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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses very little. It implies a read-only listing but says nothing about pagination, result ordering, what an empty wallet returns, or whether the wallet must be a registered identity; only the chain support is recoverable, and that is already in the schema.

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?

One front-loaded sentence with no padding; verb, resource and scope arrive in the first few words. It is efficient, though the brevity leaves no room for the routing hints a list tool in a large sibling group benefits from.

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 two-parameter read tool with a fully documented schema and no output schema, the description is minimally sufficient: the agent knows what is returned (Agent IDs) in broad terms. Missing are return-shape detail, empty-result behavior, and differentiation from actora_identity_list_all, which the tool's complexity level would reasonably accommodate.

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%, including an enum for chain with a stated default and a note that Sepolia is unsupported, so the schema already does the parameter work. The description adds only that ownerAddress identifies a wallet whose agents are returned and lists the three chains, both of which restate structured fields.

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?

States a specific verb (list) and resource (Agent IDs), plus the scoping dimension (owned by a wallet address) and the supported chains. An agent can distinguish it from actora_identity_get or actora_identity_exists, though it never names the closest sibling actora_identity_list_all, so the differentiation is inferred rather than stated.

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?

There is no explicit when-to-use or when-not-to-use guidance and no mention of alternatives such as actora_identity_list_all or actora_identity_get. The agent must infer from the name and the required ownerAddress that this is the per-wallet lookup, which is a thinner signal than the sibling set warrants.

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