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

Beyond the readOnlyHint/openWorldHint annotations, the description adds real behavioral context: the caller must have an active plan, the token lasts 72 hours, it is free, and it must be fed to `ignix-editor license <token>`. It stops short of describing the exact return shape, but that is minor for a single-token response.

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?

Three sentences, front-loaded with the eligibility prerequisite (active plan) and immediately followed by the usage trigger and lifecycle. Slightly dense but every clause carries information; no filler.

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 tool with no output schema and annotations already covering the safety profile, the description supplies everything needed: prerequisite, invocation timing, token lifetime, and the command to consume the result.

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 the baseline for this dimension is 4. There is nothing for the description to clarify beyond the schema's empty object.

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 (get) and resource (Editor license/token) and names the exact product it serves (Ignix Editor), so the agent knows precisely what the call yields. It is fully unambiguous, though it does not need to differentiate against siblings since no other tool grants an editor license.

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 explicit trigger conditions: call once before the first ignix-editor command of a session, and re-call when the Editor reports the token expired. Both the when and the repeat-when are spelled out, leaving nothing to inference.

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