register_agent

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

No annotations are provided, so the description must disclose behavioral traits. It only implies state change ('register') but does not mention side effects like gas costs, uniqueness constraints, or success/failure conditions. The optional tx_hash parameter hints at recovery but is not explained.

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 a single, front-loaded sentence that efficiently communicates the core purpose. It is concise but at the cost of omitting necessary details about usage and behavior.

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 no output schema, no annotations, and 75% schema coverage, the description fails to provide essential context. It does not explain what the tool returns, prerequisites, or side effects. A registration tool requires more detail to be usable.

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 coverage is 75% (3 of 4 params described). The description adds no additional meaning beyond the schema's parameter descriptions. Baseline is 3 since schema does the heavy lifting.

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 action ('register'), the resource ('AI agent'), and the mechanism ('on-chain (ERC-8004)'). It distinguishes from sibling tools like list_agents and is_agent_registered which are query-only.

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 provides no guidance on when to use this tool, prerequisites, or alternatives. It does not explain if the agent must already exist, if wallet connection is needed, or how it differs from registration-like tools in other contexts.

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