Update Profile

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

No annotations are provided, so the description carries full burden. It mentions 'Update' implying mutation but does not disclose side effects, auth requirements, or whether partial updates are supported (i.e., only provided fields are updated). No mention of response behavior.

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?

Single sentence, front-loaded with action and resource. No unnecessary words. Very concise and to the point.

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 the tool has 2 optional parameters and no output schema, the description is minimal but marginally adequate. However, it lacks clarity on partial updates and does not mention that only the current user's profile is affected, leaving room for ambiguity.

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?

Input schema covers 100% of parameters with descriptions ('Display name', 'Avatar URL'), so baseline is 3. Description adds no semantic value beyond naming the overall resource ('profile information'). No additional context on parameter constraints or relationships.

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?

Description clearly states the tool updates the current user's profile information. It is specific about the action (update) and resource (current user's profile), and effectively distinguishes from sibling tools that update other entities like documents or workspaces.

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 guidance on when to use this tool versus alternatives. While siblings include sign_in and current_user, the description does not specify that this tool is for modifying the authenticated user's profile or that it requires authentication.

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