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

The description explicitly frames this as a 'Read' of the user's saved profile, while the annotations declare readOnlyHint=false. A pure read should be read-only, so the description and the structured safety metadata point in opposite directions, leaving the agent unable to tell whether calling this tool mutates state. This is an annotation contradiction.

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?

A single front-loaded sentence containing the verb, the resource and the authorization requirement. There is no filler and nothing to trim.

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?

An output schema exists, so return values need no explanation, and with no parameters the schema carries no burden. What is missing is behavioral framing: the description does not reconcile its 'Read' claim with readOnlyHint=false, nor does it say when to prefer this over the other *_get tools.

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 zero parameters, so there is nothing for the description to disambiguate. The default baseline of 4 applies; the permission note adds useful invocation context that the empty schema cannot express.

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 and resource: 'Read the connected user's saved 引力AI profile.' That cleanly separates it from siblings like fitmeet_notifications_get, fitmeet_group_get and fitmeet_connection_feedback_get, which fetch different resources. It stops short of an explicit contrast with those siblings, but the resource scope is unambiguous.

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 supplies one real usage constraint — the caller needs profile:read permission — which helps an agent decide whether it can invoke the tool. It gives no when-to-use guidance relative to the other read tools, and no statement of what to call when the permission is absent.

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