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

The description adds vital behavioral constraints, specifically stating that 'The target wallet is ALWAYS the authenticated agent's bound operating wallet — it is never taken from the input,' which is a critical safety and functional detail beyond the provided 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?

While long, the description is perfectly dense and highly structured, using numbered steps (1-2-3) to convey complex logic without any wasted words.

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?

Given the technical complexity of the workflow, the description is maximally complete. It defines the actors, the constraints, the necessary preconditions (the 3-minute code window), and the expected state changes.

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 schema coverage is 100%, the description doesn't need to define parameters but does elaborate on the nature of the linkCode (8-character, 3-minute expiry) and its use in the overall ceremony. This is sufficient context when structure is already perfect.

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 identifies the resource (agent's operating wallet) and the goal (linking it to the owner's identity), avoiding vagueness and detailing its specific role in the linking workflow.

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 provides excellent usage guidelines by laying out a mandatory three-step process, explicitly naming the required preceding and succeeding tools in the process. This prevents functional misuse.

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