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

Annotations declare destructiveHint=true and openWorldHint=true, but the description never addresses that profile data can be overwritten, whether the change is reversible, or whether authentication is implied. 'and/or' is the only behavioral hint (partial update), which is thin for a mutation flagged destructive.

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 short sentence with the action and the affected fields front-loaded. Nothing is padded or redundant; every word earns its place.

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 not be explained. However, for a destructive-flagged mutation with zero parameter documentation, the description omits permission requirements and the effect on unmentioned profile fields, leaving meaningful gaps.

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 0% and neither parameter has a description, so the description carries some burden. It does map 'first and/or last name' onto firstName/lastName and implies both are optional, but adds no format or constraint details beyond that mapping.

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 (update) and resource (current user's profile), and names the exact fields touched (first/last name). It is clear on its own, but it does nothing to distinguish itself from siblings like get_my_profile or update_account_member_role.

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?

No when-to-use guidance and no alternatives named. The sibling list contains update_account_member_role and get_my_profile, and the description gives no cue about when this self-service update is appropriate versus those.

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