Get a Fresh Setup Link

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

The description discloses the behavior beyond neutral annotations: it creates a fresh link for unclaimed agents and reports no link for claimed ones. It also indicates the response should be given to the operator, adding practical side-effect context not covered by 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?

Two concise sentences with zero fluff. The condition and action are front-loaded in the first sentence, and the outcome in the second. Every word earns its place, making it highly efficient.

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, the description is complete: it states when to call, what it does, and how to handle the result (give URL to operator). It even covers the edge case of already-claimed agents, leaving no gaps for correct invocation.

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?

Since the tool has no parameters, the schema is trivially 100% covered. The description adds value by explaining the result of calling, but there are no parameters to document. Baseline for zero params is 4, which is appropriate.

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 clearly states the tool's action: issue a fresh 24-hour setup link, and the exact conditions (agent unclaimed, setup_url lost/expired). It distinguishes this from general setup by specifying the scenario, making its purpose unmistakable.

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?

Provides explicit when-to-use conditions (if unclaimed and setup_url lost/expired) and when-not-to-use (if already claimed, reports no link needed). This leaves no ambiguity about context, effectively guiding the agent on when to invoke it.

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