edit_user_profile

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

No annotations are provided, and the description fails to disclose behavioral traits such as idempotency, permission requirements, or side effects. The description only says 'Edit a user's profile data', offering no insight into how the tool behaves—whether it overwrites fields, requires specific roles, or returns the updated profile.

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?

The description is a single sentence, which is concise but overly brief for a tool with six parameters and no other documentation. It does not waste words, but it fails to convey essential information. A bit more detail would improve utility without sacrificing conciseness.

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 complexity (6 parameters, 1 required, enums, no output schema, no annotations), the description is incomplete. It does not set expectations for success/error handling, or what fields are allowed. The agent lacks sufficient information to invoke the tool confidently.

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%, meaning the input schema provides no descriptions for the six parameters. The description adds no explanation for parameters like 'username', 'home_page', or 'curr_abbr'. For example, 'curr_abbr' is a currency code enum, but the description does not clarify its purpose. This leaves the agent guessing about parameter meaning.

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 states verb 'edit' and resource 'user's profile data' which clearly indicates the action and target. However, among sibling tools like 'edit_item_in_wantlist' and 'edit_marketplace_order', there is no differentiation to distinguish what constitutes 'profile data' versus other editable entities. A more specific description (e.g., listing the fields) would help.

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. The description does not mention prerequisites, context, or when it is appropriate to use this tool. With many edit sibling tools, lack of usage context reduces the agent's ability to select this tool correctly.

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