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

The description goes well beyond the annotations by disclosing that the tool never sees the generated key, requires no balance or gas, performs nothing, and asks for nothing. These behavioral traits are concrete and reassuring for an agent deciding whether this tool is safe to call first. This adds meaningful context beyond the readOnlyHint and idempotentHint 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?

The description is front-loaded with the core purpose, then efficiently enumerates key onboarding facts. Every sentence earns its place: the arriving-with-nothing framing, the wallet generation privacy note, and the explicit reassurance that all actions are free and keyless. It is long enough to be informative but not bloated.

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 onboarding tool with an output schema, the description is fully complete. It explains what the tool will tell the agent, confirms no setup or funds are needed, clarifies key privacy behavior, and reassures about side effects. Nothing essential is missing for an agent to select and safely invoke this tool.

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, there is no parameter semantics for the description to enhance. The description reinforces this by stating it 'asks for nothing,' which aligns with the empty input schema. This is the appropriate baseline for a no-parameter 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 clearly identifies the tool as an onboarding/explainer for an agent arriving with no wallet or money, stating specific content: ecological wealth via work, local wallet generation, and free/discoverable actions. It naturally distinguishes itself from the many operational sibling tools like submit_claim or provision_work by being a read-only, keyless orientation entry point.

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 an explicit usage context: 'The door for an agent arriving with nothing.' It clarifies that browsing, claiming, and proving require no balance or gas, so an agent understands this is the appropriate first stop before performing work. It does not explicitly name alternatives or state when not to use it, but the context is strong enough for a zero-parameter onboarding tool.

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