Verify Registration

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

No annotations provided, so description carries full burden. It discloses that the tool returns an API key, upgrades the session to authenticated, and that no authentication is required to call it. It also notes that after verification, authenticated tools work in the session without reconnecting. This is good behavioral context for a state-changing tool.

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?

Three concise sentences, front-loaded with the primary purpose. No redundant or unnecessary information. Every sentence adds value.

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?

No output schema, but description states it returns an API key. Explains the before/after state of the session. Parameters are fully documented in schema with additional context from description. Sufficient for an agent to understand how to invoke it.

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?

All three parameters have schema descriptions, and the tool description adds valuable context: 'address' must match the register call, 'signature' is from tronWeb.trx.signMessageV2, and 'challengeId' comes from the register tool. This explains the workflow and parameter origins beyond 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 clearly states the tool's purpose: 'Complete agent registration by verifying your signed challenge. Returns an API key and upgrades the current session to authenticated.' It identifies the resource (agent registration) and the action (verify) with specific outcomes. Differentiates from siblings like 'register' by explaining it's the verification step.

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 explains when to use the tool: after 'register', before using authenticated tools. It lists examples of tools that become available ('buy_energy, get_balance, register_pool, etc.'). No explicit when-not or alternatives, but given the sequential nature of registration, it's sufficiently clear.

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