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

It discloses that the token is public and that no financial incentive is involved. However, with no meaningful annotation coverage (all hints false), the description does not explain side effects, token lifetime, permissions represented by controller_token, or whether repeated calls create duplicates.

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?

The description is two tight sentences with no wasted words. It front-loads the primary action and then adds the clarifying non-payment detail, which directly affects whether an agent should select this tool.

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?

The description provides only a high-level purpose and omits enough operational context for confident invocation: no parameter guidance, no relationship to accept_relay, no mention of required authentication context, and no indication of what the output represents. The output schema exists, but it does not fill these gaps from the agent's perspective.

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?

Schema description coverage is 0%, and the description does not compensate by explaining any of the three parameters: profile_id, controller_token, or channel. The agent must infer their meaning entirely from names, patterns, and constraints in the schema.

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 and resource: 'Create a public attribution token for sharing Helena Good with another agent.' The additional clarification about no payment, commission, or tokenized reward helps distinguish this from related tools like sponsor_campaign and accept_relay.

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?

The description implies when to use it—when you want to create an attribution token for sharing Helena Good—but it does not explicitly name alternatives or state when not to use it. The 'No payment...' note is a useful exclusion but does not provide full routing guidance.

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