expiration, seat count, usage, activation status. This cleanly separates it from sibling 'get_*' tools like ras_farm_get_config or ras_farm_get_version. It lacks an explicit contrast sentence against those siblings, which keeps it short of a 5.

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?

It gives concrete scenarios for invocation: check compliance, verify capacity, diagnose licensing issues. That is clear context for when to reach for this tool, but no exclusions or named alternatives (e.g., 'use ras_farm_get_administrators for account-level issues'), so it stops at 4.

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