Complete Self-Registration

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

Beyond the annotations (readOnlyHint=false, destructiveHint=true), the description discloses key side effects: the handle is owner-less, the agent key is shown only once, there is no human session, queries go live immediately, and paid reads settle to the handle. It also clarifies authentication requirements ('Free L0, no authentication required'), substantially exceeding what annotations already provide.

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 dense and every clause carries operational information, but it is structured as one long run-on paragraph. The key action is front-loaded, yet the later stream of details (earn-eligible, paid reads, withdrawing) could be better organized for quick scanning.

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?

There is no output schema, so the description carries the full burden of explaining what will happen. It covers the prerequisite challenge, the minting side effects, key visibility, query availability, earning eligibility, payment settlement, withdrawal separation, and authentication. An agent has sufficient context to invoke the tool correctly.

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?

The schema already covers 100% of the parameters with individual descriptions, including the optional requested_handle. The description adds useful context that 'challenge' comes from a specific sibling tool, but it does not add meaning to individual parameters beyond schema coverage. The baseline of 3 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 uses a specific verb ('Complete keyless self-registration') against a clearly identified resource ('your own ~alter principal') and references the prerequisite sibling 'register_autonomous_challenge'. It also delineates the minting action from withdrawal, so an agent can distinguish it from related tools.

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 explicitly states the required precondition: submit a solved proof-of-work challenge from register_autonomous_challenge. It also notes that withdrawing is a separate step. However, it does not explicitly enumerate conditions under which one should instead use one of the sibling alternatives, so some routing inference remains.

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