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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint false and openWorldHint false, so the safety profile is fully covered and the description adds little there. It contributes the notion that the returned id is stable and opaque, which usefully signals that the value should not be parsed or expected to change, but the return-shape detail is largely redundant with the existing output 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?

Two short sentences, with the purpose front-loaded and the return payload following. Every clause carries information, and nothing is padded or restated from the title.

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?

This is a nullary, read-only lookup with a rich annotation set and an output schema, so the description covers everything an agent needs in order to call it. The only omission is failure behavior, such as what happens when no account is associated with the connection.

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 tool takes no parameters, so the baseline is 4; there is nothing in the input schema for the description to explain. No parameter-level claims are made and none are needed.

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 states a specific verb and resource: identify the MyClawn account behind this connection. It also names the payload, a stable opaque id plus the clone's display name, so the agent knows what identifying means here. It does not explicitly distinguish itself from the similarly named get_my_clone sibling, which is the only gap.

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?

"Use this to identify the MyClawn account behind this connection" implies a when-to-use context, namely identity resolution before acting on the account. However, it offers no exclusions or alternatives, and it does not clarify how it differs from get_my_clone, which a reader would reasonably expect to overlap.

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