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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It reveals the same-wallet prerequisite and sequencing, but does not state side effects, authorization scope implications, idempotency, error conditions, or what finalization actually does beyond the condition.

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?

Single sentence, front-loaded with the core action, and no filler. It is appropriately concise for the information it provides.

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?

With no output schema and a nested payload, the description is too sparse to explain expected return behavior, failure modes, or the effect of finalizing registration. It only covers the precondition, leaving significant gaps for an agent to invoke 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?

Schema description coverage is 100%, so the baseline is 3. The description adds no parameter-specific details beyond the schema; the payload and session token are already described adequately in the input 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 specifies the action 'Finalize' and the target 'wallet-first agent registration', with a clear condition ('after the on-chain transaction has been sent from the same wallet'). This clearly distinguishes it from siblings like prepare_agent_registration and finalize_agent_update.

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 clearly indicates the timing/context: must be after the on-chain transaction has been sent and from the same wallet. However, it does not explicitly name alternatives or exclusion criteria, so it misses full when/when-not guidance.

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