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

Beyond the annotations (readOnly, openWorld, idempotent), the description adds concrete behavioral details: it is 'read-only, free, keyless', 'performs nothing and asks for nothing', requires no balance or gas, and never sees the key during local wallet generation. These details meaningfully inform an agent's expectations about side effects and prerequisites.

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 front-loaded with the core purpose and each sentence adds useful context. It is slightly verbose with conceptual phrases like 'ecological wealth is provisioned by work', but overall it is efficiently structured for an onboarding 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?

Given the tool has no parameters, an output schema, and rich annotations, the description covers everything needed: what the tool surfaces, what it explains, that it requires no wallet/balance/gas, and that it has no side effects. Nothing essential is missing 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?

With zero parameters and 100% schema coverage, the baseline is high, but the description still reinforces the no-input nature by stating it is keyless and 'asks for nothing'. This is valuable for an agent deciding whether any setup or arguments are needed before invoking the tool.

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 uses a specific, vivid framing—'the door for an agent arriving with nothing'—and clearly states the resource: the front-door set of physical work packets plus explanation of wallet generation. It distinguishes itself from the many operational siblings by explicitly saying it 'performs nothing and asks for nothing', making it unmistakably an onboarding/overview tool rather than a work or transaction tool.

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 gives clear context: use this when you have no wallet and no money, and it talks about ordinary work with no licence, equipment, or supervisor. It does not explicitly name alternatives or say when not to use it, but the title 'start here' and 'front-door' phrasing make the intended entry-point usage evident.

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